B4A Library CircularSeekBar

The attached project wraps this Github project. Library files (JAR & XML) are in the /files folder of the B4A project. Copy them to your additional libraries folder. Also posting the Java source code.

The left hand view demonstrates most of the properties. The right hand view is based on the default properties.

Thanks teacher...

If the progress is changed as a result, then any listener will receive a onProgressChanged event.

Couldn't get this event to work.

Without Changed or Touch events this control is useless IMHO.

Use the lib files attached and add the following code to the B4A project:

Sub csb1_value_changed
  
    Log("csb1 value = " & csb1.Progress)
  
End Sub

Sub csb2_value_changed
  
    Log("csb2 value = " & csb2.Progress)
  
End Sub

Amend the initialize lines of code to:

csb1.Initialize("csb1")
csb2.Initialize("csb2")

The xxxx_value_changed event will be raised regardless of the progress being set via B4A code or via touch.
