Question

how can I get the previous view(TextView) of the SlideButton view, and the next view of the SlideButton view.

The SlideButton view with the id “remotelight”. I can get the SlideButton view with the method “findViewById”.
so after I get the SlideButton View, how can I get the previous view and the next view ,without the help of “findViewById” method.

thanks so much.

below is a part of layout xml:

<TableRow
    android:id="@+id/tableRow1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" >

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="" />

    <com.ivn.SlideButton
        android:id="@+id/remotelight"
        android:layout_width="100dp"
        android:layout_height="50dp" />


    <TextView
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="" />

</TableRow>

You can use the ViewGroup instance that’s acting as a container for your widgets to do this.

See getChildAt(int) and
indexOfChild(View)

So getChildAt(indexOfChild(v)+1) will get you the next view.

So something like

 ViewGroup container = (ViewGroup) findViewbyID(R.tableRow1);
 View slideBtn = findViewbyID(R.remoteLight);
 View nextView = container.getChildAt(container.indexOfChild(slideBtn)+1);

You should add checks for overflow and that the next view is of the type that you do in fact want.
