Testing for Resources such as Drawables and Background

Issue

I need to see if there is a way where I can test for what background a button has. For example, here is my pseudo code:

if (button background is `R.drawable.black`) {
  button.setBackground(to R.drawable.white)
}

Is there a way that this if statement can be done? I know how to SET backgrounds, just curious on the test portion.

Solution

In your case, I believe that tags would be useful. Try this:

//When you set the button:
btn.setBackgroundResource(R.drawable.black);
btn.setTag(R.drawable.black);


//When you re-set the button:
if(btn.getTag().equals(R.drawable.black)) {
    btn.setBackgroundResource(R.drawable.white);
    btn.setTag(R.drawable.white);
}
