感谢

这里的code我使用的部分内容：

here's a portion of the code i am using:

@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);
    }

}

感谢再次任何帮助将是非常美联社preciated！

Thank again any help would be really appreciated!!

推荐答案

当您设置文本，将其设置为从HTML文本：

When you set the text, set it as text from html:

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

如果你想显示从HTML的图像，您需要使用与网页视图沿着这些路线的东西的：

If you want to show images from the html you'll need to use a WebView with something along these lines:

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