如何使用意向服务在活动中逐一调用五个服务

我已经与需要调用5到10个服务的应用程序一起工作。我必须逐个调用服务。完成第一个服务后，我需要打电话给第二个服务这是工作流程。我使用了意向服务来达到我的目的。如何以有效的方式实现这一点。如何使用意向服务在活动中逐一调用五个服务

这在MainActivity

public class MainActivity extends AppCompatActivity { 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 
     Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar); 
     setSupportActionBar(toolbar); 
     Intent service_1=new Intent(MainActivity.this,Service1.class); 
     startService(service_1); 
     Intent service_2=new Intent(MainActivity.this,Service2.class); 
     startService(service_2); 
     Intent service_3=new Intent(MainActivity.this,Service3.class); 
     startService(service_3); 

    } 

}

1服务

public class Service1 extends IntentService{ 

    public Service1() { 
     super("serviceone"); 
    } 



    @Override 
    protected void onHandleIntent(Intent intent) { 

     for(int i=0;i<1000;i++) 
     { 
      Log.e("service1","service1::............."+i); 
     } 

    } 
}

第二服务

public class Service2 extends IntentService { 

    public Service2() { 
     super("service2"); 
    } 

    @Override 
    protected void onHandleIntent(Intent intent) { 


     for(int i=0;i<100;i++) 
     { 
      Log.e("service2", "service::2*****************" + i); 
     } 

    } 
}

服3

public class Service3 extends IntentService{ 

    public Service3() { 
     super("service3"); 
    } 

    @Override 
    protected void onHandleIntent(Intent intent) { 

     for(int i=0;i<100;i++) 
     { 
      Log.e("service3", "service::3####################" + i); 
     } 
    } 
}

IAM获取日志

第二个方法

public class MainActivity extends AppCompatActivity { 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 
     Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar); 
     setSupportActionBar(toolbar); 

     //Intent service_2 = new Intent(MainActivity.this, Service2.class); 
     // startService(service_2); 
     //Intent service_3 = new Intent(MainActivity.this, Service3.class); 
     // startService(service_3); 




     AlarmManager alarmManager=(AlarmManager)getSystemService(Context.ALARM_SERVICE); 
     Intent intent1 = new Intent(MainActivity.this, AlarmReceiver.class); 
     PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, intent1, 0); 
     alarmManager.setRepeating(AlarmManager.RTC_WAKEUP,System.currentTimeMillis(),10000, 
       pendingIntent); 

    } 

}

广播接收机

public class AlarmReceiver extends BroadcastReceiver 
{ 

    @Override 
    public void onReceive(Context context, Intent intent) 
    { 
     //get and send location information 

     Intent service_1 = new Intent(context, Service1.class); 
     context.startService(service_1); 

     Intent service_2 = new Intent(context, Service2.class); 
     context.startService(service_2); 

    } 
}

服务类

public class Service1 extends IntentService{ 

    public Service1() { 
     super("serviceone"); 
    } 



    @Override 
    protected void onHandleIntent(Intent intent) { 

     forloopMethod(); 


    } 


    private void forloopMethod() 

    { 
     for(int i=0;i<10000;i++) 
     { 
      Log.e("service1","service1::.serviceone............"+i); 
     } 
    } 
}

同样得到我想打。经过第一服务第一完成服务调用，然后进行第二服务call.This是need..help我

你为什么不尝试用'BroadcastReceiver'？在每个“服务”开始之后，它会发送一条消息给'Activity'上注册的'BroadcastReceiver'。取决于该消息，请决定您现在要开始的服务。 –

请参阅下面的代码 –

您的意思是？在第二种方法中没有找到任何代码：（ –

当服务完成，以你可以发送广播让活动知道。

样品实施：

public class MainActivity extends AppCompatActivity { 
    public void onCreate() { 
     ... 
     mMyReceiver = new MyReceiver(this); 
     LocalBroadcastManager.getInstance(this).registerReceiver(mMyReceiver, new IntentFilter(SERVICE_FINISHED_ACTION)); 
    } 

    public void onDestroy() { 
     if (mMyReceiver != null) { 
      LocalBroadcastManager.getInstance(this).unregisterReceiver(mMyReceiver); 
     } 
     super.onDestroy(); 
    } 

    public void launchServiceTwo() { 
     Intent service2 = new Intent(MainActivity.this, Service2.class); 
     startService(service2); 
    } 

    ... 

    private static class MyReceiver extends BroadcastReceiver { 

     private final WeakReference<MainActivity> mWeakActivity; 

     public MyReceiver(@NonNull MainActivity activity) { 
      mWeakActivity = new WeakReference<>(activity); 
     } 

     @Override 
     public void onReceive(Context context, Intent intent) { 
      Bundle bundle = intent.getExtras(); 

      MainActivity listener = mWeakActivity.get(); 
      if (listener != null && bundle != null) { 
       String serviceFinishedExtra = bundle.getString(SERVICE_FINISHED_EXTRA); 
       if ("Service1".equalsIgnoreCase(serviceFinishedExtra)) { 
        launchServiceTwo(); 
       } else if ("Service2".equalsIgnoreCase(serviceFinishedExtra)) { 
        launchServiceThree(); 
       } else if ... 
      } 
     } 

    } 
} 

public class Service1 extends IntentService { 

    @Override 
    protected void onHandleIntent(Intent intent) { 
     ... 
     Intent broadcastIntent = new Intent(); 
     broadcastIntent.setAction(SERVICE_FINISHED_ACTION); 
     broadcastIntent.addCategory(Intent.CATEGORY_DEFAULT); 
     broadcastIntent.putExtra(SERVICE_FINISHED_EXTRA, "Service1"); 
     sendBroadcast(broadcastIntent); 
    } 

}

AlarmManager alarmManager =（AlarmManager）getSystemService（Context.ALARM_SERVICE）; Intent intent1 = new Intent（MainActivity.this， AlarmReceiver.class）; PendingIntent pendingIntent = PendingIntent.getBroadcast（thi s，0，intent1,0）; alarmManager.setRepeating（AlarmManager.RTC_WAKEUP，System.currentTimeMillis（），10000, pendingIntent）; –

我已经使用该代码每10秒调用一次该服务。如何将此代码集成到您的代码中？ –

请尝试更好地解释你想达到的目标。最初的问题是如何顺序调用各种服务。现在你说的是你正在使用报警管理器。这是为什么？你是否试图按顺序运行这些服务，并且每次都要重复一定的时间？ – fernandospr
