Android Question dialog theme

[Stern0m1]

When I set the activity theme to dialog the views from the layout file dont show.
If I add them in code it works.

Is that the way B4A was designed?

Thanks

Maybe the activity size is zero at that point.

Try to add a panel in your code and load the layout into the panel after you added the panel to the activity.

I dont think the activity size is zero as I get a blank screen.

Any other ideas?

I am setting the the theme to dialog in the manifest editor with:

SetActivityAttribute(configuration,android:theme, "@android:style/Theme.Dialog")

This is not the main activity.

Could someone else try this and report back if the same thing happens?

Thanks

It loads only if #IncludeTitle: True , not if false. Is that by design or is that a bug? Thanks

Theme.Dialog is an Android 2 theme. I don't recommend you to use it. Your app will use the old Android 2 style and you will also encounter compatibility issue with newer devices.

How else can make an activity not full screen with the previous activity showing?

Why don't you use a regular panel?

I want to seperate it in a seperate activity.
Thanks

You can implement all the code in a class and then reuse the class (like AnotherDatePicker for example).

Ok. Will try that.
The dialog theme works fine on my Android 6.0. I have not done extensive testing. Are you sure that there will be issues on Androids greater than 2.0?
I cant find any reference on Androids website that this theme won't work with newer versions. Can you provide a reference?

Thanks

Can you educate me a bit about themes in general? The code for a theme lies in the android it self? Its not fully contained in the App? Is there some part of the os that it needs?

Trying to understand why it should make a difference which version Android.

Thanks

Theoretically it should work on all versions but it will use the Android 2 theme. Practically there are issues on some newer devices when you use the old themes.

These themes are part of the OS.
