Android animation effects translate, scale, alpha, rotate

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

alphaanimati On	gradient transparency animation effect
scaleanimation
translateanimation
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

Alpha XML fade Out effect

Alpha XML fade-in effect

Rotate.xml Rotation Effect:

<?xmlversion="1.0"encoding="Utf-8"?> <setxmlns:android="http://schemas.android.com/apk/res/android"> <Rotate Android:interpolator="@android: Anim/accelerate_decelerate_interpolator"android:fromdegrees=" -"android:todegrees="-360"Android:pivotx="10%"Android:pivoty="100%"android:duration="10000"/> </Set> <!--Fromdegrees the angle at which the animation starts todegrees the rotation angle of the object at the end of the animation, which means that the clockwise Pivotx property is the start position of the animation relative to the object's x-coordinate Pivoty property is the start position of the animation relative to the object's y-coordinate -

Restart for re-execution, direction unchanged-
