Question

我试图停止我的服务，即使我的 destroy 方法也已执行但我的服务没有停止。我已经尽力了。请帮帮我。

我的代码如下：

MainActivity

Intent intent = new Intent（this，Myservice.class）;
startService（意向）; //在开始按钮中。
Intent intent = new Intent（this，Myservice.class）;
stopService（意向）; //在停止按钮。

MYSERVICE

public class Myservice extends Service {
@Nullable
@Override
public IBinder onBind(Intent intent) {
    return null;
}

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

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    Toast.makeText(this,"runing",Toast.LENGTH_LONG).show();

     {
         myTherad th=new myTherad();
         Thread thread=new Thread(th);
         thread.start();


     }

    return super.onStartCommand(intent, flags, startId);

}

@Override
public void onDestroy() {
    Toast.makeText(this,"stop",Toast.LENGTH_LONG).show();
    super.onDestroy();

}

class myTherad implements Runnable {

    @Override
    public void run() {
        synchronized (this)
        {
            try {

                for(int i=0;i<10;i++)
                {
                    wait(1000);
                    Log.d("mfnhsdgjkfn","===="+String.valueOf(i));
                }

            } catch (InterruptedException e) {
                e.printStackTrace();
            }

        }
        stopSelf();


    }


}

}

我认为您的服务已停止，但不是Thread。通过引入以下内容，在onDestroy您的服务中取消您的主题某种状态变量：

 class myTherad implements Runnable {
     // Indicates that the runnable should stop. 
     private boolean shouldStop = false;

     @Override
     public void run() {
        synchronized (this)
        {
            try {

                for(int i=0;i<10 && !shouldStop;i++)
                {
                    wait(1000);
                    Log.d("mfnhsdgjkfn","===="+String.valueOf(i));
                }

            } catch (InterruptedException e) {
                e.printStackTrace();
            }

        }
        stopSelf();


  }

并将runnable声明为class属性：

private myTherad runnable;

@Override
public int onStartCommand(Intent intent, int flags, int startId) {

    runnable=new myTherad();
    Thread thread=new Thread(runnable);
    thread.start();

    return super.onStartCommand(intent, flags, startId);

}

并停止onDestroy中的runnable：

@Override
public void onDestroy() {
    Toast.makeText(this,"stop",Toast.LENGTH_LONG).show();
    runnable.shouldStop = true;
    super.onDestroy();

}

至少在执行最新的wait之后，您的线程应该停止。你可以通过中断来优化它。

我们必须使用正在运行的线程，thread.interrupt()将执行此操作并提供java.lang.InterruptedException，请尝试以下代码：

public class MyService extends Service {
public MyService() {}
myTherad th;
Thread thread;

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

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

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    Toast.makeText(this,"runing",Toast.LENGTH_LONG).show();

    {
         th=new myTherad();
         thread=new Thread(th);
         thread.start();
    }
    return super.onStartCommand(intent, flags, startId);
}

@Override
public void onDestroy() {
    super.onDestroy();
    Toast.makeText(this,"stop",Toast.LENGTH_LONG).show();
    thread.interrupt();
}

class myTherad implements Runnable {

    @Override
    public void run() {
        synchronized (this)
        {
            try {

                for(int i=0;i<10;i++)
                {
                    wait(1000);
                    Log.d("LOG","===="+String.valueOf(i));
                }

            } catch (InterruptedException e) {
                e.printStackTrace();
            }

        }
        stopSelf();
    }
}
}

如何手动停止服务？
