当我试图联系网络服务并向他们发送华氏温度时，它会为我将它们转换为 celsium，但它会返回：

FahrenheitToCelsiusResponse{FahrenheitToCelsiusResult = ERROR;}

为 EditTexts 创建一个全局引用

喜欢

public EditText myEditText;

然后在onCreate中，将它们分配给真正的EditText

@Override
public void onCreate(Bundle savedInstanceState) {
       .
       .
       setContentView(...)
       myEditText = (EditText) findViewById (R.id.myedittextid);
       .
}

现在在您的工作线程中，您可以使用 myEditText.getText().toString() 来获取 EditText 中的值。

你为什么不直接使用runOnUiThread(). 您将在提供的链接中找到说明。

此方法将帮助您从工作线程运行和操作，并将其应用于 UI 线程

愚蠢的错误，更改
request.addProperty("Celsius",text_c.getText().toString() );
为request.addProperty("Fahrenheit",text_c.getText().toString() );

我的代码

public class Sample extends Activity {
/** Called when the activity is first created. */
private static String SOAP_ACTION1 = "http://tempuri.org/FahrenheitToCelsius";
private static String NAMESPACE = "http://tempuri.org/";
private static String METHOD_NAME1 = "FahrenheitToCelsius";
private static String URL = "http://www.w3schools.com/webservices/tempconvert.asmx";
EditText text_c, text_f;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    text_c = new EditText(this);
    text_f = new EditText(this);
    text_c.setText("76");
    new CelsiumToFahrenheit().execute();
}

private class CelsiumToFahrenheit extends AsyncTask<String, Void, String> {
    @Override
    protected String doInBackground(String... params) {

        SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME1);
        request.addProperty("Fahrenheit", "78");
        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER12);
        envelope.dotNet = true;
        envelope.setOutputSoapObject(request);
        HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
        System.setProperty("http.keepAlive", "true");
        try {
            androidHttpTransport.call(SOAP_ACTION1, envelope);
            androidHttpTransport.debug = true;
            Object result = envelope.getResponse();
            System.out.println("GetDataFromNetwork.doInBackground()" + result);
        } catch (IOException e) {
            // e.printStackTrace();
        } catch (XmlPullParserException e) {
            // e.printStackTrace();
        }
        return null;

    }

    @Override
    protected void onPostExecute(String result) {
        text_f.setText(result); // txt.setText(result);
    }
}

}
