Android detect phone lock event
提问by Chris
I want to be able to detect the phone lock event. When my app is running, if I press the red button (call end button/power button), the phone gets locked and the screen goes blank. I want to be able to detect this event, is it possible?
我希望能够检测到电话锁定事件。当我的应用程序运行时，如果我按下红色按钮（通话结束按钮/电源按钮），手机会被锁定并且屏幕变黑。我希望能够检测到此事件，这可能吗？

Alternatively you could do this:
或者你可以这样做：
@Override
protected void onPause()
{
super.onPause();
// If the screen is off then the device has been locked
PowerManager powerManager = (PowerManager) getSystemService(POWER_SERVICE);
boolean isScreenOn;
if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT_WATCH) {
isScreenOn = powerManager.isInteractive();
} else {
isScreenOn = powerManager.isScreenOn();
}
if (!isScreenOn) {
// The screen has been locked
// do stuff...
}
}
