HID 标准输入在手机上的优缺点

HID 标准输入手柄的缺点

• 会操作 手机上的home建、返回键、会操作选择；需要对onKeyDown 事件进行重写，最好重写onGenericMotionEvent，会操作摇杆，和上下左右，压力值按键

 @Override
    public boolean onGenericMotionEvent(MotionEvent arg15) {
        return true;
    }

    @Override
    public boolean onKeyDown(int keyCode, KeyEvent event) {
        return CommonUtils.isConfirmKey(keyCode) || super.onKeyDown(keyCode, event);
    }

 public static boolean isConfirmKey(int keyCode) {
        switch (keyCode) {
            case KeyEvent.KEYCODE_BUTTON_A:
            case KeyEvent.KEYCODE_BUTTON_B:
            case KeyEvent.KEYCODE_BUTTON_C:
            case KeyEvent.KEYCODE_BUTTON_X:
            case KeyEvent.KEYCODE_BUTTON_Y:
            case KeyEvent.KEYCODE_BUTTON_Z:
            case KeyEvent.KEYCODE_BUTTON_L1:
            case KeyEvent.KEYCODE_BUTTON_R1:
            case KeyEvent.KEYCODE_BUTTON_L2:
            case KeyEvent.KEYCODE_BUTTON_R2:
            case KeyEvent.KEYCODE_BUTTON_THUMBL:
            case KeyEvent.KEYCODE_BUTTON_THUMBR:
            case KeyEvent.KEYCODE_BUTTON_START:
            case KeyEvent.KEYCODE_BUTTON_SELECT:
            case KeyEvent.KEYCODE_BUTTON_MODE:
            case KeyEvent.KEYCODE_BUTTON_1:
            case KeyEvent.KEYCODE_BUTTON_2:
            case KeyEvent.KEYCODE_BUTTON_3:
            case KeyEvent.KEYCODE_BUTTON_4:
            case KeyEvent.KEYCODE_BUTTON_5:
            case KeyEvent.KEYCODE_BUTTON_6:
            case KeyEvent.KEYCODE_BUTTON_7:
            case KeyEvent.KEYCODE_BUTTON_8:
            case KeyEvent.KEYCODE_BUTTON_9:
            case KeyEvent.KEYCODE_BUTTON_10:
            case KeyEvent.KEYCODE_BUTTON_11:
            case KeyEvent.KEYCODE_BUTTON_12:
            case KeyEvent.KEYCODE_BUTTON_13:
            case KeyEvent.KEYCODE_BUTTON_14:
            case KeyEvent.KEYCODE_BUTTON_15:
            case KeyEvent.KEYCODE_BUTTON_16:
            case KeyEvent.KEYCODE_DPAD_CENTER:
            case KeyEvent.KEYCODE_ENTER:
            case KeyEvent.KEYCODE_SPACE:
            case KeyEvent.KEYCODE_NUMPAD_ENTER:
                return true;
            default:
                return false;
        }
    }

HID模式的鼠标键盘缺点

• HID模式的鼠标，可唤出手机上的鼠标指示键，但是游戏中鼠标指示键的点击是不给予识别的，所以在游戏中操作不了，
