B4A Library SpeedView

A Wrap for this Github project. Posting the following:

1. B4A sample project
2. B4A library files
3. Java Code - amend it to your liking.

Sample code:
#Region  Project Attributes
    #ApplicationLabel: SpeedView
    #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.

    Dim t As Timer

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 sv1 As SpeedView
End Sub

Sub Activity_Create(FirstTime As Boolean)
    'Do not forget to load the layout file created with the visual designer. For example:

    t.Initialize("t", 1000)

    sv1.IndicatorColor = Colors.White
    sv1.TextColor = Colors.White
    sv1.LowSpeedColor = Colors.Yellow
    sv1.MediumSpeedColor = Colors.Cyan
    sv1.HighSpeedColor = Colors.Magenta
    sv1.MaxSpeed = 200
    sv1.CenterCircleColor = Colors.Green
    sv1.MarkColor = Colors.Red
    sv1.WithTremble = False

End Sub

Sub Activity_Resume

    t.Enabled = True

End Sub

Sub Activity_Pause (UserClosed As Boolean)

    t.Enabled = False

End Sub

Sub t_tick

    sv1.speedTo_2(Rnd(0, 201), 400)

End Sub
