i’m trying to develop the given UI in android, there is a ListView and on top of it a button is visible , listView’s height is Fill_PARENT and button is fix at it’s position.
How to add a view above of a view? or any idea about creating this layout using XML or customizedView.

I think from what i understand in your question it seems like you are looking for
FrameLayout. So there is a list view and top of it is a button. Right? Try this.
