B4A Library HorizontalWheelView

A wrap for this Github project. Posting:
1. B4A project
2. B4A library files - copy them to your additional library folder.
3. The Java code


Sample code:
#Region  Project Attributes
    #ApplicationLabel: HorizontalWheel
    #VersionCode: 1
    'SupportedOrientations possible values: unspecified, landscape or portrait.
    #SupportedOrientations: unspecified
    #CanInstallToExternalStorage: False
#End Region

#Region  Activity Attributes
    #FullScreen: False
    #IncludeTitle: True
#End Region

Sub Process_Globals
    'These global variables will be declared once when the application starts.
    'These variables can be accessed from all modules.

End Sub

Sub Globals
    'These global variables will be redeclared each time the activity is created.
    'These variables can only be accessed from this module.

    Private hwv1 As HorizontalWheelView
    Private Label1 As Label
    Private Label2 As Label
End Sub

Sub Activity_Create(FirstTime As Boolean)
    'Do not forget to load the layout file created with the visual designer. For example:
    hwv1.ActiveColor = Colors.green
    hwv1.NormalColor = Colors.Yellow
    hwv1.DegreesAngle = 60
    'hwv1.RadiansAngle = 3.14159

End Sub

Sub Activity_Resume

End Sub

Sub Activity_Pause (UserClosed As Boolean)

End Sub

Sub hwv1_rotation_changed(angleradians As Double)
    Log("angle in radians = " & angleradians)
    Label1.Text = "Radians = " & NumberFormat(angleradians, 1, 2)
    Label2.Text = "Degrees = " & NumberFormat(360*angleradians/(2*cPI), 1, 2)
End Sub
