如何停止我的应用程序在android中的服务？

Question

我写了一个服务和广播接收器类。该服务与任务绑定。我可以成功启动服务和广播接收机。我也可以停止广播接收器。但我无法停止我的服务。

这是我的代码来启动和停止服务。

public class Pedometer extends Activity { 


    private boolean mIsRunning; 

    public static Context mContext; 

    private StartAtBootServiceReceiver receiver; 
    private SharedPreferences prefs; 

    /** Called when the activity is first created. */ 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 

     mContext = getBaseContext(); 

     setContentView(R.layout.main); 

     prefs = getApplicationContext().getSharedPreferences(
        "com.sa.sademo", Context.MODE_PRIVATE); 

     receiver = new StartAtBootServiceReceiver(); 
     IntentFilter filter = new IntentFilter(Intent.ACTION_BOOT_COMPLETED); 
     mContext.registerReceiver(receiver, filter); 

     Button stopServiceAndBR = (Button) findViewById(R.id.stopServiceAndBR); 
     bankButton.setOnClickListener(new View.OnClickListener() { 

      @Override 
      public void onClick(View v) { 
       Pedometer.this.stopStepService(); 
      } 
     }); 

     startStepService(); 
    } 


    public static Context getContext() { 
     return mContext; 
    } 

    @Override 
    protected void onResume() { 
     super.onResume(); 

     if (mIsRunning) { 
      bindStepService(); 
     } 
    } 

    @Override 
    protected void onPause() { 
     if (mIsRunning) { 
      unbindStepService(); 
     } 
     super.onPause(); 
    } 

    @Override 
    protected void onDestroy() { 
     // TODO Auto-generated method stub 
     super.onDestroy(); 
    } 

    @Override 
    protected void onStop() { 
     // TODO Auto-generated method stub 
     super.onStop(); 
    } 

    private StepService mService; 

    private ServiceConnection mConnection = new ServiceConnection() { 
     public void onServiceConnected(ComponentName className, IBinder service) { 
      mService = ((StepService.StepBinder)service).getService(); 
     } 

     public void onServiceDisconnected(ComponentName className) { 
      mService = null; 
     } 
    }; 


    private void startStepService() { 
     mIsRunning = true; 
     startService(new Intent(Pedometer.this, 
       StepService.class)); 
    } 

    private void bindStepService() { 
     bindService(new Intent(Pedometer.this, 
       StepService.class), mConnection, Context.BIND_AUTO_CREATE); 
    } 

    private void unbindStepService() { 
     unbindService(mConnection); 
    } 

    private void stopStepService() { 
     mIsRunning = false; 
     if (mService != null) { 
       PackageManager pm = mContext.getPackageManager(); 
       ComponentName component = new ComponentName(mContext, StartAtBootServiceReceiver.class); 
       pm.setComponentEnabledSetting(component , PackageManager.COMPONENT_ENABLED_STATE_DISABLED , PackageManager.DONT_KILL_APP); 

       unbindStepService(); 
       mIsRunning = false; 
       if (mService != null) { 
        stopService(new Intent(Pedometer.this, 
          StepService.class)); 
       } 
     } 
    } 
} 

Answer 1

您的服务中，你可以做：

//A variable to check 
boolean cancel = false; 

//a method to set this variable 
public void cancel(){ 
    cancel = true; 
} 

//inside of some point of your service you do: 

while (yourCondition){ 

    if (!cancel){ 

    //do the service work 

    } else { 

    throw new StopServiceException(); // you have to create it. 
    } 

} 

内部与服务实例的aplication调用取消方法：

myService.cancel();
