The rich text style of TextView and the specific use of spannablestring

There are several ways to make TextView have a style that is linked in a Web page:

1. Use the layout properties to apply the effect automatically, using the Android:autolink property

< Textview > ... android:autolink= "All" ..... </ Textview >

2. Use <a> tags in string literals

3, in the Java code directly settext

Textview.settext (    html.fromhtml (         "<b>text3:</b>  Text with a" +         "<a href =\ "http://www.google.com\" >link</a> "+         " created in the Java source code using HTML. " ) ); Textview.setmovementmethod (Linkmovementmethod.getinstance ()) ;

4. Achieve rich results by creating spanablestring strings and creating one or more spans above, for example:

New Spannablestring ("Click here to dial the phone.") );   Ss.setspan (new Stylespan (Typeface.bold), 0, 6, spanned.span_exclusive_exclusive);   Ss.setspan (new urlspan ("tel:4155551212"), andspanned.span_exclusive_exclusive);      = (TextView) Findviewbyid (R.ID.TEXT4);   

About the specific use of spannablestring:
