dispatchKeyEvent calling method twice

问题:

I've implemented dispatchKeyEvent in my activity to listen to the Enter key being pressed. The problem is that when i click enter,it calls my method twice ? How can i fix this ? Thanks,have a nice day !

@Override public boolean dispatchKeyEvent(KeyEvent e) { if (e.getKeyCode() == KeyEvent.KEYCODE_ENTER) {                enter();         return true;     }     return super.dispatchKeyEvent(e); };

Fixed it,done this : At first i was doing ACTION_DOWN but that was triggering an older problem of mine.

 @Override public boolean dispatchKeyEvent(KeyEvent event) {     if (event.getKeyCode() == KeyEvent.KEYCODE_ENTER) {         if (event.getAction() == KeyEvent.ACTION_UP){           enter();              return true;     }}     return super.dispatchKeyEvent(event); };
