If you are reading that text from a file or from the network   You can achieve it by adding HTML tags to your text like mentioned  This text is  lt i gt italic lt  i gt  and  lt b gt bold lt  b gt  and  lt u gt underlined lt  u gt   lt b gt  lt i gt  lt u gt bolditalicunderlined lt  u gt  lt  b gt  lt  i gt    and then you can use the HTML class that processes HTML strings into displayable styled text      textString is the String after you retrieve it from the file textView setText Html fromHtml textString

For bold and italic whatever you are doing is correct for underscore use following code  HelloAndroid java     package com example helloandroid    import android app Activity   import android os Bundle   import android text SpannableString   import android text style UnderlineSpan  import android widget TextView   public class HelloAndroid extends Activity   TextView textview      Called when the activity is first created      Override public void onCreate Bundle savedInstanceState        super onCreate savedInstanceState       setContentView R layout main       textview    TextView findViewById R id textview       SpannableString content   new SpannableString getText R string hello        content setSpan new UnderlineSpan    0  content length    0       textview setText content         main xml   lt  xml version  1 0  encoding  utf-8   gt   lt TextView xmlns android  http   schemas android com apk res android  android id    id textview  android layout width  fill parent  android layout height  fill parent  android text   string hello  android textStyle  bold italic   gt    string xml   lt  xml version  1 0  encoding  utf-8   gt    lt resources gt     lt string name  hello  gt Hello World  HelloAndroid  lt  string gt     lt string name  app name  gt Hello  Android lt  string gt   lt  resources gt

This should make your TextView bold  underlined and italic at the same time   strings xml   lt resources gt       lt string name  register  gt  lt u gt  lt b gt  lt i gt Copyright lt  i gt  lt  b gt  lt  u gt  lt  string gt   lt  resources gt    To set this String to your TextView  do this in your main xml    lt  xml version  1 0  encoding  utf-8   gt   lt TextView xmlns android  http   schemas android com apk res android      android id    id textview      android layout width  fill parent      android layout height  fill parent      android text   string register    gt    or In JAVA    TextView textView   new TextView this   textView setText R string register     Sometimes the above approach will not be helpful when you might have to use Dynamic Text  So in that case SpannableString comes into action    String tempString  Copyright   TextView text  TextView findViewById R id text   SpannableString spanString   new SpannableString tempString   spanString setSpan new UnderlineSpan    0  spanString length    0   spanString setSpan new StyleSpan Typeface BOLD   0  spanString length    0   spanString setSpan new StyleSpan Typeface ITALIC   0  spanString length    0   text setText spanString     OUTPUT
