android - 无法在android中的单独 TextView 中显示值

Question

我正在通过 Android 的 soap 方法使用 Web 服务。我在下一个屏幕上将来自该 Web 服务的值显示到两个单独的 TextView 中。

Web 服务在这里返回两个值。但我只能在下一屏幕的 TextView 中显示来自该 Web 服务的一个值。

但我需要在下一个屏幕上的两个单独的 TextView 框中显示这两个值.... 我怎样才能做到这一点？

建议请..

注意:- 该 Web 服务的输入值为 FromDate: 01/01/2012 和 ToDate: 07/07/2012

请找到我的引用资料

在这里检查一下......

public class Main_WB extends Activity {
EditText edt1, edt2;
// TextView txt_1;

Button btn;

ArrayList<String> result;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    edt1 = (EditText) findViewById(R.id.editText1);
    edt2 = (EditText) findViewById(R.id.editText2);
    btn = (Button) findViewById(R.id.button1);

    result = new ArrayList<String>();

    btn.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
            result.addAll(getTMSChart(edt1.getText().toString(), edt2.getText().toString()));

            Intent in = new Intent(getApplicationContext(), ResultActivity.class);

            in.putExtra("gotonextpageX", result.get(0));
            in.putExtra("gotonextpageY", result.get(1));

            startActivity(in);
        }
    });
}

private ArrayList<String> getTMSChart(String FromDate, String ToDate) {
    // txt_1 = (TextView)findViewById(R.id.textView1);

    System.setProperty("http.keepAlive", "false");
    SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);

    envelope.dotNet = true;

    String NAMESPACE = "http://tempuri.org/";
    String URL = "http://54.251.60.177/TMSOrdersService/TMSDetails.asmx";
    String METHOD = "GetTMSChart";

    SoapObject request = new SoapObject(NAMESPACE, METHOD);
    request.addProperty("FromDate", FromDate);
    request.addProperty("ToDate", ToDate);

    envelope.setOutputSoapObject(request);
    HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);

    String x = "", y = "";

    ArrayList<String> stringResult = new ArrayList<String>();

    try {
        androidHttpTransport.call(NAMESPACE + METHOD, envelope);
        SoapObject result = (SoapObject) envelope.bodyIn;
        SoapObject root = (SoapObject) ((SoapObject) (result).getProperty(0)).getProperty("NewDataSet");
        int tablesCount = root.getPropertyCount();

        for (int i = 0; i < tablesCount; i++) {
            SoapObject table = (SoapObject) root.getProperty(i);
            int propertyCount = table.getPropertyCount();

            for (int j = 0; j < propertyCount; j++) {

                stringResult.add(table.getPropertyAsString("Order_No").toString());
                stringResult.add(table.getPropertyAsString("Freight_Rate").toString());
            }
        }
    } catch (Exception e) {
    }

    return stringResult;

}
}

并且不要更改您的第二个类，这一定有效。
