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.

I'm afraid that it is an Android "feature" when using keyboard entry into a dialog. There is nothing that can be done about it.

compatibility issue with Honeycomb??

I have a user who is using my app running Honeycomb. There was a spinner-issue but this has been resolved with the latest version of B4A (1.6). Now he reports force-close upon selecting an item in a dialog.

My app running on the user's other device running Android 2.2 does not present this problem.

I am still awaiting some more information from this user so I may understand the nature of the problem but I thought I would just ask in the meantime if anyone is aware about compatibiliy-issues with Dialogs running Honeycomb (Samsung Tablet 10.1 - the new one)?

Erel · Jul 18, 2011

I can test your application on a samsung 10.1. If you like upload it or send it to me.

agraham · Jul 18, 2011

I see no problems in the Dialogs demo with stock Android 3.2 on a Motorola Xoom.

boten · Jul 18, 2011

I just tried the DialogsDemo that comes with the Dialog library. On the emulator the DateDialog displayed Jul 18 2011 and the TimeDialog displayed 10 29 AM (hours value 1-12)
When I run it on the real device (Samsung Galaxy S) it showed the date as 18 Jul 2011 (as per the dateformat on the device's settings) but the time was still showing AM(PM) although my device is set to show 24 hours format.
I realise there is a "Is24Hours" attribute and when set to True shows the TimeDialog in 24 hrs format.
My question is how do I determine, programatically, which time format the phone is set to?

@Erel: thanks but it would be difficult for you to run it (especially the suspected routine) since the app requires a particular satellite-decoder in your network.

@agraham: your information is good to know since you tried it on a Honeycomb-device

I believe the problem is due to a network-routine (and thus a problem in the user's LAN) which is triggered upon selecting an item in the Dialog rather than a Dialog-problem. That's why I hope to get a more detailed report from the user but I thought I would ask anyway if any problems were known (like the spinner-view).

In addition, I have not received any other bug-reports for this issue despite my app has more than 12000 active installs of which 361 installed on honeycomb-devices. Therefore, I hope the issue is depending on something else.

You could ask your user to install CatLog from the market and to send you a saved system log when the error occurs. That way you might get a stack trace of what's happening.

moster67 · Jul 18, 2011

Good idea! Could also be useful in case of future problems. Thanks.

With my Reflection library.

B4X:

   Dim Obj1 As Reflector
   Dim args(1) As Object
   Dim types(1) As String   
   args(0) = Obj1.GetContext
   types(0) = "android.content.Context"
   Obj1.Target = Obj1.RunStaticMethod("android.text.format.DateFormat", "is24HourFormat", args, types)
   Msgbox(Obj1.Target,"is24HourFormat")

thx. worked like charm. Might be useful to incorporate into b4a?

Hello Andrew,

Thank you for this fantastic library, appreciate your efforts to help us.

Just noticed an issue with the DateDialog which I wanted to confirm:

When I enter the date manually with the keyboard the Month and Day value are returned correctly but the Year value returns only the initialized value or the last value selected using the "+" "-" buttons.

I know you have mentioned earlier in the thread regarding the Time Dialog that this is OS related, just curious why the other field are updating and only the Year does not.

agraham · Jul 20, 2011

It's not unique to the year, it's the last field changed by the keyboard that doesn't get updated.

Omar · Jul 20, 2011

Thanks for the clarification Andrew.

Agraham,
Very nice dialog library. Congrats.:sign0060:

1) Is there a way for FileDialog's FileFilter to show only files ending in .BMP or .JPG or .PNG? I can only get it to recognize one file extension. I thought I should be able to use ".BMP;.JPG;.PNG" with a ";" delimiting the extensions, but no such luck.

2) It would be nice if the FileDialog had another property FileMustExist that would be set to True to prevent the user from entering a file name that doesn't exist. I have written a sub to do this, but I thought it would be neat if it was self contained in the dialog.

Not at the moment, as the help says "If a filename contains the text of the filter the file will be displayed". I might revisit this sometime soon as it would be a nice addition.

prevent the user from entering a file name that doesn't exist.

I'll think about if I do any changes in future.

Hi Agraham!

Is it possible to set the title in a TimeDialog when the user changes the time?

When you set a new alarm in the alarm clock you know what I mean (alarm_clock.png)

One more wish:
Is it possible to remove the unnecessary space in the dialogs when no message ist set (timedialog.png)?

B4X:

ret = Td.Show("", "Zeit", "", "Zurück", "Fertig", Bmp)

Thanks!!

agraham · Aug 16, 2011

Neither is possible.

A way to add HTML link into CustomDialog2

Hello.
Can someone advise if there is a simple way to add a HTML link to a dialog box.
The only way I know is adding a label with the right color and underline to make it look like link and then in its click event use intent.

Is there a simpler way to add a link.

Thanks

moster67 · Aug 17, 2011

I am not sure if it works in the dialog-library but you can try the "linkify"-object using Agraham's reflection-library. I believe Agraham was so kind to even include a demo how to use "linkify".

Are customdialogs based on the dialogs from the Android SDK here:Creating Dialogs | Android Developers

I ask, because I want to port some dialogs (for eg progress dialog) but I remember reading somewhere that modality is not supported in Java, and B4A implements its own kind of modality for msgbox etc.
