我使用WCF来托管.svc服务以从MySQL（在本地主机上）检索数据，我已经编写了一个类来使用Android上的服务，使用ksoap2版本3.1.1和IP 10.0.3.2进行Geny Motion访问本地主机
package com.example.mapdemo;
import java.io.IOException;
import java.net.Proxy;
import java.net.SocketTimeoutException;
import org.ksoap2.SoapEnvelope;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.HttpTransportSE;
public class KetNoiWebService {
private static final String NAMESPACE = "http://tempuri.org/";
private static final String MAIN_REQUEST_URL = "http://10.0.3.2:7741/ToaDoServiceHost.svc";
private static final String SOAP_ACTION = "http://tempuri.org/IToaDo/GetAllToaDo";
private static final SoapSerializationEnvelope getSoapSerializationEnvelope(
SoapObject request) {
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
SoapEnvelope.VER11);
envelope.dotNet = true;
envelope.implicitTypes = true;
envelope.setAddAdornments(false);
envelope.setOutputSoapObject(request);
return envelope;
}
private static final HttpTransportSE getHttpTransportSE() {
HttpTransportSE ht = new HttpTransportSE(MAIN_REQUEST_URL, 60000);
return ht;
}
public static int getAllToaDoTuWebService() {
int count = 1;
String methodname = "GetAllToaDo";
SoapObject request = new SoapObject(NAMESPACE, methodname);
SoapSerializationEnvelope envelope = getSoapSerializationEnvelope(request);
HttpTransportSE ht = getHttpTransportSE();
try {
ht.call(SOAP_ACTION, envelope);
SoapObject resultsString = (SoapObject) envelope
.bodyIn;
SoapObject result = (SoapObject)resultsString.getProperty(0);
count = result.getPropertyCount();
} catch (SocketTimeoutException t) {
t.printStackTrace();
} catch (IOException i) {
i.printStackTrace();
} catch (Exception q) {
q.printStackTrace();

return count;

}

答案 0 :(得分：0)
您需要使用AsyncTask来执行所有网络操作。
您的网络操作可能会花费大量时间，如果在主UI线程上完成，UI将无法响应。如果您的用户界面长时间冻结，应用程序可能会被操作系统杀死。
因此，Android 4+强制要求使用后台线程来执行网络操作。
使用 doInBackground() 将代码放在 execute() 和所有AsyncTask中进行网络活动。
以下是您的AsyncTask的样子：
private class SendMail extends AsyncTask<String, Integer, Void> {
protected void doInBackground() {
sendEmail();
}
protected void onProgressUpdate() {
//called when the background task makes any progress
}
protected void onPreExecute() {
//called before doInBackground() is started
}
protected void onPostExecute() {
//called after doInBackground() has finished
}
}
您可以使用 new SendMail().execute("");
答案 1 :(得分：0)
您不应该在主线程（UI线程）中调用Web服务。 您应该使用Services或AsyncTask来执行相同的操作
答案 2 :(得分：0)
class DoInBack extends AsyncTask<String, Void, String> {
@Override
protected void onPreExecute() {
super.onPreExecute();
}
@Override
protected String doInBackground(String... urls) {
String res = "";
try {
res=KetNoiWebService.getAllToaDoTuWebService();
} catch (Exception e) {
e.printStackTrace();
}
return res;
}
@Override
protected void onPostExecute(String result) {
Toast.makeText(MainActivity.this, ""+result, 1).show();
((TextView)findViewById(R.id.webservicecount))
.setText(result);
}
}
并在onCreate中写下以下行
new DoInBack().execute("");
