If you need the exact functionality of the back button in your custom button  why not just call yourActivity onBackPressed   that way if you override the functionality of the backbutton your custom button will behave the same

If you are inside the fragment then you write the following line of code inside your on click listener  getActivity   onBackPressed     this works perfectly for me

You should use finish   when the user clicks on the button in order to go to the previous activity   Button backButton    Button this findViewById R id back   backButton setOnClickListener new OnClickListener        Override   public void onClick View v        finish              Alternatively  if you really need to  you can try to trigger your own back key press   this dispatchKeyEvent new KeyEvent KeyEvent ACTION DOWN  KeyEvent KEYCODE BACK    this dispatchKeyEvent new KeyEvent KeyEvent ACTION UP  KeyEvent KEYCODE BACK      Execute both of these
