title: How to use android button png as a button in my app
body: <p>I have a two png files. The button and it's "pressed state".</p>
  
  <p>1)How do I replace the default android button with my png(the text of the button is included in the png, there's no need to define a textView over the image. </p>
  
  <p>2) And also how do I implement the "onPress" state png???. </p>
  
  <p>I've been 3 days searching for answers but there's little to no information on this subject in particular. I just found the rotate animations an all of that, but nothing on how to replace a default button with a drawable and then use another png file when the user press the button</p>
