“android.view.View不能被转换为android.view.ViewGroup”异常

前端之家收集整理的这篇文章主要介绍了“android.view.View不能被转换为android.view.ViewGroup”异常前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
我正在开发一个 Android应用程序,我添加了一个应该是片段的xml布局文件
<?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>

当我尝试回到Eclipse中的图形布局时,我在错误日志中收到这个异常:

有谁可以帮我这个例外吗?

解决方法

我想你应该使用
<?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 >

因为View没有任何类似add(other_view)的功能,您可以在ViewGorup中添加视图….
