安卓红外远程覆盖电源键

Question

如何为有根的安卓设备覆盖红外遥控器的电源键？我尝试了以下方法

         case KeyEvent.KEYCODE_STB_POWER:
            Toast.makeText(this, "KEYCODE_STB_POWER key pressed",
                    Toast.LENGTH_SHORT).show();
            return true;
        case KeyEvent.KEYCODE_AVR_POWER:
            Toast.makeText(this, "KEYCODE_AVR_POWER key pressed",
                    Toast.LENGTH_SHORT).show();
            return true;
        case KeyEvent.KEYCODE_TV_POWER:
            Toast.makeText(this, "KEYCODE_AVR_POWER key pressed",
                    Toast.LENGTH_SHORT).show();
            return true;
        case KeyEvent.KEYCODE_POWER:
            Toast.makeText(this, "KEYCODE_POWER key pressed",
                    Toast.LENGTH_SHORT).show();
            return true;

但以上这些都不起作用。我错过了什么吗？

尝试记录密钥，以便获得要处理的实际 KeyEvent。例如：

@Override
public boolean onKeyUp(int keyCode, KeyEvent event) {
    Log.d("keycode", "" + keyCode);
(...)
}
