Android 尽管出现了窗口弹出窗口、覆盖图或对话框，但如何隐藏导航栏？
我正在尝试创建一个在特定时间启动的全屏应用程序，当它启动时，它应该自动变成全屏。我可以全屏启动它。但是，如果存在弹出窗口或窗口，然后启动“我的活动”，则导航栏永远不会隐藏（换句话说，不会达到全屏状态）。我制作了一个5秒的视频来演示这个问题 您可以在此处查看错误： 我试过用旗子做任何事情，但似乎都做不到。我环顾了Playstore，似乎许多锁屏应用程序特别容易隐藏导航栏，尽管存在任何弹出窗口\其他对话框（SlideLock、Echo锁屏） 下面是我的简单活动代码： 在清单中：Android 尽管出现了窗口弹出窗口、覆盖图或对话框，但如何隐藏导航栏？,android,dialog,popup,fullscreen,navbar,Android,Dialog,Popup,Fullscreen,Navbar,我正在尝试创建一个在特定时间启动的全屏应用程序，当它启动时，它应该自动变成全屏。我可以全屏启动它。但是，如果存在弹出窗口或窗口，然后启动“我的活动”，则导航栏永远不会隐藏（换句话说，不会达到全屏状态）。我制作了一个5秒的视频来演示这个问题 您可以在此处查看错误： 我试过用旗子做任何事情，但似乎都做不到。我环顾了Playstore，似乎许多锁屏应用程序特别容易隐藏导航栏，尽管存在任何弹出窗口\其他对话框（SlideLock、Echo锁屏） 下面是我的简单活动代码： 在清单中： windowlayo

也许我的行为与你的目标相似，但我的答案需要重新考虑。
不管怎样，这是我的解决方案
我添加了两个组件：
折叠状态栏面板的方法
听众在所有活动前发起一个全新的活动
第一部分相当简单：您只需在活动中使用此方法：
private void collapseStatusBar(){
Object statusBarService = getSystemService("statusbar");
Class<?> statusBarManager = null;
try {
statusBarManager = Class.forName("android.app.StatusBarManager");
} catch (ClassNotFoundException e) {
e.printStackTrace();
}
Method collapseStatusBar = null;
try {
// Prior to API 17, the method to call is 'collapse()'
// API 17 onwards, the method to call is `collapsePanels()`
if (Build.VERSION.SDK_INT > 16) {
collapseStatusBar = statusBarManager.getMethod("collapsePanels");
} else {
collapseStatusBar = statusBarManager.getMethod("collapse");
}
} catch (NoSuchMethodException e) {
e.printStackTrace();
}
collapseStatusBar.setAccessible(true);
try {
collapseStatusBar.invoke(statusBarService);
} catch (IllegalArgumentException e) {
e.printStackTrace();
} catch (IllegalAccessException e) {
e.printStackTrace();
} catch (InvocationTargetException e) {
e.printStackTrace();
}
}
这是接收器：
public class LaunchWakeupReceiver extends BroadcastReceiver {
@Override
public void onReceive(final Context context, Intent intent) {
intent = new Intent(context,MainActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(intent);
}
}
例如，您的主要活动可能如下：
public class MainActivity extends AppCompatActivity {
