DatePicker / TimePicker background - APK not working on Android 5 → Theme: Dark

[Anke]

I use Theme → Dark, but with the TimePicker & DatePicker I get this on Android 5.x devices:
Left: Companion / right: APK

timeDatePicker_background.aia (2.4 KB)

Most of the time @Boban has an idea or solution to these problems or hopefully someone else.
(Or did I miss something, maybe in the old forum?)

Is it this:

I already tried to change this ...

@Anke

Android 5.x devices

So you have multiple devices that have the same effect?

[Anke]

Yes, I have 3 test devices with Android 5.x (5.0, 5.1).

[Peter]

And when you use the datepicker outside of App Inventor on those phones it looks good i presume.

[Peter]

I just tried in Genymotion on a Nexus 5 with Android 5.1. I see what you mean.

[Anke]

I built the same project with Kodular: no issues!

But I have to create the app with AI2 because I am using an extension that uses the AndroidX libs (so Kodular is out). And I need the Dark mode (Theme: Dark) for various reasons.

Android 5.0 (Galaxy Note 3) - APK built with Kodular:

Btw, unfortunately this solution no longer works:

Decompile APK, go to folder → \res\drawable\
Find the file and edit it → abc_dialog_material_background.xml
Find and change from this

<solid android:color="@android:color/white" />
to this
<solid android:color="@color/material_grey_800" />
or this
<solid android:color="@color/background_floating_material_dark" />

I got this solution from @Boban, some years ago.

As far as I can see, there doesn't seem to be a (short-term) solution / workaround for Android 5. Therefore I will have to set the minSdkVersion = 23. Too bad. But maybe there is still hope in the near future / for the next AI2 update? @ewpatton

Hi Anke

... you could DIY your own pickers.

[Boban]

Try this one

ThemeDark.apk

[Anke]

Great, it works on Android 5.x.
What do you have to adjust to get that done?

[Boban]

As the previous approach, but I only changed the color in the same file name on \res\drawable-v21

[Anke]

@Boban

but I only changed the color in the same file name

It works perfectly. Many Thanks!
You're unbeatable in things like that.

I'll check tomorrow on my other test devices, if there are any problems with other Android versions (> Android 5) with this solution (workaround), but I don't thinks so.
