Hi, Johan.

I think this library needs some change.

a) it crashes if you set a text longer than 11 characters (RevealText)
b) the animation starts anyway, even if you don't start it explicitly (RUN)
c) there is a default text to delete (Hello World)
d) setting the view top position using VerticalCenter the position will be wrong
e) a "RevealTextAnimationEnd" event would be helpful


Thank you for your great work on this site!

Hi, Johan.

I think this library needs some change.

a) it crashes if you set a text longer than 11 characters (RevealText) - Sorted - make the text as long as you like
b) the animation starts anyway, even if you don't start it explicitly (RUN) - It only starts with the call to RUN. If you want the animation to stop then stop the timer
c) there is a default text to delete (Hello World) - Sorted
d) setting the view top position using VerticalCenter the position will be wrong - Use B4A code or Designer code as in the attached project to position the customview
e) a "RevealTextAnimationEnd" event would be helpful - The original Github code does not provide for this. Attached is the Java code (original + wrapper). Change it to whatever will suite you.


Thank you for your great work on this site!
New lib files attached - make the string as long as you like. Note that the call to RUN has changed to startAnimation.
