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've mucked around with the reflector lib and added an on touch event. That only works when clicking on the spinner main box - it doesn't handle the itemclicked event I think that the only option that I can work with for now is to add an imageview to the right of the spinner and use that as the click event. The user will have to select from the drop down then click the image - better than reworking the form!

Hi There!

I am looking to make a modal dialog to enter a pin code. I got a printscreen from a youtube video of what i meant, it is attached.

I dont want to use the android keyboard.

I have not figured out using the dialog how to do that.

Thanks

If you have a specific need, you can do easily the same thing with two panels: one for the dialog, and one, behind, occupying the whole screen, to block touch events.

Thank You Informatix. After more searching i have found your library Floating window and that is helping me a lot.

I am using it to display the pind pad. I have created before it showing a semitransparent panel to somewhat hide the application behind. I am getting the OnMove event to force the windows to be pinned. There is no option to create a windows already pinned, only the user can do that.

I know you make this to be modaless, however what can be done for the user do not click on the other buttons behind?

Many thank for your source code, I am learning a lot from it.

Yes, I forgot to add this function. Since you have access to the source code, you can add it easily.

Place a panel between the floating window and the other views, and create a OnTouch handler for this panel (even empty).

Enhancement request

Hi agraham,

thanks for this fabulous library. Can I ask for a modification to the TimeDialog to allow the selection of seconds as well, thanks.

agraham · Oct 23, 2012

The TimeDialog uses the Android TimePickerDialog which I'm afraid doesn't support the selection of seconds. You will need to make a CustomDialog for that.

Change Size of ColorDialogHSV

I scrolled tyhrough most pages in this thread and couldnt find any mention of changing the overall size/scale of the color dialog box?

I love the layout as it is, except I would like to make it smaller overall.
Is there a syntax to set the size of the dialog - while still keeping the color bars etc all in scale?

Ideally I would like to make the entire dialog about 1/2 or 2/3 its defualt size.

Is there a way of doing this in the AGraham Dialogs library?

agraham · Oct 23, 2012

No. Android determines the size of the dialogs.

Resume after another activity

In a custom dialog that I have, I have a button that the user can press to take a photo. When that happens when the user presses the button is that the custom view is saved to a variable, then the photo activity is launched.

Once the user has taken a photo or cancelled it, the activity returns. The procedure that is called tries to restart the dialog using the standard dialog.show command. At this point I get an error as below:
"The specified child already has a parent. You must call removeView on the child's parent first."

Is there a way to redisplay the original dialog - it's almost as if it's open but just hidden from view. Even better would be not having it close in the first play but that seems to be impossible if loading another activity...

Regarsd,

Jon

Even with the dialog size fixed, its still a great library......thanks. I guess the alternative is to re-create a specific dialogue with a panel and separate controls and make that smaller.......a good learning activity forme. Thanks again.

Standard View?

Thanks for the reply, agraham.

Do you know of a "standard" view for the number selector in the dialogs? Or is it constructed on a listview or scrollview or similar?

would like to make the time selector with seconds look as uniform as possible with the other dialogs.

I really appreciate the time you all put into this forum, and the enhancements via libraries etc.

agraham · Oct 24, 2012

The numeric up-down is an internal Android View used by Android to implement the dialog. It is not available to programs. Look at the first answer here.

EDIT :- I've just noticed it is exposed in Android SDK 11 and up. It would need a library to wrap and expose it. There's a job for somebody.

arp · Oct 24, 2012

many thanks for the reply. seems a bit silly on Googles part not to expose standard UI elements - especially when they harp on about consistency of user experience etc.

Will see what I can get from that link - maybe time to figure out how to do libraries..... Thanks again. :sign0188:

Does CustomDialog2 have some sort of padding inside it? This is all I did.

B4X:

Dim cd As CustomDialog2, pnlone as Panel
pnlone.Initialize("")
pnlone.Color=Colors.Blue
cd.AddView(pnlone,468dip,400dip)
cd.Show("Dialog","","","",Null)

Here is the screenshot

Notice the gap on left and right edges? Why is this happening? I want the panel to fill from left edge to right edge.

Then I changed CustomDialog2 to CustomDialog and used cd.AddView(pnlone,0,0,468dip,400dip) instead. And this is what I got.

My device is Asus Transformer TF101 tablet running Android 4.0.3.

Read the docs: Basic4android - Dialogs
It says:

CustomDialog2

This modal dialog displays a custom set of controls laid out on a Basic4android Panel.
The Panel will be automatically centred in the displayed dialog.

CustomDialog2 centres things, while CustomDialog uses Absolute positioning.

agraham · Nov 1, 2012

From the xml for CustomDialog2

The Panel will be automatically centred in the displayed dialog.
