You need to be more precise.
In the image in your post there is no overlapping?
What exactly is the problem ?
ImageView1 has the vertical anchors set to both, this means that the top value is defined and the bottom value is equal the given distance to the bootom edge. Depending on the screen height the ImageView1 height can change.
Button4 has the Top anchor.
If on a device with screen higher than the layout height definition there could be an overlapping between ImageView1 and Button4.
