B4A Library Dialogs library

agraham · Dec 7, 2010

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.

The demo enclosed in the archive includes getting a value from the NumberDialog and showing it in a tost. If you want the value in a varible

myvar = nd.Number

Thank you very much indeed. Charles

CharlesR · Apr 4, 2011

Thank you for your earlier help. I am getting on well with your excellent dialogs but have one question which is probably very simple. I am using this code to get an opening time, but would like to pad it so it displays hour and minutes both as 2 digits eg in the format 06:00 please could you show me how to do that. Sorry for another newbie question.

Sub openTime_Click
Dim td As TimeDialog
Td.Hour = 06
Td.Minute = 00
Td.Is24Hours = True
ret = Td.Show("Set the opening time", "Opening Time", "Yes", "No", " ", Bmp)
openingTime = Td.Hour & ":" & Td.Minute
openTime.Text = openingTime
ToastMessageShow(ret & " : " & Td.Hour & ":" & Td.Minute, False)
End Sub

Hello Charles,

Please try this:

DateTime.TimeFormat="HH:mm"
openTime.Text = DateTime.Time(td.TimeTicks)

Cheers
Robert

CharlesR · Apr 4, 2011

That's great. Thanks Robert.

Charles

CharlesR · Apr 5, 2011

I am obviously missing something very simple, but in the previous time dialog, the returned time displays in the button, but in this number version it does not. Can anyone explain what I am doing wrong please?

Sub getfloorArea_Click
Dim nd As NumberDialog
nd.Digits = 5
nd.Number = 6000
nd.Decimal = 0
nd.ShowSign = False
ret = nd.Show("Floor Area", "Yes", "No", " ", Bmp)
floorArea = nd.Number
End Sub

Thanks Charles

Sorry everyone - very silly question caused by looking too hard!!

It seems a shame to post a new version and see the download count drop from 376 to 0 This must be the most downloaded library I have written.

I can't believe that it didn't occur to me to do this until now. Adding a view to the original Custom dialog required specifying its absolute position within the dialog as well as its size. This made centering the view in the dialog a bit hit and miss on different screen sizes.

I have now added a Custom2 dialog that requires only the view size specifying, the added View will be automatically centred in the dialog.

By the way, Android 3.0 Honeycomb appears to automatically wrap a dialog to the size of the added view, ignoring the top and left parameters so Custom and Custom2 dialogs appear identical on my Motorola Xoom. EDIT :- This is not in fact correct. I was being mislead by having an overrlarge Panel that I was adding to a Custom dialog!

new version

I love this library, it is a tool I will use alot. I just downloaded ver 2.1 when I unzipped it there is no .jar or .xml. There was a demo which throws an error

B4X:

Error parsing program.
Error description: Unknown type: customdialog2
Are you missing a library reference?
Occurred on line: 124
Dim cd As CustomDialog2

my current library is 2.0...did I miss something? ...again thanks for all your great work.

No, I'm afraid that I did.:sign0161: More haste less speed needed methinks!

Now posted properly

tremara1 · Apr 26, 2011

Done..

Thanks........

Cor · Apr 26, 2011

using 2.1

when clicking for the second time the custom dialog button you will get at remove view error

agraham · Apr 27, 2011

Do you mean in the demo? Which button, Custom or Custom2? They both work fine for me. What is the wording of the error and how is it presented? Have you looked in the filtered and unfiltered Logs for a stack trace?

Cor · Apr 27, 2011

It goes wrong when i wanted to add a label to the pnl

and i wanted to update this label outside the custum click routine

I have now updated my routine and it is working ok, without label

agraham · May 6, 2011

Version 2.2 now posted fixes the error in the Month parameter of SetDate in DateDialog.SetDate which gave one month later than the one requested.

NumberDialog now uses the native colour scheme for the + and - buttons and for the numerals.

FileDialog FileFilter

I want to limit the files in a filedialog to a specific file extension but show all files of that type regardless of case. I think I read somewhere that the filter (or android) is case sensitive.

Does the FileDialog FileFilter allow multi file types as it does in Basic4PPC or only a single file type?
Does it support wildcards?

Thanks
Colin

agraham · May 7, 2011

Like the help says

If a filename contains the text of the filter the file will be displayed.
A value of an empty string, the default, will show all files.

Hi agraham,

can you add this control in your library?

NumberPicker Widget for Android | Quietly Coding

Most importantly, these two properties:
mStart = DEFAULT_MIN;
mEnd = DEFAULT_MAX;

Thank you,
Filippo

aklisiewicz · May 31, 2011

I have copied the files to the
C:\Program Files\Anywhere Software\Basic4android\Libraries\Dialogs2.2
but I cannot see the library on the reference list list.

Am I missing something ?

Arthur

klaus · Jun 1, 2011

You must unzip the the zip file.
Copy Dialogs.jar and Dialogs.xml to
C:\Program Files\Anywhere Software\Basic4android\Libraries

If you have installed a folder for the addidtinal libraries you could copy these two files to this folder rather than to the folder above.

Best regards.
