Android "scroll" Text in TextView

Question

I got the following situation: I have a String with about 40 - 50 Words and a TextView with max. 3 Lines. Is it possible to get the TextView to Display the a text snippet starting from a specific Word (not the first one) or Regex from the String? Example:

String: Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore magna

Shown in TextView: ...consetetur sadipscing elitr, sed diam nonumy...

you can use TextView method: `setMaxLines` to make the last has `...`, if the line is bigger than max lines, but you want the first, may be need your custom implements. — idiottiger, Jan 09 '12 at 08:53
Why not manipulate the string before setting it into the textview? — reTs, Jun 26 '12 at 09:31

You don't need to use a ScrollView actually. Just set the android:maxLines and android:scrollbars = "vertical" properties of textview in layout xml file. Then use the TexView.setMovementMethod(new ScrollingMovementMethod()) in the Code. Bingo!!!! It scrolls. Taken from this Answer.

you can implement the following change to your code:

urBtn.setEllipsize(TruncateAt.MARQUEE);
urBtn.setMarqueeRepeatLimit(-1);

This will set the text in the button to scroll always when focussed

Sorry that is not what I want. I don't want the text to be scrollable, i just want it to scroll at a specific position and then stay there. – Thommy Jan 09 '12 at 08:55
