Summary

Now we have another app-enhancing trick up our sleeves. In this chapter, we saw that animations in Android are quite straightforward. We designed an animation in XML and added the file to the anim folder. Next, we got a reference to the animation in XML with an Animation object in our Kotlin code.

We then used a reference to a widget in our UI, set an animation to it using setAnimation, and passed in the Animation object. We commenced the animation by calling startAnimation on the reference to the widget.

We also saw that we can control the timing of animations and listen for animation events.

In the next chapter, we will learn about drawing graphics in Android. This will be the start of several chapters on graphics, where we will build a kid's-style drawing app.
