B4A Library [Lib] BetterDialogs

Informatix · Jul 4, 2013

I tried to improve the most useful dialogs of the Dialogs library. In my version, HTML tags are interpreted (even in the text of buttons), the InputBox uses a Masked EditText and has more options, you can check if the input is valid before closing the dialog, and the CustomDialog is fully customizable. I also solved an issue with the virtual keyboard.

MsgBox (under Gingerbread and JellyBean):

InputBox (under Gingerbread and JellyBean):

CustomDialog (under Gingerbread and JellyBean):

Another CustomDialog (under Gingerbread and JellyBean):

v1.1:
- I added a CloseDialog function;
- I added a margin parameter to the custom dialog.

v1.2:
- I fixed a bug in InputBox when there's a default value;
- I added the BackKeyPressed event for custom dialogs.

v1.3:
- I added a PasswordMode option to the InputBox;
- I added a CancelOnTouchOutside option.

v1.4:
- I added a CursorPosition option to the InputBox.

v2.0:
- I moved the CustomDialog parameters to the BD_CustomDlgParams class.
- I added two new parameters: Duration and DialogGravity.
- I removed the Margin parameter and added the MarginHeight parameter (to be used when Gravity is set to TOP).
- The BodyWidth and BodyHeight parameters defines now accurately the size of the dialog body.

v2.1:
- I added a "closing" event raised just before a custom dialog is dismissed. You can cancel the closure by returning False.

v2.11:
- I added the "DlgResponse" parameter to the Closing event.

This library does not work with Android versions < 2.
It requires another library: Masked EditText

HI,
But how to setup the editing text color ? Sometimes the text is invisible over the same background color

I am getting an error on LoadDrawable. It says its a undeclared variable.

You probably changed something in the example and broke its code. Revert to the original version.

InputBox uses the default colors for its EditText. If you don't like these colors, create a custom dialog with your favourite ones. You can see such a dialog with an EditText in the demo.

Thanks. Is default color always OK for background color that can be changed by device user color scheme ?

AFAIK, yes because they are the default ones, but a test will give you a definitive answer.

Hi Informatix,
I am using a customdialog using your Betterdialogs library and I added a Customview to use the AnotherDatePicker to a layout which I show on the customdialog.
All works fine but when I tap on the customview, the AnotherDatePicker dialog shows behind the customdialog from Betterdialogs.

Any idea on how can I change that?
Please, find attached a modified version of the TestDialog demo that shows the exposed situation.

Thanks a lot in advance,

Ellis Lombert

Obviously, your AnotherDatePicker panel is added to the activity behind the modal dialog, and not to the panel of the dialog. You should ask why to his author. There's maybe a bug to identify the right parent or you did not set this AnotherDatePicker properly.

Hi

I have a small issue with adding a scrollview to a custom dialog box. The scrollview's panel loads a file containing 12 check boxes. (See zip file for full program.)

When the BodyHeight and BodyWidth options are set to 50% the list can be scrolled all the way down to expose the last check box.

When the BodyHeight and BodyWidth options are set to 80% the panel containing the buttons at the bottom of the dialog box partially cover the last options in the list.

Regards

Joe

The explanation is rather simple: 80%y is too much for you screen. The title and the buttons at the bottom have also a height and it must be taken into account. So 100%y - title height - buttons height > 80%y. The scrollview cannot be displayed entirely. Set the body height to 100%y - 100dip and that should be fine.

Thanks for the info.

Is there a way of finding out the height of the title and button panels?

For example: If I wanted to have the entire dialog box occupy 90%x and 90%y of the available screen, how would I size the scroll view accordingly?

No, but use the value in my previous post and that should be fine.

The safest method is to create your own title and buttons, so you can control their height, but it will be a bit difficult to reproduce exactly the appearance of titles and buttons of standard dialogs.

Thanks for the advice.

Is it possible when the keyboard pops-up there is no "Done" button?

It is replaced by Next or Return (next line) depending on the context. See this post to force it to Next:

How can this be applied to the BD textbox?

If you mean "to the EditText of the InputBox", then it's not needed. "Done" is what's expected. Why would you want to change it to Next?

I have a textbox in the same activity which needs "Done" and runs some code when Done is pressed.
However this code must not run when Done is pressed in the BD InputBox.

??? The BD is modal so when it is displayed, you cannot select an EditText outside of it. The soft keyboard will work only with the BD EditText while it's on screen. No confusion is possible.

In custom dialogs, is it possible to validate fields at the field level (e.g. lost focus) or before clicking OK?

Related question: Is it possible to enable/disable OK programmatically (e.g. if a field value is missing or not valid)?

Merci!

This question is related to the view that you use in your custom dialog, not the dialog itself, so I cannot give an answer.

Idem. That concerns the IME or the view, not the dialog.
