Android Animation

by

With parameters like start value, end value, size, time duration, rotation angle, etc., Tween Animation performs the desired animation on an object. Tween Animation in Android is provided by a class called Animation, to be applied to any type of object. In Android, various classes and interfaces are present in the android. animation package, for animation development. Animation in Android can be simply understood as the phenomenon of changing the object property and behavior at run time. To do animation in android, we can use various ways. To start and end the animation, the methods of the AnimationDrawable class are used. The time-based animation can also be used for animation in Android.

Example:

In the below example, we are demonstrating the usage of android animation.

activity_main.xml:

In the activity_main.xml file, we will add some TextView, ImageView, and Buttons from the palette.
