我想在我的 android 应用程序中使用 .net 网络服务。我使用 asynctask 向 Web 服务发送请求。但是请求没有正确地取值。我在许多 android 应用程序中使用了这种结构,但我从来没有遇到过这样的错误。问题是什么?
我有权限(互联网)。命名空间和方法名称为真。
public class MainActivity extends Activity {
private static final String NAMESPACE = "http://tempuri.org/";
private static final String URL = "http://service.melihmucuk.com/ShopArWS.asmx";
private String[][] items;
private String[][] GetAllItems(){
SoapObject request = new SoapObject(NAMESPACE, "GetAllItem");//faulty line
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.dotNet = true;
envelope.setOutputSoapObject(request);
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
androidHttpTransport.debug = true;
try {
androidHttpTransport.call("http://tempuri.org/GetAllItem", envelope);
SoapObject response = (SoapObject) envelope.getResponse();
items[0] = new String[response.getPropertyCount()]; //item_id
items[1] = new String[response.getPropertyCount()]; //price
items[2] = new String[response.getPropertyCount()]; //title
items[3] = new String[response.getPropertyCount()]; //desc
for(int i=0;i<response.getPropertyCount();i++){
Object property = response.getProperty(i);
if(property instanceof SoapObject){
SoapObject item = (SoapObject) property;
String item_id = item.getProperty("item_id").toString();
String price = item.getProperty("price").toString();
String title = item.getProperty("title").toString();
String desc = item.getProperty("desc").toString();
items[0][i] = item_id;
items[1][i] = price;
items[2][i] = title;
items[3][i] = desc;
}
}
}
catch (Exception e) {
e.printStackTrace();
}
return items;
}
public class GetAllItemsAS extends AsyncTask<String,String,String[][]>{
@Override
protected void onPreExecute() {
}
@Override
protected String[][] doInBackground(String... params) {
GetAllItems();
return items;
}
protected void onPostExecute(String[][] items){
ASFinish();
}
}
public void ASFinish(){
ListView liste = (ListView)findViewById(R.id.listView1);
ListArrayAdapter adapter = new ListArrayAdapter(MainActivity.this,items[0],items[1],items[2],items[3]);
liste.setAdapter(adapter);
}
@Override
