Can I increase a buttons onclick-area programmatically?

Question

Sometimes I have a button in my UI that it is so small that it is difficult to click. My solution so far has been to add a transparent border around the button in photoshop. Just increasing the padding on the button does not work, since this will also stretch the image. Since it is kind of a fuss to open photoshop each time I want to change the clickable surface, is there any way to do this programmatically? I have tried placing a framelayout behind the button and make it clickable, but then the button wont change appearance on touch as it should. Ofcourse I could also add a ontouchlistener on the framelayout which changes the buttons appearance, but then it quite some code if I have several of those buttons.

Cheers,

Answer 1

Maybe you could do so by looking at the X and Y coordinates of the MotionEvent passed into onTouchEvent ?

Answer 2

I think your solution is the best one available at the moment, if you don't want to go deep into some android stuff and intercept all the motionEvent and TouchEvents yourself and then you also would need to trigger the pressed view of the button yourself etc.

Just create a nine patch image with a stretchable transparent border. In that way you can change the size of the image without the need to change the image itself and your button will grow or shrink without the actual displayed background changing.
