我有一個webservice，它返回對象的數組列表。 我想在我的android代碼中訪問這個對象的數組列表。我該怎麼做？ 我的web服務是訪問Webservice返回值

並返回到Android我的java類是
package com.example.chillum;
import android.net.http.AndroidHttpClient;
import com.example.chillum.Utils;
import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.util.EntityUtils;
import java.util.ArrayList;
public class HttpManager {
public static ArrayList<myClass> getdata(String uri)
{
AndroidHttpClient client=AndroidHttpClient.newInstance("AndroidAgent");
HttpGet request=new HttpGet(uri);
HttpResponse response;
try{
response=client.execute(request);
return //what?;
}
catch(Exception e)
{
e.printStackTrace();
return null;
}
finally
{
client.close();
}
}
}
，我應該什麼樣的回報，使得我得到的數組列表？ 這個方法返回到一個異步任務，其他的操作是用arraylist完成的。 請幫忙。
