Android Question System font size problem

[Devv]

Hello

i am facing a weird problem with system font size

my app display a website in a webview

everything is working correctly if the system font is set to normal
if it is set to anything other than normal then stuff will go wrong


normal font

large font

at first i thought the problem is from the website , it appeared that the system font change does not affect websites (on browser) so everything was running smooth when viewing the website from the browser


how could i possibly fix this issue ?
can i disable changing font size for my app ?

any ideas are highly appreciated

Try to set Settings.SetTextZoom to 100 with WebViewExtras2.

WebViewExtras.GetSettings.SetTextZoom(100)

hello

i tried what you suggested but still the same result (nothing changed)

If there is a simple way to get the data (images and text) then you can use xCLV to create this layout natively. This way you will have full control over the layout.

unfortunately that is not possible

so there is no way to deny android from changing my app font size ?

i found https://stackoverflow.com/questions...-size-changing-effects-to-android-application

can we convert that to b4a ? or use java object ?

You can add this code, based on the solution from that link, to your activity:

#if Java
import android.content.*;
import android.content.res.*;
@Override
protected void attachBaseContext(Context newBase) {
    super.attachBaseContext(newBase);
    final Configuration override = new Configuration(newBase.getResources().getConfiguration());
    override.fontScale = 1.0f;
    applyOverrideConfiguration(override);
   BA.Log("attachBaseContext");
}
#End If

It will be called. It has no effect based on my test with Android 10.

Resetting it programmatically: https://www.b4x.com/android/forum/threads/get-size-of-system-font-in-use.28065/#post-181853 (will not affect WebView)

Curious, if you set system to Large font and view this same page in Chrome, what does it look like?

Did you try adding the ChromeClient to the webview using webviewextras:

wve.addWebChromeClient(wv, "WVE")

About that Java Inline code, I managed to make it work.
The secret is to force finish the Activity and restart it again, so that the new setting is applied.
Attached a test project demonstrating this possibility.
The size of the texts is applied to the whole app and the new setting has effect on every text object, even MsgBoxes
... EXCEPT toast messages

Thanks a lot, it seems to work fine everywhere!
I'm not interested in the toast message!
