我正在尝试建立一个类似待机的活动，并且我已经接近我的目标，我发现的唯一问题是有时在我关闭屏幕后，Android 会立即打开它，但我不明白为什么。

我有一个连接到专有板的终端，当我启动特定活动时，我可以让板向我的设备发送消息以关闭屏幕。结果是屏幕关闭，但只是片刻，因为 Android 立即打开屏幕。

这是我的应用程序的日志

         V/KeyguardServiceDelegate( 2147): **** SHOWN CALLED ****
         I/WindowManager( 2147): No lock screen! windowToken=null

我看不懂的奇怪日志是这一行

         D/InputManager-JNI( 2147): handleInterceptActions: Waking up.

似乎 InputManager 类以某种方式接收到唤醒屏幕的输入，即使我没有输入。有人知道为什么会这样吗？

D/InputManager-JNI（2147）：handleInterceptActions：醒来。

这意味着带有策略标志“wake”的键或其他事件即将到来。
