表达式的类型必须是数组类型，但它解析为 SoapObject

Question

我正在尝试将 aspx 网络服务返回的数组打印到 android TextView 上。我实际上可以使用以下 android 和 C# aspx 代码读取文本视图中的数据。但问题是，当我以以下格式打印输出时：

anyType{string="Shean";string="Ya";string="Hey";} 而不是 申雅&嘿

所以我决定读取数组如下：

for (int i = 0; i < intPropertyCount; i++) {
                SoapObject responseChild = (SoapObject) response.getProperty(i);
                int lengthOfResponseChild = responseChild.getPropertyCount();
                for (int j = 0; j < lengthOfResponseChild; j++) {
                    //Error Highlight is as responseChild[j]
                    result.setText(responseChild[j].toString());

                }
                //Used this line and prints output on a textView as anyType{string="Shean";string="Ya";string="Hey";}
                //result.setText(responseChild.toString());
            }

但是在

处突出显示了一个错误

result.setText(responseChild[j].toString());

声明The type of the expression must be an array type but it resolved to SoapObject

我的完整android代码如下：

package com.example.fp1_webservicedropdown;

import android.app.Activity;
import android.os.Bundle;
import android.widget.Spinner;
import android.widget.TextView;
import org.ksoap2.*;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.*;

public class MainActivity extends Activity {
    TextView result;
    Spinner spinnerC;

    @Override
    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        spinnerC = (Spinner) findViewById(R.id.spinner1);
        result = (TextView) findViewById(R.id.textView2);

        final String NAMESPACE = "http://sample.com/";
        final String METHOD_NAME = "GetCustomerList";
        final String SOAP_ACTION = "http://sample.com/GetCustomerList";
        final String URL = "http://myLocalIP/HelloWorldNew/Service1.asmx";

        SoapObject Request = new SoapObject(NAMESPACE, METHOD_NAME);

        SoapSerializationEnvelope soapEnvelope = new SoapSerializationEnvelope(
                SoapEnvelope.VER11);
        soapEnvelope.dotNet = true;
        soapEnvelope.setOutputSoapObject(Request);
        AndroidHttpTransport aht = new AndroidHttpTransport(URL);

        try {

            aht.call(SOAP_ACTION, soapEnvelope);
            SoapObject response = (SoapObject) soapEnvelope.bodyIn;
            int intPropertyCount = response.getPropertyCount();

            for (int i = 0; i < intPropertyCount; i++) {
                SoapObject responseChild = (SoapObject) response.getProperty(i);
                int lengthOfResponseChild = responseChild.getPropertyCount();
                for (int j = 0; j < lengthOfResponseChild; j++) {
                    //Error Highlight is as responseChild[j]
                    result.setText(responseChild[j].toString());

                }
                //Used this line and prints output on a textView as anyType{string="Shean";string="Ya";string="Hey";}
                //result.setText(responseChild.toString());
            }


        } catch (Exception e) {

            e.printStackTrace();

        }
    }
}

我完整的asp web方法代码如下：

 [WebMethod]
    public string[] GetCustomerList()
    {
        //substitute code to actually populate the array with the dataset data
        string[] personIds = { "Shean", "Ya", "Hey" };
        return personIds;
    }

responseChild 是 SoapObject 的一个实例，但您正在尝试对其使用数组访问语法。

如果您尝试遍历 responseChild 中的属性，SoapObject 有方法 getProperty(int index)

使用它，您的循环将如下所示：

for (int j = 0; j < lengthOfResponseChild; j++) {
  result.setText(responseChild.getProperty(j).toString());
}
