如何在没有膨胀

Question

我对此代码有疑问。代码在Main Activity中，ArtGeneralButton是一个填充特定列表视图的按钮。因此，有一个负责更新的类（UpdateAnsList）。我使用一个名为StartUpdateAnsList的方法。但是

有问题

 listView = (ListView) findViewById(R.id.listView11);

我需要为名为SelectAtivity的Activity充气，因为listview11位于此Activity（布局）中。我不想使用所有代码来膨胀。可以使用不同的东西吗？

MainActivity

  ...
public void ArtGeneralButton(View view){
     selsub = view.getId();
     UpdateAnsList myUpdate = new UpdateAnsList();      
     myUpdate.StartUpdateAnsList(this, selsub);


}
...

UpdateAnsList

...

public class UpdateAnsList {

    /**
     * @param args
     */
    final static String ARG_POSITION_ANSWER = "position";
    private String jsonResult;
    private ListView listView;
    private Context context;
    public int selsub;

    public UpdateAnsList(){


    }



    public void StartUpdateAnsList(Context c, int v){
        listView = (ListView) findViewById(R.id.listView11);
        context = c;
        selsub = v;
        selectItemAns(selsub);
        accessWebService();
    }

    private void selectItemAns(int position) {


        switch(position){   
        case R.id.button001:
            \\action
            break;

        case 0:
            \\action
            break; 

        case 2:
            \\action
            break; 

        case 3:

            break; 

        case 4:

            break;

        case 5:

            break;

        case 6:

            break;          
        }        
    }

Answer 1

I solve the problem just to use :

listView = (ListView) this.activity.findViewById(R.id.listView11);

to use this in line to solve the problem, until now i do not have problem.
