Question

我正在处理申请，我需要从网站上复制一份联系表格。 http://www.telekino.com.ar/info/contacto。我理解获取数据的jsoup原则，但我对发送数据的概念并不擅长。并且提交按钮没有网页或邮件地址，以便我在哪里发送数据。

这是我的代码

public class Contactenos extends Fragment {

public Contactenos(){}

private DrawerLayout mDrawerLayout;
public static String namet;
public static String localidadt;
public static String telefonot;
public static String emailt;
public static String consultat;
public static String maildestt;
ProgressDialog mProgressDialog;


String url = "http://www.telekino.com.ar/info/contacto/#contactenos";
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {

    View rootView = inflater.inflate(R.layout.contacto, container, false);

    EditText name=(EditText)rootView.findViewById(R.id.nombre);
    EditText localidad=(EditText)rootView.findViewById(R.id.localidad);
    EditText telefono=(EditText)rootView.findViewById(R.id.telefono);
    EditText email=(EditText)rootView.findViewById(R.id.email);
    EditText consulta=(EditText)rootView.findViewById(R.id.consulta);

    RadioGroup rg = (RadioGroup) rootView.findViewById(R.id.maildest);

    RadioButton rb = (RadioButton) rg.findViewById(rg.getCheckedRadioButtonId());
    maildestt= String.valueOf(rb);


    namet = name.getText().toString();
    localidadt = localidad.getText().toString();
    telefonot = telefono.getText().toString();
    emailt = email.getText().toString();
    consultat=consulta.getText().toString();


    Button sendbut= (Button)rootView.findViewById(R.id.sendbutton);
    sendbut.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            new Title().execute();

        }
    });




    return rootView;
}



// Title AsyncTask
private class Title extends AsyncTask<Void, Void, Void> {

    String sorteofech;


    @Override
    protected void onPreExecute() {
        super.onPreExecute();
        mProgressDialog = new ProgressDialog(getActivity());
        mProgressDialog.setTitle("TELEKINO");
        mProgressDialog.setMessage("enviando...");
        mProgressDialog.setIndeterminate(false);
        mProgressDialog.show();
    }


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

        return null;
    }

    @Override
    protected void onPostExecute(Void result) {
        super.onPostExecute(result);
        // Connect to the server and do a post
        try {
            // Connect to the web site
            Document doc = Jsoup.connect(url)
                    .data("nombre", namet)
                    .data("localidad", localidadt)
                    .data("telefono", telefonot)
                    .data("email", emailt)
                    .data("dpto", maildestt)
                    .data("consulta", consultat)
                    .post();





        } catch (IOException e) {
            e.printStackTrace();
        }
        mProgressDialog.dismiss();

    }


}

}

这种方式崩溃，我不确定是否能正常工作。

这个是Logcat

如何修复它或在android上回复此联系表单的最佳方法是什么？

Answer 1

在doInBackground中调用connect方法。然后它将在后台线程中运行网络请求。

OnPostExecute将在主线程上运行，而不是在后台运行。要执行后台任务，请使用doInBackGround。

如果要从http请求的结果更新UI，请使用doInBackGround。

如何使用jsoup提交包含值的表单？
