[B4X] AS WheelDateTimePicker - based on ASWheelPicker

This is a date and time picker in IOS picker design. This library is based on the ASWheelPicker, without it the library will not work. https://www.b4x.com/android/forum/threads/b4x-xui-as-wheelpicker-spinner-a-modern-single-multiple-choice-picker-view-based-on-xcustomlistview-payware.127505/...

B4j: jXUI,jBitmapCreator,jReflection,xCustomListView,XUI Views
B4a: XUi,BitmapCreator,Reflection,xCustomListView,XUI Views
B4i: iXUI,iBitmapCreator,xCustomListView,XUI Views
On B4I you need the GestureRecognizer or download a version without errors down below. No longer needed V1.06+
Examples:
Add 2 Wheels with a list of maps: 
Dim tmp_lst As List : tmp_lst.Initialize 'Create and Initialize the list
    'Fill the list with dummy items
    For i = 0 To 50 -1
    'text - the text to display in the wheel
    'value - any value you want to identify the text E.g. a id
    tmp_lst.Add(CreateMap("text":"Test " & i,"value":i))
Next
ASWheelPicker1.AddWheelAdvanced(tmp_lst)'adds the list to the view and adds a wheel
Get the Selected Items: 
'gets the item of the first wheel
'use this function when you have added the wheel with AddWheelAdvanced
Dim tmp_m As Map = ASWheelPicker1.GetSelectedItemAdvanced(0)
Log("Text: " & tmp_m.Get("text"))
Log("Value: " & tmp_m.Get("value"))

'use this function when you have added the wheel with AddWheel
Log("Text: " & ASWheelPicker1.GetSelectedItem(0))

Hi @Alexander Stolte Does this spinner support a long click (on the up down arrows) event? Also changing background colors...or transparent background (I can make transparent work in my project). Thanks much!

The arrows in the picture are not included in the view. I just placed a label at the top and bottom of the designer.

Is this a question or a statement? In case of a question: Just set the "Background Color" to transparent in the designer

Hi Alexander,
I'm not able to show a border on this control.
Also, the text size looks smaller than the same text shown in a label for example. Do I have to set font at runtime (not in the designer) ?

This is normal because you have the following thing in the designer script: AutoScaleAll

Since I don't create the labels using the designer, but rather using code, the designer script has no influence on how large text is displayed.

Remove AutoScaleAll from the designer script or increase the font size:
B4X: 
Dim ItemTextProperties As ASWheelPicker_ItemTextProperties = ASWheelPicker1.ItemTextProperties
ItemTextProperties.TextFont = xui.CreateDefaultFont(20)
ASWheelPicker1.ItemTextProperties = ItemTextProperties

Ok. This is because I want the graphics looks identical both in IOS and Android. But not a big problem, I'll try with a background panel
Thanks
