B4J Library [B4X] [XUI] AnotherDatePicker

Edit: don't use this library. Use B4XDialog + B4XDateTemplate from XUI Views library instead.

This is a cross platform version of AnotherDatePicker custom view based on XUI library.

Designer properties:

The user can enter the date directly into the field. The field border color will change to red when the value is invalid.

Notes:

- B4J buttons raise the Action event. This is handled in the code with:

#if B4J
Private Sub btnCancel_Action
#Else
Private Sub btnCancel_Click
#End If
   Hide
End Sub

Click event will be added in the next version of B4J.

- It depends on XUI v1.3+.
- If you are using a B4i version before 4.4 (stable) then you need to remove the reference to iDateUtils library and add the DateUtils code module instead. This is related to a bug fixed in B4i v4.4.
- You might see a warning while debugging about a missing RaiseSynchronousEvent attribute. You can ignore it. It is related to changing the text programmatically while handling the TextChanged event.
- This is quite a complicated custom view and it is a good example of using XUI library to write cross platform code.

Versions

1.03 - Fixes an issue with CloseAllDialogs always returning True (https://www.b4x.com/android/forum/threads/b4x-xui-anotherdatepicker.85160/page-2#post-581920).
1.02 - Fixes an issue with dates before 1970.
1.01 - Sets the elevation of the dialog panel.

Latest version is attached separately.

Are there any specific OS requirements for this class/XUI library to run?

Tested with B4A 7.0 on GenyMotion emulator, compiled OK, no error, but when run on Android 4.2.2, forced closed.

 

[Erel]

Can you post the error logs?

 

[incendio]

That's the problem.

No Error log on B4A, compiled OK, but on the device (Genymotion), error message raised :
"Unfortunelly B4A Example has stopped."

Tested on Android 4.2.2 and 5.0.

 

[Erel]

There must be an error message in the logs. Run the app in debug mode if you are using B4A-Bridge.

 

[Erel]

I've tested it on a real device running Android 4.1. It ran properly.

[Erel]

I'm unable to reproduce it. Please try it with this code in the class:

Private Sub DateField_TextChanged (Old As String, New As String)
   Dim ticks As Long = GetCurrentDateFromTextField (New)
   If ticks > 0 Then
       setDate(ticks)
       If dateField.IsInitialized = True Then dateField.SetColorAndBorder(dateField.Color, 2dip, 0xFFA1A1A1, 0)
       CallSub2(CallBack, EventName & "_DateChanged", ticks)
   Else
       If dateField.IsInitialized = True Then dateField.SetColorAndBorder(dateField.Color, 2dip, xui.Color_Red, 0)
   End If
End Sub

   End If
End Sub

It works OK now.
The problem was in the "else" part of the If clause.
Thank you a lot @Erel

 

[LucaMs]

I would add:

#DesignerProperty: Key: Enabled, DisplayName: Enabled, FieldType: Boolean, DefaultValue: True


Public Sub setEnabled(Enabled As Boolean)
   btnOpen.Enabled = Enabled
   dateField.Enabled = Enabled
End Sub
