Making an ImageButton - without button border nor highlight

I have two png-images for the pressed and released state of a button. I'd like to build a button that accomplishes the following:

  1. Has no background/border (only those two images visible)
  2. Does not highlight with a blue rectangle when clicked (only by cycling through those images)
  3. Does not get activated, when the user clicks on a transparent part of the image.

Red button with explamation mark, has the form of a stop sign

As you can see, the button is not rectangular, so the last point mentioned above might be tricky.

I already tried to use an ImageButton and managed to meet point 1, but I failed at point 2.
Is there another View I can use, that does the work for me? If not, could you hint me what techniques I should look into to solve this?

If you use setBackground = "#0xxx"; on button in xml file the borders will desappear. Basically making it transparent using alpha

android:setBackground = "#0AAA"

[Edit] for third part- follow this https://stackoverflow.com/a/8086317/3811198 in short

Use a TouchListener instead of ClickListener

Inside the listener, if the event is MotionEvent.ACTION_DOWN, get the touch coordinates

Check the image's pixel at the coordinates you obtained earlier; if the pixel is not transparent, consider the button was clicked, otherwise ignore the event.

Just use ImageView

One image set as background, second as src. And it resolve all your problems
