Android RSS阅读器描述数据获取错误

Question

我正在开发一个 android rss 阅读器，但我面临的问题是在尝试从 rss 提要中获取数据时，其中描述包含如下 html 内容:

<item>
    <title>Katima&#45;Comic</title>
    <link>http://thelinknewspaper.ca/article/3063</link>

    <guid isPermaLink="false">thelink_entry_3063</guid>
    <description><![CDATA[

    </p>


    <p>This is the story of Andrew Murchison, a Katimavik volunteer whose life was changed by the federal youth program.</p>

我在 textview 中显示内容，它显示内容与 html 标签一样!

如何在特定区域内使用滚动条以易于阅读的方式显示它

谢谢

这是我使用的部分代码:

@Override
    public View getView(final int position, View convertView, ViewGroup parent) {
        View view = convertView;
        ViewHolder holder;
        if (view == null) {
            LayoutInflater inflater = (LayoutInflater) activity
                    .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            view = inflater.inflate(R.layout.row, null);

            holder = new ViewHolder();
            view.setTag(holder);
        } else {
            holder = (ViewHolder) view.getTag();
        }

        if ((items == null) || ((position + 1) > items.size()))
            return view;

        objBean = items.get(position);


        holder.title = (TextView) view.findViewById(R.id.txttitle);
        holder.description = (TextView) view.findViewById(R.id.txtdesc);



        if (holder.title != null && null != objBean.getTitle()
                && objBean.getTitle().trim().length() > 0) {
            holder.title.setText(Html.fromHtml(objBean.getTitle()));
        }
        if (holder.description != null && null != objBean.getDescription()
                && objBean.getDescription().trim().length() > 0) {
            holder.description.setText(Html.fromHtml(objBean.getDescription()));
        }


        // Even and odd Row...
        if ((position % 2) == 0) {
            view.setBackgroundResource(R.drawable.bg_list_even);
        } else {
            view.setBackgroundResource(R.drawable.bg_list_odd);
        }

        return view;
    }

和

public class NewsDetail extends Activity {
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.detail);

        Bundle b = this.getIntent().getExtras();

        String title = b.getString("title");
        String desc = b.getString("description");

        final String link = b.getString("link");


        TextView tvtitle = (TextView) findViewById(R.id.tvtitle);
        TextView tvdesc = (TextView) findViewById(R.id.tvdesc);


        Button btnWeb = (Button) findViewById(R.id.btngotolink);
        btnWeb.setOnClickListener(new OnClickListener() {
            public void onClick(View v) {
                startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(link)));
            }
        });

        tvtitle.setText(title);
        tvdesc.setText(desc);


        setTitle(title);
    }

}

再次感谢任何帮助将不胜感激!!

Answer 1

设置文本时，将其设置为html中的文本:

tvdesc.setText(Html.fromHtml(desc));

如果你想显示来自 html 的图像，你需要使用 WebView沿着这些方向:

myWebview.loadData(myHtmlString, "text/html; charset=UTF-8", null);
