推荐答案

要禁用状态NotificationBar：

Its possible

To disable the Status NotificationBar:

您需要放置在通知栏上方的观点，使我们劫持触摸事件的状态通知栏。事不宜迟，这里是code：

You need to place a view on top of the notification bar, so that we hijack the touch events to the Status notification bar. Without further ado, here is the code:

mView= new TextView(this);                                       
mView.setText(".........................................................................");                       

mLP = new WindowManager.LayoutParams(
        WindowManager.LayoutParams.MATCH_PARENT,
        100,
        // Allows the view to be on top of the StatusBar
        WindowManager.LayoutParams.TYPE_SYSTEM_ERROR,
        // Keeps the button presses from going to the background window
        WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE |
        // Enables the notification to recieve touch events
        WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL |
        // Draws over status bar
        WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN,
        PixelFormat.TRANSLUCENT);

mLP.gravity =  Gravity.TOP|Gravity.CENTER;      

mWindowManager = (WindowManager) getSystemService(WINDOW_SERVICE);
mWindowManager.addView(mView, mLP);

既然你正在使用的系统覆盖窗口，你所需要的权限：

And since you are using the system overlay window, you need the permission:

<uses-permission android:name="android.permission.SYSTEM_OVERLAY_WINDOW" />

请注意：

不要让你的应用程序全屏，作为上述版本17，支持身临其境的模式，会搞砸了这种方法。

Do not make your app full screen, as the versions above 17, which supports immersive mode, will screw this approach.
