Android builds basic XML animations

Create a new folder under res named Anim, creating an XML file, such as creating a a1.xml

<?xml version= "1.0" encoding= "Utf-8"?>
<set xmlns:android= "Http://schemas.android.com/apk/res/android" >
Write an animation here
</set>

Alpha: Gradient Transparency effect

Rotate: Rotate animation effect

Scale: Stretch animation effect

Translate: Panning animation effect

Use the following XML to create animation-part of the animation, details see source code:

Alpha: Gradient Transparency effect- from there to none

A1.xml

<set xmlns:android= "Http://schemas.android.com/apk/res/android" >    <alpha        android:duration= "3000 "        android:fromalpha=" 1.0 "        android:toalpha=" 0.0 "/></set>

rotate: Rotate animation effect-Clockwise

Rotate.xml

<rotate        android:duration= "android:fromdegrees="        0 "        android:interpolator=" @android: anim/ Accelerate_decelerate_interpolator "        android:pivotx=" 50% "        android:pivoty=" 50% "        android:todegrees = "+350"/>

scale: Stretch animation effect-zoom to the lower-right corner

Scale.xml

<scale        android:duration= "" "        android:fillafter=" false "        android:fromxscale=" 1.0 "        android: Fromyscale= "1.0"        android:interpolator= "@android: Anim/accelerate_decelerate_interpolator"        android: pivotx= "100%"        android:pivoty= "100%"        android:toxscale= "0"        android:toyscale= "0"/>

Translate: Panning animation effect-top to bottom

Translate.xml

<translate        android:duration= "android:fromxdelta="        0 "        android:fromydelta=" 0 "        android: Toxdelta= "0"        android:toydelta= "/>"

If it is a collection of animations, it is loaded in order under the set node. The following rotation and movement of the set

<set xmlns:android= "Http://schemas.android.com/apk/res/android" >    <rotate        android:duration= " "        android:fromdegrees=" 0 "        android:interpolator=" @android: Anim/accelerate_decelerate_interpolator "        android:pivotx= "50%"        android:pivoty= "50%"        android:todegrees= "+350"/>    <translate        android:duration= "Android:fromxdelta="        0 "        android:fromydelta=" 0 "        android:toxdelta=" 0 "        android:toydelta="/></set>

Write a tool class to load this animation

Animaxmlutils.java

/** * Animation using XML design * */public class Animaxmlutils {private static Animation anim;/** * Gradient transparent animation, transparency: 1.0~0.0 * * @return */pu Blic static Animation Alphafrom1to0 (context context) {Anim = animationutils.loadanimation (context, r.anim.a1); return Anim;} /** * Gradient Transparent animation, transparency: 1.0~0.0 * * @return */public static Animation alphafrom0to1 (context context) {Anim = Animationutils.load Animation (context, R.ANIM.A2); return anim;} /** * Rotate animation, clockwise * * @return */public static Animation rotateticlockwise (context context) {Anim = Animationutils.loadani Mation (context, r.anim.rotate); return anim;} /** * Rotate animation, counter-clockwise * * @return */public static Animation rotateanticlockwise (context context) {Anim = Animationutils.loada Nimation (context, r.anim.rotate1); return anim;} /** * Telescopic animation, from have to no * * @return */public static Animation scalefrom1to0 (context context) {Anim = Animationutils.loadanimation (context, R.anim.scale); return anim;} /** * Telescopic animation, from have to no * * @return */public static Animation scalefrom0to1 (context context) {Anim = anImationutils.loadanimation (context, r.anim.scale1); return anim;} /** * Pan animation, from top to bottom * * @return */public static Animation Translatetoptobottom (context context) {Anim = Animationutils.loadan Imation (context, r.anim.translate); return anim;} /** * Pan animation, from bottom to top * * @return */public static Animation translatebottomtotop (context context) {Anim = Animationutils.loadan Imation (context, r.anim.translate1); return anim;} /** * Four Animation sets * * @return */public static Animation Animationroaandtranset (context context) {Anim = Animationutils.loadani Mation (context, r.anim.aniset); return anim;}}
