Hello,
this is a modern wheel picker, like the IOS-PickerView.
WheelPicker/Spinner

This library is not free, because, it cost a lot of time and gray hair to create such views.

[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))

Testing....
I use another of your libraries. Currently if I add ASWheelPicker, then GestureRecognizer (which I think is use by another of your libraries, states as an unkown type. If I remove gesture, then no warnings regarding ASWheel but with the other libs thorughs another exceptions.

1671576743087.png


For example, I get this log:
GestureRecognizer - 149: Unknown type: swipe_attributes<br />Are you missing a library reference?

Hi
I have a problem using WSWheelPicker for B4i - The same code works great for B4a

For B4i (only) it appears the NextItem() method increments the wheel by 2 and the PreviousItem() method moves the wheel down but not enough to decrement it by one (so it remains unchanged).

Code extract.: 
' Increase hours
Private Sub lblUpWheel_0_Click
    ASWheelPicker1.NextItem(0, True) ' Increments the wheel by 2
End Sub

' Decrease hours
Private Sub lblDownWheel_0_Click
    ASWheelPicker1.PreviousItem(0, True) ' Moves the wheel down, but not enough to decrement the value
End Sub

Prehaps it just me (or something I must doing wrong for the B4i code) but it works great under B4A.

Note: Tried updating to latest version of WSWheelPicker (v3.11) but still has the same problem (previous version was v3.02).

Kind regards
Dave Morris

It should now work.
The update is released earlier than I had intended, it can be the behavior occur which are not desired, because I had to change a few things internally because of another bug.

Hi
It works now using v3.12 and changing SelectRow() to SelectRow2() - thanks for the help.

Can I make some comments
1. I believe the a description of the SelectRow2() should be added to your class documentation.
2. Its interesting to note that SelectRow() works for B4A but not B4i (You must use SelectRow2()) - In my case the wheel index number corresponds to the value on the wheel so could this suggest a problem with SelectRow() for B4i?

Kind regards
Dave

Works also in B4I, this function is used internally to scroll. Remember that the index starts at 0

Hi

Perhaps I should have explained the problem in greater detail.

My test code - set the wheels to display 0:1:2: 
' This code shows 0:1:2 on the wheels
    ASWheelPicker1.SelectRow2(0, 0, False)
    ASWheelPicker1.SelectRow2(1, 1, False)
    ASWheelPicker1.SelectRow2(2, 2, False)
    
' This code shows 0:0:0 on the wheels
    ASWheelPicker1.SelectRow(0, 0, False)
    ASWheelPicker1.SelectRow(1, 1, False)
    ASWheelPicker1.SelectRow(2, 2, False)

I do start the index at 0 (and display 0) i.e. so I can adjust times like 1:0:58

Further I used SelectRow() in my App with previous versions of AsWheelPicker and they showed the times correctly, For the latest version 3.12, I had to change SelectRow() to SelectRow2() to make it work.

I do see the usefulness of SelectRow2(). As I see it, SelectRow2() allows the wheels to display Mon, Tues etc without having to worry what index number corresponds to which day of the week (please advise if I have got it wrong!)

Kind regards
Dave

it is possible to hide a Wheelpicker?
Click to expand...
I think you mean if you can remove a wheel instead of hiding the whole view.

You can remove wheels, but you can't just hide them.
B4X: 
ASWheelPicker1.RemoveColumn(0)
ASWheelPicker1.Refresh
