In
Android
Medium,
Animation
Animation effects can be implemented in two ways, one is
Tweened
Animation
Gradient animation, the other is
Frame
By Frame Animation
Screen conversion animation.

Tweened Animation
There are two types of gradient Animation:

1. Alpha


Gradient transparency animation effect

2. Scale


Gradient scaling animation effect

Frame by frame animation
There are two types of screen conversion Animation:

1. Translate


Animation Effect

2. Rotate


Animation effects of screen transfer and Rotation

In
Res
Create a folder
Anim
And create
Animation. xml
File:

<? XML version = "1.0"
Encoding = "UTF-8"?>

<Set

Xmlns: Android = "http://schemas.android.com/apk/res/android">

Android: fromxdelta = "0"
//
When the animation is set to start
X
Coordinates

Android: toxdelta = "-100% P"
//
Set the animation End Time

Android: duration= "300"
//
Set the animation duration

</Translate>

<Alpha

Android: fromalphi = "1.0"
//
Sets the transparency at the beginning of the animation.

1.0
Indicates opacity

Android: toalpha = "0.0"
//
Sets the transparency at the beginning of the animation.

0.0
Completely transparent

Android: duration= "300"
//
Set the animation duration
300
Millisecond

/>

<Scale

Android: interpolator ="
//
Set the animation Reader

Android: fromxscale = "0.0"
//
When the animation is set to start
X
Scaling length on coordinates

Android: toxscale = "1.4"
//
Set the animation End Time

Scaling length on coordinates

Android: fromyscale = "0.0"
//
When the animation is set to start
Y
Scaling length on coordinates

Android: toyscale = "1.4"
//
When the animation is set to start
Y
Scaling length on coordinates

Android: Required Tx = "50%"
//
Set the animation to
X
Coordinates

Android: Ty = "50%"
//
Set the animation to
Y
Coordinates

Android: fillafter = "false"
//
This animation is used before the animation ends.

Android: Duration = "700 "//
Set the animation duration

/>

 
<Rotate

Android: interpolator =
//
Set the animation Reader

"@ Android: anim/accelerate_decelerate_interpolator"

Android: fromdegrees = "0"
//
Set the animation start angle

Android: todegrees = "+ 350"
//
Sets the rotation angle at the animation end.

Android: Required Tx = "50%"
//
Set the animation to
X
Coordinates

Android: Ty = "50%"
//
Set the animation to
Y
Coordinates

Android: duration= "3000"
//
Set the animation duration

/>

</Set>

Exploitation
Animationutils. loadanimation
Load an animation

Animation animation;

Animation = animationutils. loadanimation (this,
R. anim. animation );

Then, you can use
Startanimation ()
Method.

//
Compile an animation object and obtain the Custom Animation style.

Animation = animationutils. loadanimation (this,
R. anim. animation );

Spinner. setontouchlistener (new Spinner. ontouchlistener (){

@ Override

Public
Boolean ontouch (view V, motionevent event ){

//
Todo auto-generated method stub

//
Run the animation
Animation

V. startanimation (animation );

//
Set
Spinner
Sets the visibility to invisible.

V. setvisibility (view. Invisible );

Return
False;

}

});
