如何使用Soap方法从android webservice方法中获取数据

import org.ksoap2.SoapEnvelope;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.HttpTransportSE;

public class MainActivity extends AppCompatActivity {
    private static final String NAMESPACE = "http://example.com/";
    private static final String URL = "http://example.com/Webservice.asmx";
    private static final String METHOD_NAME = "GetData";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // 创建SOAP请求
        SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);

        // 创建SOAP通信对象
        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
        envelope.setOutputSoapObject(request);

        // 创建HTTP传输对象
        HttpTransportSE transport = new HttpTransportSE(URL);

        try {
            // 调用Web服务方法并获取响应
            transport.call(NAMESPACE + METHOD_NAME, envelope);
            SoapObject response = (SoapObject) envelope.getResponse();

            // 处理响应数据
            String result = response.getPropertyAsString(0);
            Log.d("SOAP Response", result);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
