Get All views higher in z index than given View?

Question

I have to find out all the views higher in z-index ( could be overlapping ) than given view public List<View> getViewsHigherInZIndex(View givenView) { //return all views higher in z index than givenView } One of the approach I thought involves finding Parent View of given View and then recursively finding all the elements. Even though I have all the View elements, how can I determine z-index of the child views. How can I compare them to find out if they are overlapping. I can get Rectangle bounds and see if they are intersecting but that doesn't give z-order.

Answer 1

You could use a recursive DFS to walk the View hierarchy with ViewGroup.getChildAt(), then use View.getZ() to compare Z values.
