Which HTML tags are supported by Android TextView?

Question

Android's TextView class can display formatted text via HTML.fromHtml() as explained for example here: HTML tags in string for TextView

The TextView class can only deal with a small subset of HTML, but I do not know which tags and attributes are supported and which are not. The summary given here: http://commonsware.com/blog/Android/2010/05/26/html-tags-supported-by-textview.html does not seem to be correct. E.g. <div align="..."> does NOT work for me using Android 2.2

Answer 2

I noticed that this article:

https://web.archive.org/web/20171118200650/http://daniel-codes.blogspot.com/2011/04/html-in-textviews.html

lists <div> as being supported by Html.fromHtml(), but it doesn't show support for the "align" attribute.

(Other supported attributes are shown for tags on that page.)

The author says he constructed the reference by looking at code in the git repositories for Android.

Edit: Over time, it appears the list of supported tags has changed. See this later post for example: http://www.grokkingandroid.com/android-quick-tip-formatting-text-with-html-fromhtml/ .

Based on both those articles, I'd suggest that examining the source code seems to be the most reliable way to get the recent information.
