我正在尝试创建一个按钮,我可以在其中隐藏或显示平板电脑上的状态栏。
我已加入onCreate
getWindow().addFlags(WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);
并在按钮中 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);
任何提示/ tipps?
//修改
我在这里查看了这个提示:http://android.serverbox.ch/?p=306 并改变了我的代码:
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();
}
因此,如果我点击我的按钮,方法被调用我可以看到发生了什么,因为应用程序正在等待几秒钟。 我也调查了LockCat,发现事情正在发生。

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,我认为你不能全屏。
我会使用以下内容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,
以下是适合我的解决方案,(Documentation)(Flag Reference)
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);
}

对于Kotlin用户
要显示
Class MyClass {
var currentid: Int32?
}
NotificationCenter.default.addObserver(forName: ID_TRANSFER, object: nil, queue: nil){ notification in
if let object = notification.object as? [String: Any] {
if let currentidVal = object["UserID"] as? Int {
currentid = currentidVal
}
}
}
隐藏
activity?.window?.addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN)

我知道这是一个非常古老的问题,但以防万一有人在这里寻找最新的支持方式以编程方式隐藏状态栏,您可以按如下方式进行:
window.insetsController?.hide(WindowInsets.Type.statusBars())
并再次显示:
window.insetsController?.show(WindowInsets.Type.statusBars())

用于Android中的Kolin 用于kolin中的隐藏状态栏,无需在行尾使用
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);

我尝试了很多事情。
最后,它是最适合隐藏和显示全屏模式的代码。
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
}
}
它是在此应用中实现的: Android Breakdown 。

使用此方法,使用SYSTEM_UI_FLAG_IMMERSIVE_STICKY,只需轻按一下即可返回全屏,而无需执行任何操作。只需复制下面的此方法,然后在活动中的任意位置调用它即可。 更多详细信息here
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);
}
