我必须使用 Web 服务数据（XML 解析）填充微调器。它包含两个属性，例如“ID”和“Name”。代码如下：

    try {

            ArrayList<String> listdata = new ArrayList<String>();

            URL url = new URL(
                    "http://10.0.2.2/WebService/Service.asmx/GetService");

                DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
                DocumentBuilder db = dbf.newDocumentBuilder();
                Document doc = db.parse(new InputSource(url.openStream()));
                doc.getDocumentElement().normalize();

                NodeList nodeList = doc.getElementsByTagName("Table");




                    for (int i = 0; i < nodeList.getLength(); i++) {

                        Node node = nodeList.item(i);



                        Element providerID = (Element) node;
                        NodeList providerIDlist = providerID.getElementsByTagName("id");
                        Element providerIDelement = (Element) providerIDlist.item(0);
                        providerIDlist = providerIDelement.getChildNodes();

                         MProviderIDL = providerIDlist.item(0).getNodeValue();
                         //mprovider.put("MproviderID", MProviderIDL.toString());
                        listdata.add(MProviderIDL);


Element providerName = (Element) node;
                        NodeList providerNamelist = providerName.getElementsByTagName("value");
                        Element prividerNameElement = (Element) providerNamelist.item(0);
                        providerNamelist = prividerNameElement.getChildNodes();
                        //AddImg[i].setTag(((Node) AdvImglist.item(0)).getNodeValue());
                        MProviderNameL = providerNamelist.item(0).getNodeValue();
                        //mprovider.put("MproviderName", MProviderNameL.toString());
                        listdata.add(MProviderNameL);





                        }

                    Spinner spinMProvider=(Spinner)findViewById(R.id.spinMProvider);

                    ArrayAdapter < String > adapter = new ArrayAdapter < String > (this,
                            android.R.layout.simple_list_item_1,listdata);
                    adapter.setDropDownViewResource( android.R.layout.simple_spinner_dropdown_item );
                    spinMobileProvider.setAdapter(adapter);


        }

        catch (MalformedURLException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (ParserConfigurationException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (SAXException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

将值发送到数据库..

private void Send(View v,String Url) {

        HttpPost postMethod=new HttpPost(Url); 
        List<NameValuePair> regParams=new ArrayList<NameValuePair>();
         DefaultHttpClient hc=new DefaultHttpClient();  



        regParams.add(new BasicNameValuePair("_fname",edtFname.getText().toString()));


        regParams.add(new BasicNameValuePair("_lname",edtLname.getText().toString()));


        regParams.add(new BasicNameValuePair("_email",edtEmail.getText().toString()));


        regParams.add(new BasicNameValuePair("_password",edtPassword.getText().toString()));


        regParams.add(new BasicNameValuePair("_address",edtAddress.getText().toString()));


        regParams.add(new BasicNameValuePair("Provider", Integer.toString(spinMProvider.getSelectedItemPosition())));

我的 XML 数据...

<Table diffgr:id="Table4" msdata:rowOrder="3">
<id>11</id>
<value>Cellular South</value>
</Table>
<Table diffgr:id="Table5" msdata:rowOrder="4">
<id>10</id>
<value>Cricket</value>
</Table>
<Table diffgr:id="Table6" msdata:rowOrder="5">
<id>4</id>
<value>Sprint NexTel</value>
</Table>

和这样的输出......

我必须在微调器列表中显示名称并将特定的 id 传递给数据库。如何获取 ID 到文本的后端？

将 id 和 spinner 值作为一组对象放在数组列表中

Class spinnerObj {

String id;
String spinnervalue;
}

Arraylist<spinnerObj> sp = new Arraylist<spinnerObj>():

现在用这个 arraylist sppinnervalue 中的值填充你的微调器；

在微调器的 onValueChange 方法中，您将获得与您添加的顺序相同的位置，然后您可以调用 sp.get(position).getID() 您将获得与之关联的 id微调器值。
