Answer 1

Use Html.fromHtml(str):

String str="<font size =\"20\"><B>Bold</B> <br/> Then Normal Text<br/>
                         <i>Then Italic</i> </font>" +
                       "<br/> <font color=\"green\" >this is simple sentence </font>" +
                       "<br/> <font face=\"verdana\" >this is simple sentence </font>"+
                       "<br/><br/><br/><br/><a>this is simple sentence</a>";
Spanned strHtml= Html.fromHtml(str);

TextView tv = (TextView)findViewById(R.id.textView);
tv.setText(strHtml);

Or you can use SpannableString.
