隐藏特定时间的状态栏和标题栏

Question

我想在特定时间在同一布局中隐藏状态栏和标题栏。像 2 或 3 秒。为此，我尝试了 Timer，据我所知，功能请求( requestFeature() ) 必须在 SetContentView 和 Super.OnCreate 之前调用。所以，我写了这段代码：

@Override
protected void onCreate(Bundle savedInstanceState) {

    Timer timer = new Timer();
    timer.scheduleAtFixedRate(new TimerTask() {
        @Override
        public void run() {
            runOnUiThread(new Runnable() {
                @Override
                public void run() {
                    // TODO Auto-generated method stub
                    // Hiding Title bar of this activity screen //
                    getWindow().requestFeature(Window.FEATURE_NO_TITLE);

                    // Making this activity, full screen //
                    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);

                }
            });
        }
    }, 1000, 5000);


    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_splash);

但它伴随着以下错误：

android.util.AndroidRuntimeException: requestFeature() must be called before adding content

我认为 Timer 是错误的原因。因为，当我在没有 Timer 的情况下调用 requestFeature() 时，应用程序运行时没有显示任何错误或崩溃。

Is there any way to hide status and title bar for a specific time in the same layout? (Not Intent)

Answer 1

 Timer timer = new Timer();
        timer.scheduleAtFixedRate(new TimerTask() {
            @Override
            public void run() {
                runOnUiThread(new Runnable() {
                    @Override
                    public void run() {
                        // TODO Auto-generated method stub
                        // Hiding Title bar of this activity screen //
                         getSupportActionBar().hide();
                        // Making this activity, full screen //
                        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);

                    }
                });
            }
        }, 1000, 5000);
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_splash);

将 getWindow().requestFeature(Window.FEATURE_NO_TITLE); 替换为 getSupportActionBar().hide();。

Answer 2

使用下面的代码

全屏

 // Full Screen call using DecorView
 private void setFullScreen() {
           getWindow().addFlags(LayoutParams.FLAG_FULLSCREEN);
      }

从全屏移除

private void removeFromFullScreen() {
    getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
    getWindow().addFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);
  }

现在在你的 OnCreate()

@Override
protected void onCreate(Bundle savedInstanceState) {

   final android.os.CountDownTimer Count = new android.os.CountDownTimer(5000, 1000) {
 @Override
  public void onTick(long millisUntilFinished) {
   if (millisUntilFinished/1000 == 2) {
      setFFullScreen();
    }
   Log.e("TAG",millisUntilFinished/1000+"");
  }
  @Override
  public void onFinish() {
    removeFromFullScreen();
  }
};
Count.start();
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_splash);
