Question

I’m used to the fact that items of listview without any problem (even with complicated layout) handle onpress events (some actions that makes it pressed and unpressed). But now I want the same from LinearLayout – if you press anyway on layout, all descendants should get onpress events.

This is the part of my fragment layout, which should be highlighted onpress event.

<LinearLayout
            android:id="@+id/ll_about_fragment_feedback"
            android:gravity="center_vertical"
            android:layout_height="54dp"
            android:background="@drawable/about_item_bkg"
            android:layout_width="match_parent">

        <ImageView
                android:layout_height="wrap_content"
                android:background="@drawable/about_item_feedback_icon"
                android:layout_width="wrap_content"
                android:layout_marginLeft="11dp"/>

        <TextView
                android:layout_height="wrap_content"
                android:layout_width="wrap_content"
                android:text="@string/about_fragment_feedback"
                android:layout_marginLeft="14dp"
                android:textSize="16dp"
                android:textColor="@drawable/about_item_textcolor"/>

</LinearLayout>

Background of root layout changes onpress, but textcolor of descendants don’t. Looks like they don’t get event from root.

So, can you help?

UPDATE: LinearLayout ll_about_fragment_feedback has bound OnClickListener and there is everything fine with selecrors

If you want a Selector to apply to all views under your LinearLayout then you just need to add android:duplicateParentState="true" to all of the child views.

<LinearLayout
    android:id="@+id/ll_about_fragment_feedback"
    android:layout_width="match_parent"
    android:layout_height="54dp"
    android:background="@drawable/about_item_bkg"
    android:gravity="center_vertical" >

    <ImageView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginLeft="11dp"
        android:background="@drawable/about_item_feedback_icon"
        android:duplicateParentState="true" />

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginLeft="14dp"
        android:duplicateParentState="true"
        android:text="@string/about_fragment_feedback"
        android:textColor="@drawable/about_item_textcolor"
        android:textSize="16dp" />

</LinearLayout>
