如何在我的应用程序中锁定特定 Activity 中的状态栏和通知栏
How to lock status bar and notification bar in a specific Activity in my application
我正在处理与考试相关的 android 申请。考试开始时我需要锁定状态栏和通知栏。我使用了下面的代码,但它只隐藏了状态栏和通知栏。
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
//Remove notification bar
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
有什么方法可以锁定状态栏和通知栏而不是隐藏它们。对于任何积极的回应,提前致谢。
锁定通知栏是什么意思?你是说暂时收不到任何通知?
关于你的问题。您可以做的是让您的工具栏不可点击,或者更具体地说,让抽屉式导航栏不可点击,这样用户就无法打开它。

你可以这样做:
WindowManager manager = ((WindowManager) getApplicationContext()
.getSystemService(Context.WINDOW_SERVICE));
WindowManager.LayoutParams localLayoutParams = new WindowManager.LayoutParams();
localLayoutParams.type = WindowManager.LayoutParams.TYPE_SYSTEM_ERROR;
localLayoutParams.gravity = Gravity.TOP;
localLayoutParams.flags = WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE|
// this is to enable the notification to recieve touch events
WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL |
// Draws over status bar
WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN;
localLayoutParams.width = WindowManager.LayoutParams.MATCH_PARENT;
localLayoutParams.height = (int) (50 * getResources()
.getDisplayMetrics().scaledDensity);
localLayoutParams.format = PixelFormat.TRANSPARENT;
customViewGroup view = new customViewGroup(this);
manager.addView(view, localLayoutParams);
