Animation In Android

• Android is a mobile operating system developed by
  Google, based on a modified version of the Linux
  kernel and other open source software and
  designed primarily for touchscreen mobile devices
  such as smartphones and tablets.
• Animation API was introduced by Google in Android
  3.0 which gives us the flexibility to change
  object properties over a certain time interval.
  The Animations Framework allows us to create
  visually attractive animations and transitions in
  our apps.

Types of Animation

• There are three types of animation.
• 1. View Animation

Animation Methods

• The Animation class has many methods given below
• 1.start() This method will start the animation.
• 2.setDuration(long duration) This method sets
  the duration of an animation.
• 3.getDuration() This method gets the duration.
• 4.end() This method ends the animation.
• 5.cancel() This method cancels the animation.

Interpolator

• It is used to insert or apply an additional
  animation effects between the start and the end
  value of the property of an object. It is also
  used to define the rate of change of an animation

Animation File In Android Studio 

• To apply Animations to our Application sometimes
  we need to make an anim folder in Android Studio
  to store animation file under the resource folder
  of our application. Basically there are two
  options for resource types. You can set any of
  these two given below
• animator/ XML files that define property
  animations.
• anim/ XML files that define tween animations

Animated properties

• Common properties commonly animated on views
  include

Property Description
alpha Fade in or out
rotation, rotationX, rotationY Spin or flip
scaleX ,scaleY Grow or shrink

Setting The Animation Listeners

• Animation listeners can be set by implementing
  Animation Listener in our Activity. If you will
  use Animation Listener, then you will have to
  override following methods.
• Scale Animation
• Rotate Animation
• Translate Animation
