FloatValueHolder


class FloatValueHolder


FloatValueHolder holds a float value. FloatValueHolder provides a setter and a getter ( i.e. setValue 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. 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.
FloatValueHolder floatValueHolder = new FloatValueHolder(20f);
FlingAnimation anim = new FlingAnimation(floatValueHolder).setStartVelocity(5000);
anim.start();
