我遇到一个由AlarmManager调用的代码有问题。 我调用wakeLock来执行任务，以便将数据传输到Web服务 我的唤醒锁执行得很好，在我上传后，我调用方法发布 但在那之后，我的设备不再用电源按钮锁定，我不明白为什么......（为了解释，设备屏幕关闭但是当我再次按下时锁定屏幕不再出现电源按钮，它是解锁的） 如果有人可以帮助我
我的代码：

答案 0 :(得分：0)
我设法通过更改newWakeLock的标志来重新激活锁定屏幕 我之前有：PowerManager.SCREEN_BRIGHT_WAKE_LOCK | PowerManager.FULL_WAKE_LOCK | PowerManager.ACQUIRE_CAUSES_WAKEUP
现在：PowerManager.ACQUIRE_CAUSES_WAKEUP | PowerManager.ON_AFTER_RELEASE | PowerManager.SCREEN_BRIGHT_WAKE_LOCK
我认为是FULL_WAKE_LOCK是问题
