具有utf-8和特殊字符的TextView

Question

StackOverflowers!

I load some text from a webpage. Everything works fine, and shows up in the TextViews. But, when the blogs on the webpage have some words with special characters like an: é or something. My Textview show characters like these: Á©..

Can anybody tell what I need to import, call or something like that to show everything tidy?

Thanks,

UPDATE 1 + 2:

TextView intro_text = (TextView) item_view.findViewById(R.id.item_intro);
intro_text.setText(Html.fromHtml(current_post.get_intro()));    

current_post.get_intro() is the adres where the loaded text is. :-) Because I use a listview with many rows..

EDIT:

public class connectTask extends AsyncTask<String, String, String> {
    @SuppressWarnings({ "deprecation" })
    @Override
    protected String doInBackground(String... message) {

        Log.v("Correct Load", "Starting ");
        URL u;
        InputStream is = null;
        DataInputStream dis;
        String s;

        try {
            Log.v("Connecting...");
            u = new URL("http://.......");
            is = u.openStream();
            dis = new DataInputStream(new BufferedInputStream(is));
            Log.v("Connected");

            try {
                while ((s = dis.readLine()) != null) {
                    if (s.contains("post_wrapper")) {
                        for (int i = 0; i < j; i++) {
                            while ((s = dis.readLine()) != null) {
                                if (s.contains("post_intro")) {
                                    break;
                                }
                            }

                            if (s != null) {
                                s = dis.readLine();
                                Log.v("Intro", s); intro[i] = s.substring(s.indexOf("<p>") + 3, s.indexOf("</p>"));
                                Log.e("Intro", "Found intro:" + intro[i]);
                            }   
                        }
                    }
                }
            } catch (Exception e) {
                e.printStackTrace();
            }
        } catch (MalformedURLException mue) {
            System.out.println("Ouch - a MalformedURLException happened.");
            mue.printStackTrace();
            System.exit(1);

        } catch (IOException ioe) {
            System.out.println("Oops- an IOException happened.");
            ioe.printStackTrace();
            System.exit(1);

        } finally {
            try {
                if (is != null)
                    is.close();
            } catch (IOException {
            }
        }
        return null;
    }

This is the read/received part.

Answer 1

tricky but worked for me: use Html.fromHtml() twice , I mean:

text.setText(Html.fromHtml(Html.fromHtml(your_html_text).toString()));

EDIT .

Your problem is not in this TextView because you are getting broken encoding even in your logcat, so you should know when exactly , the encoding is broken ; this get_intro() is returning a bad string, so you should show us , what is this get_intro() doing ? how is it taking the string ? from what ? you should share the code of this get_intro() else nobody can help you...

Answer 2

Replace

DataInputStream dis = new DataInputStream(new BufferedInputStream(is));

With

BufferedReader dis = new BufferedReader(new InputStreamReader(is, "UTF-8"));

Because DataInputStream.readLine() is deprecated and is discouraged for the following reason:

This method cannot be trusted to convert bytes to characters correctly.

BufferedReader also has a readLine method, so the rest of your code should be pretty much unchanged.

Also, whenever you use @SuppressWarnings({ "deprecation" }) I strongly suggest that you be extra careful and make sure you can use the deprecated method despite the warning.
