Im am having a parent layout RelativeLayout inside ScrollView which contains several child layouts and a child layout (i.e preview_wrapper) at end of RelativeLayout which fills the it with match_parent LayoutParam and contains a Background with alpha color and its clickable and focusable is set to true so that no view inside the parent layout is clickable. but it not working for me i am unable to see the last child fill the parent layout bring to front. however when I remove ScrollView its working perfect.. but i need to bring it inside ScrollView as I make the preview_wrapper outside the ScrollView i am unable to scroll the layout.

<ScrollView> <RelativeLayout> <LinearLayout> </LinearLayout> <!-- the layout I want to bring in front of above linear layout and cover its parent --> <RelativeLayout android:layout_width="match_parent" android:layout_height="match_parent" android:background="@color/alpha_white" android:clickable="true" android:focusable="true" android:id="@+id/preview_wrapper" ></RelativeLayout> </RelativeLayout> </ScrollView> XML:
