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.

Works fine for me!

B4X:

   ...   
   Dim lv As ListView
   lv.Initialize("lv")
   lv.AddSingleLine("one")
   lv.AddSingleLine("two")
   lv.AddSingleLine("three")
   pnl.AddView(lv, 300dip, 120dip, 120dip, 250dip)
   
   cd.AddView(pnl, 77%x, 60%y) ' sizing relative to the screen size is probably best
   ret = cd.Show("B4A Custom Dialog", "Yes", "No", "Maybe", Bmp)      
End Sub

Sub lv_ItemClick (Position As Int, Value As Object)
   ToastMessageShow(Position, True)
End Sub

That is strange. My code is similar, except I used AddTwoLinesAndBitmap2. Must be some mistake of mine.

I will probably switch to Tabhost. Thanks for the help anyway.

Thanks

Hi agraham.
Thanks for the useful insight. Yeah.. since it's a "feature", I guess there's nothing that can be done.

Once again.. thanks for the great work in producing the libraries!

Trouble setting ColorPicker palette

Hello,
I am probably messing up the Basic language syntax but i am not able to solve this problem.:BangHead:
I am trying to set the palette to a predefined colors. Here in my code they are bogus. I created an array of integers and there are 15 as required in the documentation. Then I copy / reference the array to the ColorPickerDialog.palette parameter.
The code compiles but at run time I get an error ".....java.lang.ArrayIndexOutOfBoundsException...."
What am I doing wrong?

Thanks.

B4X:

Dim result As Int
Dim CPD As ColorPickerDialog
Dim ColorZ() As Int
ColorZ = Array As Int(0xff0000,0x00ff00,0x0000ff,0xeeeeff,0x020202,0x777777,0x777777,0x777777,0x777777,0x777777,0x777777,0x777777,0x777777,0x777777,0x777777)
CPD.Palette = ColorZ
CPD.RGB = Main.ChrColor
result = CPD.Show("Pick Character Color","OK","Cancel","",Null)

agraham · Sep 8, 2011

Sorry, it's a typo. If you count there are sixteen colours in the dialog so the array needs to have 16 entries.

brainfart · Sep 8, 2011

I counted 15
3 rows of 5 plus the current color but that one comes from the RGB parameter.
I even added a

B4X:

ToastMessageShow("Array Size: " & CPD.Palette.Length,True)

to see what it is by default and it returned 15.
I have verified that I am using dialogs version 2.6
So since the size of palette array is 15 and mine is 15 why do I get the error.
Is there a problem in my syntax CPD.Palette = ColorZ ?

agraham · Sep 8, 2011

This time I actually took the time to look at the code instead of answering off the top of my head - usually a bad idea!

It's a bug in a range check in the code, I'll post a new version soon to fix it.

agraham · Sep 9, 2011

Version 2.7 now posted fixes the problem with assigning to CololorPickerDialog.Palette .

brainfart · Sep 13, 2011

Thank you.

Hello Andrew,
I am seeing a small issue with the Time dialog (probably affects date dialog as well).
When you enter the time with the virtual keyboard, and click done, the time doesnt return correctly. Only if you use the +/- buttons or the edit text (for minutes/hours) loses focus, only then the correct time is returned.

agraham · Sep 17, 2011

It's a known feature of the Android dialogs.

Hide soft keyborad

Hallo Graham,

hopefully I didn´t miss a previous entry. I´m using your component and it´s very usefull. But the user has always to click twice on the ok-Button with this code:

Dim GetPW As InputDialog
GetPW.PasswordMode = True
GetPW.Input = ""
GetPW.Hint = "Bitte Passwort eingeben"
ret = GetPW.Show("Passwort","Passwort eingeben", "OK","","",Null)

(one on the ok-Button of the dialog, the second click to close the soft keybord.
Is there a way to hide the soft keyboard with the click on the dialog´s OK-button?

Kind regards, Oskar

agraham · Nov 14, 2011

As from version 2.4 of the Dialogs library pressing any of the three Dialog buttons in the InputDialog and the two CustomDialogs with the keyboard displayed should close both the dialog and the keyboard. It does this on both my ZTE Blade (2.1) and my Motorola Xoom (3.2). If it does not do it on your device then it must be a "feature" of that device.

Dialogs v2.7
Keyboard won't close automatically.
My phone is a ZTE Blade (CM7 - Android 2.3.7)

Hallo Graham,
thanks for your quick reply and my late one. I´m using the Galaxy Tab 7 (P1000) with V2.2. I checked the behaviour: on my device the keyboard is closed when the dialog appears. When clicking on the input text, the keyboard is shown. Any idea?

Kind regards, Oskar

"It seems to be a "feature" of the actual Android DateDialog that if you enter a number by the keyboard it doesn't "stick" until you press + or - or move the focus to another date element. 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 it."

Andrew, is there a way for the TimeDialog to not allow the keyboard to pop up, so this problem can't surface, thanks

Trapping the Enter key in the input dialog

Hi Agraham,

Thanks loads for the useful Dialogs library. Not being a real UI expert this saves me a lot of time developing my apps.

I am using an input dialog to let users perform searches from within my app. The dialog itself works perfectly except for something one of my users has asked for, and that is for the Enter key on either a physical keyboard or D-pad to be synonymous with clicking OK. Is this possible to do with the Dialogs library?

Thanks,
Steve

Hi,

is there an elegant method to let the user input an ip address?

When I set the InputDialog.INPUT_TYPE_DECIMAL_NUMBERS one can only enter a single dot, but also a minus sign.

Sure, I'll check the user input with regex, but it would be nice if the user can't even enter "wrong" characters.

Erel · Jan 15, 2012

Currently you will need to use the TEXT input mode.
