我是新的android编程(第一个项目),我需要帮助,使我的代码工作... 好吧,所以我有一个方法,将调用web服务,并得到从那里的字符串。它正在对AVD(上2.2)调用.net web服务与Android使用ksoap2
下面是代码:
public void NewCall(int Position)
{
String SOAP_ACTION = "http://tempuri.org/";
String NAMESPACE = "http://tempuri.org/";
String METHOD_NAME = "";
String URL = "http://test.com/Service1.asmx?WSDL";
if(Position == 0)
{
SOAP_ACTION += "Method1";
METHOD_NAME = "Method1";
}
else if(Position == 1)
{
SOAP_ACTION += "Method2";
METHOD_NAME = "Method2";
}
else if(Position == 2)
{
SOAP_ACTION += "Method3";
METHOD_NAME = "Method3";
}
else if(Position == 3)
{
SOAP_ACTION += "Method4";
METHOD_NAME = "Method4";
}
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.setOutputSoapObject(request);
envelope.dotNet = true;
try
{
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
androidHttpTransport.call(SOAP_ACTION, envelope);
SoapObject result = (SoapObject)envelope.bodyIn;
if(result != null)
{
String textRez = result.getProperty(0).toString();
addRow(textRez); //method for inserting new row in the database
}
}
catch (Exception e)
{
e.printStackTrace();
}
}
但只要我阅读,你不能做到这一点在“主线程”与Android 3.0+和我看到一个解决方案,你可以用AsyncClass
来完成。关于这一点,我试图将我发现的例子与我的代码结合起来,但是它还没有给我结果呢... 我认为我需要将位置整数解析为AssyncClass,做所需的代码在doInBackground,然后我需要得到结果作为一个字符串。 我试图编写类似这样的东西,但它没有给我成功...
所以,如果你的某个人可以帮助/指导我解决这个问题,我将非常感激。
谢谢。
编辑:这是我试图用AsyncClass:
private class wsGet extends AsyncTask<String, Void, String>
{
@Override
protected String doInBackground(String... params) {
int Position = Integer.parseInt(params[0]);
String SOAP_ACTION = "http://tempuri.org/";
String NAMESPACE = "http://tempuri.org/";
String METHOD_NAME = "";
String URL = "http://test.com/Service1.asmx?WSDL";
if(Position == 0)
{
SOAP_ACTION += "Method1";
METHOD_NAME = "Method1";
}
else if(Position == 1)
{
SOAP_ACTION += "Method2";
METHOD_NAME = "Method2";
}
else if(Position == 2)
{
SOAP_ACTION += "Method3";
METHOD_NAME = "Method3";
}
else if(Position == 3)
{
SOAP_ACTION += "Method4";
METHOD_NAME = "Method4";
}
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.setOutputSoapObject(request);
envelope.dotNet = true;
try
{
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
androidHttpTransport.call(SOAP_ACTION, envelope);
SoapObject result = (SoapObject)envelope.bodyIn;
if(result != null)
{
tekstRez = result.getProperty(0).toString();
}
}
catch (Exception e)
{
e.printStackTrace();
}
return tekstRez;
}
然后调用这个我试过:
public void NewTenders(int Pos)
{
String Position = String.valueOf(Pos);
String[] params= {Position}; //to pass to doInBackground
//Pass your args array and the current activity to the AsyncTask
String tekst = "";
try {
tekst = new wsGet().execute(params).get();
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (ExecutionException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}addRow(tekst);
虽然,它没有为我工作。 ..
谢谢你的答案,是的,我知道。但如果我这样做,那么代码不适合我(没有做任何事)... – 4448932
你是如何做到这一点使用AsyncClass?发布代码。 –
