我在公共无效越来越例外 sendOrder（）行

 适配器=新OrdersAdapter（KitchenManager.this，R.layout.kitchen_order_list，this.orderList）;
 

请如果任何人能帮助我，因为我做了搜索，但无法找到解决我的问题。先谢谢了。

解决方案

  KitchenManager厨房=新KitchenManager（）;
 

不要试图做到这一点！

您无法使用新实例化一个活动。这不是Android的是如何工作的。

如果你想开始一个活动从服务你应该用做一个通知和的PendingIntent 。

I'm getting this exception System services not available to Activities before onCreate() when I'm trying to set adapter outside of my onCreate() method.
I have tried using runOnUIThread() function but still couldn't solve my problem.
Here is my code actually.
I'm sending a list from my Service subclass to my activity class via a method.

Class KitchenSerivce extends Service
@Override
public int onStartCommand(Intent intent, int flags , int startId)
{   
    super.onStartCommand(intent, flags, startId);   
    Toast.makeText(this, "Service started ...", Toast.LENGTH_SHORT).show();

    try
    {
        SoapObject result=null;
        SoapObject request=new SoapObject(NAME_SPACE, METHOD_NAME);

        SoapSerializationEnvelope envelope=new SoapSerializationEnvelope(SoapEnvelope.VER11);
        envelope.dotNet=true;
        envelope.setOutputSoapObject(request);

        try
        {
            HttpTransportSE androidHttpTransportSE=new HttpTransportSE(URL, 5000);
            androidHttpTransportSE.call(SOAP_ACTION, envelope);

            result=(SoapObject)envelope.getResponse();
            orderList=getOrder(result);

            Log.v("Server response", result.toString());
        }
        catch (Exception e)
        {
            msg=Toast.makeText(this, "Connection to Server Failed", Toast.LENGTH_SHORT);
            msg.show();             
        }

        msg=Toast.makeText(this, result.toString(), Toast.LENGTH_SHORT);
        msg.show();

        KitchenManager kitchen=new KitchenManager();        
        kitchen.sendOrder(orderList);
    }                   
    catch (Exception e)     
    {               
        System.out.println("Exception Caught:"+e.getMessage());         
    }

    return START_STICKY;        
}

KitchenManager extends Activity

public void sendOrder(List<Order> orderList)
{

    this.orderList=orderList;

    for(int i=0;i<orderList.size();i++)
    {
        System.out.println("List Size:"+orderList.size());
        System.out.println("Item:"+orderList.get(i).getItem());
    }

    adapter=new OrdersAdapter(KitchenManager.this,R.layout.kitchen_order_list,this.orderList);

    if(this.orderList.size()==0)
    {

    }
    else
    {
    list.setAdapter(adapter);
    adapter.notifyDataSetChanged();
    }
}

---

I'm getting exception in public void sendOrder() on line

adapter=new OrdersAdapter(KitchenManager.this,R.layout.kitchen_order_list,this.orderList);

Please if any one could help me because I'm done searching but can't find solution to my problem. Thanks in advance.

解决方案

KitchenManager kitchen=new KitchenManager();

Don't try to do this!!!

You cannot instantiate an Activity using new. This is NOT how Android works.

If you want to start an Activity from a Service you should do it using a Notification and a PendingIntent.
