keypress event in android

Question

Answer 1

here is the whole list of keycodes on android. Don't use the int. Use the static value of KeyEvent. http://developer.android.com/reference/android/view/KeyEvent.html

in the activity you can overwrite one of the following (or more if you like)

boolean onKeyDown(int keyCode, KeyEvent event)
boolean onKeyLongPress(int keyCode, KeyEvent event)
boolean onKeyMultiple(int keyCode, int repeatCount, KeyEvent event)
boolean onKeyUp(int keyCode, KeyEvent event)

and in there you can just do:

if (event.getKeyCode() == KeyEvent.KEYCODE_A) {
    // do whatever you want.
}

instead of KeyEvent.KEYCODE_A use whatever you want. For example KeyEvent.KEYCODE_BACK for the back key.
