How to modify the default button state in Android without affecting the pressed and selected states?

Question

I am trying to remove an ImageButton\'s background in only the default state. I\'d like the pressed and selected states to behave as usual so that they look correct on diffe

Answer 1

StateListDrawable replace = new StateListDrawable();

Drawable old = getBackground();
replace.addState(FOCUSED_STATE_SET, old);
replace.addState(SELECTED_STATE_SET, old);
replace.addState(PRESSED_STATE_SET, old);

replace.addState(StateSet.WILD_CARD, new ColorDrawable(Color.TRANSPARENT));

if (Build.VERSION.SDK_INT >= 16) {
    setBackground(replace);
} else {
    setBackgroundDrawable(replace);
}
