textview setText Html fromHtml   lt font color  rgb  gt   text contain   lt  font gt        It will give the color exactly what you have made in html editor   just set the textview and concat it with the textview value  Android does not support span color  change it to font color in editor and you are all set to go

This can be achieved using a Spannable String  You will need to import the following  import android text SpannableString   import android text style BackgroundColorSpan   import android text style StyleSpan    And then you can change the background of the text using something like the following   TextView text    TextView  findViewById R id text login   text setText      text append  Add all your funky text in here    Spannable sText    Spannable  text getText    sText setSpan new BackgroundColorSpan Color RED   1  4  0     Where this will highlight the charecters at pos 1 - 4 with a red color  Hope this helps
