TextView1 = (TextView) This.findviewbyid (r.id.textview1); textView2 = (TextView) This.findviewbyid (r.id.textview2 ); String html = "<font color= ' red ' >i love android</font><br>";//Set the font to red, then wrap html + = "<font color= ' # 0000FF ' ><big><i>i love java</i></big></font><p> ';//Set Font blue, large, italic, set to a section of HTML + = "<big><a href= ' http://www.baidu.com ' > Baidu </a></big>";//Add hyperlinks to Baidu text charsequence Charsequence = html.fromhtml (Html); Textview1.settext (charsequence); Textview1.setmovementmethod ( Linkmovementmethod                              . getinstance ());//Set the information in the text click to produce a hyperlink string text = "My url:http://www.sina.com\n"; text + = " My Email:[email protected]\n "; text + =" My Phone: + 010-87439874 "; textview2.settext (text); Textview2.setmovementmethod ( Linkmovementmethod                              . getinstance ());

3. Description

Common tags that can be set in TextView are:

• <font>: Sets the color and font.
• <big>: Set Font size
• <small>: Setting the Font s
• <i><b>: Italic Bold
• <a>: Connection URL
• : Pictures

Using these tags, you can use the Html.fromhtml method to convert the string of these tags into an charsequence interface, and then set it in Textview.settext (). If you need to respond to an HTML tag that responds to your settings, you need to set Textview.setmovementmethod (Linkmovementmethod.getinstance ()).

Android:autolink property to set, the following is an introduction to the Android:autolink property:

• None: Default, does not match any connections.
• Web: URL.
• Email: email.
• Phone: Telephone number.
• Map: Match map URLs.
• All: matches all connections.
