【中文标题】如何通过相机或图库动态添加图像？【英文标题】：How can I Add images dynamically through Camera or Gallery? 【发布时间】：2017-08-25 05:49:08 【问题描述】：我正在制作一个 android 应用程序，允许用户通过相机单击图片或通过图库添加图像。
图像视图中只允许添加 5 张图像。我如何在运行时在活动中动态添加图像视图。
如何删除和重新定位活动中存在的图像。
因为有 5 张图片，所以当我删除第 2 张图片时，第 3、第 4 和第 5 张图片应该重新定位到第 2、第 3 和第 4 张图片，它应该允许我添加第 5 张图片。
任何人都可以帮助我提供源代码。
这是我的代码：

private static final int PICK_PICTURE_SECOND_IMAGE = 106;

【问题讨论】：
请输入代码。代码 请检查编辑...抱歉耽搁了 请而不是点击向下箭头...尝试理解我的问题并帮助如果你能...如果你不能不向下箭头我的问题 如果我是对的，你想动态创建图像视图。 是 .... 我想动态创建 Imageview ... 应该只有 5 个 imageview ,,.. 并且想要添加删除功能 ... 如果删除了位置应该更改.. .. 【参考方案1】：您可以像这样动态创建 ImageView：
container = (LinearLayout)findViewById(R.id.container);
for (int j = 0; j < 4; j++)
Intent takePicture = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(takePicture, CAMERA_REQUEST);
ImageView newimageview = new ImageView(MainActivity.this);
newimageview.setBackgroundResource(R.drawable.panama_app_logo);
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(50,50);
newimageview.setLayoutParams(params);
container.addView(newimageview);
【讨论】：
谢谢@DK Thakur ...我会尝试使用这种方法解决 您可以使用 view.removeViewAt(index); 删除 imageview；RelativeLayout dynamicRelative = (RelativeLayout)findViewById(R.id.dynamicRelative);``int numberofimages = 4; for (int j = 0; j < numberofimages; j++) Intent takePicture = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); startActivityForResult(takePicture, CAMERA_REQUEST); newimageview = new ImageView(MainActivity.this); dynamicRelative.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,ViewGroup.LayoutParams.WRAP_CONTENT));newimageview.setMaxHeight(50);newimageview.setMaxWidth(50); `dynamicRelative.addView(newimageview);
@DK Thakur 你能检查一下这段代码有什么问题吗……它只显示一张图片
它正在添加所有但只显示一个，因为您使用的是RelativeLayout。如果您使用LinearLayout，您可以看到添加到视图中的所有图像。以上是关于如何通过相机或图库动态添加图像？的主要内容，如果未能解决你的问题，请参考以下文章
