1211 - 华为荣耀虚拟键盘

3.16 中给出了解决方案：

    protected void hideVirtualButton() {
        // if (showVirtualButton) {
        //     return;
        // }

        if (Build.VERSION.SDK_INT >= 19) {
            // use reflection to remove dependence of API level

            Class viewClass = View.class;

            try {
                final int SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION = Cocos2dxReflectionHelper.<Integer>getConstantValue(viewClass, "SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION");
                final int SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN = Cocos2dxReflectionHelper.<Integer>getConstantValue(viewClass, "SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN");
                final int SYSTEM_UI_FLAG_HIDE_NAVIGATION = Cocos2dxReflectionHelper.<Integer>getConstantValue(viewClass, "SYSTEM_UI_FLAG_HIDE_NAVIGATION");
                final int SYSTEM_UI_FLAG_FULLSCREEN = Cocos2dxReflectionHelper.<Integer>getConstantValue(viewClass, "SYSTEM_UI_FLAG_FULLSCREEN");
                final int SYSTEM_UI_FLAG_IMMERSIVE_STICKY = Cocos2dxReflectionHelper.<Integer>getConstantValue(viewClass, "SYSTEM_UI_FLAG_IMMERSIVE_STICKY");
                final int SYSTEM_UI_FLAG_LAYOUT_STABLE = Cocos2dxReflectionHelper.<Integer>getConstantValue(viewClass, "SYSTEM_UI_FLAG_LAYOUT_STABLE");

                // getWindow().getDecorView().setSystemUiVisibility();
                final Object[] parameters = new Object[]{SYSTEM_UI_FLAG_LAYOUT_STABLE
                        | SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                        | SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                        | SYSTEM_UI_FLAG_HIDE_NAVIGATION // hide nav bar
                        | SYSTEM_UI_FLAG_FULLSCREEN // hide status bar
                        | SYSTEM_UI_FLAG_IMMERSIVE_STICKY};
                Cocos2dxReflectionHelper.<Void>invokeInstanceMethod(getWindow().getDecorView(),
                        "setSystemUiVisibility",
                        new Class[]{Integer.TYPE},
                        parameters);
            } catch (NullPointerException e) {
                Log.e(TAG, "hideVirtualButton", e);
            }
        }
    }

放到老版本中去好了。
