Android Question B4A 13.4, Android 35 -> Screen size/display problems

[mw71]

Hi,

I have now updated to B4A 13.4 with Android 36 Platform.

My app still works with panels.
However, the panel (into which a scrollview is loaded and then the layout) is no longer limited at the top by the bar (StdActionBar) and at the bottom by the “Android keys,” but is stretched across the entire screen.

How can I fix this so that it is still limited at the top by the StdActionBar and at the bottom by the Android keys in Android 35? I would like to keep my theme.

In the manifest, I have the following:
SetApplicationAttribute(android:theme, “@style/MyTheme”)

and in the code, I can switch between "android:style/Theme.Holo.Light" and "android:style/Theme.Holo".

targetSdkVersion 35 and opting out of edge-to-edge enforcement

Starting from B4A v13.4, the default themes (Themes.LightTheme / Themes.DarkTheme) already include the snippet that opts out of edge-edge. You only need this if you use a customize theme. The recommended targetSdkVersion is presently 34, however if you like to experiment with v35 then your app...

@mcqueccu , thanks for your feedback.
I am familiar with Erel's post and have tried to find a solution using it, but unfortunately, I was not successful.
I suspect the reason is that I am not using the default themes (Themes.LightTheme/Themes.DarkTheme),
but rather the Holo themes, which I would like to continue using.
It may also be due to the panels (which I can't really believe).

Can you post your manifest

The theme (res.GetResourceId(“style”, “android:style/Theme.Holo.Light”) or res.GetResourceId(‘style’, “android:style/Theme.Holo”)
is stored in a file. When the app is launched, this value is read, stored in the int variable theme_value, and then the theme is set with the following code:

#if java
public void _onCreate() {
    if (_theme_value != 0)
        setTheme(_theme_value);
}
#end if

I hope I'm reading my code correctly. It's been a long time since I added this.

You are NOT using the edgetoedge code in your manifest which you should.

Changing the theme at runtime

The generated Holo theme does not have the edge to edge

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style
        name="DarkTheme" parent="@android:style/Theme.Holo">
    </style>

Theme Material has it

<resources>

    <style

        name="DarkTheme" parent="@android:style/Theme.Material">

Its time to leave your Holo theme, and upgrade your interface.
Also test with targetSdkVersion 35

I am well aware of that.
I tried to adapt my app accordingly.
Unfortunately, this was unsuccessful, which is why I asked the question.
I assume that it doesn't work because I am NOT using Themes.LightTheme/Themes.DarkTheme but the Holo Theme. According to what Erel wrote, the instructions only apply to LightTheme/DarkTheme (at least that's how I understood it).

The idea of testing Erel's code is a good one.

I now have the following in the manifest: CreateResourceFromFile(Macro, Themes.DarkTheme)

This basically works. I now need to look into the handling.
