Android Question Changing colorAccent, colorPrimary, etc at runtime

[trueboss323]

Hi all,
In my app I give the user the option to change the theme, when the user selects a theme then I would like to programmatically change all the accent,primary, text and dialog colors in the app. How can I achieve this?

You cannot change those values programmatically. You can change the complete theme: https://www.b4x.com/android/forum/threads/changing-the-theme-at-runtime.57277/#content

Hi Erel,
I used the code that you mentioned in the thread. But when using with AppCompact it does not display correctly, see attached screenshot. I tried changing to white material theme as an example. As a result, it adds a second action bar, and it turns the checkboxes black and buttons white making it harder to see.

Can you upload this project?

Yes, I've uploaded a small project that demonstrates this problem. On the dropdown menu, simply select 'Light' and you will see it reproduce.

I see it too. I'm not familiar with AppCompat implementation but it seems like the explicit setting of the theme conflicts with its implementation.

Perhaps it could be a bug with AppCompact? Maybe @corwin42 would know about it.

You set the Theme to Theme.Material.Light which is not an Appcompat theme.

AppCompat can only work with an Appcompat theme.

Hi corwin, do you know what are the list of AppCompact themes I can choose from?
