###Notes

• Currently the last key code is KEYCODE_SYSTEM_NAVIGATION_RIGHT, which is 283 (but check the source code to make sure this is still true). So you could loop through them like this:

    for (int keyCode = 0; keyCode <= 287; keyCode++) {
  
    }
  

• Most input to EditText (or a custom view that accepts keyboard input) from an Input Method Editor (IME) is done using an Input Connection, so many key codes are not sent at all in this case. See this answer.

below are the key codes::: LINK

KEYCODE_POUND for #

KEYCODE_STAR for *

and you can get the key number of the event by using event.getNumber() like below.

    @Override
    public boolean onKeyDown(int keyCode, KeyEvent event)  {

        Log.d("::"+keyCode,"::"+event.getNumber());
            return super.onKeyDown(keyCode, event);
    }
