There is no need to create a thread for this, or animations.

The solution is really simple: use Handler.postDelayed() or Handler.sendMessageDelayed():

For a robust implementation, be sure to remove any pending messages at least by Activity.onDestroy(). (Or if you are posting them in Activity.onStart(), remove them in Activity.onStop(); if posting in Activity.onResume(), remove in Activity.onPause().)
