我的RSS新闻出了问题，我得到了所有新闻，但我想用我的语言（法语）设置日期，那么怎么做呢？

NewsAdapter.java：

public class NewsAdapter extends BaseAdapter {
    List<News> news;
    Context context;

    public NewsAdapter(Context context, List<News> news) {
        this.news = news;
        this.context = context;
    }

    public void update(List<News> news) {
        this.news = news;
        notifyDataSetChanged();
    }

    @Override
    public int getCount() {
        return news.size();
    }

    @Override
    public Object getItem(int arg0) {
        return news.get(arg0);
    }

    @Override
    public long getItemId(int arg0) {
        return arg0;
    }

    @Override
    public View getView(int arg0, View arg1, ViewGroup arg2) {
        int screenSize = context.getResources().getConfiguration().screenLayout &
                Configuration.SCREENLAYOUT_SIZE_MASK;

        int titleSize;
        switch(screenSize) {
            case Configuration.SCREENLAYOUT_SIZE_XLARGE:
                titleSize = 26;
                break;
            case Configuration.SCREENLAYOUT_SIZE_LARGE:
                titleSize = 24;
                break;
            case Configuration.SCREENLAYOUT_SIZE_NORMAL:
                titleSize = 15;
                break;

                titleSize = 13;
                break;
            default:
                titleSize = 13;
        }
        int textSize;
        switch(screenSize) {
            case Configuration.SCREENLAYOUT_SIZE_XLARGE:

                break;

                break;

                textSize = 12;
                break;
            default:

        News n = (News)getItem(arg0);

        return v;
    }

Actualités.java（新闻）：

public class Actualites extends android.support.v4.app.Fragment{
    AsyncTask<Void, Void, List> a = null;
    NewsAdapter adapter = null;
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        View view = inflater.inflate(R.layout.activity_actualites, container, false);

        adapter = new NewsAdapter(getActivity(), new ArrayList<News>());
        list.setAdapter(adapter);
        list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {

                    HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
                    RssParser parser = new RssParser();
                    try {
                        return parser.parse(urlConnection.getInputStream());
                    } catch (XmlPullParserException e) {
                        e.printStackTrace();
                    }
                } catch (IOException e) {
                    e.printStackTrace();
                }
                return res;
            }

            @Override
            protected void onPostExecute(List result) {
                adapter.update(result);
            }
        };
        a.execute();
        TextView textView =(TextView)getActivity().findViewById(R.id.main_toolbar_title);
        textView.setText(getString(R.string.title_actu));
        textView.setTypeface(Typeface.createFromAsset(getActivity().getAssets(), "fonts/GothamBook.ttf"));
        return view;
    }
}

我在xml rss中的日期是英文：星期四，2015年4月9日15:21:51 +0000

那么如何用法语“解析”呢？

编辑----------------------

    String pubDate = Html.fromHtml(n.getPubDate()).toString().replace((char) 65532, (char) 32).trim();
    convertDateTimeZoneStr(pubDate);
    tv3.setText(pubDate);
    String content = Html.fromHtml(n.getContent()).toString().replace((char) 65532, (char) 32).trim();
    tv2.setText(content);
    return v;
}

public static String convertDateTimeZoneStr(String ddMMyyyy) throws ParseException {
    try{
        Date _date = new SimpleDateFormat("dd/MM/yyyy").parse(ddMMyyyy);
        SimpleDateFormat _simpleDateFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'");
        _simpleDateFormat.setTimeZone(TimeZone.getTimeZone("Europe/Paris"));
        return _simpleDateFormat.format(_date);
    }
    catch (ParseException e){
        e.printStackTrace();
    }
}

Answer 1

这里示例如何解析.U可以使用SimpleDateFormat

String dtStart = "yourdate";
SimpleDateFormat format = new SimpleDateFormat("MM/dd/yyyy HH:mm:ss");

date = format.parse(dtStart);
System.out.println("Date ->" + date);

Answer 2

以下代码是我一直在使用的示例：

public static String convertDateTimeZoneStr (String ddMMyyyy) throws ParseException {

    Date _date = new SimpleDateFormat("dd/MM/yyyy").parse(ddMMyyyy);

    SimpleDateFormat _simpleDateFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'");

    _simpleDateFormat.setTimeZone(TimeZone.getTimeZone("GMT"));

    return _simpleDateFormat.format(_date);

}

您可以将TimeZone.getTimeZone("GMT")更改为您想要的任何内容。请参阅TimeZone Ids https://gist.github.com/arpit/1035596的此列表。

编辑：

String pubDate = Html.fromHtml(n.getPubDate()).toString().replace((char) 65532, (char) 32).trim();

try{
    tv3.setText(convertDateTimeZoneStr(pubDate));
}
catch(ParseException e){
    // do whatever
}

String content = Html.fromHtml(n.getContent()).toString().replace((char) 65532, (char) 32).trim();
tv2.setText(content);

使用其他语言设置日期
