如何在检测到android.intent.action.USER_PRESENT时运行代码？

Question

我只需要在检测到android.intent.action.USER_PRESENT时运行代码，并且我已经创建了一个运行线程来执行此操作的服务，但这是正确的方法吗？我的意思是，当检测到android.intent.action.ACTION_SCREEN_ON时，我的服务再次启动并且什么都不做，因为运行代码的条件是android.intent.action.USER_PRESENT。

这是我的服务类：

public class MyService extends Service {
private _Thread thread = new _Thread();
ExecutorService executor = Executors.newSingleThreadExecutor();
private KeyguardManager kM;
private boolean isLocked, wasLocked;

@Override
public IBinder onBind(Intent arg0) {
    return null;
}

@Override
public void onCreate(){
    super.onCreate();        

    IntentFilter filter = new IntentFilter();
    filter.addAction(Intent.ACTION_SCREEN_ON);
    filter.addAction(Intent.ACTION_SCREEN_OFF);
    filter.addAction(Intent.ACTION_USER_PRESENT);
    registerReceiver(mReceiver, filter);

    kM = (KeyguardManager) getSystemService(Context.KEYGUARD_SERVICE);
}

@Override
public int onStartCommand(Intent intent, int flags, int startId) {     
    isLocked = kM.inKeyguardRestrictedInputMode();

    executor.execute(thread);
    thread.running = true;

    if (!isLocked) {            
        thread.runMyCode = true;
    }
    executor.shutdown();
    Toast.makeText(this, "Service Started", Toast.LENGTH_LONG).show();
    return START_STICKY;
}

public class _Thread implements Runnable {
    private boolean running, runMyCode;

    public void run(){
        while (running) {
            try {
                Thread.sleep(500);                        
            } catch (InterruptedException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            if (runMyCode){
                // Run my code or method
            }
        }          
        stopSelf();
    }
}

private final BroadcastReceiver mReceiver = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {
        isLocked = kM.inKeyguardRestrictedInputMode();

        if (intent.getAction().equals(Intent.ACTION_SCREEN_ON)){
            if (!isLocked) {
                thread.runMyCode = true;
                wasLocked = false;
            }
        }

        if (intent.getAction().equals(Intent.ACTION_SCREEN_OFF)){
            if (!wasLocked){
                thread.runMyCode = false;                    
                wasLocked = true;
            }
        }

        if (intent.getAction().equals(Intent.ACTION_USER_PRESENT)){               
            wasLocked = false;
            thread.runMyCode = true;
        }
    }
};

@Override
public void onDestroy() {
    super.onDestroy();

    thread.running = false;
    unregisterReceiver(mReceiver);

    Toast.makeText(this, "Service Destroyed", Toast.LENGTH_LONG).show();
}

}
