Android的 - 激活系统钥匙锁（又称锁屏） [英] Android - Activation of the system key lock (aka lock screen)

问题描述

我要激活Android的系统钥匙锁（一个你当你preSS的的关机的/ *挂断*键）。在这里看到：

I have to activate android's system key lock (the one you get when you press the power off/*hang up* button). See here:

我已经浏览过的文档，但一切我发现是 PowerManager的并 KeyguardManager 。这两个似乎没有解决： - （

I already browsed the docs but everything I found was PowerManager and KeyguardManager. Both seem not to be the solution :-(.

所以，每个人都知道如何做到这一点从Android应用程序？ （如有特殊权限是必需的，这是没有问题的，但是改变设备的设置是不是一个解决办法...）

So, does everyone know how to achieve that from a android application? (If special permissions are required, that is no problem but changing the device's settings is not a solution...)

修改：还是没有人知道这是绝对不可能的呢？顺便说一句。与发送键克雷格斯解决方案不工作了（见注释）。

EDIT: Or does someone know that this is definitely not possible at all? Btw. craigs solution with sending keys does not work anymore (see comments).

推荐答案

我一直在寻找一个答案了一段时间的确切同样的问题。显然，2.0后开始拆除设备管理权限的应用水平。但随着升级Froyo - 2.2设备策略管理器发现给予我们开发了大量的行政级别控制

I have been searching for an answer to the exact same question for a while. Apparently, after 2.0 onwards the device manager privileges for the app level were removed. But with Froyo - 2.2 the device policy manager is revealed granting us developers a multitude of administrative level controls.
