Changing an ImageResource (drawable) programmatically

Question

I am currently using the @android:drawable/presence_online as the srcCompat for a ImageView.

I would like to change it programmatically to @android:drawable/presence_offline.

I tried the code below but it didn't work.

    final ImageView imgPresence = (ImageView) findViewById(R.id.imgPresence);
    imgPresence.setImageResource(R.drawable.presence_offline);

Any ideas?

You missed android in the resource id.

Instead of

imgPresence.setImageResource(R.drawable.presence_offline);

use this:

imgPresence.setImageResource(android.R.drawable.presence_offline);
