Android Tutorial [B4X] B4XPlusMinus - Spinner / wheel alternative

B4XPlusMinus is a cross platform control introduced in XUI Views v2.05: https://www.b4x.com/android/forum/threads/b4x-xui-views-cross-platform-views-and-dialogs.100836/

As you can see in the above image it supports three different formations: horizontal, vertical and bottom. The bottom formation is useful with smaller controls to prevent the user finger from hiding the value.

There are two ways to set the values:

SetStringItems - A list or array with the items:

pm.SetStringItems(Array("aaa", "bbb"))

SetNumericRange - A numeric range:

pm.SetNumericRange(1, 100, 2) '1 - 100 with interval of 2.

Numeric values are converted to strings with the help of B4XFormatter.
The controls color and text size is set with the designer. Other options:

Cyclic - Whether to move to the first item after the last item.
Rapid - Whether to allow rapid changes with long clicks. Note that you can change the durations used for the rapid effect (RapidPeriod1 and RapidPeriod2 fields - default values are 1000ms and 30ms).

Example is attached.

Using XUI Views v2.05?

yes, downloaded 5 mins. ago.

 

[Erel]

Can you post the unfiltered logs?

Have you copied it to the internal libraries folder?

 

[Mahares]

I downloaded: B4X Views but the library pane still shows: version 2.00 after refresh
EDIT: I had it in the additional lib folder. All is good now

Have you copied it to the internal libraries folder?

[Alexander Stolte]

Where does b4a.exampleggsdg come from?

i downloaded the example project above, change the paketname to this, because i have a other paket with "b4a.example" on the phone.

Which version of B4A are you using?

9.00

Clean the project (Ctrl + P). It will fix it. This issue is fixed in v9.01: https://www.b4x.com/android/forum/threads/104974/#content

Got it working in B4J

Sub Process_Globals
    Private fx As JFX
    Private mainForm As Form
    Private B4XPlusMinus1 As B4XPlusMinus
    Private B4XPlusMinus2 As B4XPlusMinus
    Private B4XPlusMinus3 As B4XPlusMinus
    Private B4XPlusMinus4 As B4XPlusMinus
End Sub

Sub AppStart (Form1 As Form, Args() As String)
    mainForm = Form1
    mainForm.RootPane.LoadLayout("frmMain") 'Load the layout file.
    mainForm.Show
    
    B4XPlusMinus1.SetStringItems(File.ReadList(File.DirAssets, "cities.txt"))
    B4XPlusMinus1.Increment
    
    Dim clrs As List
    clrs.Initialize
    clrs.Add("Red")
    clrs.Add("Green")
    clrs.Add("Blue")
    B4XPlusMinus2.SetStringItems(clrs)
    B4XPlusMinus2.SelectedValue = clrs.Get(0)
    B4XPlusMinus3.SetNumericRange(0, 100, 1)
    B4XPlusMinus4.Formatter.GetDefaultFormat.MaximumFractions = 2
    B4XPlusMinus4.Formatter.GetDefaultFormat.MinimumIntegers = 2
    B4XPlusMinus4.Formatter.GetDefaultFormat.MinimumFractions = 2
    B4XPlusMinus4.SetNumericRange(0, 10, 1 / 3)
End Sub

Is the expected way to copy the b4x internal lib in each of the internal libraries folder...b4a, b4j, b4i
or better to remove internal libraries and put it in additional b4x ?

Ähmm....Nope Question:
How to assign b4xPlusMinus1 directly to the....say... third city in this case?

Yes. The good news is that the latest version will be included when the IDE is updated.

Dim cities As List = File.ReadList(File.DirAssets, "cities.txt")
B4XPlusMinus1.SetStringItems(cities)
B4XPlusMinus1.SelectedValue = cities.Get(2)

 

[Roberto P.]

it would be interesting to add long press for automatic increased or decreised.

It's there already! Press and hold, in the sample from the first post

Rapid - Whether to allow rapid changes with long clicks. Note that you can change the durations used for the rapid effect (RapidPeriod1 and RapidPeriod2 fields - default values are 1000ms and 30ms).

Hi

For anyone looking: Visibility is controlled by: B4XPlusMinus1.mBase.Visible = False (or Ture)

Works really well thank you!
