问题描述

我在开发Android的一个简单的应用程序，但我坚持。我需要帮助检索本网站和在一个TextView显示。下面是code我一直在尝试使用。

 公共类MainActivity延伸活动{
    TextView的电视;
    最终字符串URL =htt​​p://mtn.co.ug/MTN-Internet/MTN-Mobile-Internet.aspx;    在此输入code @覆盖
    公共无效的onCreate（捆绑savedInstanceState）{
            super.onCreate（savedInstanceState）;
            的setContentView（R.layout.main）;
            电视=（的TextView）findViewById（R.id.textView）;
            新MyTask（）执行（）;
    }    私有类MyTask扩展的AsyncTask＆LT;太虚，太虚，太虚＆GT; {
            ProgressDialog PROG;
            //字符串title =;
            @覆盖
            在preExecute保护无效（）{
                PROG =新ProgressDialog（MainActivity.this）;
                prog.setMessage（加载......）;
                prog.show（）;
            }
            @覆盖
            保护无效doInBackground（虚空...... PARAMS）{
                尝试{
                    文档文件= Jsoup.connect(\"http://mtn.co.ug/MTN-Internet/MTN-Mobile-Internet.aspx\").timeout(90000).ignoreHttpErrors(true).get();                    / *为（元素表：Doc.select（tabscontent））{
                    对（件行：表格。选取（TR））{
                        元素TDS = row.select（TD）;
                        如果（tds.size（）→6）{
                            的System.out.println（tds.get（0）的.text（）+：+ tds.get（1）的.text（））;
                        }
                    }
                }                * /                //标题= Doc.title（）;
                对于（元黄釉：Doc.select（分区TBODY：包含（捆绑）：EQ（6）TR TD））{
                    的System.out.println（Yello.text（））;
                    tv.setText（Yello.text（））;                    //标题= Yello.toString（）;
                }
            }赶上（IOException异常五）{
                e.printStackTrace（）;

        对于（元黄釉：doc.select（分区：包含（包）TR））{            。字符串结果= Yello.select（TD）的文本（）修剪（）;

I am developing a simple app in android but am stuck. I need help to retrieve data from a table on this website and display it in a TextView. Below is the code I've been trying to use.

 public class MainActivity extends Activity {
    TextView tv;
    final String URL = "http://mtn.co.ug/MTN-Internet/MTN-Mobile-Internet.aspx";

    enter code here @Override
    public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.main);
            tv = (TextView) findViewById(R.id.textView);
            new MyTask().execute();
    }

    private class MyTask extends AsyncTask<Void, Void, Void> {
            ProgressDialog prog;
            //String title = "";
            @Override
            protected void onPreExecute() {
                prog = new ProgressDialog(MainActivity.this);
                prog.setMessage("Loading....");
                prog.show();
            }
            @Override   
            protected Void doInBackground(Void... params) {
                try {
                    Document Doc= Jsoup.connect("http://mtn.co.ug/MTN-Internet/MTN-Mobile-Internet.aspx").timeout(90000).ignoreHttpErrors(true).get();

                    /*for (Element table : Doc.select("tabscontent")) {
                    for (Element row : table.select("tr")) {
                        Elements tds = row.select("td");
                        if (tds.size() > 6) {
                            System.out.println(tds.get(0).text() + ":" + tds.get(1).text());
                        }
                    }
                }

                */          

                //title = Doc.title();
                for (Element Yello: Doc.select("div tbody:contains(Bundle):eq(6) tr td") ) {
                    System.out.println(Yello.text());
                    tv.setText(Yello.text());

                    //title = Yello.toString();
                } 
            } catch (IOException e) {
                e.printStackTrace();
            }
            //return null;
            return null;
        }

        @Override
        protected void onPostExecute(Void result) {
            super.onPostExecute(result);
            if (this.prog.isShowing()) { 
                this.prog.dismiss(); 
            }
            //tv.setText(title);

        }
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }
}

解决方案

Try This

Document doc = Jsoup.connect("http://www.mtn.co.ug/Mobile-Plans/PayAsYouGo/MTN-PerMinute.aspx").userAgent("Mozilla/5.0 (Windows NT 6.1; WOW64; rv:27.0) Gecko/20100101 Firefox/27.0")
                    .timeout(9999999).followRedirects(true).header("Accept", "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8").get();;


        for (Element Yello: doc.select("div:contains(bundle) tr") ) {

            String results = Yello.select("td").text().trim();
           tv.setTxt(results)


                                }

    }
