Animate MaxLines and Ellipsize

Question

I have textview which contains a part of a text. When the user clicks the arrow, the textview resizes so the full text is shown. See the images below for an example:

Answer 1

While animating maxLines works, the result is a bit choppy since your view height jumps a lot.

int startHeight = content.getMeasuredHeight();
content.setMaxLines(Integer.MAX_VALUE);
content.measure(
            View.MeasureSpec.makeMeasureSpec(parent.getWidth(), View.MeasureSpec.AT_MOST),
            View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED));
int endHeight = content.getMeasuredHeight();

content is a TextView with maxLines set to 2. Now you can animate the TextView height instead. Edit: TextView scrolls when it can't fit it's content vertically, you'll need workarounds. setMovementMethod(null) disables scrolling, but it also disables link clicking. Because Android.
