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.

Thankyou. That works.

Another two

1) Is it possible to programatically disable a dialog button? For example, I want to disable the OK button until some condition is met.
2) I have a TabHost and the dialog positions itself below the tabs. How can I make the dialog position itself at the top of the screen?

Thanks again,

There is help for this library. I saw the examples but would be nice if it has a helpfile to read before.

how can I do to read a String

x=Dlg.String()

Thks!

Can you elaborate what exactly are you trying to do because all my language skills were not enough

Are you asking how you can take as input from user a String?

B4X:

Dim Id As InputDialog
   Dim ret As Int
   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")
Msgbox("You entered: " & Id.Input)

This code is from the previous page, I just fixed some logical mistakes. What can be improved is that you check ret against DialogResponse.POSITIVE so that the logic is executed when the user has clicked YES only. That should happen exactly after calling Show(). The buttons you don't need should be left as empty string in the corresponding argument.

If you don't need an icon, just pass Null to the last argument instead of Bmp.

Hi Andrew,

Not sure if you're still active on this or not but I'll post my queries anyway

1) An entry in post 52 mentioned about programatically closing a customdialog, I take it that it's still not possible to do and that the three buttons on the bottom do all that.

2) I'm having issues with making a MsgBox and ProgressDialog open while the customdialog is open. Am I correct that this is not possible owing to the way Android works? I'll just do some fudges to make it work if that's the case - would prefer not to but such is life.

3) I'm using a Jelly Bean device, Galaxy S2 with latest CM10 - nice , and find that I can click outside the customdialog and that closes the dialog. Is there a way to stop that? If not are you planning an update or should I just implement a fudge to reload the customdialog?

Those issues aside it's a fantastic set of dialogs!

Cheers,

Jon

Hi, I use dialog custom in project ... I added six EditText in the dialog but I would need more, how I can scroll the contents of the dialog?

tnx

joneden · Sep 13, 2012

That's easy enough - I use customdialog2 and you add a ScrollView to it

B4X:

uxPopupInfo.AddView(uxPopupInfoScrollView, 85%x, 250dip)

Before that add a panel to the scroll view with the EditText views on it...

Hope that helps

Correct.

You can't do this.

No.

joneden · Sep 13, 2012

Cool thanks for letting me know. I have work arounds for all issues now...

Close Keyboard

I don't know what I'm missing, but I can't get the keyboard to close at all. I have a droid X, Android 2.3.4, I open an input dialog, click on the box, keyboard pops up, I enter the text, click add, everything works, but the keyboard won't close. There has to be a way to close it. If I hit enter, the keyboard goes away, but then I still have to click Add.

Any help?

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.

That looks like a CallSub has become a CallSubDelayed in the ListView code. Only Erel can tell.

The previous post was deleted by the author, so I'm not sure what is the context of this question. ListView_ItemClick now uses BA.RaiseEventFromUI instead of BA.RaiseEvent. It should have been changed before. It is somewhat similar to CallSubDelayed, though CallSubDelayed is much more sophisticated.

Hi Erel,
I use a custom dialog (modal) with a listview. In the previous version of B4A the ListView_ItemClick-event was triggered when an item was tapped in the listview, in the version 2.20 (same project without any changes in code) the ListView_ItemClick-event only gets called when the dialog is closed. It occurs to me that you explain here the reason for this behaviour - but i don't understand what i have to change in my code... :BangHead: Could you help me?
Many thanks!
Tom

Erel · Oct 8, 2012

You will not be able to handle this event in a modal dialog. You will need to use a non-modal implementation.

joneden · Oct 17, 2012

Hi Erel,

Referencing the previous two posts, you said you would need to use a non-modal approach for the spinner (actually listbox but I'm getting the same issue with a spinner). Is there no way around this such as reflector? Seems weird to me as other click events all work on the custom dialog - I have image views reacting to clicks, checkboxes etc....

Alternatively do you happen to know if there is a custom spinner type control that might work instead?

Regards,

Jon
