Class Overview

This class uses ObjectAnimator and AnimatorSet to animate the properties of a VectorDrawable to create an animated drawable.

AnimatedVectorDrawable are normally defined as 3 separate XML files.

First is the XML file for VectorDrawable. Note that we allow the animation happen on the group's attributes and path's attributes, which requires they are uniquely named in this xml file. Groups and paths without animations do not need names.

Here is a simple VectorDrawable in this vectordrawable.xml file.

 <vector xmlns:android="http://schemas.android.com/apk/res/android"
     android:height="64dp"
     android:width="64dp"
     android:viewportHeight="600"
     android:viewportWidth="600" >
     <group
         android:name="rotationGroup"
         android:pivotX="300.0"
         android:pivotY="300.0"
         android:rotation="45.0" >
         <path
             android:name="v"
             android:fillColor="#000000"
             android:pathData="M300,70 l 0,-70 70,70 0,0 -70,70z" />
     </group>
 </vector>

Second is the AnimatedVectorDrawable's xml file, which defines the target VectorDrawable, the target paths and groups to animate, the properties of the path and group to animate and the animations defined as the ObjectAnimators or AnimatorSets.

Here is a simple AnimatedVectorDrawable defined in this avd.xml file. Note how we use the names to refer to the groups and paths in the vectordrawable.xml.

 <animated-vector xmlns:android="http://schemas.android.com/apk/res/android"
   android:drawable="@drawable/vectordrawable" >
     <target
         android:name="rotationGroup"
         android:animation="@anim/rotation" />
     <target
         android:name="v"
         android:animation="@anim/path_morph" />
 </animated-vector>

Last is the Animator xml file, which is the same as a normal ObjectAnimator or AnimatorSet. To complete this example, here are the 2 animator files used in avd.xml: rotation.xml and path_morph.xml.

Here is the rotation.xml, which will rotate the target group for 360 degrees.

 <objectAnimator
     android:duration="6000"
     android:propertyName="rotation"
     android:valueFrom="0"
     android:valueTo="360" />

Here is the path_morph.xml, which will morph the path from one shape to the other. Note that the paths must be compatible for morphing. In more details, the paths should have exact same length of commands , and exact same length of parameters for each commands. Note that the path string are better stored in strings.xml for reusing.

 <set xmlns:android="http://schemas.android.com/apk/res/android">
     <objectAnimator
         android:duration="3000"
         android:propertyName="pathData"
         android:valueFrom="M300,70 l 0,-70 70,70 0,0   -70,70z"
         android:valueTo="M300,70 l 0,-70 70,0  0,140 -70,0 z"
         android:valueType="pathType"/>
 </set>

XML Attributes

android:animation

The animation for the target path, group or vector drawable

Must be a reference to another resource, in the form "@[+][package:]type:name" or to a theme attribute in the form "?[package:][type:]name".

This corresponds to the global attribute resource symbol animation.

Related Methods

android:drawable

The static vector drawable.

Must be a reference to another resource, in the form "@[+][package:]type:name" or to a theme attribute in the form "?[package:][type:]name".

This corresponds to the global attribute resource symbol drawable.

Related Methods

android:name

The name of the target path, group or vector drawable

Must be a string value, using '\\;' to escape characters such as '\\n' or '\\uxxxx' for a unicode character.

This may also be a reference to a resource (in the form "@[package:]type:name") or theme attribute (in the form "?[package:][type:]name") containing a value of this type.

This corresponds to the global attribute resource symbol name.

res	Resources used to resolve attribute values
parser	XML parser from which to inflate this Drawable
attrs	Base set of attribute values
theme	Theme to apply, may be null

x	The X coordinate of the center of the hotspot
y	The Y coordinate of the center of the hotspot

visible	Set to true if visible, false if not.
restart	You can supply true here to force the drawable to behave as if it has just become visible, even if it had last been set visible. Used for example to force animations to restart.
