How do I process the enter key in EditText?

edittext.setOnKeyListener(new View.OnKeyListener() {
            @Override
            public boolean onKey(View v, int keyCode, KeyEvent event) {
                //Enter key Action
                if ((event.getAction() == KeyEvent.ACTION_DOWN) && (keyCode == KeyEvent.KEYCODE_ENTER)) {
    //Press Enter to process 
    return true;
                }
                return false;
            }
        });
