FloatValueHolder

open class FloatValueHolder

kotlin.Any
↳	androidx.dynamicanimation.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 FloatValueHolder#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. FloatValueHolder floatValueHolder = new FloatValueHolder(20f); FlingAnimation anim = new FlingAnimation(floatValueHolder).setStartVelocity(5000); anim.start();

Summary
