Answer 4

You can calculate it with the position and the width and height of the View.

Position: Use View.getLocationOnScreen() and/or getLocationInWindow().
Width/height: Use View.getWidth() and View.getHeight().

Answer 5

The view that is defined first in your xml layout will be drawn first. The next view will be drawn on top of the previous view if there is any.

By that principle, you can ask your frame/relative layout to check the ordering where the child views are ordered:

int indexV1 = layout.indexOfChild(v1);
int indexV2 = layout.indexOfChild(v2);
if(indexV1 < indexV2) {
    // v1 is below v2
}
