I have a `TextView` which firstly shows a small portion of a long text.

The user can press a "see more" button to expand the `TextView` and see the rest of that text.

Making tests, I can reach that by simply interchange the value of `TextView.setMaxLines` between 4 for collapsing and Integer.MAX\_VALUE for expanding.

Now, I would like that this behavior would be accompanied by an animation. I know that in [this question](https://stackoverflow.com/questions/5927977/textview-expand-animation-like-in-android-market) one solution is almost done, but I tried to implement it and I have no success.

Can someone help me with this?
