Source

    overlapDuration: f32,

Available on crate feature api-12 only.
Expand description

Creates a responsive spring animation curve. It is a special case of springMotion, with the only difference in the default values. It can be used together with springMotion.

Note: The animation duration is subject to the curve parameters, rather than the duration parameter in animation or animateTo.

§Arguments

  • response - Indicates the duration of one complete oscillation.

  • dampingFraction - Indicates the damping coefficient.

0 and < 1: underdamped. In this case, the spring overshoots the equilibrium position. 1: critically damped. 1: overdamped. In this case, the spring approaches equilibrium gradually.

  • overlapDuration - Indicates the duration for animations to overlap. When animations overlap, the response values of these animations will transit smoothly over this duration if they are different.

§Returns

  • Returns the pointer to the interpolation object of the curve. Returns NULL if a parameter error occurs.

Available since API-level: 12
