[英]Call ASP.NET web service using android using ksoap
我為呼叫Web服務創建了一個簡單的類
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();
}
}
這是我的“ Activity
點擊方法
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));
}
錯誤“不幸的是,App1已停止”。 請幫我..
這是由於Android 2.2之后出現NetworkOnMainThread異常,您無法在mainUi線程中運行長時間運行的操作(例如網絡訪問),因為mainUI線程用於加載Ui組件以使您的應用程序流暢高效。您應該使用AsynTask類來保持它脫離主線程
對於初學者來說,也是一種很好的實踐,將調用放入單獨的線程中。 我這樣做是這樣的:
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();
}
請注意,返回必須異步處理。
