推荐答案

简短的回答：这是不可能的。

Short answer: this is impossible!

现在，你应该有兴趣知道为什么这是不可能的：

Now should you be interested to know why this is impossible:

有操纵系统状态栏，<双权限href="http://developer.android.com/reference/android/Manifest.permission.html#EXPAND_STATUS_BAR">EXPAND_STATUS_BAR和<一href="http://developer.android.com/reference/android/Manifest.permission.html#STATUS_BAR">STATUS_BAR.前者可通过任何应用请求，但后来被保留用于与平台签名进行签名的应用程序（系统应用程序，而不是第三方）。它的可以的展开/折叠系统状态栏（见<一href="http://stackoverflow.com/questions/7021310/how-to-open-or-expand-status-bar-through-intent">"How打开或通过有意扩大状态栏？），但要注意，反射是必需的，因为<一href="http://grep$c$c.com/file/repository.grep$c$c.com/java/ext/com.google.android/android/2.3.4_r1/android/app/StatusBarManager.java?av=f">StatusBarManager类不是SDK的一部分。这种禁止功能的方法，它是从被扩展，不能由一个应用没有上述STATUS_BAR许可访问。所使用的机器人拨号到prevent状态栏

There are two permissions for manipulating the system status bar, EXPAND_STATUS_BAR and STATUS_BAR. The former can be requested by any application, but the later is reserved for applications signed with the platform signature (system applications, not third-party). It is possible to expand/ collapse the system status bar (see "How to open or expand status bar through intent?") but note that reflection is required because the StatusBarManager class is not part of the SDK. The disable method, which is used by the Android dialer to prevent the status bar from being expanded, cannot be accessed by an application without the aforementioned STATUS_BAR permission.
