android - 停止 Activity 中的服务

Question

我正在使用以下代码来停止我的服务

Intent intent = new Intent(MainActivity.this, UsageRecorderService.class);
stopService(intent);

这是我的无限期服务

public class UsageRecorderService extends IntentService {

  public UsageRecorderService() {
      super("UsageRecorder");
  }

  @Override
  protected void onHandleIntent(Intent intent) {

      while (true) {

          UsageRecorder.recordUsages(this, false);

          SystemClock.sleep(10000);
      }
   }
}

为什么不停止我的服务？

Answer 1

这段代码可以工作

public class UsageRecorderService extends IntentService {

    private boolean mStop = false;

    public UsageRecorderService() {
        super("UsageRecorder");
    }

    public final Object sLock = new Object();

    public void onDestroy() {
        synchronized (sLock) {
            mStop = true;
        }
    }


    @Override
    protected void onHandleIntent(Intent intent) {
        while (true) {
            synchronized (sLock) {
                if (mStop) break;
            }
            UsageRecorder.recordUsages(this, false);
            SystemClock.sleep(10000);
        }
    }

}

您可以使用stopService

Intent intent = new Intent(MainActivity.this, UsageRecorderService.class);
stopService(intent);

我还建议阅读Services guide了解那里发生了什么。
