如何使用 SOAP 在 android 中解析 JSON？

Question

我正在尝试使用 Android 中的 SOAP 解析来自 Web 服务的 JSON 数据。我的数据显示在调试器中，但不在应用程序中。我正在使用 SOAP，因为在我的 WebService JSON 数据中是 XML 标记。当我在 MainActivity 中调用 JSONOBJECT 时，它会引发异常并且不要进入 for 循环。它通常会给我错误，即字符串无法转换为 JSONOBJECT 或整数无法转换为 JSONOBJECT。我想在一个列表中显示所有数据，我正在使用另一个类 TableAdapter 并且我还使用一个名为 Table 的模型，其中调用了 getter 和 setter 函数。告诉我该怎么做。

这是我的 MainActivity

 public class MainActivity extends AppCompatActivity implements MyInterface
{

ListView List;
TableAdapter adapter;
ArrayList<Table> tableArrayList;

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

    List = (ListView) findViewById(R.id.list);
    tableArrayList = new ArrayList<Table>();

    String SOAP_ACTION = "http://tempuri.org/xxxx";
    String OPERATION_NAME = "xxxx";

    WebServiceHandler webServiceHandler = new WebServiceHandler(MainActivity.this);
    webServiceHandler.setValues(SOAP_ACTION, OPERATION_NAME);
    try
    {
        webServiceHandler.executeProcedure();
    }
    catch (Exception e)
    {
        Toast.makeText(this, "cant connect", Toast.LENGTH_SHORT).show();
    }
}
@Override
public void StartedRequest()
{

}



   @Override
    public void CodeFinished(String methodName, Object Data) {
//        String str = Data.toString();
//        if (str != null)
        {
            try
            {
                JSONObject jsonObject = new JSONObject(String.valueOf(data));
                JSONArray jsonArray = jsonObject.getJSONArray("Table");
                for( int i=0; i < jsonArray.length(); i++ )
                {
                    Table table = new Table();
                    JSONObject jsonObject1 = jsonArray.getJSONObject(i);
                    table.setRequestID(jsonObject1.getInt("Request_ID"));
                    table.setOwnerID(jsonObject1.getInt("Owner_ID"));
                    table.setCustomerID(jsonObject1.getInt("Customer_ID"));
                    table.setAssetName(jsonObject1.getString("AssetName"));
                    table.setAddress(jsonObject1.getString("Address"));
                    table.setDateTime(jsonObject1.getString("DateTime"));
                    table.setOwnerName(jsonObject1.getString("OwnerName"));
                    table.setCustomerName(jsonObject1.getString("CustomerName"));

                    tableArrayList.add(table);
                }
            }
            catch (JSONException e)
            {
                e.printStackTrace();
            }
            TableAdapter adapter = new TableAdapter(getApplicationContext(), R.layout.row, tableArrayList);
            List.setAdapter(adapter);
        }
    }


@Override
    public void CodeFinishedWithException(Exception ex, String exp)
    {

    }

    @Override
    public void CodeEndedRequest()
    {

    }
}

这是代码

我面临的问题。调试器不要进入这个for循环。

 @Override
    public void CodeFinished(String methodName, Object Data) {
//        String str = Data.toString();
//        if (str != null)
        {
            try
            {
                JSONObject jsonObject = new JSONObject(String.valueOf(data));
                JSONArray jsonArray = jsonObject.getJSONArray("Table");
                for( int i=0; i < jsonArray.length(); i++ )
                {
                    Table table = new Table();
                    JSONObject jsonObject1 = jsonArray.getJSONObject(i);
                    table.setRequestID(jsonObject1.getInt("Request_ID"));
                    table.setOwnerID(jsonObject1.getInt("Owner_ID"));
                    table.setCustomerID(jsonObject1.getInt("Customer_ID"));
                    table.setAssetName(jsonObject1.getString("AssetName"));
                    table.setAddress(jsonObject1.getString("Address"));
                    table.setDateTime(jsonObject1.getString("DateTime"));
                    table.setOwnerName(jsonObject1.getString("OwnerName"));
                    table.setCustomerName(jsonObject1.getString("CustomerName"));

                    tableArrayList.add(table);
                }
            }
            catch (JSONException e)
            {
                e.printStackTrace();
            }
            TableAdapter adapter = new TableAdapter(getApplicationContext(), R.layout.row, tableArrayList);
            List.setAdapter(adapter);
        }

这是我的网络服务

Answer 1

public void CodeFinished(String methodName, Object Data) 

这里的数据不是字符串对象。这可能会导致问题。 这可以是一个普通的 java 对象 {可能是 pojo} 类，您不能将其转换为字符串。

Answer 2

试试这个：

SoapPrimitive resultSoapPrimitive;
resultSoapPrimitive = (SoapPrimitive) Data.getResponse();
if (resultSoapPrimitive != null) {
    result = resultSoapPrimitive.toString();
}
