android.support.animation.FloatValueHolder
FloatValueHolder holds a float value. FloatValueHolder provides a setter and a getter (
i.e. setValue(float) and getValue()) to access this float value. Animations can
be performed on a FloatValueHolder instance. During each frame of the animation, the
FloatValueHolder will have its value updated via setValue(float). The caller can
obtain the up-to-date animation value via getValue().
Here is an example for creating a FlingAnimation with a FloatValueHolder:
// Create a fling animation with an initial velocity of 5000 (pixel/s) and an initial position// of 20f.FloatValueHolderfloatValueHolder=newFloatValueHolder(20f);FlingAnimationanim=newFlingAnimation(floatValueHolder).setStartVelocity(5000);anim.start();
