Android SVG动画

SVG文件我是用的Adobe Illustrator的官方样例文件，当然也可以自己画，但是没有那么漂亮的创意就对了

首先导入svg文件
右键drawable文件new-Vector Asset，选中Local File，然后选择你本地的SVG文件，当然也可以选择Clip Art直接用Android预设图片

导入之后就是一个路径的列表，因为图片比较复杂，所以路径也会比较多

然后给每一个path路径命名，到时候用来控制动画，这里我就简单加了下命名

然后就是配置动画列表了
新建一个drawable文件，使用animated-vector标签,把刚才命名的路径都加上一个动画配置
anim_show.xml

<?xml version="1.0" encoding="utf-8"?>
<animated-vector xmlns:android="http://schemas.android.com/apk/res/android"
    android:drawable="@drawable/ic_artboard_4">

    <target android:name="a1" android:animation="@animator/anim_default_fill" />
    <target android:name="a2" android:animation="@animator/anim_default_fill" />
    <target android:name="a3" android:animation="@animator/anim_default_fill" />
    <target android:name="a4" android:animation="@animator/anim_default_fill" />
    <target android:name="a5" android:animation="@animator/anim_default_fill" />
    <target android:name="a6" android:animation="@animator/anim_default_fill" />
    <target android:name="a7" android:animation="@animator/anim_default_fill" />

    <target android:name="a19" android:animation="@animator/anim_default_fill" />
    <target android:name="a20" android:animation="@animator/anim_default_fill" />
    <target android:name="a21" android:animation="@animator/anim_default_fill" />
    <target android:name="a22" android:animation="@animator/anim_default_fill" />

    <target android:name="a25" android:animation="@animator/anim_default_fill" />
    <target android:name="a26" android:animation="@animator/anim_default_fill" />
    <target android:name="a27" android:animation="@animator/anim_default_fill" />
    <target android:name="a28" android:animation="@animator/anim_default_fill" />
    <target android:name="a29" android:animation="@animator/anim_default_fill" />
    <target android:name="a30" android:animation="@animator/anim_default_fill" />
    <target android:name="a31" android:animation="@animator/anim_default_fill" />
    <target android:name="a32" android:animation="@animator/anim_default_fill" />

    <target android:name="a41" android:animation="@animator/anim_default_fill" />
    <target android:name="a42" android:animation="@animator/anim_default_fill" />
    <target android:name="a43" android:animation="@animator/anim_default_fill" />
    <target android:name="a44" android:animation="@animator/anim_default_fill" />
    <target android:name="a45" android:animation="@animator/anim_default_fill" />
    <target android:name="a46" android:animation="@animator/anim_default_fill" />
    <target android:name="a47" android:animation="@animator/anim_default_fill" />
    <target android:name="a48" android:animation="@animator/anim_default_fill" />
    <target android:name="a49" android:animation="@animator/anim_default_fill" />
    <target android:name="a50" android:animation="@animator/anim_default_fill" />
    <target android:name="a51" android:animation="@animator/anim_default_fill" />
    <target android:name="a52" android:animation="@animator/anim_default_fill" />
    <target android:name="a53" android:animation="@animator/anim_default_fill" />
    <target android:name="a54" android:animation="@animator/anim_default_fill" />
    <target android:name="a55" android:animation="@animator/anim_default_fill" />

</animated-vector>

动画是一个绘制路径的动画，就是从0开始顺着路径绘制
在res新建一个animator的文件夹，再新建一个xml文件
propertyName:从路径结束位置截断路径的比率，取值范围从 0 到1

<?xml version="1.0" encoding="utf-8"?>
<objectAnimator
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:propertyName="trimPathEnd" 
    android:valueFrom="0"
    android:valueTo="1"
    android:valueType="floatType"
    android:duration="5000"
    android:interpolator="@android:interpolator/linear_out_slow_in" />

然后ImageView就可以设置动画了

anim1 = (AnimatedVectorDrawable) getResources().getDrawable(R.drawable.anim_show,null);
imageView.setImageDrawable(anim1);
anim1.start();

具体效果
