Android Question Prefdialog set default time

[andyr00d]

Hello,

I'm struggling to set a default time for a prefdialog time field, I understand that it must be of type period however I've tried the below simple implementation and it's not crashing, but it's also not setting the time (it's showing 12 00 AM by default in the field).

    Dim time As Period
    time.Initialize
    time.Hours = 11
    time.Minutes = 2
   
    Dim ls As List
    ls.Initialize
    ls.Add(time)
    prefdialog.SetOptions("4", ls)

The output of time is: [Days=0, Hours=11, IsInitialized=true, Minutes=2, Months=0, Seconds=0, Years=0]

I thought this would set it to be "11 02 AM" but it's not working, any ideas?

There is a conceptual mistake here.

Default values are set in the Data map. The map that is passed to PrefDialog.Show.

But that map is created via LoadFromJson, and I don't think the value can be set within the json file can it?

No. No.

The json file creates the template.
The data map stores the initial values and the set values.

No, with LoadFromJson you create the "form" layout.

Review again the B4XPreferencesDialog, when it says:
2. Call ShowDialog and pass the data map. It can be an empty map or a map where some of the fields are already set.
B4X:

'Options1 is a Map object
Wait For (prefdialog.ShowDialog(Options1, "OK", "CANCEL")) Complete (Result As Int)
If Result = xui.DialogResponse_Positive Then
PrintOptions(Options1, TextArea1)
End If

The data map will be updated when the user clicks on the OK button.

So Options1 is the map where you get the answer, but if it's populated with data, it will be shown as filled in the dialog. That's where you have to set you default time.
