Display view above status bar?
提问by user1190019
I recently saw an image of an app that was capable of displaying a view above the status bar and was also able to cover it with a view.
我最近看到了一个应用程序的图像，它能够在状态栏上方显示一个视图，也能够用一个视图覆盖它。
I know you can get a view right below the status bar from a view with align parent top. But how would you get a view on top of the status bar??
我知道您可以从对齐父顶部的视图中获得状态栏正下方的视图。但是如何在状态栏顶部获得视图？

Disable the System Status Bar - Without Root
禁用系统状态栏 - 无 Root
After two full days of searching through SO posts and reading the Android docs over and over.. Here is the solution that I came up with. (tested)
经过整整两天搜索SO帖子并一遍又一遍地阅读Android文档..这是我想出的解决方案。（已测试）
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);
Dont forget the permissions:
不要忘记权限：
<uses-permission android:name="android.permission.SYSTEM_OVERLAY_WINDOW" />
Note:
Tested upto kitkat.

The answer by @Sadeshkumar is incorrect for ICS and above (perhaps GB as well).
@Sadeshkumar 的答案对于 ICS 及更高版本（可能也是 GB）是不正确的。
A view created with TYPE_SYSTEM_ALERTand FLAG_LAYOUT_IN_SCREENis covered by the StatusBar.
使用TYPE_SYSTEM_ALERT和创建的视图FLAG_LAYOUT_IN_SCREEN被 覆盖StatusBar。
To get an overlay on top of the StatusBar, you need to use TYPE_SYSTEM_OVERLAYinstead of TYPE_SYSTEM_ALERT.
要在 之上获得叠加层StatusBar，您需要使用TYPE_SYSTEM_OVERLAY代替TYPE_SYSTEM_ALERT。
The problem being then, how to get clicks/touches?
那么问题来了，如何获得点击/触摸？

int statusBarHeight = (int) Math.ceil(25 * getResources().getDisplayMetrics().density);
View statusBarView = new View(MyActivity.this);
statusBarView.setBackgroundColor(Color.GREEN);
WindowManager.LayoutParams params = null;
params = new WindowManager.LayoutParams(WindowManager.LayoutParams.FILL_PARENT,statusBarHeight,WindowManager.LayoutParams.TYPE_SYSTEM_ALERT,WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL |WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN, PixelFormat.TRANSLUCENT);
params.gravity = Gravity.RIGHT | Gravity.TOP;
WindowManager wm = (WindowManager) getSystemService(WINDOW_SERVICE);
wm.addView(statusBarView, params);
