触摸事件的传播
我有一些ListView。每个列表元素都是使用如下所示的布局构建的：
<SomeRootLayout android:background="@layout/some_other_selector">
<TextView android:background="@layout/some_selector"/>
<TextView android:background="@layout/some_selector"/>
<ImageView/>
</SomeRootLayout>
some_selector.xml 如下所示：
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:state_pressed="true" android:drawable="@drawable/ic_btn_stop_pressed" />
<item android:drawable="@drawable/ic_btn_stop_default" />
</selector>
现在，当用户按下整行时，每个 TextView 也会被按下（不是真正按下 -不会生成 onClick 事件，但是 TextView 根据其选择器更改其背景）。有什么想法告诉系统不要将触摸事件从父视图传播到子视图吗？
I've got some ListView. Each list element is constructed using layout looking like this:
<SomeRootLayout android:background="@layout/some_other_selector">
<TextView android:background="@layout/some_selector"/>
<TextView android:background="@layout/some_selector"/>
<ImageView/>
</SomeRootLayout>
The some_selector.xml is looking like this:
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:state_pressed="true" android:drawable="@drawable/ic_btn_stop_pressed" />
<item android:drawable="@drawable/ic_btn_stop_default" />
</selector>
Now, when the user press the entire row, the each TextView is being pressed as well (not really pressed - no onClick events are generated, however TextViews change its background according to their selectors). Any ideas to tell system NOT to propagate touch events from parent to child views?

您可以在 textview 上设置
android:duplicateParentState="false"You can set
android:duplicateParentState="false"on your textview
