How to show html text in BlackBerry?

Question

Hi, all.

Is there any way to show LOCAL html string in my BB application?

For example: I have a string

"<b>text-text-text</b> <A href="http://stackoverflow.com"&gt;link&lt;/A&gt;"

How can I parse and show it as

text-text-text link?

Thanks.

You can use a BrowserField to render content in your application as a Field. In order to render HTML provided as a String rather than a URL, see this answer which involves mocking an HttpConnection.
