篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了在app的活动的imageview中准确加载图像相关的知识，希望对你有一定的参考价值。
我正在尝试实现一个应用程序，其中在创建活动时在图像视图中加载大量图像 - 在滚动视图中正好有24个图像视图对齐。当我用24 imageview作为启动器活动本身启动该活动时 - 它工作正常..但是，当我在欢迎屏幕后使用该活动作为第二个活动时它崩溃并说 - >

这里是第15行，它在“onCreate” - >上显示错误-i.e
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main); //line no 15 in my code(indicated in the logcat)
}
答案
在你的清单中使用它：
<application
android:allowBackup="true"
android:hardwareAccelerated="false"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:largeHeap="true"
android:supportsRtl="true"
android:theme="@style/AppTheme">
另一答案
添加清单文件android：hardwareAccelerated =“false”，android：largeHeap =“true”它适用于某些环境。
<application
android:allowBackup="true"
android:hardwareAccelerated="false"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:largeHeap="true"
android:supportsRtl="true"
android:theme="@style/AppTheme">
另一答案
使用像Glide和Picasso这样的图像加载库。对于Glide：
public static void loadToGlide(Context context, ImageView imageView, Object o) {
Glide.with(context)
.asBitmap()
.apply(new RequestOptions()
.centerCrop())
.transition(new BitmapTransitionOptions()
.crossFade())
.load(o)
.into(imageView);
}
致电：
loadToGlide(context, yourImageView, R.drawable.yourImage);
他们将为您处理一切，尤其是OutOfMemoryError。
另一答案
您可以使用recylerview而不是多个imagviews，并且可以使用volley imageloader或glide来加载seamlessely。
