从processFinish在AsyncTask的Andr​​oid的返回值 [英] Android return value from processFinish in AsyncTask

问题描述

在此跌破codeI想通过从 processFinish 的方法要使用的数据，在课外，但我无法修复的问题，我不能返回值 processFinish 在通话的功能。

in this below code i want to pass data from processFinish method to use that in outside class but i can not fix problem and i can not return value from processFinish in call function.

public class WSDLHelper  implements AsyncResponse{
    public SoapObject request;

    private String MainResult;

    public String call(SoapObject rq){

        new ProcessTask(rq, this).execute();
        return MainResult;
    }

    @Override
    public void processFinish(String output) {
        MainResult = output;
    }
}

class ProcessTask extends AsyncTask<Void, Void,  String> {
    public AsyncResponse delegate=null;

    SoapObject req1;

    public ProcessTask(SoapObject rq, AsyncResponse delegate) {
        req1 = rq;
        this.delegate = delegate;
    }

    @Override
    protected void onPreExecute() {
        super.onPreExecute();
    }

    @Override
    protected String doInBackground(Void... params) {

        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
        envelope.setOutputSoapObject(this.req1);

        AndroidHttpTransport transport = new AndroidHttpTransport(Strings.URL_TSMS);
        transport.debug = true;

        String result = null;
        try {
            transport.call(Strings.URL_TSMS + this.req1.getName(), envelope);
            result = envelope.getResponse().toString();
        } catch (IOException ex) {
            Log.e("" , ex.getMessage());
        } catch (XmlPullParserException ex) {
            Log.e("" , ex.getMessage());
        }

        if (result.equals(String.valueOf(Integers.CODE_USER_PASS_FALSE))) {
            try {
                throw new TException(PublicErrorList.USERNAME_PASSWORD_ERROR);
            } catch (TException e) {
                e.printStackTrace();
            }
        }

        return result;
    }

    protected void onPostExecute(String result) {
        delegate.processFinish(result);
    }
}

请帮我制定通话方法输出价值回归之外类。谢谢

please help me to develop call method to return output value to outside class. thanks

推荐答案

目前要实现AsyncResponce。 所以 替换

There you are implementing AsyncResponce. so Replace

new ProcessTask(rq, new AsyncResponse() {
            @Override
            public void processFinish(String output) {
                MainResult = output;
            }
        }).execute();

到

new ProcessTask(rq, this).execute();

然后你的类 overrided 方法，P rocessFinish（字符串输出）将调用。

Then your class overrided method processFinish(String output) will call.

和使用在processFinish（你的价值），而不是值由call（）方法retured。

And use your value at processFinish() rather than value retured by call( ) method.
