The normal way to create an animation in Android is through XML. We can write XML animations and then load and play them in Java on a specified UI widget. So, for example, we can write an animation that fades in and out five times over 3 seconds and then play that animation on ImageView or any other widget. We can think of these XML animations as a script as they define the type, order, and timing of the animation.
Let's explore some of the different properties that we can assign to our animations and how to use them in our Java code, and finally, we can make a neat animated mini app to try it all out.
We have learned that XML can also be used to describe animations as well as UI layouts, but let's find out exactly how. We can state properties of an animation that describe the starting and ending appearance of a widget. The XML can then be loaded by our Java code by referencing the name of the XML file that contains it and turning it into...
