Answer 1

1. The most convenient way is to create the shape as image, and put it to the drawable directory. Then you can set it as background to your pointer.
2. You should use FrameLayout. In your XML, put the pointer shape view to the last child of the FrameLayout, so it will be "above" the others, in the Z axis. Then in code, set the X and Y coordinates of the pointer shape view to point to another view.

I hope it helps!
