Android textview displays HTML Information

Recently, textview is used to display HTML information on the server. Android provides the HTML. fromhtml () method, which is easy to use.

1. Get the information returned by the server.

2. For example, the server returns

<HTML> 
Note that the  label must be added with a complete IP address. Otherwise, he cannot read the resource. He has been here for a while, shit.
3. Powerful html. fromhtml ()
Fromhtml (string source, imagegetter,

Taghandler) returns displayable styled text from the provided HTML string. any  tags in the HTML will use the specified imagegetter to request a representation of the image (use null if you don't

Want this) and the specified taghandler to handle unknown tags (specify NULL if you don't want this ). the comments are clear. Download images in imagegetter's getdrawable (asynchronous task download is recommended, but not in demo. If you need it, please leave a message. Welcome to my blog tracyzhang)
