How to Remove Background Color of Button to get Default Background in Android

Question

I am Working on a Test Application in which every question is presented with Four options [those options are via Button]. When a User clicks a button and his answer is correct then background of that button Turns Green, and if his answer is incorrect it turns Red. What i want to do is Reset the Button Background on Next Question.

After Searching a lot of People have asked the same Question and Accepted the answer as

  btnChoiceB.setBackgroundColor(0x00000000);

But the problem is, it turns the Whole Button Transparent, which is not my requirement. I Just want the default color Back.

Do Not Suggest

btnChoiceB.setBackgroundColor(null);

as it does not work.

This is What i want Back.

UPDATE/ANSWERED

As Suggested by quick learner,

btnChoiceB.setBackgroundResource(android.R.drawable.btn_default);

worked pretty cleanly.

Answer 1

Try this

btnChoiceB.setBackgroundResource(android.R.drawable.btn_default);
