Android ImageButton - determine what resource is currently set

Question

Is there a way I can find what resource a particular ImageButton is set to, at any given time?

For eg: I have an ImageButton that I set to R.drawable.btn_on

Answer 1

I don't know how to access the resource directly, but for what you try to achieve, wouldn't it suffice to just get the state?

    ImageButton btn = (ImageButton) findViewById(R.id.btn);

    int [] states = btn.getDrawableState();
    for (int i : states) {
        if (i == android.R.attr.state_pressed) {
            Log.v("btn", "Button in pressed state");
        }
    }
