Android动画开发——Animation动画效果

动画类型

Android的animation由四种类型组成

XML中

alpha	渐变透明度动画效果
scale	渐变尺寸伸缩动画效果
translate	画面转换位置移动动画效果
rotate	画面转移旋转动画效果

JavaCode中

AlphaAnimation	渐变透明度动画效果
ScaleAnimation	渐变尺寸伸缩动画效果
TranslateAnimation	画面转换位置移动动画效果
RotateAnimation	画面转移旋转动画效果

Android动画模式

Animation主要有两种动画模式：
一种是tweened animation(渐变动画)

XML中	JavaCode
alpha	AlphaAnimation
scale	ScaleAnimation

一种是frame by frame(画面转换动画)

XML中	JavaCode
translate	TranslateAnimation
rotate	RotateAnimation

如何在XML文件中定义动画

①　打开Eclipse，新建Android工程
②　在res目录中新建anim文件夹
③　在anim目录中新建一个myanim.xml(注意文件名小写)
④　加入XML的动画代码

<?xml version="1.0" encoding="utf-8"?>

<set xmlns:android="http://schemas.android.com/apk/res/android">

<wbr><wbr>&lt;alpha/&gt;<br></wbr></wbr>

<wbr><wbr>&lt;scale/&gt;<br></wbr></wbr>

<wbr><wbr>&lt;translate/&gt;<br></wbr></wbr>

<wbr><wbr>&lt;rotate/&gt;<br></wbr></wbr>

</set>

Android动画解析--XML

<alpha>

<?xml version="1.0" encoding="utf-8"?>

<set xmlns:android="http://schemas.android.com/apk/res/android" >

<alpha

android:fromAlpha="0.1"

android:toAlpha="1.0"

android:duration="3000"

/>
