"android.view.View cannot be cast to android.view.ViewGroup" exception
提问by Boda Taljo
I am working on an android application and I added a xml layout file that should be a fragment later:
我正在开发一个 android 应用程序，我添加了一个 xml 布局文件，它应该是一个片段：
<?xml version="1.0" encoding="utf-8"?>
<View xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<ImageView
android:id="@+id/imgTile"
android:src="@drawable/tile_background"
android:contentDescription="@string/CD_TILE_BACKGROUND_IMAGE"
android:layout_width="match_parent"
android:layout_height="match_parent">
</ImageView>
</View>
When I try to move back to the graphical layout in Eclipse, I get this exception in the error log:
当我尝试移回 中的图形布局时Eclipse，我在错误日志中收到此异常：

I think you should use
我认为你应该使用
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<ImageView
android:id="@+id/imgTile"
android:src="@drawable/tile_background"
android:contentDescription="@string/CD_TILE_BACKGROUND_IMAGE"
android:layout_width="match_parent"
android:layout_height="match_parent">
</ImageView>
</LinearLayout >
as View does not have any function like add(other_view) you can add a view in ViewGorup ....
因为 View 没有像 add(other_view) 这样的函数，你可以在 ViewGorup 中添加一个视图 ....

I know i am late to the party, but just in case some is banging his head for same problem, here is one possible solution that worked for me when i was trying to add zoom functionality in my pager adapter images. Info: this is not the exact answer, but a possible solution for those who are facing the same problem. I am posting this because i didn't fount this solution approach anywhere in stackOverflow
我知道我参加聚会迟到了，但以防万一有人因为同样的问题撞到他的头，这里有一个可能的解决方案，当我尝试在我的寻呼机适配器图像中添加缩放功能时，它对我有用。信息：这不是确切的答案，而是针对面临相同问题的人的可能解决方案。我发布这个是因为我没有在 stackOverflow 的任何地方找到这个解决方案
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<ImageView
android:id="@+id/head_image"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:scaleType="centerCrop"
android:src="@drawable/head_image" />
</RelativeLayout>
In the above code, just Replace <ImageViewwith <com.yourPackage.TouchImageView.
在上面的代码中，只需替换<ImageView为<com.yourPackage.TouchImageView.
TouchImageView(or any other class) is a custom class (you need to make)which should extend android.support.v7.widget.AppCompatImageView
TouchImageView（或任何其他类）是一个自定义类（您需要制作），它应该扩展android.support.v7.widget.AppCompatImageView
