B4A Library Nice Spinner

It wraps this Github project. It requires android-support-v4.jar (a recent version) to be in your additional library folder. You can download it from here. Posting the B4A project, the B4A library files, and the Java code. If you want to make changes to the Java code and recompile it you must add android-support-v4.jar to the libs folder (libs folder is on the folder level as the src folder - see folder structure once you have extracted the zipped file).

The spinner has a nice animated arrow when the spinner opens/closes. You can set amongst others the following:

1. The background color of the selected text
2. The text color of the selected text
3. The background color of the dropdown list
4. The text color of the text in the dropdown list
5. The divider height (between entries) in the dropdown list
6. The color of the divider between entries in the dropdown list (specify 3 different colors or 3 colors of the same color)

Upon selection an event is raised in the B4A project where you can the extract the index of the selected item (first item in a list = index(0)).

Very nice Library, very useful.
Just one question.
I did not find any difference using "disabled True or False".
My application needs to block the ComboBox under some circumstances avoiding to change the first item selected.
I used disbled = False and did not work as I needed.
Any help would be welcome.

Thanks in advance.
JRuiz
Try with the attached library files (V2.01)

B4X:
ns1.SpinnerEnabled = False            'or ns1.SpinnerEnabled = True

Johan,

I have one more question.
I have several fields to populate and I am using the IME Keyboard.
When I tap the spinner, it displays the menu behind the keyboard and I have to hide the keyboard manually.
Is it possible to hide it automatically when I tap the Label of the ns?. May be something like "ns_item_clicked", but before selecting the item.

Thanks in advance
JRuiz

Try the attached library files (V2.02) and then add this to your B4A code:
B4X:
Sub ns1_spinner_touched
  
    Log("ns1 Spinner Touched")
  
End Sub

See if will help you to sort out the problem. The event will be raised as soon as what you touch the spinner but before the drop-down occurs.

I'm trying this spinner because it has a public Typeface property, and I want to use it to pick icons using the new Material Icons and FontAwesome fonts.

While the iconified text appears properly in the closed dropdown, the list in the open dropdown does not render (showing just the placeholder symbol).

It seems that the list items are not respecting the Typeface property. Any chance of fixing this?

Thanks!

Dave, I will revisit it sometime during this week - has been more than a year since I have wrapped it.

Dave, try the attached B4A project and new library files (note the invisible label added in the designer):

B4X:
    Dim r1 As List
    r1.Initialize
    r1.AddAll(Array As String("One" & Chr(9) & Chr(9) & Chr(0xF179), "Two"  & Chr(9) & Chr(9) & Chr(0xF17B), "Three" &  Chr(9) & Chr(9) & Chr(0xF17A), "Four" & Chr(9) & Chr(9) & Chr(0xF061), "Five"  & Chr(9) & Chr(9) & Chr(0xF179)))
    Dim divcolor() As Int = Array As Int(Colors.Blue, Colors.Green, Colors.Red)
    ns1.DividerColor = divcolor
    ns1.DividerHeight = 1
    ns1.DropdownListBackgroundColor = Colors.Green
    ns1.attachDataSource(r1)
   
    'do this after ns1.attachDataSource(r1)
    ns1.DropdownListTypeface = l1.Typeface
    ns1.Typeface = l1.typeface
   
    ns1.DropdownListTextColor = Colors.Magenta
    'the next two lines of code must be before ns1.SelectedIndex is set
    ns1.SelectedTextColor = Colors.Blue
    ns1.SelectedTextBackgroundColor = Colors.White   
    'always set this even if just to 0
    ns1.SelectedIndex = 0
    ns1.SpinnerEnabled = True

Hi Johan, thanks for posting this update so quickly.

I can confirm that when using code to set the properties, the typefaces now work correctly. Thanks.

However, if I add the spinner using the Designer, some of the new properties are not available.

Also (and more importantly), if I set properties like Typeface and Size in the Designer, these are ignored when the app is run. Is that something you can reproduce, or perhaps a problem at my end?

Thanks again!

Hi Johan,

How can we clear the items in the dropdown?
Without having to change the library you can perhaps do it with the following code:
B4X:
#Region  Project Attributes
    #ApplicationLabel: NiceSpinner
    #VersionCode: 1
    #VersionName:
    'SupportedOrientations possible values: unspecified, landscape or portrait.
    #SupportedOrientations: landscape
    #CanInstallToExternalStorage: False

#End Region

#Region  Activity Attributes
    #FullScreen: False
    #IncludeTitle: True
#End Region

    'These global variables will be declared once when the application starts.
    'These variables can be accessed from all modules.

    'These variables can only be accessed from this module.

Try it and see if it works for you

Hi Johan,

Thanks for the reply. I found out that if I manipulate the list attached to the control datasource(attachDataSource) and re-attach it to the control, the list items are changed.

So thanks. No need to remove the view.

Hi Johan,
is there a way to change the textsize of the dropdownlist items?
See the attached B4A project and new library files (V2.03)

Use it as follows:
B4X:
ns2.DropdownListTextSize = 10
ns2.SelectedItemTextSize = 15

** Activity (frmitem_maintenance) Resume **
See post #18. You are missing the files in the B4A project's /Objects/res/bla bla folders. These files need to set to READ ONLY else they will be deleted the first time that you compile the B4A app.
