How to change the z-order of window added via Wind

问题:

Is it possible to specify the z-order of each window ? in the image below each editText are in their own window added via WindowManager. as you can see i have a z-order problem

like you see on the picture, the last window added seam to take the higher z-order. So the only way out i find to put a window at the higher z-order is to remove the view from windowManager and then immediately add it again. It's not very optimal solution, because visually the view disappear and reappear on the screen
