Animation translate, scale, alpha, rotate animation effects

Type of animation

Android animation is made up of four different types

in XML

Alpha	Gradient Transparency Animation effect
Scale	Gradient Dimension Stretch animation effect
Translate	Move animation effect on picture transition position
Rotate	Picture Transfer rotation animation effect

In Javacode

Alphaanimation	Gradient Transparency Animation effect
Scaleanimation	Gradient Dimension Stretch animation effect
Translateanimation	Move animation effect on picture transition position
Rotateanimation	Picture Transfer rotation animation effect

Android Animation mode

Animation There are two main modes of animation: one is tweened animation (gradient animation )

in XML	Javacode
Alpha	Alphaanimation
Scale	Scaleanimation

One is frame by frame (picture conversion animation )

in XML	Javacode
Translate	Translateanimation
Rotate	Rotateanimation
