FloatValueHolder
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
