ArcMotion

public class ArcMotion
extends PathMotion

A PathMotion that generates a curved path along an arc on an imaginary circle containing the two points. If the horizontal distance between the points is less than the vertical distance, then the circle's center point will be horizontally aligned with the end point. If the vertical distance is less than the horizontal distance then the circle's center point will be vertically aligned with the end point.

When the two points are near horizontal or vertical, the curve of the motion will be small as the center of the circle will be far from both points. To force curvature of the path, setMinimumHorizontalAngle(float) and setMinimumVerticalAngle(float) may be used to set the minimum angle of the arc between two points.

This may be used in XML as an element inside a transition.

<changeBounds>
   <arcMotion android:minimumHorizontalAngle="15"
              android:minimumVerticalAngle="0"
              android:maximumAngle="90"/>
 </changeBounds>
