AnimatedVectorDrawable

Kotlin |Java

open class AnimatedVectorDrawable : Drawable, Animatable2

kotlin.Any
↳	android.graphics.drawable.Drawable
	↳	android.graphics.drawable.AnimatedVectorDrawable

This class animates properties of a android.graphics.drawable.VectorDrawable with animations defined using android.animation.ObjectAnimator or android.animation.AnimatorSet.

Starting from API 25, AnimatedVectorDrawable runs on RenderThread (as opposed to on UI thread for earlier APIs). This means animations in AnimatedVectorDrawable can remain smooth even when there is heavy workload on the UI thread. Note: If the UI thread is unresponsive, RenderThread may continue animating until the UI thread is capable of pushing another frame. Therefore, it is not possible to precisely coordinate a RenderThread-enabled AnimatedVectorDrawable with UI thread animations. Additionally, android.graphics.drawable.Animatable2.AnimationCallback#onAnimationEnd(Drawable) will be called the frame after the AnimatedVectorDrawable finishes on the RenderThread.

AnimatedVectorDrawable can be defined in either three separate XML files, or one XML.

Define an AnimatedVectorDrawable in three separate XML files

XML for the VectorDrawable containing properties to be animated

Animations can be performed on the animatable attributes in android.graphics.drawable.VectorDrawable. These attributes will be animated by android.animation.ObjectAnimator. The ObjectAnimator's target can be the root element, a group element or a path element. The targeted elements need to be named uniquely within the same VectorDrawable. Elements without animation do not need to be named.

Here are all the animatable attributes in android.graphics.drawable.VectorDrawable:

Element Name	Animatable attribute name
<vector>	alpha
<group>	rotation
	pivotX
	pivotY
	scaleX
	scaleY
	translateX
	translateY
<path>	pathData
	fillColor
	strokeColor
	strokeWidth
	strokeAlpha
	fillAlpha
	trimPathStart
	trimPathEnd
	trimPathOffset
<clip-path>	pathData

Below is an example of a VectorDrawable defined in vectordrawable.xml. This VectorDrawable is referred to by its file name (not including file suffix) in the AnimatedVectorDrawable XML example.

<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>

XML for AnimatedVectorDrawable

An AnimatedVectorDrawable element has a VectorDrawable attribute, and one or more target element(s). The target element can specify its target by android:name attribute, and link the target with the proper ObjectAnimator or AnimatorSet by android:animation attribute.
The following code sample defines an AnimatedVectorDrawable. Note that the names refer to the groups and paths in the VectorDrawable XML above.
```
<animated-vector xmlns:android="http://schemas.android.com/apk/res/android"
      android:drawable="@drawable/vectordrawable" >
      <target
          android:name="rotationGroup"
          android:animation="@animator/rotation" />
      <target
          android:name="v"
          android:animation="@animator/path_morph" />
  </animated-vector>
  
```

XML for Animations defined using ObjectAnimator or AnimatorSet

From the previous example of AnimatedVectorDrawable, two animations were used: rotation.xml and path_morph.xml.

rotation.xml rotates the target group from 0 degree to 360 degrees over 6000ms:

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

path_morph.xml morphs the path from one shape into the other. Note that the paths must be compatible for morphing. Specifically, the paths must have the same commands, in the same order, and must have the same number of parameters for each command. It is recommended to store path strings as string resources for reuse.

<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>

Define an AnimatedVectorDrawable all in one XML file

Since the AAPT tool supports a new format that bundles several related XML files together, we can merge the XML files from the previous examples into one XML file:

<animated-vector xmlns:android="http://schemas.android.com/apk/res/android"
                   xmlns:aapt=&quothttp://schemas.android.com/aapt" >
      <aapt:attr name="android:drawable">
          <vector
              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>
      </aapt:attr>
 
      <target android:name="rotationGroup"> *
          <aapt:attr name="android:animation">
              <objectAnimator
              android:duration="6000"
              android:propertyName="rotation"
              android:valueFrom="0"
              android:valueTo="360" />
          </aapt:attr>
      </target>
 
      <target android:name="v" >
          <aapt:attr name="android:animation">
              <set>
                  <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>
          </aapt:attr>
       </target>
  </animated-vector>

Inherited functions

From class Drawable

`Unit`	`clearColorFilter()` Removes the color filter for this drawable.
`Rect`	`copyBounds()` Return a copy of the drawable's bounds in a new Rect. This returns the same values as getBounds(), but the returned object is guaranteed to not be changed later by the drawable (i.e. it retains no reference to this rect). If the caller already has a Rect allocated, call copyBounds(rect).
`Unit`	`copyBounds(bounds: Rect)` Return a copy of the drawable's bounds in the specified Rect (allocated by the caller). The bounds specify where this will draw when its draw() method is called.
`Drawable?`	`createFromPath(pathName: String!)` Create a drawable from file path name.
`Drawable?`	`createFromResourceStream(res: Resources?, value: TypedValue?, is: InputStream?, srcName: String?)` Create a drawable from an inputstream, using the given resources and value to determine density information.
`Drawable?`	`createFromResourceStream(res: Resources?, value: TypedValue?, is: InputStream?, srcName: String?, opts: BitmapFactory.Options?)` Create a drawable from an inputstream, using the given resources and value to determine density information.
`Drawable?`	`createFromStream(is: InputStream?, srcName: String?)` Create a drawable from an inputstream
`Drawable`	`createFromXml(r: Resources, parser: XmlPullParser)` Create a drawable from an XML document. For more information on how to create resources in XML, see Drawable Resources.
`Drawable`	`createFromXml(r: Resources, parser: XmlPullParser, theme: Resources.Theme?)` Create a drawable from an XML document using an optional `Theme`. For more information on how to create resources in XML, see Drawable Resources.
`Drawable`	`createFromXmlInner(r: Resources, parser: XmlPullParser, attrs: AttributeSet)` Create from inside an XML document. Called on a parser positioned at a tag in an XML document, tries to create a Drawable from that tag. Returns null if the tag is not a valid drawable.
`Drawable`	`createFromXmlInner(r: Resources, parser: XmlPullParser, attrs: AttributeSet, theme: Resources.Theme?)` Create a drawable from inside an XML document using an optional `Theme`. Called on a parser positioned at a tag in an XML document, tries to create a Drawable from that tag. Returns `null` if the tag is not a valid drawable.
`Rect`	`getBounds()` Return the drawable's bounds Rect. Note: for efficiency, the returned object may be the same object stored in the drawable (though this is not guaranteed), so if a persistent copy of the bounds is needed, call copyBounds(rect) instead. You should also not change the object returned by this method as it may be the same object stored in the drawable.
`Drawable.Callback?`	`getCallback()` Return the current `Callback` implementation attached to this Drawable.
`Drawable`	`getCurrent()`
`Rect`	`getDirtyBounds()` Return the drawable's dirty bounds Rect. Note: for efficiency, the returned object may be the same object stored in the drawable (though this is not guaranteed). By default, this returns the full drawable bounds. Custom drawables may override this method to perform more precise invalidation.
`Unit`	`getHotspotBounds(outRect: Rect)` Populates `outRect` with the hotspot bounds.
`Int`	`getLayoutDirection()` Returns the resolved layout direction for this Drawable.
`Int`	`getLevel()` Retrieve the current level.
`Int`	`getMinimumHeight()` Returns the minimum height suggested by this Drawable. If a View uses this Drawable as a background, it is suggested that the View use at least this value for its height. (There will be some scenarios where this will not be possible.) This value should INCLUDE any padding.
`Int`	`getMinimumWidth()` Returns the minimum width suggested by this Drawable. If a View uses this Drawable as a background, it is suggested that the View use at least this value for its width. (There will be some scenarios where this will not be possible.) This value should INCLUDE any padding.
`Boolean`	`getPadding(padding: Rect)` Return in padding the insets suggested by this Drawable for placing content inside the drawable's bounds. Positive values move toward the center of the Drawable (set Rect.inset).
`IntArray`	`getState()` Describes the current state, as a union of primitive states, such as `android.R.attr#state_focused`, `android.R.attr#state_selected`, etc. Some drawables may modify their imagery based on the selected state.
`Region?`	`getTransparentRegion()` Returns a Region representing the part of the Drawable that is completely transparent. This can be used to perform drawing operations, identifying which parts of the target will not change when rendering the Drawable. The default implementation returns null, indicating no transparent region; subclasses can optionally override this to return an actual Region if they want to supply this optimization information, but it is not required that they do so.
`Boolean`	`hasFocusStateSpecified()` Indicates whether this drawable has at least one state spec explicitly specifying `android.R.attr#state_focused`. Note: A View uses a `Drawable` instance as its background and it changes its appearance based on a state. On keyboard devices, it should specify its `android.R.attr#state_focused` to make sure the user knows which view is holding the focus.
`Unit`	`inflate(r: Resources, parser: XmlPullParser, attrs: AttributeSet)` Inflate this Drawable from an XML resource. Does not apply a theme.
`Unit`	`invalidateSelf()` Use the current `Callback` implementation to have this Drawable redrawn. Does nothing if there is no Callback attached to the Drawable.
`Boolean`	`isAutoMirrored()` Tells if this Drawable will be automatically mirrored when its layout direction is RTL right-to-left. See `android.util.LayoutDirection`.
`Boolean`	`isFilterBitmap()`
`Boolean`	`isProjected()` Whether this drawable requests projection. Indicates that the `android.graphics.RenderNode` this Drawable will draw into should be drawn immediately after the closest ancestor RenderNode containing a projection receiver.
`Boolean`	`isVisible()`
`Unit`	`jumpToCurrentState()` If this Drawable does transition animations between states, ask that it immediately jump to the current state and skip any active animations.
`Int`	`resolveOpacity(op1: Int, op2: Int)` Return the appropriate opacity value for two source opacities. If either is UNKNOWN, that is returned; else, if either is TRANSLUCENT, that is returned; else, if either is TRANSPARENT, that is returned; else, OPAQUE is returned. This is to help in implementing `getOpacity`.
`Unit`	`scheduleSelf(what: Runnable, when: Long)` Use the current `Callback` implementation to have this Drawable scheduled. Does nothing if there is no Callback attached to the Drawable.
`Unit`	`setAutoMirrored(mirrored: Boolean)` Set whether this Drawable is automatically mirrored when its layout direction is RTL (right-to left). See `android.util.LayoutDirection`.
`Unit`	`setBounds(bounds: Rect)` Specify a bounding rectangle for the Drawable. This is where the drawable will draw when its draw() method is called.
`Unit`	`setBounds(left: Int, top: Int, right: Int, bottom: Int)` Specify a bounding rectangle for the Drawable. This is where the drawable will draw when its draw() method is called.
`Unit`	`setCallback(cb: Drawable.Callback?)` Bind a `Callback` object to this Drawable. Required for clients that want to support animated drawables.
`Unit`	`setChangingConfigurations(configs: Int)` Set a mask of the configuration parameters for which this drawable may change, requiring that it be re-created.
`Unit`	`setColorFilter(color: Int, mode: PorterDuff.Mode)` Specify a color and Porter-Duff mode to be the color filter for this drawable. Convenience for `setColorFilter(android.graphics.ColorFilter)` which constructs a `PorterDuffColorFilter`. Note: Setting a color filter disables `tint`.
`Unit`	`setDither(dither: Boolean)` Set to true to have the drawable dither its colors when drawn to a device with fewer than 8-bits per color component.
`Unit`	`setFilterBitmap(filter: Boolean)` Set to true to have the drawable filter its bitmaps with bilinear sampling when they are scaled or rotated. This can improve appearance when bitmaps are rotated. If the drawable does not use bitmaps, this call is ignored.
`Boolean`	`setLayoutDirection(layoutDirection: Int)` Set the layout direction for this drawable. Should be a resolved layout direction, as the Drawable has no capacity to do the resolution on its own.
`Boolean`	`setLevel(level: Int)` Specify the level for the drawable. This allows a drawable to vary its imagery based on a continuous controller, for example to show progress or volume level. If the new level you are supplying causes the appearance of the Drawable to change, then it is responsible for calling `invalidateSelf` in order to have itself redrawn, and true will be returned from this function.
`Boolean`	`setState(stateSet: IntArray)` Specify a set of states for the drawable. These are use-case specific, so see the relevant documentation. As an example, the background for widgets like Button understand the following states: [`android.R.attr#state_focused`, `android.R.attr#state_pressed`]. If the new state you are supplying causes the appearance of the Drawable to change, then it is responsible for calling `invalidateSelf` in order to have itself redrawn, and true will be returned from this function. Note: The Drawable holds a reference on to stateSet until a new state array is given to it, so you must not modify this array during that time.
`Unit`	`setTint(tintColor: Int)` Specifies tint color for this drawable. A Drawable's drawing content will be blended together with its tint before it is drawn to the screen. This functions similarly to `setColorFilter(int,android.graphics.PorterDuff.Mode)`. To clear the tint, pass `null` to `setTintList(android.content.res.ColorStateList)`. Note: Setting a color filter via `setColorFilter(android.graphics.ColorFilter)` or `setColorFilter(int,android.graphics.PorterDuff.Mode)` overrides tint.
`Unit`	`setTintMode(tintMode: PorterDuff.Mode?)` Specifies a tint blending mode for this drawable. Defines how this drawable's tint color should be blended into the drawable before it is drawn to screen. Default tint mode is `PorterDuff.Mode.SRC_IN`. Note: Setting a color filter via `setColorFilter(android.graphics.ColorFilter)` or `setColorFilter(int,android.graphics.PorterDuff.Mode)` overrides tint.
`Unit`	`unscheduleSelf(what: Runnable)` Use the current `Callback` implementation to have this Drawable unscheduled. Does nothing if there is no Callback attached to the Drawable.
