Android动画<第十一篇>：矢量图动画

在完成矢量图动画之前，必须了解矢量图在Android中的代码表示。Android Studio也可以制作自带的矢量图，或者导入svg格式的图片生成矢量图的代码。

我在Android Studio神器之Vector Asset这篇文章上已经做了简单的介绍。其中最为关键之处就是看懂矢量图的代码了。

（1）使用Vector Asset工具随意生成一个矢量图代码

矢量图的代码如下：

<vector android:height="24dp" android:tint="#FF3950"
    android:viewportHeight="24.0" android:viewportWidth="24.0"
    android:width="24dp" xmlns:android="http://schemas.android.com/apk/res/android">
    <path android:fillColor="#FF000000" android:pathData="M12,6v3l4,-4 -4,-4v3c-4.42,0 -8,3.58 -8,8 0,1.57 0.46,3.03 1.24,4.26L6.7,14.8c-0.45,-0.83 -0.7,-1.79 -0.7,-2.8 0,-3.31 2.69,-6 6,-6zM18.76,7.74L17.3,9.2c0.44,0.84 0.7,1.79 0.7,2.8 0,3.31 -2.69,6 -6,6v-3l-4,4 4,4v-3c4.42,0 8,-3.58 8,-8 0,-1.57 -0.46,-3.03 -1.24,-4.26z"/>
</vector>

图像如下：

图片.png

以上是使用Vector Asset工具生成的矢量图和矢量图代码。

android:width：表示是矢量图的宽度；
android:height：表示矢量图的高度；
android:viewportWidth：表示将矢量图的宽分成N等分，这里是分成24等分；
android:viewportHeight：表示将矢量图的高分成N等分，这里是分成24等分；
<path/>：表示一个路径
android:pathData：表示路径上的数据

<path> 可用的命令如下：

名称 解释
M = moveto(M X,Y) 将画笔移动到指定的坐标位置
L = lineto(L X,Y) 画直线到指定的坐标位置
H = horizontal lineto(H X) 画水平线到指定的X坐标位置
V = vertical lineto(V Y) 画垂直线到指定的Y坐标位置
C = curveto(C X1,Y1,X2,Y2,ENDX,ENDY) 三次贝赛曲线
S = smooth curveto(S X2,Y2,ENDX,ENDY) 同样三次贝塞尔曲线，更平滑
Q = quadratic Belzier curve(Q X,Y,ENDX,ENDY) 二次贝赛曲线
T = smooth quadratic Belzier curveto(T ENDX,ENDY) 同样二次贝塞尔曲线，更平滑
A = elliptical Arc(A RX,RY,XROTATION,large-arc-flag,sweep-flag,X,Y) 弧线
Z = closepath() 关闭路径

以上所有命令均允许小写字母。大写的字母是基于原点的坐标系(偏移量)，即绝对位置；小写字母是基于当前点坐标系(偏移量)，即相对位置。

（2）自己绘制一个矢量图

按照上面说到的path命令，我们完全可以自己绘制一个简单的矢量图

<vector
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:width="24dp"
    android:height="24dp"
    android:viewportHeight="24"
    android:viewportWidth="24">

    <path
        android:strokeWidth="1"
        android:fillColor="#ffffff"
        android:pathData="M10,10 L20,10 z"
        android:strokeColor="#FFFF00" />

</vector>

这是一条直线，如图：

图片.png

然而，更加复杂的矢量图绘制难度很大。

我们完全可以利用绘图工具制作一个SVG图片，然后使用AS生成代码，也可以使用AS自带的Vector Asset工具制作SVG图片。

然后，复杂的SVG生成的代码必然也是更加的复杂，这样就必须加深SVG的了解了。

（3）必须了解的API：VectorDrawable

VectorDrawable 一般是以 <vector> 为根标签定义的 XML 文件，<vector>标签下还可以有三种标签，分别是：<group>、<clip-path>、<path>，下面分别贴出这几种标签对应的属性。

<vector> 定义这个矢量图
android:name 矢量图的名字
android:width 矢量图的内部(intrinsic)宽度,支持所有Android系统支持的尺寸，通常使用dp
android:height 矢量图的内部(intrinsic)高度
android:viewportWidth 矢量图视图的宽度，视图就是矢量图path路径数据所绘制的虚拟画布
android:viewportHeight 矢量图视图的高度
android:tint 矢量图的tint颜色。默认是没有tint颜色的
android:tintMode 矢量图tint颜色的Porter-Duff混合模式，默认值为src_in。(src_in,src_over,src_atop,add,screen,multiply)
android:autoMirrored 设置当系统为RTL(right-to-left)布局的时候，是否自动镜像该图片。比如阿拉伯语
android:alpha 该图片的透明度属性
<group> 设置路径做动画的关键属性的
android:name 定义group的名字
android:rotation 定义该group的路径旋转多少度
android:pivotX 定义缩放和旋转该group时候的X参考点。该值相对于vector的viewport值来指定的。
android:pivotY 定义缩放和旋转该 group 时候的Y参考点。该值相对于vector的viewport值来指定的。
android:scaleX 定义X轴的缩放倍数
android:scaleY 定义Y轴的缩放倍数
android:translateX 定义移动X轴的位移。相对于vector的viewport值来指定的。
android:translateY 定义移动Y轴的位移。相对于vector的viewport值来指定的
<path> 路径
android:name 定义该path的名字，这样在其他地方可以通过名字来引用这个路径
android:pathData 和SVG中d元素一样的路径信息。
android:fillColor 定义填充路径的颜色，如果没有定义则不填充路径
android:strokeColor 定义如何绘制路径边框，如果没有定义则不显示边框
android:strokeWidth 定义路径边框的粗细尺寸
android:strokeAlpha 定义路径边框的透明度
android:fillAlpha 定义填充路径颜色的透明度
android:trimPathStart 从路径起始位置截断路径的比率，取值范围从0到1；注意从一半到起始动画为from-0.5-to-0
android:trimPathEnd 从路径结束位置截断路径的比率，取值范围从0到1；注意从一半到结束动画为from-0.5-to-1.0
android:trimPathOffset 设置路径截取的范围，取值范围从0到1
android:strokeLineCap 设置路径线帽的形状，取值为 butt, round, square.
android:strokeLineJoin 设置路径交界处的连接方式，取值为 miter,round,bevel.
android:strokeMiterLimit 设置斜角的上限
<clip-path> 定义当前绘制的剪切路径。注意，clip-path 只对当前的 group 和子 group 有效
android:name 定义clip-path的名字
android:pathData android:pathData的取值一样。

查看以上标签属性，我们发现<group>标签其实是为动画存在的，它本身对矢量图的绘制关系不大，而这个动画叫做矢量图动画。

那么，这个动画到底怎么实现呢？这里还需要了解一个接口：AnimatedVectorDrawable

（4）必须了解的API：AnimatedVectorDrawable

一般情况，表示一张矢量图不需要group标签，但是如果涉及到动画的话，可能就需要将一个或者多个路径进行分组。

AnimatedVectorDrawable通过ObjectAnimator或AnimatorSet对VectorDrawable的某个属性作一个矢量资源的动画。

AnimatedVectorDrawable就是矢量图动画，完成矢量图动画的要素有三，如下：

  • 一张矢量图，即以vector为标签的xml文件
  • 一个动画，objectAnimator或者AnimatorSet
  • AnimatedVectorDrawable，即以animated-vector为标签的xml文件
【举例】 实现左右箭头移动
41.gif

[第一步] 选择并自动生成一张矢量图

图片.png

生成的矢量图代码如下：

<vector
    android:height="24dp"
    android:tint="#3A2DFF"
    android:viewportHeight="24.0"
    android:viewportWidth="24.0"
    android:width="24dp"
    xmlns:android="http://schemas.android.com/apk/res/android">
    <path android:fillColor="#FF000000" android:pathData="M6.99,11L3,15l3.99,4v-3H14v-2H6.99v-3zM21,9l-3.99,-4v3H10v2h7.01v3L21,9z"/>
</vector>

[第二步] 拆分矢量图的两个箭头

矢量图的路径一般以Z（z）为结尾，根据这个特性，将矢量图拆分，拆分后的代码如下：

<vector
    android:height="240dp"
    android:tint="#3A2DFF"
    android:viewportHeight="24.0"
    android:viewportWidth="24.0"
    android:width="240dp"
    xmlns:android="http://schemas.android.com/apk/res/android">
    <group android:name="left">
        <path android:fillColor="#FF000000" android:pathData="M6.99,11L3,15l3.99,4v-3H14v-2H6.99v-3z"/>
    </group>
    <group android:name="right">
        <path android:fillColor="#FF000000" android:pathData="M21,9l-3.99,-4v3H10v2h7.01v3L21,9z"/>
    </group>
</vector>

[第三步] 准备好左右移动的动画

anim_left.xml

<?xml version="1.0" encoding="utf-8"?>
<objectAnimator
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="1000"
    android:repeatCount="infinite"
    android:propertyName="translateX"
    android:repeatMode="reverse"
    android:valueFrom="0"
    android:valueTo="-10">
</objectAnimator>

anim_right.xml

<?xml version="1.0" encoding="utf-8"?>
<objectAnimator
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="1000"
    android:repeatCount="infinite"
    android:propertyName="translateX"
    android:repeatMode="reverse"
    android:valueFrom="0"
    android:valueTo="10">
</objectAnimator>

[第四步] animated-vector编写

<?xml version="1.0" encoding="utf-8"?>
<animated-vector
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:drawable="@drawable/ic_swap_horiz_black_24dp">
    <target
        android:animation="@animator/anim_left"
        android:name="left">
    </target>
    <target
        android:animation="@animator/anim_right"
        android:name="right">
    </target>
</animated-vector>

其中，ic_swap_horiz_black_24dp为矢量图，animation为某动画，name和矢量图group标签的name对应。

[第五步] 设置src

<ImageView
    android:id="@+id/imageview"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerInParent="true"
    android:src="@drawable/animatedvector"/>

这里需要注意的是，如果设置background动画是无效的，需要设置src才有动画效果。

[第六步] 在代码中执行动画

        case R.id.button:
            Drawable drawable = ((ImageView)findViewById(R.id.imageview)).getDrawable();
            if (drawable instanceof Animatable){
                ((Animatable)drawable).start();
            }
            break;

但是，我们发现，完成一个矢量图动画需要建立多个xml文件，为了解决这个问题，可以将矢量图所用到的xml合并。

合并之后的xml如下：

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

    <aapt:attr name="android:drawable">

        <vector
            android:height="240dp"
            android:tint="#3A2DFF"
            android:viewportHeight="24.0"
            android:viewportWidth="24.0"
            android:width="240dp"
            xmlns:android="http://schemas.android.com/apk/res/android">
            <group android:name="left">
                <path android:fillColor="#FF000000" android:pathData="M6.99,11L3,15l3.99,4v-3H14v-2H6.99v-3z"/>
            </group>
            <group android:name="right">
                <path android:fillColor="#FF000000" android:pathData="M21,9l-3.99,-4v3H10v2h7.01v3L21,9z"/>
            </group>
        </vector>

    </aapt:attr>

    <target
        android:name="left">
        <aapt:attr name="android:animation">
            <objectAnimator
                xmlns:android="http://schemas.android.com/apk/res/android"
                android:duration="1000"
                android:repeatCount="infinite"
                android:propertyName="translateX"
                android:repeatMode="reverse"
                android:valueFrom="0"
                android:valueTo="-10">
            </objectAnimator>
        </aapt:attr>
    </target>
    <target
        android:name="right">

        <aapt:attr name="android:animation">
            <objectAnimator
                xmlns:android="http://schemas.android.com/apk/res/android"
                android:duration="1000"
                android:repeatCount="infinite"
                android:propertyName="translateX"
                android:repeatMode="reverse"
                android:valueFrom="0"
                android:valueTo="10">
            </objectAnimator>
        </aapt:attr>

    </target>
</animated-vector>

使用时，只要直接设置src并且执行动画即可。

<ImageView
    android:id="@+id/imageview"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerInParent="true"
    android:src="@drawable/animatedvector"/>



    Drawable drawable = ((ImageView)findViewById(R.id.imageview)).getDrawable();
    if (drawable instanceof Animatable){
        ((Animatable)drawable).start();
    }
（5）Shape Shifter工具的基本使用

[第一步] 打开网页在线编辑

https://shapeshifter.design/

图片.png

[第二步] 文件导入

图片.png

在本地选择一个SVG格式的矢量图或者Vector Drawble，如下：

导入之后的图片如下：

图片.png

[第三步] 查看文件

图片.png

点击图中的path，可以查看路径代码

图片.png

我们可以对这个路径进行修改，比如修改颜色

图片.png

再看，图中的网状线条，其实就是给矢量图分成了24等份方便坐标表示，这里的pathData就是根据坐标绘制轨迹的。

[第四步] 设置动画时长

图片.png

默认时长为300ms，点击修改动画时长为1秒。

图片.png

[第五步] 考虑好自己想要完成的动画，比如让整个图片进行旋转

结合group标签的知识，group标签的功能有：设置锚点、旋转、缩放、平移。

所以这里的旋转动画可以使用group标签来完成。

[第六步] 添加group标签，并将path添加到group标签中

图片.png

点击图中的“+”，添加一个group图层

图片.png

并将path拖入group中

图片.png

[第七步] 为group添加旋转动画

图片.png

如图，修改group的初始值，将锚点调整到图片中央（图片分成了24等份）

图片.png

点击右上角的“闹钟”图标，添加“rotation”字段

图片.png

在时间线区域不自动生成一个绿色时间线，正好与字段“rotation”字段平行，选中绿色时间线，绿色时间线变为蓝色时间线，在屏幕右上角出现该时间线的属性：

图片.png

startTime:开始时间
endTime：结束时间
interpolator：动画插值器
fromValue：动画的初始旋转角度
toValue：动画的结束旋转角度

图片.png

将动画时间改为1000ms，任意选择动画插值器，将动画角度变化范围调整为0~360度。

[第八步] 播放动画

197.gif

[第九步] 导出矢量图动画文件

图片.png

最后，直接导出文件即可，点击Export-->Animated Vector Drawable。

生成的代码如下：

<animated-vector
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:aapt="http://schemas.android.com/aapt">
    <aapt:attr name="android:drawable">
        <vector
            android:name="vector"
            android:width="240dp"
            android:height="240dp"
            android:viewportWidth="24"
            android:viewportHeight="24">
            <group
                android:name="group"
                android:pivotX="12"
                android:pivotY="12">
                <path
                    android:name="path"
                    android:pathData="M 12 6 L 12 9 L 16 5 L 12 1 L 12 4 C 7.58 4 4 7.58 4 12 C 4 13.57 4.46 15.03 5.24 16.26 L 6.7 14.8 C 6.25 13.97 6 13.01 6 12 C 6 8.69 8.69 6 12 6 Z M 18.76 7.74 L 17.3 9.2 C 17.74 10.04 18 10.99 18 12 C 18 15.31 15.31 18 12 18 L 12 15 L 8 19 L 12 23 L 12 20 C 16.42 20 20 16.42 20 12 C 20 10.43 19.54 8.97 18.76 7.74 Z"
                    android:fillColor="#ff0000"/>
            </group>
        </vector>
    </aapt:attr>
    <target android:name="group">
        <aapt:attr name="android:animation">
            <objectAnimator
                android:propertyName="rotation"
                android:duration="1000"
                android:valueFrom="0"
                android:valueTo="360"
                android:valueType="floatType"
                android:interpolator="@android:interpolator/fast_out_slow_in"/>
        </aapt:attr>
    </target>
</animated-vector>

设置这个矢量图动画

<ImageView
    android:id="@+id/imageview"
    android:layout_width="100dp"
    android:layout_height="100dp"
    android:layout_centerInParent="true"
    android:src="@drawable/yuan_anim"/>

最后再代码中播放动画

    Drawable drawable = ((ImageView)findViewById(R.id.imageview)).getDrawable();
    if (drawable instanceof Animatable){
        ((Animatable)drawable).start();
    }

演示效果如下：

198.gif
（6）Shape Shifter工具的Group属性

group标签除了旋转动画之外以，还有pivotX、pivotY、scaleX、scaleY、translateX、translateY等属性可以设置动态变化。

下面来一一举例：

[pivotX]和[pivotY]：设置锚点

上面图形的旋转动画的锚点的取值是（12,12），这个值从动画开始到动画结束没有发生变化，下面将锚点也随着时间动画变化呢？

图片.png
199.gif

[scaleX]和[scaleY]：动态缩放

图片.png
200.gif

[translateX]和[translateY]：动态平移

【略】

（7）Shape Shifter工具的Path属性

可被设置动画的字段有，pathData、fillColor、fillAlpha、strokeColor、strokeAlpha、strokeWidth、trimPathStart、trimPathEnd、trimPathOffset。

pathData： 和SVG中d元素一样的路径信息，可以将路径设置为动画开始和结束的取值；

【略】

fillColor： 定义填充路径的颜色，如果没有定义则不填充路径

201.gif

fillAlpha： 定义填充路径颜色的透明度

202.gif

strokeColor： 定义如何绘制路径边框，如果没有定义则不显示边框

203.gif

strokeAlpha： 定义路径边框的透明度

【略】

strokeWidth： 定义路径边框的粗细尺寸

【略】

trimPathStart： 从路径起始位置截断路径的比率，取值范围从0到1；

204.gif

这里需要注意的是，截断的是路径，而非填充色，上图的路径加上了边框，这个边框就是轨迹。

trimPathEnd： 从路径结束位置截断路径的比率，取值范围从0到1；

205.gif

这里需要注意的是，截断的是路径，而非填充色，上图的路径加上了边框，这个边框就是轨迹。

trimPathOffset： 设置起点路径和终点路径偏移量的范围，取值范围从0到1

206.gif

这里需要注意的是，截断的是路径，而非填充色，上图的路径加上了边框，这个边框就是轨迹。

（8）Shape Shifter工具自带Demo解析

[Demo：Play to Pause]

207.gif
图片.png

如图所示，完成这个动画需要两个字段的动画：rotation、pathData

图片.png

旋转动画的字段在group标签上，取值范围是0~90度。

图片.png

路径动画的字段在path标签上，去世范围是：从M 8 5 L 8 12 L 19 12 L 19 12 L 8 5 M 8 12 L 8 19 L 19 12 L 19 12 L 8 12到M 5 6 L 5 10 L 19 10 L 19 6 L 5 6 M 5 14 L 5 18 L 19 18 L 19 14 L 5 14。

在右上角有一个编辑按钮，点击进入编辑界面

图片.png

编辑界面顶部有几个按钮：
加号按钮的作用是添加一个点；
剪刀按钮的作用是画一条直线分割一个路径，使路径一分为二；
双向箭头按钮的作用是匹配动画前后的路径；
双向箭头后面的按钮的作用是将选中的路径上的点反转，动画前后的点必须一一对应，路径上的点反转之后动画也会发生改变；
左箭头按钮的作用是将路径的点依次向上移动一个单位；
右箭头按钮的作用是将路径的点依次向下移动一个单位；

总之，为了将两个毫不相关的路径完成动画效果，必须将两个路径紧密的联系在一起，这个编辑界面可以将两个毫不相关的路径紧密的联系在一起，最终完成动画。

代码如下：

<animated-vector
