[안드로이드] 볼륨 롱키 인식하기

타이머를 써야 하나 flag를 써야 하나 고민도 해봤는데,

안드로이드에서 volume long key 인식하는 방법입니다.

@Override public boolean onKeyLongPress(int keycode, KeyEvent event){ if(keycode == KeyEvent.KEYCODE_VOLUME_UP || keycode == KeyEvent.KEYCODE_VOLUME_DOWN) { Log.d(TAG, "Long press KEYCODE_VOLUME_UP"); return true; } return super.onKeyLongPress(keycode, event); } @Override public boolean onKeyDown(int keycode, KeyEvent event) { if( keycode == KeyEvent.KEYCODE_VOLUME_UP || keycode == KeyEvent.KEYCODE_VOLUME_DOWN) { event.startTracking(); return true; } return super.onKeyDown(keycode, event); } @Override public boolean onKeyUp(int keyCode, KeyEvent event) { if((event.getFlags() & KeyEvent.FLAG_CANCELED_LONG_PRESS) == 0){ if(keyCode == KeyEvent.KEYCODE_VOLUME_UP){ Log.i(TAG, "Short press KEYCODE_VOLUME_UP"); return true; } else if(keyCode == KeyEvent.KEYCODE_VOLUME_DOWN){ Log.i(TAG, "Short press KEYCODE_VOLUME_DOWN"); return true; } } return super.onKeyUp(keyCode, event); }
