自动完成文本视图数据从 ksoap web 服务获取，使用搜索图标 Onclick 请求和异步任务

Question

我们如何从 soap 网络服务中获取数据，显示在 Android Autocompletetextview 搜索建议中，使用 Onclick 搜索按钮。

Answer 1

EditText 未显示建议。

AutoCompleteTextView 在 editText 中提供建议。

首先你需要从服务器解析数据。然后使用该数据制作适配器并在 AutoCompleteTextView 中设置。

public void getSignupdata(String SearchValue, String CityLocation) 
    {
        // Create request
        SoapObject request = new SoapObject(NAMESPACE2, METHOD_NAME2);

        PropertyInfo pi3 = new PropertyInfo();
        pi3.setName("search");
        pi3.setValue(SearchValue);// get the string that is to be sent to the webservice
        pi3.setType(String.class);
        request.addProperty(pi3);

        PropertyInfo pi4 = new PropertyInfo();
        pi4.setName("City");
        pi4.setValue(CityLocation);// get the string that is to be sent to the webservice
        pi4.setType(String.class);
        request.addProperty(pi4);

        // Create envelope
        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
        envelope.dotNet = true;
        // Set output SOAP object
        envelope.setOutputSoapObject(request);
        // Create HTTP call object
        HttpTransportSE androidHttpTransport = new HttpTransportSE(URL2);

        try {
            // Invole web service
            androidHttpTransport.call(SOAP_ACTION2, envelope);
            // Get the response
            SoapPrimitive response = (SoapPrimitive) envelope.getResponse();

            if ((response.toString()).contains("{")) 
            {
                // JSONArray jr = new JSONArray(response);
                SoapObject rep = (SoapObject) envelope.bodyIn;
                JSONArray jr = new JSONArray(rep.getPropertyAsString(0));
                for (int i = 0; i < jr.length(); i++) {
                    JSONObject jb = (JSONObject) jr.get(i);



                       ServiceCenterName = jb.getString("CenterName");



                        String strArray[] = ServiceCenterName.split(" ");

                System.out.println("String converted to String array");

                //print elements of String array
                for(int i=0; i < strArray.length; i++)
                {
                        System.out.println(strArray[i]);
                }

            ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,android.R.layout.select_dialog_singlechoice, strArray);

            SearchEdittext.setThreshold(1);
            SearchEdittext.setAdapter(adapter)


                }
            } 
            else
            {
                Status_Response_FindStores_Landing = response.toString();
            }

        } catch (Exception e) {
            Log.i(TAG2, "Error in catch");
            e.printStackTrace();
        }

    }
