Android AsyncTask SoapObject请求问题
作者：互联网
我想在我的Android应用程序中使用.net Web服务.我通过使用asynctask将请求发送到Web服务.但是请求的价值不正确.我在许多android应用程序中使用了这种结构,但从未遇到这样的错误.问题是什么？
我有权限(互联网).命名空间和方法名称为true.
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
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
items = new String[4][0];
new GetAllItemsAS().execute();
}
}

编辑：我编辑了代码,但不使用对话框.请不要写关于对话框的答案.对话框不会出现问题.
解决方法:
您将需要在onPreExecute而不是在类级别初始化ProgressDialog：
private ProgressDialog dialog; //declare here
@Override
protected void onPreExecute() {
dialog = new ProgressDialog(MainActivity.this); //<< initialize here
dialog.setMessage("Loading...");
dialog.show();
}
//.....
protected void onPostExecute(String[][] items){
ASFinish();
if(null !=dialog)
if(dialog.isShowing())
dialog.dismiss();
}
