Android Question Problem with ACToolBarDark (AppCompat with ToolBar) in layout.

[VeraVera]

Hi Erel

I indicate you the following problem.

I want to use the ACToolBarDark1 in my project but it only works as long as I call the layout from the Main module and not from another module.

If I try to make the layout call with ACToolBarDark1 from a module other than the Main module, I get the following error:

The code that I use in the main module replicates it in the new module.

My project requires many layouts and not all of them are going to need the side menu, so how can I use the ACToolBarDark1 in several layouts?

Using a ScrollView in the main layout (the one that is called from the main module) and loading a layout as needed is not viable since the actions of each layout would have to contain it in the main module and my project is very extensive.

I hope you can help me or guide me.

Thank you very much.

PD: I use B4A version 7.8

In your other module (which NEEDS to be an Activity) you need to use the same as in main. You need to extend the Activity to be an AppCompat Activity. Check AppCompat Tutorial

You're right.
I overlooked adding the extension in the activity.
Thank you.
