Android connects to webservice (using the jar package provided by Google) and androidwebservice

Android development, need to connect webservice, before you want to use Google provided jar package: http://pan.baidu.com/s/1hqMTUHe

Download it and paste it to the libs Folder:

There are many similar methods on the Internet. I tried a lot but failed. I finally found that the jar package I downloaded was faulty, which caused me to stay stuck.

First, add the network permission:

<uses-permission android:name="android.permission.INTERNET"/>

This is all the code, including obtaining data from the remote webservice and displaying it with ListView:

Package com. example. webservice; import java. io. IOException; import java. util. arrayList; import java. util. list; import org. ksoap2.SoapEnvelope; import org. ksoap2.SoapFault; import org. ksoap2.serialization. soapObject; import org. ksoap2.serialization. soapSerializationEnvelope; import org. ksoap2.transport. httpTransportSE; import org. xmlpull. v1.XmlPullParserException; import android. OS. bundle; import android. app. A Ctivity; import android. view. menu; import android. view. view; import android. widget. adapterView; import android. widget. adapterView. onItemClickListener; import android. widget. arrayAdapter; import android. widget. listAdapter; import android. widget. listView; import android. widget. toast; public class MainActivity extends Activity {// nameSpace String nameSpace = "http://tempuri.org/"; // call method String methodName = "selectSt UAll "; // method name for webservice: String endPoint =" http: // 10.0.2.2: 8011/WebService. asmx? Wsdl "; // link to local test complete String soapAction =" http://tempuri.org/selectStuAll "; // namespace and call method name private ListView listview; private ListAdapter adapter; protected void onCreate (Bundle savedInstanceState) {super. onCreate (savedInstanceState); setContentView (R. layout. activity_main); listview = (ListView) findViewById (R. id. listView1); adapter = new ArrayAdapter <String> (MainActivity. this, android. r. layout. simple_list_ite M_1, getsource (); listview. setAdapter (adapter); listview. setOnItemClickListener (new OnItemClickListener () {@ Override public void onItemClick (AdapterView <?> Arg0, View arg1, int arg2, long arg3) {// TODO automatically generated method stub Toast. makeText (MainActivity. this, ">" + adapter. getItem (arg2), 1 ). show () ;}}) ;}public List <String> getsource () {List <String> list = new ArrayList <String> (); // instantiate SoapObject object SoapObject request = new SoapObject (nameSpace, methodName); // Step 2: Set the call method parameter/* request. addProperty ("username", "1"); request. addProperty ("password", "2"); request. addProperty ("tel", "3"); * // obtain the serialized Envelope SoapSerializationEnvelope envelope = new SoapSerializationEnvelope (SoapEnvelope. VER12); envelope. bodyOut = request; envelope. dotNet = true; HttpTransportSE transport = new HttpTransportSE (endPoint); try {transport. call (soapAction, envelope);} catch (IOException e) {// catch Block e automatically generated by TODO. printStackTrace ();} catch (XmlPullParserException e) {// catch Block e automatically generated by TODO. printStackTrace ();} SoapObject result = null; try {result = (SoapObject) envelope. getResponse ();} catch (SoapFault e) {// catch Block e automatically generated by TODO. printStackTrace ();} int count = result. getPropertyCount (); for (int index = 1; index <count; index = index + 3) {list. add (result. getProperty (index ). toString () ;}return list ;}}

In this case, I will help you solve the problem if there is a problem with this method.
