【问题描述】:
我想在 android 中调用 asp.net 网络服务。 (那个网络服务很简单,把两个整数相加并返回结果。)
我的问题是:当我运行我的应用程序并单击按钮时(用于从文本字段中提供数字并通过 Web 服务求和并通过 AlertDialog 显示结果) 应用程序被冻结在一种状态,因为它不起作用。这是我在该状态下的应用截图(点击按钮后): freeze in this status! :-(
在很长一段时间后显示这个按摩: “Soap 没有响应。关闭它是什么?”。
请帮帮我!
这在我的网络服务代码中:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Services;
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
// [System.Web.Script.Services.ScriptService]
public class Service : System.Web.Services.WebService
{
public Service () {
//Uncomment the following line if using designed components
//InitializeComponent();
}
[WebMethod]
public int add (int a, int b) {
return a + b;
}
}
这是CallSoap,这个类调用我的网络服务:
import org.ksoap2.SoapEnvelope;
import org.ksoap2.serialization.PropertyInfo;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.HttpTransportSE;
public class CallSoap
{
public final String SOAP_ACTION = "http://tempuri.org/add";
public final String OPERATION_NAME = "add";
public final String WSDL_TARGET_NAMESPACE = "http://tempuri.org/";
public final String SOAP_ADDRESS = "http://s1.azarindk.co.ir/service.asmx";
public CallSoap()
{
}
public String Call(int a,int b)
{
SoapObject request = new SoapObject(WSDL_TARGET_NAMESPACE,OPERATION_NAME);
//PropertyInfo pi =new PropertyInfo();
request.addProperty("a", Integer.valueOf(a));
request.addProperty("b", Integer.valueOf(b));
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
SoapEnvelope.VER11);
envelope.dotNet = true;
envelope.setOutputSoapObject(request);
HttpTransportSE httpTransport = new HttpTransportSE(SOAP_ADDRESS);
Object response=null;
try
{
httpTransport.call(SOAP_ACTION, envelope);
response = envelope.getResponse();
}
catch (Exception exception)
{
response=exception.toString();
}
System.out.print(response.toString());
return response.toString();
}
}
这是一个在主Activity中调用CallSoap的线程:
package com.example.soap;
public class Caller extends Thread
{
public CallSoap cs;
public int a,b;
public void run(){
try{
cs=new CallSoap();
String resp=cs.Call(a, b);
MainActivity.rslt=resp;
}catch(Exception ex)
{MainActivity.rslt=ex.toString();
}
}
}
这是我的主要活动:
package com.example.soap;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.app.Activity;
import android.app.AlertDialog;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;
public class MainActivity extends ActionBarActivity {
public static String rslt="";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button b1=(Button)findViewById(R.id.button1);
final AlertDialog ad=new AlertDialog.Builder(this).create();
b1.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
CallSoap cs=new CallSoap();
try
{
EditText ed1=(EditText)findViewById(R.id.editText1);
EditText ed2=(EditText)findViewById(R.id.editText2);
int a=Integer.parseInt(ed1.getText().toString());
int b=Integer.parseInt(ed2.getText().toString());
rslt="START";
Caller c=new Caller();
c.a=a;
c.b=b;
// c.ad=ad;
c.join();
c.start();
while(rslt=="START") {
try {
Thread.sleep(10);
}catch(Exception ex) {
}
}
ad.setTitle("RESULT OF ADD of "+a+" and "+b);
ad.setMessage(rslt);
}catch(Exception ex) {
ad.setTitle("Error!"); ad.setMessage(ex.toString());
}
ad.show();
} });
}
}
