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.

Hello,

I am using the following code and when I enter text into my Dialog and press Yes the keypad says open and doesn't close.

Is there a way to close the keypad when you click the button?

B4X:

Dim Id As InputDialog
   Dim ret As String 
   Bmp.Initialize(File.DirAssets, "icon.png")
   Id.InputType = Id.INPUT_TYPE_TEXT
   Id.Input = ""
   Id.Hint = "This is my hint"
   Id.HintColor = Colors.DarkGray 
   
   ret =  Id.Show("Please enter something", "This is my title", "Yes", "Cancel", "",Bmp)
   Msgbox(ret,"Selection")

I haved tried using IME.HideKeyboard but it didn't close.

Any other ways to close it?

Penko · Jul 28, 2012

Why would you need to close it in a dialog? I asked about the opposite(how to show the keyboard when I show the dialog) but someone said that is pretty hard. If there id no obvious method to hide it, probably it is hard too. However, why do you need it as the user inputs something' they press the button and the dialog is being hidden?

what is happening is this..

- Dialog opens
- tap on the textbox and keypad displays
- enter your data into the dialog
- press the 'yes' button in the dialog and dialog goes away
- keypad still displays and won't go away.

Everything seems to work but the keypad won't go when the dialog is not shown.

Penko · Jul 28, 2012

That's pretty strange. My keyboard hides perfectly after I click any of the buttons. It is the way dialogs work. What InputType do you use? Also, it may be a problem on your specific device. Is this yournfull code?

P.s I can't test now but it seems you have some errors. Check, but I think you have to check .Input after .Show() in order to understand what has the user typed. Also, it is good to know what button has been clicked. Test against the enum values in DialogResponse.Type.

The clicked button should be in .Response after .Show

Hello,

got it to work.

Just need to replace my messagebox with:

B4X:

Msgbox(Id.Input  ,"Selection")

and now the keypad goes away after they press the button.

Hi Everybody,
i'm just a beginner and sorry for my english.
There's the possibility to use TimerDialog to set Hour Minutes and Second?
I need it for a Count Down timer ad sometime it's possibile that the user need to set also second.

Thansk a lot for your kindly response.

Penko · Aug 6, 2012

You can easily write a class to expand with this functionality. All you need to do is define a CustomDialog inside and add the views for hours and seconds.

There's some example or documentation about that?
I'm just a beginner and I haven't any idea to perform that.

Thanks a lot for your patience.

I wrote something which is not complete. I called it DurationDialog. I will provide the code but you have to finish it yourself. That will happen a little bit later when I get back on my PC. I will edit this post with the code.

Sent from my HTC Desire using Tapatalk

Edit: Here you have the code.

Please note the following:
1) the code is not finished
2) not optimized
3) there is no "seconds" capability. You have to implement it yourself. It's not too hard.
4) there are some bugs if the user presses a button other than the Positive one.
5) setDuration doesn't set the duration at all. The fields do not take the appropriate value.
6) I am giving this code out as a hint and guide on what you have to do. There might be a better solution .
7) the fields aren't arranged for production but for testing only. You have to fine tune the positions of both the Labels, and the EditTexts.

it can be show with 3 different method
Show it's equal of original one
ShowSet: it's possible view the DialogBox and send Hours, Minute and Second at the same
ShowSetSec: it's possible view the DialogBox and send the total second.

It's possible to Set and Get all in Seconds or Fulltime in HH:mm:ss format.

I Have had + and - button for Hours, Minutes and Second.

For a better order I used Region.

Grazie mille ancora.

I didn't expect events can be caught inside the class but looks good anyway.

Ennesima77 · Aug 9, 2012

It's also possible more than one inside a region

#region "Primary"
#Region "Secondary"

#End Region

#Region "Secondary"

#End Region

#end region

it's soo useful with a very long code, I'm onest I try it in Visual Basic style without read nothing about that in the manual and it works.
(Sa' mai che ho detto ua cacchiata ti traduco quello che volevo dire:
E' davvero comodo con codici lunghi, ho provato a scrivere #Region come facevo in visual basic .net e ho visto che funziona bene allora per abitudine continua ad usarlo )

Penko · Aug 10, 2012

Hey, ho parlato per i eventi Click. No lo so che e' possibile quelli nel un Class usare.

Hey,i was talking for the Click events. I didnt now you can use them inside a class.

But the Regions really rock, anyway.

How likely would it be to get the Time Dialog to use the Date portion of the Ticks passed to it and return that with the time set instead of the weird Dec 31st 0002 date? I had a weird issue in a Bug thread Erel may have mentioned to you earlier too where apparently there is some sort of disconnect between Get and Set ticks where one uses the default DateTime object and the other uses their own. Having it use the whole ticks passed and just modify the date would fix both issues I think and make it more functional in handling tick values to be used elsewhere without the DateTime object shifting the ticks from it wrong.

Anyone had success in adding a ScrollView to a CustomDialog2?

I wanted to create a dialog with scrollable contents and this doesn't seem to be possible. If it is possible and I can't figure out how to do it a simple example would be great.

If it is not possible I think I will have to use a seperate activity instead of the dialog.

Thanks,
Markus

I'd love to know that too...

I think this has been asked but not answered.
(How) is it possible to close/hide a listview when the user clicks on an item. There's nothing like cd.hide or lv.hide or anything similar.
I'm trying to offer a selection from a list but want to avoid buttons.
