Hi, Can you share a more complete example please? I want to to integrate the picker on my app. From the example source code is not easy...
Sorry i'm not very experienced. My application does not use b4xmainpage and compiles well. I just want to to add a number picker.
Thanks

I just want to to add a number picker.
B4X:
Dim tmp_lst As List : tmp_lst.Initialize 'Create and Initialize the list
For i = 0 To 50 -1
    tmp_lst.Add(i)
Next
ASWheelPicker1.AddWheel(tmp_lst)'adds the list to the view and adds a wheel

Hi,
It is working. But I have now another problem. I want to add 4 different pickers with 4 numbers each. I have created the pickers also in the designer (exact copy) and every one of them work fine except for the font size and separator... font is ok on picker 1 and 3 and separator is ok on picker 2 and 4..
What i'm doing wrong?

Thanks and sorry for all the questions.

What i'm doing wrong?
B4X:
    ASWheelPicker1.ItemTextProperties.TextFont = xui.CreateDefaultBoldFont(50) 'makes the items bold
    ASWheelPicker2.SeperatorProperties.TextFont = xui.CreateDefaultBoldFont(50) 'makes the seperator text bold
    ASWheelPicker3.ItemTextProperties.TextFont = xui.CreateDefaultBoldFont(50) 'makes the items bold
    ASWheelPicker4.SeperatorProperties.TextFont = xui.CreateDefaultBoldFont(50) 'makes the seperator text bold
Because you are changing only for Picker 1 and 3 the ItemTextProperties for the other 2 you are only changing the SeperatorProperties.

Hi All,
It's me again....
Code is almost done and working ok. I'm in the final tests in several different devices.
It works ok in Android 10 devices, but in one device with android 8.1 it fails.



The program crashes at line 178


it only happens with the device using android 8.1

Thanks

Update
  • 2.03
    • Add Event BaseResize - Triggers as soon as the width in the view has changed
    • Add Event ItemChange - Triggers when an item reaches the center while scrolling, so you can display the results e.g. in a label instant
    • B4I Item snap is now smooth
ItemChange
with this event you can do something like this:

B4I Item snap is now smooth
In B4A it already feels smooth enough, but in B4I it feels much better now.
BaseResize
will only become relevant in the next update. In the next update you can adjust the width of the wheels themselves, so it is possible to display more text with more width if you need it.

Update
There is a backup of version 2.03 in the 1st post in case of problems

  • 2.04 (read more)
    • Complete rework of the wheel sizing
    • Add Designer Property WidthMode - Default: Automatic
      • Automatic - You don't have to worry about anything, the view calculates the right size for all wheels
      • Manual - Set the wheel sizes you need via "SetWheelWidth"
    • Add WheelWidth to ItemTextProperties - This allows you to set the width of a wheel manually, only working if WidthMode = Manual - Default: 0
    • Add SetWheelWidth - Sets the width of an wheel, only working if WidthMode = Manual
    • Add get and set Events - Enables or disables the events
    • Haptic feedback disabled if you call Scroll2Index
    • BugFixes
WidthMode = Manual
You can now determine and divide the width of the wheels yourself.
For example, the 1st wheel has a width of 70% of the total width of the view, the 2nd wheel has the remaining 30%.

B4X:
Private Sub B4XPage_Resize (Width As Int, Height As Int)
    If ASWheelPicker1.NumberOfLists = 2 Then 'To ensure that the code is not executed until the 2 wheels have been added
        ASWheelPicker1.SetWheelWidth(0,(Width*70)/100)'70% of total width
        ASWheelPicker1.SetWheelWidth(1,(Width*30)/100)'30% of total width
    End If
End Sub
Is compatible too with Separators

*Red = Separators
*Blue = Items

I have your excellent ASwheelpicker library and wondered if you were aware of any issues with Android 12.
Unfortunately I don't have an Android 12 device yet, before I go out and purchase one for debugging I just wanted to check.

I have a customer whose app is crashing when he opens a page with wheelpickers on (it's working fine in Android 11), everything else in the app is working.

Thank you
Lisa

B4X:
TyreWheelPicker1.Curved = True
    TyreWheelPicker1.Cyclic = True
    TyreWheelPicker1.CurtainColor = Colors.ARGB(50, 100, 100, 100)
    TyreWheelPicker1.Curtain = True
    TyreWheelPicker1.ItemTextColor = Colors.Black
    TyreWheelPicker1.Atmospheric = True
    TyreWheelPicker1.ItemAlign = 0                     
    TyreWheelPicker1.ItemTextSize = 80
    TyreWheelPicker1.SelectedItemPosition = 0            
    TyreWheelPicker1.SelectedItemTextColor = Colors.Black
    TyreWheelPicker1.VisibleItemCount = 3
    TyreWheelPicker1.SameWidth = True
    tyrelist.Initialize
    tyrelist.AddAll(Array As String("ALL",0,1,2,3,4,5,6,7,8,9,10))
    TyreWheelPicker1.Data = tyrelist
