错误的数据进行解析java.lang.IllegalStateException：不就当试图添加标记

-2

我试图更新使用服务上的谷歌地图标记，但是当我使用“setParkingSpotMarker”功能，添加标记主线程列表中的每个项目都会收到错误“java.lang.IllegalStateException：Not on the main thread”错误的数据进行解析java.lang.IllegalStateException：不就当试图添加标记

函数“setParkingSpotMarker”在服务-DataUpdateService中的循环中调用。

我不知道如何改变我的代码，以便它会更新主thread.I标记看了一下，有些职位，但不知道如何去改变它在我的代码。

这是该服务：

package com.example.sailon; 
    import android.app.Service;

    }

     return mBinder; 
    } 

    public class LocalBinder extends Binder { 
     DataUpdateService getService() { 
      Log.d("PS", "DataUpdateService LocalBinder onBind"); 
      return DataUpdateService.this; 
     } 
    } 

    public class MyTimerTask extends TimerTask { 
     @Override

      if (isSailor){ 
       gps = new GPSTracker(DataUpdateService.this,unitToUpdate); 
       if(! (gps.canGetLocation())){  
        gps.showSettingsAlert(); 
       } 
      } 

      unitswithteam=mymap.refresh (CompName,heatNum); 

      int j= unitswithteam.size(); 
      for (int i=0; i<j;i++){ 
       teamID=unitswithteam.get(i).getTeamID(); 
       Log.d("NY","teamID "+i+teamID); 
       UnitsInHeats us=unitswithteam.get(i).getUnit(); 
       teamLocation = new LatLng(us.getLat(),us.getLng()); 
       Log.d("NY","team location "+i + " "+us.getLat()); 
       mymap.setParkingSpotMarker(teamLocation,teamID); 

       if (i==(j-1)){ 
        CameraPosition secound =new CameraPosition.Builder() 
        .target(teamLocation) 
        .zoom(15.5f) 
        .bearing(300) 
        .tilt(50) 
        .build(); 
        mymap.moveMyMapCamera(secound); 
       } 
     } 

     } 
    } 

    // called from the activity 
    public void MapUpdateFromService(Context context, MyMap map, final String action, 
           String CompName, String heatNum, boolean isSailor , String usermail) { 
     Log.d("PS", "DataUpdateService MapUpdateFromService"); 
     this.mymap = map; 
     this.action = action; 
     this.CompName=CompName; 
     this.heatNum=heatNum; 
     this.isSailor=isSailor; 
     this.usermail=usermail; 

     // this command activate the run function from the inner class MyTimerTask every 5 seconds. 
     myTimer.schedule(myTask,0,5000); 
    } 


    public void onDestroy() { 
     super.onDestroy(); 
     // cancel the scheduler. 
     myTimer.cancel(); 
    } 
}

请帮我感谢！**

在后台线程上运行TimerTask的run方法，你只能更新主线程在地图上。

所以，你必须在以下地图UI更新代码包装成runOnUiThread(）

 mymap.setParkingSpotMarker(teamLocation,teamID); 

     if (i==(j-1)){ 
      CameraPosition secound =new CameraPosition.Builder() 
      .target(teamLocation) 
      .zoom(15.5f) 
      .bearing(300) 
      .tilt(50) 
      .build(); 
      mymap.moveMyMapCamera(secound); 
     }

你需要有一个Activity申请runOnUIThread，所以你需要把你的

fromContext = ((Map)context);

在您的MapUpdateFromService方法的第一行内。然后，您可以拨打的run()方法拨打runOnUiThread()。

((Map)fromContext).runOnUiThread(new Runnable() { 
    @Override 
    public void run() { 
     //run your Map UI update code 
    } 
});

这也是一个类似的问题this problem。
