如何获取手机从睡眠模式下返回Android

PowerManager powerManager = (PowerManager) getSystemService(Context.POWER_SERVICE);
PowerManager.WakeLock wakeLock = powerManager.newWakeLock(PowerManager.FULL_WAKE_LOCK | PowerManager.ACQUIRE_CAUSES_WAKEUP, "MyApp:MyWakeLock");
wakeLock.acquire();

AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
Intent intent = new Intent(this, MyReceiver.class); // 自定义的广播接收器
PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, intent, 0);
alarmManager.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + 1000, pendingIntent); // 在当前时间1秒后唤醒设备

public class MyReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        if (intent.getAction().equals(Intent.ACTION_SCREEN_ON)) {
            // 执行相应的操作
        }
    }
}
