我为调用Web服务创建了一个简单的类
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://localhost:41614/Service1.asmx";
public CallSoap()
{
}
public String Call(int a,int b)
{
SoapObject request = new SoapObject(WSDL_TARGET_NAMESPACE,OPERATION_NAME);
request.addProperty("a",a);
request.addProperty("b",b);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.dotNet = true;
envelope.setOutputSoapObject(request);
HttpTransport httpTransport = new HttpTransport(SOAP_ADDRESS);
Object response=null;
try
{
httpTransport.call(SOAP_ACTION, envelope);
response = envelope.getResponse();
}
catch (Exception exception)
{
response=exception.toString();
}
return response.toString();
}
}
这是我的Activity
点击方法
public void clickData(View v)
{
//Intent intent = new Intent(this, DisplayMessageActivity.class);
EditText et=(EditText) findViewById(R.id.editText1);
EditText et2=(EditText) findViewById(R.id.editText2);
TextView tv=(TextView) findViewById(R.id.textView1);
int a=Integer.parseInt(et.getText().toString());
int b=Integer.parseInt(et2.getText().toString());
CallSoap cs=new CallSoap();
tv.setText(cs.Call(a, b));
}
有一个错误“不幸的是App1已经sttoped”。请帮帮我..

这是由于android 2.2之后的NetworkOnMainThread异常你无法在mainUi Thread中运行长时间运行的操作,如网络访问,因为mainUI线程用于加载Ui组件,使你的应用程序流畅高效。你应该使用AsynTask类让它远离主线程

对于初学者而言,作为一种非常好的练习,请将呼叫转换为单独的线程。 我是这样做的:
public void call() {
Log.d("TAG", "Started call");
new Thread(new Runnable()
{
public void run() {
Looper.prepare();
/** UI stuff/ This runs on the main thread to update the UI. This can be used for displaying something like "please wait */
AppPrefFragment.updateSyncJobsNumber(AppPrefFragment.JOB_START);
if (AppPrefActivity.context != null) {
((Activity) AppPrefActivity.context).runOnUiThread(new Runnable()
{
public void run() {
//AppPrefFragment.setSyncPreferenceStatusShowingOngoingJobs();
... show "please wait"
}
});
}
/** Actual stuff that you want to do */
... the HttpCall or SOAP etc
}
}).start();
}
请注意,必须异步处理返回。
