Answer 1

使用广播呀，接收电源键按下的广播 class PowerKeyBroadcastReceiver extends BroadcastReceiver{
@Override
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
if (action.equals(Intent.ACTION_SCREEN_OFF)) {
// 电源键按下
}
}
}

BroadcastReceiver   Intent.ACTION_SCREEN_OFF监听锁屏，Intent.ACTION_SCREEN_ON亮屏
