B4A Library afollestad material-dialogs

tchart · Apr 22, 2015

Firstly, this is a work in progress but I thought I would share to get some feedback from the B4A community. Not all dialogs types are implemented yet.

This is a B4A wrapper library of Aidan Follestads Material Dialogs library on GitHub

His library supports material style dialogs all the way back to API level 8. If you would like to see examples of the library Aidan has an app on the Play Store (well worth downloading). The library is updated frequently.

Secondly this is similar to thedesolatesoul's MSMaterialDialogs library. He has provided great advice on the road to getting this library working. So thanks thedesolatesoul!

Thirdly, as with thedesolatesoul's MSMaterialDialogs library these dialogs are not modal and use callbacks (see the example project).

To get this running you need;

1) The wrapper library (download from here)
2) android-support-v4.jar (must be version 22.1 or later, use Android SDK-Manager to update your copy)
3) android-support-v7-appcompat.jar
4) android-support-v7-recyclerview.jar
5) The android.support.v7.appcompat additional resources
6) The afollestad_material-dialogs additional resources
7) All additional libraries must be in your B4A additional libraries folder
8) See note 1 below regarding dialog text colours (and themes).
9) Make sure that you reference a android.jar with platform version 21 or above in the IDE under the "Tools/Configure Paths" menu. (Thanks to corwin42)

Please refer to the sample project to see where to place the additional resources. The sample project uses a menu to initiate the dialogs.

NOTE 1: When using the library in your own app the dialog colours may not be the correct "Material" colours. The example app defines the correct colours via a theme under ..\MDTest\Objects\res\values\theme.xml (this file must be made read only otherwise it will be overwritten). Read this forum post for more info on themes.
NOTE 2: Please, please, please make sure you have version 22.1 or later of the support libraries and that the 3 libraries are copied to your additional libraries folder for B4A.

@tchart This bug has been fixed with release 0.8.5.8. Can you please recompile the library?

Will do. I've just rebuilt my laptop so am reinstalling the necessary software.

wimpie3 · May 24, 2016

I'm waiting patiently.

Very beautiful library. I have a question. When a dialog appear it can be close tapping outside the dialog. Is it possible to prevent this feature? I would like close the dialog only when pressing button on the dialog and not outside it.
Thanks

Sorry for the delay, I was struggling to find the support libraries as they are now hidden in the SDK manager (you need to turn on obsolete options).

The library compiled fine and the test app works as expected. I have not done extensive testing or added any new functions.

Will this work for custom dialogs?

trueboss323, the actual library does support custom dialogs but the B4A wrapper does not implement this. I have not had much time to work on the library and also my B4A version is not up to date.

I tried using your library as a test sample and I wanted to display a simple message box. But I keep getting a android.content.res.Resources$NotFoundException: Resource ID #0x0 error. And my code looks like this:

B4X:

Dim MD As MD_BasicDialog
    MD.Initialize("MD")
    MD.Show("Test","test","ok","ok","",Null ,False,False)

So what is the correct way to use it?

Have you included the additional resources?

I haven't. It's working now, thank you!

Someone asked for the library source code. I've put it on GitHub if anyone wants to take a look;

One thing, I'd like to use this library on older Android versions. And on Android versions 5+ it should let it use the native material dialog, is it possible?
