API

Method Description
void setListener(Listener listener) Add a listener that will be invoked when the user interacts with the view
void setRadiansAngle(double radians) Set the rotation angle in radians
void setDegreesAngle(double degrees) Set the rotation angle in degrees
void setCompleteTurnFraction(double fraction) Set the rotation angle in fraction, where 0f = 0°, 1.0f = 360°
double getRadiansAngle() Get the rotation angle in radians (-2π, 2π)
double getDegreesAngle() Get the rotation angle in degrees (-360°, 360°)
double getCompleteTurnFraction() Get the roatation angle in fraction (0f, 1.0f), where 0f = 0°, 1.0f = 360°
void setOnlyPositiveValues(boolean onlyPositiveValues) When true, all rotation getters return only positive values, in xml: app:onlyPositiveValues, default: false
void setMarksCount(int marksCount) Set the total number of marks on the wheel, in xml: app:marksCount
