Short press the button to run the method onClick(..) in setOnClickListener(..). Long press the button to execute callback code in the onContextItemSelected(..) method. See a toast popup for both and a TextView message from the last action remains. The registerForContextMenu(button1) produces a call to onCreateContextMenu(..) to define the Context Menu.
