B4A Library Dialogs library

This library contains several modal, that is blocking, dialogs by which the user can enter data. Presently they are an InputDialog for numbers and text, a TimeDialog for times and and a DateDialog for dates.

Note that modal dialogs can close unexpectedly and not return to your code if the Activity needs to close, most likely because the user rotated the device. There is a brief discussion of this in the overall library help in the xml. This can also occur with the Basic4android modal dialogs InputList, InputMultiList, Msgbox and Msgbox2 whose modal mechanism is used by the dialogs in this library.

How to use this to load a file?

normally I would load the text file with:
tmptxt=File.ReadString (File.DirRootExternal & "/CrN", Filename)

but this locks my to sdcard/CrN. Can I use Dialogs to load from anywhere?

tmptxt=File.ReadString (????????)


Kind regards
Jakob

You can load the string from anywhere you like.

Andrew,
Is it possible for you to add a workaround for the TimePicker/DatePicker value sticking problem. When you enter a value using the keyboard it does not stick until focus is cleared from it. If you use a timepicker.clearfocus maybe that will do the trick and bypass this annoying feature.
Thanks.

 

[agraham]

No. As I wrote in post #8.

I am afraid that I don't think there is anything I can do in the library as there is no interaction possible in code with the dialog between showing it and receving the values back when the user closes

 

[thedesolatesoul]

Andrew,
I have already tested this. Even after the user closes the dialog, if you do TimePicker.ClearFocus() it sets off some onChanged events, and returns the changed value.
After all, even though the dialog is not visible any more the reference to the views has not been destroyed yet.
Ofcourse, this is just a suggestion.

 

[agraham]

Good find! I am astonished that clearFocus() does anything at all on a view that is not displayed. I suppose it's just yet another bit of Android crapiness.

Version 2.8 now posted incorporates this in TimeDialogand DateDialog.

 

[thedesolatesoul]

Thanks Andrew.
It is true that Android does act rather weird, I guess it is not properly optimised either due to its inheritance from linux or because google wants it to be whacky. Either way developers are forced to make workarounds.

Is it possible to show keyboard and dialog altogether?
I want to display a logon feature on my app, (an InputDialog with password mode set to true) like this

Dim inputText As InputDialog
inputText.PasswordMode=True
inputText.Show("Enter password please","Log on","OK","","Exit",Null)

The only "problem" is that user must manually press into dialog field for the keyboard to be display.
Is there any chance to automate this process a little, please?

Hello agraham,

I don't know if its possible but it would be nice if the dialog titles would support RichStrings instead of Strings.
I use custom dialogs to display the results of previous searches. Using own views it is easy to highlight the results with the search expressions, but if the title is part of the result the highlighting won't work at the moment.

ColorPickerDialog via CustomDialog

hello your library is formidable !

but, in my program I want to launch a ColorPickerDialog via a button in a panel of CustomDialog , but I click the button ColorDialog does not open, if I set the panel to activity, the ColorDialog opening it's ok

it's normal ?

 

[Erel]

You cannot open a modal dialog when another one is open. Try to use a timer with a short interval that will open the color dialog after the current dialog is closed.

Is there a way to close Custom dialog?

Hi Andrew,
Is there a way to close the Custom dialog from external event?
I mean the following: I created a custom dialog with a List View embedded:

Dim bmp As Bitmap
Dim cd As CustomDialog2
Dim C1 As fgContact
Dim j As Int
ItemSelected = -1

If ( ContactsList.IsInitialized = False) Then

ProgressDialogShow("Please, wait while reading contacts")
For j = 1 To 5
DoEvents
Next
Try
ContactsList = Contacts.GetAllContacts( False, False )
ProgressDialogHide
Catch
ProgressDialogHide
End Try
End If



Dim lv As ListView
lv.Initialize("lv_Acc")
Dim i As Int

For i = 0 To ContactsList.Size - 1
C1 = ContactsList.Get( i )

lv.AddSingleLine2 ( C1.DisplayName, C1 )

Next



cd.AddView(lv, 77%x, 60%y)

bmp.Initialize(File.DirAssets, "android48.png")
ret = cd.Show("Contacts list", "OK", "Cancel", "", bmp)
If ( ret <> DialogResponse.CANCEL ) AND ( ItemSelected <> -1) Then
C1 = lv.GetItem( ItemSelected )
edtAccName.Text = C1.DisplayName
ContactID = C1.Id
End If



I add an event procedure:

Sub lv_acc_ItemLongClick (Position As Int, Value As Object)
ItemSelected = Position
ToastMessageShow("Click OK to select item", False )
End Sub


Is there a way in this procedure to close the dialog with a "OK" modal result?

As you see, I display a toast message to the user to Click OK to confirm the selection, but will be better to automate this process and click OK in the event.

[Inman]

Not sure if this will work, but I suggest 2 changes

First, you don't need to pass Null for all the arguments. Only the last one (bitmap) needs Null. For others use "" (empty double quotes).

Second, if you want the dialog to show today's date on startup, simply use Dd.DateTicks = DateTime.Now

 

[sioconcept]

Thank you Inman, but no change

The DateDialog open nice; it's only when i push a button else i can see the dialogbox with the good day.
Strange :sign0161:

I don't find another DateDialog so nice.

 

[agraham]

It's a bug! Will be fixed in 1.92 coming very soon.
http://www.b4x.com/forum/basic4android-updates-questions/17857-basic4android-v1-9

DoEvents / Msgbox crash the application on Android 4.0.3 and Android 4.0.4

The Dialogs use the Msgbox functionality.

 

[sioconcept]

It's exactly what i need. Thanks a lot of, it's work now !

I've some tips about B4A, where i can post it ?

 

[margret]

I made a post about an issue I am having with the FileDialog. Then later saw this thread and wanted to ask if you would look at the other thread and see if I have any options.
