Android:显示/隐藏状态栏/电源栏

我正在尝试创建一个按钮，我可以在我的平板电脑上隐藏或显示状态栏。

我输入了onCreate

getWindow().addFlags(WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);

和按钮显示:

WindowManager.LayoutParams attrs = getWindow().getAttributes();
attrs.flags &= ~WindowManager.LayoutParams.FLAG_FULLSCREEN;
getWindow().setAttributes(attrs);

隐藏:

WindowManager.LayoutParams attrs = getWindow().getAttributes();
attrs.flags |= WindowManager.LayoutParams.FLAG_FULLSCREEN;
getWindow().setAttributes(attrs);

提示/tipp吗?

//编辑

我看了这个提示:http://android.serverbox.ch/?p=306然后像这样修改我的代码:

private void hideStatusBar() throws IOException, InterruptedException {
    Process proc = Runtime.getRuntime().exec(new String[]{"su","-c","service call activity 79 s16 com.android.systemui"});
    proc.waitFor();
}
private void showStatusBar() throws IOException, InterruptedException {
    Process proc = Runtime.getRuntime().exec(new String[]{"am","startservice","-n","com.android.systemui/.SystemUIService"});
    proc.waitFor();
}

如果我点击我的按钮，方法被调用，我可以看到一些事情正在发生，因为应用等待了几秒钟。我还查看了LockCat，发现有些事情正在发生。

您是否在清单中设置了全屏主题?

android:theme="@android:style/Theme.NoTitleBar.Fullscreen"

如果没有这个，你可能无法全屏播放。

我将使用以下代码添加和删除全屏标志:

// Hide status bar
getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
// Show status bar
getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);

对于某些人，通过清除FLAG_FULLSCREEN显示状态栏可能不起作用，

这是为我工作的解决方案，(文档)(标志参考)

隐藏状态栏

// Hide Status Bar
if (Build.VERSION.SDK_INT < 16) {
            getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                    WindowManager.LayoutParams.FLAG_FULLSCREEN);
}
else {
   View decorView = getWindow().getDecorView();
  // Hide Status Bar.
   int uiOptions = View.SYSTEM_UI_FLAG_FULLSCREEN;
   decorView.setSystemUiVisibility(uiOptions);
}

显示状态栏

   if (Build.VERSION.SDK_INT < 16) {
              getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
    }
    else {
       View decorView = getWindow().getDecorView();
      // Show Status Bar.
       int uiOptions = View.SYSTEM_UI_FLAG_VISIBLE;
       decorView.setSystemUiVisibility(uiOptions);
    }

用于android中的kolin对于在kolin中隐藏状态栏，不需要在

行末尾使用分号(;)

window.addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN)

在android中使用Java语言隐藏状态栏

getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);

我知道这是一个非常古老的问题，但万一有人在这里寻找最新支持的方式来隐藏状态栏编程，你可以这样做:

window.insetsController?.hide(WindowInsets.Type.statusBars())

再显示一次:

window.insetsController?.show(WindowInsets.Type.statusBars())

我已经尝试过很多方法了。

最后，它是隐藏和显示全屏模式最合适的代码。

private fun hideSystemUi() {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.R) {
        window.setDecorFitsSystemWindows(true)
    } else {
        // hide status bar
        getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
        window.decorView.systemUiVisibility =
            View.SYSTEM_UI_FLAG_IMMERSIVE or View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
    }
}
private fun showSystemUi() {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.R) {
        window.setDecorFitsSystemWindows(false)
    } else {
        // Show status bar
        window.clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
        window.decorView.systemUiVisibility = SYSTEM_UI_FLAG_LAYOUT_STABLE
    }
}

转到视频(底部栏)>播放任意视频>切换全屏

 @Override
 protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    //hide status bar
    requestWindowFeature( Window.FEATURE_NO_TITLE );
    getWindow().setFlags( WindowManager.LayoutParams.FLAG_FULLSCREEN,
            WindowManager.LayoutParams.FLAG_FULLSCREEN );

    setContentView(R.layout.activity_main);
}

对于Kotlin用户

显示

activity?.window?.addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN)

隐藏

activity?.window?.clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN)

使用这个方法，使用SYSTEM_UI_FLAG_IMMERSIVE_STICKY，一键返回全屏，不需要任何实现。只需复制下面的方法，并在你想要的活动中调用它。更多细节在这里

private void hideSystemUI() {
    getWindow().getDecorView().setSystemUiVisibility(
            View.SYSTEM_UI_FLAG_IMMERSIVE
                    // Set the content to appear under the system bars so that the
                    // content doesn't resize when the system bars hide and show.
                    | View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                    | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                    | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                    // Hide the nav bar and status bar
                    | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY
                    | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
                    | View.SYSTEM_UI_FLAG_FULLSCREEN);
}
