Android Question [SOLVED] How to implement Theme.MaterialComponents.DayNight ?

[zolive33]

Hi,

I would like to use Material Design components for Android (https://material.io/).
In the manifest editor, I declare :

CreateResource(values-v25, theme.xml,
<resources>
    <style name="Theme.MyApp" parent="Theme.MaterialComponents.DayNight">
        <!-- ... -->
    </style>
</resources>
)

But I have an error when I build sample projet. I think I have checked everything, so I dont no why
Can anyone help me ? thanks in advance. ?

I add an example to test, and the list of installed components.

Best practice for Android Dark theme?

Hi all, I have a question concerning the Dark theme that has been introduced with Android 10. What is the best practice to support Dark themes in B4A? How can I select an image based on the night mode flag? thanks a lot, Johannes

thank you for your response, but I develop a library that uses new Material Components theme attributes.
So I can't use AppCompat themes.

Finally I found the solution: I put "sdk manager" back in its original configuration.
I added the libraries "androidx.annotation:annotation-experimental" and "androidx.viewpager2:viewpager2". And now I can Build

Problem solved

Note that if you want to use newer versions of material components, you might need to manually install and modify dependencies. As far as I know, the sdk manager doesn't always let you install the newer dependencies.

For example, I've had to do that for constraintlayout 2.0.1, which is required for v1.3.0 of material components. You can download these from google maven, place them in your android skd folder under extras\b4a_remote and edit installed-components.txt to reflect the changes you made.

This should work for up to v1.4.0. For v1.5.0 you have to change the targetSdkVersion to 31, which I don't know if B4A supports at this point.

Hi,

Here is an example. You will find:

• An extract of the source code
• The library and
• An example of use.

Create a B4X library with Android Studio - Step by step to integrate the library in an Android Studio project.

Best regards.

Best regards.

Works great. I think you should post the library in libraries thread and also, I hope you will wrap more material components views when you are free.

Yes of course
