如何從Web服務設置列表視圖陣列

我是Android新手。我正在嘗試從Web服務的數組列表中填充列表視圖。我一直沒有找到任何使用數組到listview的在線教程。我令牌「最終」，無效的類型得到一個語法錯誤如何從Web服務設置列表視圖陣列

這裏是我的Java代碼：

public class LocationFragment extends Fragment { 

    ListView tv; 

    public LocationFragment() { 
    } 

    private String TAG = "Vik"; 

    @Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 

     View rootView = inflater.inflate(R.layout.fragment_location, container, false); 
     tv = (ListView) rootView.findViewById(R.id.listView1); 
     AsyncCallWS task = new AsyncCallWS(); 
     task.execute(); 
     return rootView; 
    } 

    private class AsyncCallWS extends AsyncTask<Void, Void, Void> { 
     @Override 
     protected Void doInBackground(Void... params) { 
      Log.i(TAG, "doInBackground"); 
      location(); 
      return null; 
     } 

     @Override 
     protected void onPostExecute(Void result) { 
      Log.i(TAG, "onPostExecute"); 
     } 

     @Override 
     protected void onPreExecute() { 
      Log.i(TAG, "onPreExecute"); 
     } 

     @Override 
     protected void onProgressUpdate(Void... values) { 
      Log.i(TAG, "onProgressUpdate"); 
     } 

    } 

    public void location() 
    { 
     String SOAP_ACTION = "http://example.com/getlocations"; 
     String METHOD_NAME = "getlocations"; 
     String NAMESPACE = "http://example.com/"; 
     String URL = "http://localhost/example/Service.asmx"; 

     try { 
      SoapObject Request = new SoapObject(NAMESPACE, METHOD_NAME); 
      Request.addProperty("get locations", "null"); 

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

      HttpTransportSE transport= new HttpTransportSE(URL); 

      transport.call(SOAP_ACTION, envelope); 

      Object result=(Object)envelope.getResponse(); 

      final results = (String[]) result; 


      getActivity().runOnUiThread(new Runnable() { 
       @Override 
       public void run() { 
        // This code will always run on the UI thread, therefore is safe to modify UI elements. 

        ArrayAdapter<MyObject> adapter = new ArrayAdapter<MyObject>(this, 
          android.R.layout.simple_list_item_1, results); 

        tv.setAdapter(adapter); 
       } 
      }); 
     } 
     catch(Exception ex) { 
      Log.e(TAG, "Error: " + ex.getMessage()); 
     } 
    } 
}

而且，這裏是我的web服務的任何幫助將不勝感激。

[WebMethod] 
public string[] getlocations() 
{ 
    SqlConnection cn = new SqlConnection("Data Source=DEV-SQL1;Initial Catalog=portal;User Id=wstest;Password=wstest;"); 
    List<string> locations = new List<string>(); 
    cn.Open(); 
    string sqlquery = string.Format("SELECT LocationName FROM ts_locations where CompanyID = '130' ORDER by LocationName"); 
    SqlCommand com = new SqlCommand(sqlquery, cn); 
    SqlDataReader sqlReader = com.ExecuteReader(); 
    while (sqlReader.Read()) 
    { 
     locations.Add(sqlReader.GetString(0)); 
    } 
    cn.Close(); 
    return locations.ToArray(); 
}

看看this tutorial這裏我所說的JSON Web服務填充響應數據到ArrayList和與ArrayList的填充ListView

聚焦在這條線的位置：

ArrayAdapter<String> adapter =new ArrayAdapter<String>(getBaseContext(), android.R.layout.simple_list_item_1,titleCollection);

在哪裏titleCollection是一個ArrayList<String>
