这是我正在使用的结构
<FrameLayout android:layout_width="fill_parent"
android:layout_height="fill_parent"
xmlns:android="http://schemas.android.com/apk/res/android">
<AbsoluteLayout android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="@+id/abs_layout">
<ImageView />
<ImageView />
</AbsoluteLayout>
<ImageView android:id="@+id/icon"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/icon"/>
</FrameLayout>
上面的结构工作正常,但是当我使用下面的结构时会出错
<FrameLayout android:layout_width="fill_parent"
android:layout_height="fill_parent"
xmlns:android="http://schemas.android.com/apk/res/android">
<ImageView android:id="@+id/icon"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/icon"/>
<AbsoluteLayout android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="@+id/abs_layout">
<ImageView />
<ImageView />
</AbsoluteLayout>
</FrameLayout>
