我想在我的Android应用中使用.net网络服务。我使用asynctask向Web服务发送请求。但请求没有正确获取价值。我在许多Android应用程序中使用此结构,我从来没有像这样的错误。有什么问题?
我有权(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

@Override

return items;

编辑:我编辑了代码而我没有使用对话框。请不要写关于对话的答案。对话框不会出现问题。

您需要在ProgressDialog
内而不是在班级初始化onPreExecute
:
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();
}

该错误是因为您的AsynTask
上发生了另一个/上一个错误,并且此活动绑定的dialog
未被解除,它会激活您发布的例外。
顺便说一下,如果要在活动被销毁时停止AsynTask
,请记住
onDestroy
处的asyntask。AsynTask
,请覆盖onCancelled
功能,并检查doinBackground
上的条件是否完成
尽快完成任务。onCancelled
处也会关闭对话框。否则,您的活动可以在onPostExecute之前销毁,并且将在该函数上激活异常。
可以通过调用cancel(boolean)随时取消任务。调用此方法将导致后续调用isCancelled()返回true。调用此方法后,将在doInBackground(Object [])返回后调用onCancelled(Object)而不是onPostExecute(Object)。为确保尽快取消任务,应始终定期从doInBackground(Object [])检查isCancelled()的返回值(如果可能)(例如在循环内)。
答案 2 :(得分:1)
实际问题在GetAllItems()方法中,它正在生成活动即将完成的异常,之后您尝试显示进度对话框做一件事将try catch放入GetAllItems()并尝试在doInBackground中运行此代码。
