您好,我已经开发了一个 Android 应用程序。

该应用程序的目的是从 mysql 数据库中检索数据并在 android 设备中显示。

这是我的安卓代码:

public class RetailerActivity extends Activity {
private final String NAMESPACE = "http://ws.testprops.com";
private final String URL = "http://krish.jelastic.servint.net/Retrieve/services/Fetch?wsdl";
private final String SOAP_ACTION = "http://ws.testprops.com/customerData";
private final String METHOD_NAME = "customerData";
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.setOutputSoapObject(request);

HttpTransportSE ht = new HttpTransportSE(URL);
try {
ht.call(SOAP_ACTION, envelope);
SoapPrimitive response = (SoapPrimitive)envelope.getResponse();
SoapPrimitive s = response;
String str = s.toString();
String resultArr[] = str.split("&");//Result string will split & store in an array

TextView tv = new TextView(this);

for(int i = 0; i<resultArr.length;i++){
tv.append(resultArr[i]+"\n\n");
}
setContentView(tv);

} catch (Exception e) {
e.printStackTrace();
}
}}

如果我必须运行该应用程序意味着只显示黑屏。它花费了将近 1 小时的时间太长我的 android 控制台窗口也出现以下错误:

请帮助我。我该如何解决这个错误。

最佳答案

改变

SoapPrimitive response = (SoapPrimitive)envelope.getResponse();

SoapObject response = (SoapObject)envelope.getResponse();
