Android org.xmlpull.v1.XmlPullParserException：expected：START_TAG

Question

我是android开发的新手。我正在使用android studio来开发应用。 我知道有很多与之相关的问题，我调查了它们但我的问题仍然存在。以下是我研究过的解决方案。

1. link1
2. link2
3. link3

我清楚地调查了它们并与我的问题相匹配。但我仍然无法解决我的问题。

该应用很简单，会有editText个button和textView。用户应在id中输入editText，当点按button时，应显示相应的name。该按钮将使用webservice。

为此，我在SQL中创建了一些表格。并在webservice中创建了dotnet。

以下是我的网络服务

[WebMethod]

public string findContact(string eid)
{
    return getContact(eid);
}

public string getContact(string eid)
{

    SqlConnection conn;

    conn = ConnectionManager.GetConnection();
    conn.Open();

    SqlCommand newCmd = conn.CreateCommand();

    newCmd.CommandType = CommandType.Text;

    newCmd.CommandText = "Select Name from Users where Id=" + eid + "";

    SqlDataReader sdr = newCmd.ExecuteReader();

    String address = null;

    if(sdr.Read())
    {
        address = sdr.GetValue(0).ToString();
    }

    conn.Close();
    return address;
}

以下是我的清单文件

 <uses-permission android:name="android.permission.INTERNET"/>

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">
    <activity android:name=".MainActivity">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

以下是我的java代码

public class MainActivity extends AppCompatActivity {

/** Called when the activity is first created. */
private static final String SOAP_ACTION = "http://tempuri.org/findContact";
private static final String METHOD_NAME = "findContact";// webservice web method name
private static final String NAMESPACE = "http://tempuri.org/";
private static final String URL = "http://192.168.100.9:9698/WebService.asmx";

TextView textView;
Button button;
EditText editText;

String ID;
public static final String LOG_TAG = MainActivity.class.getSimpleName();
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);


    textView = (TextView)findViewById(R.id.webServ);
    button = (Button)findViewById(R.id.btnSubmit);

    if (android.os.Build.VERSION.SDK_INT > 9) {
        StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
        StrictMode.setThreadPolicy(policy);
    }

    button.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            SoapObject request = new SoapObject(NAMESPACE,METHOD_NAME);

            PropertyInfo propertyInfo = new PropertyInfo();
            propertyInfo.type = PropertyInfo.STRING_CLASS;
            propertyInfo.name = "eid";

            editText = (EditText)findViewById(R.id.enterID);

            ID = editText.getText().toString();

            request.addProperty(propertyInfo,ID);

            SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);

            envelope.dotNet = true;

            envelope.setOutputSoapObject(request);

            HttpTransportSE httpTransportSE = new HttpTransportSE(URL);
            httpTransportSE.debug = true;
            try
            {
                httpTransportSE.call(SOAP_ACTION,envelope);
                Object response = envelope.getResponse();
                textView.setText(response.toString());

            } catch (XmlPullParserException e) {

                textView.setText(e.toString() + " Or enter ID is not valid!");

                e.printStackTrace();
            } catch (IOException e) {
                textView.setText(e.toString() + " IOException Or enter ID is not valid!");
                e.printStackTrace();
            }

            String res = (httpTransportSE.responseDump).toString();
            Log.v(LOG_TAG, res);
        }
    });
}}

当我点击按钮时，我收到了波纹管错误。

点击httpTransportSE.call(SOAP_ACTION,envelope);

行

我在模拟器上测试它，下面是我的模拟器的屏幕截图



我还检查了我在网络浏览器中运行的Webservice，它工作正常。但它不在模拟器上。

任何帮助都将受到高度赞赏。
