Undersanding Animation Function In Android

I want to use the following code snippet, please help me in understanding the given functions or suggest me online documentation that can I use. view.animate().setDuration(2000).a

Solution 1:

• alpha(0) the view's alpha property will be animated to this value
• withEndAction() means at the end of the animation the following action will take place
