I'll need to implement a UI that reflects the layout of a real object. Below is the layout that the client wants. Each black block is a button, so it need a custom drawable, listeners, states, etc.

I'd like to use a custom implementation of the Button widget, but as far as I know they only accept rectangular touch targets and laying them out could be tricky.

enter image description here

What would you use to achieve this layout?
Please note: the 2 central button should be a semicircle cutted in half (with some padding between the 2), not this strange shieldy shape, I'm just not that good with Photoshop.

EDIT: As suggested in this question I could use a TouchListener on the layout and fake a click on the right button. The main problem with this solution is that I'll need to know the bounds of the drawable, not the rectangular ones of the button's bounding box (that is always rectangular). How could I do that?

  • @Foxinsocks I'll try with the overlaying touch listener, I'll just need to figure out how to understand the bounds of the buttons. Commented Apr 14, 2014 at 9:52
  • I'll try with a RelativeLayout containing some TextViews or ImageViews (which are clickable controls). Relatively positioned over the background image. It does really no matter, if they are "square" controls. You typically touch the clickable areas inside, not on the corners or on the sides. So, the "square" approximation is good enough.
