使用dispatchKeyEvent onkeyevent return true没得按键音问题

因为返回了true所以如果自己不发出按键的声音的话,就没得声音发出了,因为键值已经被你拦截了,不会往下分发.

public boolean dispatchKeyEvent(KeyEvent event) {
		if (event.getAction() == KeyEvent.ACTION_UP) {
			return super.dispatchKeyEvent(event);
		}
		if (event.getKeyCode() == KeyEvent.KEYCODE_DPAD_DOWN) {
			if (moveFocus(true)) {
				playClickVolumn();
				return true;
			} else {
				return false;
			}
		} else if (event.getKeyCode() == KeyEvent.KEYCODE_DPAD_UP) {
			if (moveFocus(false)) {
				playClickVolumn();
				return true;
			} else {
				return false;
			}
		}
		return super.dispatchKeyEvent(event);
	}

	private void playClickVolumn() {
		final AudioManager audioManager = (AudioManager) mContext
				.getSystemService(Context.AUDIO_SERVICE);
		audioManager.playSoundEffect(AudioManager.FX_KEY_CLICK);
	}
