Simple three steps:

1. Create a runtime broadcast receiver with your own action(Ex: UPDATED_TEXT_PREFERENCES).
2. Register/unregister for broadcast in onStart() and onStop()
3. On your USER_ACTIVE onReciever(). send a broadcast with the own action you have created(Ex: UPDATED_TEXT_PREFERENCES)
4. On your activity onReceive you can update your textview.
