在Android

Question

我有一个示例游戏并启用了immersive mode，但最后的正确按钮效果不佳。当我启用immersive mode时Touch Input工作，因为它将是带有软件按钮的屏幕，尽管它们根本不可见。

如果我关闭Touch Input，软件按钮所在的右上角的每个immersive mode将无效。

我不知道如何解决这个问题。我附上了源代码here：

这是我的主要游戏类：

 public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);


        // Immersive Mode
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                WindowManager.LayoutParams.FLAG_FULLSCREEN);


      getWindow().getDecorView().setSystemUiVisibility(
                                                                 View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                                                                 | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                                                                 | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                                                                 | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
                                                                 | View.SYSTEM_UI_FLAG_FULLSCREEN
                                                                 | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY);


        boolean isPortrait = getResources().getConfiguration().orientation == Configuration.ORIENTATION_PORTRAIT;
        int frameBufferWidth = isPortrait ? 480: 800;
        int frameBufferHeight = isPortrait ? 800: 480;
        Bitmap frameBuffer = Bitmap.createBitmap(frameBufferWidth,
                frameBufferHeight, Config.RGB_565);

        float scaleX = (float) frameBufferWidth
                / getWindowManager().getDefaultDisplay().getWidth();
        float scaleY = (float) frameBufferHeight
                / getWindowManager().getDefaultDisplay().getHeight();

        renderView = new AndroidFastRenderView(this, frameBuffer);
        graphics = new AndroidGraphics(getAssets(), frameBuffer);
        fileIO = new AndroidFileIO(this);
        audio = new AndroidAudio(this);
        input = new AndroidInput(this, renderView, scaleX, scaleY); <- INPUT
        screen = getInitScreen();
        setContentView(renderView);

Android Input class将初始化此类
