篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Android Glide Google 推荐加载图片框架（加载图片详解篇）相关的知识，希望对你有一定的参考价值。

 看到这个，你一定会说，我现在在用ImageLoader，Picasso，Fresco或其它框架中的图片加载，都挺好用的，为什么要选用Glide呢？
   答：因为是Google推荐的。（不要打我，我说的是实话）

看这篇译文图片加载框架介绍 
和Picasso有90%相似度，但却比Picasso省内存。如果你注重app的优化，注重内存的管理，可以转换使用Glide来加载图片。

下面来总结一下Glide加载图片过程中的方法。（都很有用哦）

1.从本地资源中加载：

<code class="hljs avrasm has-numbering" style="display: block; padding: 0px; background-color: transparent; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-top-left-radius: 0px; border-top-right-radius: 0px; border-bottom-right-radius: 0px; border-bottom-left-radius: 0px; word-wrap: normal; background-position: initial initial; background-repeat: initial initial;">int resourceId = R<span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.mipmap</span><span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.ic</span>_launcher<span class="hljs-comment" style="color: rgb(136, 0, 0); box-sizing: border-box;">;</span>
Glide
    <span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.with</span>(context)
    <span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.load</span>(resourceId)
    <span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.into</span>(imageViewResource)<span class="hljs-comment" style="color: rgb(136, 0, 0); box-sizing: border-box;">;</span></code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; background-color: rgb(238, 238, 238); top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right;"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li><li style="box-sizing: border-box; padding: 0px 5px;">5</li></ul>

2.从文件中加载：

//这个文件可能不存在于你的设备中。然而你可以用任何文件路径，去指定一个图片路径。

<code class="hljs vhdl has-numbering" style="display: block; padding: 0px; background-color: transparent; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-top-left-radius: 0px; border-top-right-radius: 0px; border-bottom-right-radius: 0px; border-bottom-left-radius: 0px; word-wrap: normal; background-position: initial initial; background-repeat: initial initial;"><span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">File</span> <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">file</span> = <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">new</span> <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">File</span>(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES), <span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"Running.jpg"</span>);
Glide
    .<span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">with</span>(<span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">context</span>)
    .load(<span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">file</span>)
    .into(imageViewFile);</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; background-color: rgb(238, 238, 238); top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right;"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li><li style="box-sizing: border-box; padding: 0px 5px;">5</li></ul>

3.从Uri中加载：

//这可能是任何 Uri。为了演示的目的我们只是用一个 launcher icon 去创建了一个 Uri

<code class="hljs avrasm has-numbering" style="display: block; padding: 0px; background-color: transparent; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-top-left-radius: 0px; border-top-right-radius: 0px; border-bottom-right-radius: 0px; border-bottom-left-radius: 0px; word-wrap: normal; background-position: initial initial; background-repeat: initial initial;">Uri uri = resourceIdToUri(context, R<span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.mipmap</span><span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.future</span>_studio_launcher)<span class="hljs-comment" style="color: rgb(136, 0, 0); box-sizing: border-box;">;</span>
Glide
    <span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.with</span>(context)
    <span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.load</span>(uri)
    <span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.into</span>(imageViewUri)<span class="hljs-comment" style="color: rgb(136, 0, 0); box-sizing: border-box;">;</span></code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; background-color: rgb(238, 238, 238); top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right;"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li><li style="box-sizing: border-box; padding: 0px 5px;">5</li></ul>

4.listView GridView 加载不会出现图片错位的情况。并自带三级缓存。

5.占位图的展示：placeholder（）

<code class="hljs avrasm has-numbering" style="display: block; padding: 0px; background-color: transparent; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-top-left-radius: 0px; border-top-right-radius: 0px; border-bottom-right-radius: 0px; border-bottom-left-radius: 0px; word-wrap: normal; background-position: initial initial; background-repeat: initial initial;">Glide
    <span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.with</span>(context)
    <span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.load</span>(R<span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.mipmap</span><span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.ic</span>_launcher)
    <span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.placeholder</span>(R<span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.mipmap</span><span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.ic</span>_launcher) // 设置在加载图片过程图显示的占位图
    <span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.into</span>(imageViewPlaceholder)<span class="hljs-comment" style="color: rgb(136, 0, 0); box-sizing: border-box;">;</span></code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; background-color: rgb(238, 238, 238); top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right;"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li><li style="box-sizing: border-box; padding: 0px 5px;">5</li></ul>

6.错误占位符： .error()

<code class="hljs avrasm has-numbering" style="display: block; padding: 0px; background-color: transparent; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-top-left-radius: 0px; border-top-right-radius: 0px; border-bottom-right-radius: 0px; border-bottom-left-radius: 0px; word-wrap: normal; background-position: initial initial; background-repeat: initial initial;">Glide
    <span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.with</span>(context)
    <span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.load</span>(<span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"http://futurestud.io/non_existing_image.png"</span>)
    <span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.placeholder</span>(R<span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.mipmap</span><span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.ic</span>_launcher) // can also be a drawable
    <span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.error</span>(R<span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.mipmap</span><span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.future</span>_studio_launcher) // 图片加载错误时候的加载
    <span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.into</span>(imageViewError)<span class="hljs-comment" style="color: rgb(136, 0, 0); box-sizing: border-box;">;</span></code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; background-color: rgb(238, 238, 238); top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right;"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li><li style="box-sizing: border-box; padding: 0px 5px;">5</li><li style="box-sizing: border-box; padding: 0px 5px;">6</li></ul>

7.加载图片时候淡入淡出动画 ：crossFade();（这个效果在3.6.1版是默认激活的）

<code class="hljs avrasm has-numbering" style="display: block; padding: 0px; background-color: transparent; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-top-left-radius: 0px; border-top-right-radius: 0px; border-bottom-right-radius: 0px; border-bottom-left-radius: 0px; word-wrap: normal; background-position: initial initial; background-repeat: initial initial;">Glide
    <span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.with</span>(context)
    <span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.load</span>(UsageExampleListViewAdapter<span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.eatFoodyImages</span>[<span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">0</span>])
    <span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.placeholder</span>(R<span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.mipmap</span><span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.ic</span>_launcher) // can also be a drawable
    <span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.error</span>(R<span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.mipmap</span><span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.future</span>_studio_launcher) // will be displayed if the image cannot be loaded
    <span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.crossFade</span>()//增加图片显示时候的淡入淡出动画
    <span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.into</span>(imageViewFade)<span class="hljs-comment" style="color: rgb(136, 0, 0); box-sizing: border-box;">;</span></code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; background-color: rgb(238, 238, 238); top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right;"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li><li style="box-sizing: border-box; padding: 0px 5px;">5</li><li style="box-sizing: border-box; padding: 0px 5px;">6</li><li style="box-sizing: border-box; padding: 0px 5px;">7</li></ul>

8.直接加载不要淡入淡出效果：dontAnimate();

<code class="hljs avrasm has-numbering" style="display: block; padding: 0px; background-color: transparent; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-top-left-radius: 0px; border-top-right-radius: 0px; border-bottom-right-radius: 0px; border-bottom-left-radius: 0px; word-wrap: normal; background-position: initial initial; background-repeat: initial initial;">Glide
    <span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.with</span>(context)
    <span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.load</span>(UsageExampleListViewAdapter<span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.eatFoodyImages</span>[<span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">0</span>])
    <span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.placeholder</span>(R<span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.mipmap</span><span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.ic</span>_launcher) // can also be a drawable
    <span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.error</span>(R<span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.mipmap</span><span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.future</span>_studio_launcher) // will be displayed if the image cannot be loaded
    <span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.dontAnimate</span>()//取消淡入淡出效果
    <span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.into</span>(imageViewFade)<span class="hljs-comment" style="color: rgb(136, 0, 0); box-sizing: border-box;">;</span></code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; background-color: rgb(238, 238, 238); top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right;"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li><li style="box-sizing: border-box; padding: 0px 5px;">5</li><li style="box-sizing: border-box; padding: 0px 5px;">6</li><li style="box-sizing: border-box; padding: 0px 5px;">7</li></ul>

9.resize(x,y) 调整图片大小 override(horizontalSize,verticalSize)

<code class="hljs sql has-numbering" style="display: block; padding: 0px; background-color: transparent; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-top-left-radius: 0px; border-top-right-radius: 0px; border-bottom-right-radius: 0px; border-bottom-left-radius: 0px; word-wrap: normal; background-position: initial initial; background-repeat: initial initial;">Glide
    .with(context)
    .<span class="hljs-operator" style="box-sizing: border-box;"><span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">load</span>(UsageExampleListViewAdapter.eatFoodyImages[<span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">0</span>])
    .override(<span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">600</span>, <span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">200</span>) // resizes the image <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">to</span> these dimensions (<span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">in</span> pixel). does <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">not</span> respect aspect ratio
    .<span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">into</span>(imageViewResize);</span>
(设置图片大小，可能导致图片失真变形)</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; background-color: rgb(238, 238, 238); top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right;"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li><li style="box-sizing: border-box; padding: 0px 5px;">5</li><li style="box-sizing: border-box; padding: 0px 5px;">6</li></ul>

10.CenterCrop 和FitCenter,看到这俩属性，你一定想到了ImageView 也有同样的属性，就是为了按照需要缩放图片。

<code class="hljs avrasm has-numbering" style="display: block; padding: 0px; background-color: transparent; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-top-left-radius: 0px; border-top-right-radius: 0px; border-bottom-right-radius: 0px; border-bottom-left-radius: 0px; word-wrap: normal; background-position: initial initial; background-repeat: initial initial;">Glide

12.显示本地视频

<code class="hljs vhdl has-numbering" style="display: block; padding: 0px; background-color: transparent; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-top-left-radius: 0px; border-top-right-radius: 0px; border-bottom-right-radius: 0px; border-bottom-left-radius: 0px; word-wrap: normal; background-position: initial initial; background-repeat: initial initial;"><span class="hljs-typename" style="color: rgb(102, 0, 102); box-sizing: border-box;">String</span> filePath = <span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"/storage/emulated/0/Pictures/example_video.mp4"</span>;

13.图片加载缓存（内存缓存） .skipMemoryCache(true).

该方法将告诉glide跳过内存缓存，就是不将图片缓存到内存缓存中。

<code class="hljs sql has-numbering" style="display: block; padding: 0px; background-color: transparent; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-top-left-radius: 0px; border-top-right-radius: 0px; border-bottom-right-radius: 0px; border-bottom-left-radius: 0px; word-wrap: normal; background-position: initial initial; background-repeat: initial initial;">Glide

14.图片加载缓存（磁盘缓存）

.diskCacheStrategy(),参数需要一个枚举类型的，而不是一个布尔类型。 
.diskCacheStrategy(DiskCacheStrategy.NONE);

<code class="hljs avrasm has-numbering" style="display: block; padding: 0px; background-color: transparent; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-top-left-radius: 0px; border-top-right-radius: 0px; border-bottom-right-radius: 0px; border-bottom-left-radius: 0px; word-wrap: normal; background-position: initial initial; background-repeat: initial initial;">Glide  
    <span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.with</span>( context )
    <span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.load</span>( eatFoodyImages[<span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">0</span>] )
    <span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.diskCacheStrategy</span>( DiskCacheStrategy<span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.NONE</span> )
    <span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.into</span>( imageViewInternet )<span class="hljs-comment" style="color: rgb(136, 0, 0); box-sizing: border-box;">;</span></code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; background-color: rgb(238, 238, 238); top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right;"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li><li style="box-sizing: border-box; padding: 0px 5px;">5</li></ul>

15.自定义磁盘缓存（磁盘缓存）

Glide加载图片和Picasso加载图片有百分之90%的相似度，但是Glide占用内存不足Picasso的一半（据说图片会稍微不清晰，但是肉眼看不出来（我是没看出来）） 
在缓存方面，Picasso缓存的是整张高清图片，而Glide缓存原始图的同时，缓存加载出来的图片（比如你的图片是1000*1000，加载到ImageView 中的图片是500*500），这个时候，Glide会将1000*1000和500*500两个参数都进行缓存。

这个时候的就要看.diskCacheStrategy() 方法中几个枚举参数了（看12） 
DiskCacheStrategy.NONE 什么都不缓存，就像刚讨论的那样 
DiskCacheStrategy.SOURCE 仅仅只缓存原来的全分辨率的图像。在我们上面的例子中，将会只有一个 1000x1000 像素的图片 
DiskCacheStrategy.RESULT 仅仅缓存最终的图像，即，降低分辨率后的（或者是转换后的） 
DiskCacheStrategy.ALL 缓存所有版本的图像（默认行为） 
一目了然，磁盘缓存就搞定了。可以缓存原图，可以缓存处理过的图。吊炸天 
（备注：3.6.1以及最新的3.7.0 .diskCacheStrategy()默认都是DiskCacheStrategy.RESULT）

16.自定义图片加载优先级 .priority()方法。

介绍：当你要加载图片的时候，希望某些图片先加载，某些图片之后加载，这个时候调用.priority()方法，其参数为枚举类型。 
所包含的参数递增的方式（优先级越来越高）排列：

<code class="hljs avrasm has-numbering" style="display: block; padding: 0px; background-color: transparent; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-top-left-radius: 0px; border-top-right-radius: 0px; border-bottom-right-radius: 0px; border-bottom-left-radius: 0px; word-wrap: normal; background-position: initial initial; background-repeat: initial initial;">Priority<span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.LOW</span>
Priority<span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.NORMAL</span>
Priority<span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.HIGH</span>
Priority<span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.IMMEDIATE</span></code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; background-color: rgb(238, 238, 238); top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right;"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li></ul>

设置了这个参数，系统会尽可能的按照你的意愿去加载图片（就是可能因为某些规则，不按你设置的规则走）

17.设置缩略图 .thumbnail() 传入float参数作为其大小的倍数。

<code class="hljs avrasm has-numbering" style="display: block; padding: 0px; background-color: transparent; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-top-left-radius: 0px; border-top-right-radius: 0px; border-bottom-right-radius: 0px; border-bottom-left-radius: 0px; word-wrap: normal; background-position: initial initial; background-repeat: initial initial;">Glide  
    <span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.with</span>( context )
    <span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.load</span>( UsageExampleGifAndVideos<span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.gifUrl</span> )
    <span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.thumbnail</span>( <span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">0.1</span>f ) //加载缩略图  为原图的十分之一
    <span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.into</span>( imageView2 )<span class="hljs-comment" style="color: rgb(136, 0, 0); box-sizing: border-box;">;</span></code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; background-color: rgb(238, 238, 238); top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right;"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li><li style="box-sizing: border-box; padding: 0px 5px;">5</li></ul>

备注：使用缩略图的话，就要考虑ImageView 确保ScaleType 的属性问题。要不然加载出来的图片会很小。

上面的可能是要加载一个网络图片，即使是缩略图，也要先从网络上拿到图片，才能变成缩略图进行展示。所以我们也可以加载本地的一张图片的缩略图。

<code class="hljs avrasm has-numbering" style="display: block; padding: 0px; background-color: transparent; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-top-left-radius: 0px; border-top-right-radius: 0px; border-bottom-right-radius: 0px; border-bottom-left-radius: 0px; word-wrap: normal; background-position: initial initial; background-repeat: initial initial;">private void loadImageThumbnailRequest()   
    // setup Glide request without the into() method
    DrawableRequestBuilder<String> thumbnailRequest = Glide
        <span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.with</span>( context )
        <span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.load</span>( R<span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.drawable</span><span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.pic</span>)<span class="hljs-comment" style="color: rgb(136, 0, 0); box-sizing: border-box;">;</span>
    // pass the request as a a parameter to the thumbnail request
    Glide
        <span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.with</span>( context )
        <span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.load</span>( UsageExampleGifAndVideos<span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.gifUrl</span> )
        <span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.thumbnail</span>( thumbnailRequest )
        <span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.into</span>( imageView3 )<span class="hljs-comment" style="color: rgb(136, 0, 0); b
