Android Question B4XSeekBar Steps

[Lucas Eduardo]

Hello, i would like to know if is there a way to scrolls the seek bar in steps like 10 to 10 with max 100 using the SeekBar of XUIViews?

The effect is not smooth, if you drag the knob.

Sub B4XSeekBar1_ValueChanged (Value As Int)
    B4XSeekBar1.Value = Round (Value/10) * 10
    Log("Value: " & B4XSeekBar1.Value)
End Sub

You can get it to snap on mouse release by adding a listener to the basepane of the seekbar:

    Dim Jo As JavaObject = B4XSeekBar1.mBase
    Dim O As Object = Jo.CreateEventFromUI("javafx.event.EventHandler","Seekbar",Null)
    Jo.RunMethod("setOnMouseReleased",Array(O))

Then adding Jorge's code to the mouse released event callback:

Sub SeekBar_Event (MethodName As String, Args() As Object) As Object
    B4XSeekBar1.Value = Round (B4XSeekBar1.Value/10) * 10
    Log("Value: " & B4XSeekBar1.Value)
End Sub

Not much different but it's a little nicer experience maybe.

Ooops sorry, just realized it's B4a, will look for the correct code.

Hmm, sorry it seems that this option is not available for B4a, the touch listener is in use by the Seekbar, we can't listen to it and use the seekbar.

XUI Views V2.18 - B4XSeekBar.Interval field / designer property - Allows changing the values interval. Default value is 1.
