Propagation of touch events

Question

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?

try to create custom ListView, override dispatchTouchEvent and invoke super method there but return true to prevent propagating. — Flavio, May 16 '11 at 12:26

You can set android:duplicateParentState="false" on your textview

Whether a view has pressed state does not depend on duplicateParentState. – Randy Sugianto 'Yuku' Nov 23 '11 at 06:21
