MotionSpec

open class MotionSpec

A motion spec contains multiple named motion timings.

Inflate an instance of MotionSpec from XML by creating a Property Animation resource in res/animator. The file must contain an <objectAnimator> or a <set> of object animators.

This class will store a map of String keys to MotionTiming values. Each animator's android:propertyName attribute will be used as the key, while the other attributes android:startOffset, android:duration, android:interpolator, android:repeatCount, and android:repeatMode will be used to create the MotionTiming instance.

A motion spec resource can either be an or a of multiple .


<set xmlns:android="http://schemas.android.com/apk/res/android">
  <objectAnimator
      android:propertyName="alpha"
      android:startOffset="0"
      android:duration="100"
      android:interpolator="@interpolator/mtrl_fast_out_slow_in"/>
  <objectAnimator
      android:propertyName="translation"
      android:startOffset="50"
      android:duration="150"/>
</set>
