How do I programmatically change the ImageButton src target when a condition is met?

Question

I have a school project where I am trying to get a flashlight app going. For the on/off ImageButton, I want to have 4 custom images.

Is it a requirement that it has to be imageResource? You can try using backgroundResource instead.

ImageButton flashButtonOn = (ImageButton) findViewById(R.id.flashButtonOn);
flashButtonOn.setBackgroundResource(R.drawable.on_selector);

Or try

flashButtonOn.setImageResource(R.drawable.replacementGraphic);
