Android : How to make textview that it should not write new characters once its filled up

I have a textview that recieves user input. I would like that once the textview fills up with letters, that it should not place any more inside. What i have in my program now, is that although i cannot see the characters after the space is used up, the new letters are still being placed after the "...". It makes a big difference in my program and would like if someone can help me out thanks.
