Problem with android popup

Android Popup Problem

The preview window on Android Maui popup is spreading out and not showing in the preview window. Is there any solution for that????

And I would like to ask for a list of available cameras to switch between.

if you report anything please at the very least provide some relevant code and ideally a reproduction. Remember: we do not have the context you have about your project, we have no idea what you’re trying to do, what your code looks like or what libraries you might be using.

In its current state this issue is far from actionable since I simply have no idea what you are talking about.

Other valuable information might be: what have you yourself already tried to resolve this? And what were the results of that?

Additionally, please stick with one topic per issue. Thanks!

Sorry about that.
The main problem is that it is like in the included test application of a popup with CommunityToolkit.Maui, and as you can see it is in the popup and spreads without getting outside of it.
They work fine on ios and windows but not on android.

Is there any reason to assume this is a bug with this library and not the Community Toolkit?

Yes, because when I also post it on the Main Page with a Grid with ColumnDefinitions and RowDefinitions ",200," it spreads out more than expected.

I'm experiencing the same problem. I have tried to experiment a little. I have managed to fix the problem by setting the scale type of the PreviewView to the FitCenter (it seems that default value is FillCenter, which causes overflowing beyond the view size).

CameraManager.android.cs

        public NativePlatformCameraPreviewView CreateNativeView()
        {
            _previewView = new PreviewView(Context.Context);
            _cameraExecutor = Executors.NewSingleThreadExecutor();

            // this line will make the preview to fit into the requested size of control and to overflow outside
            _previewView.SetScaleType(PreviewView.ScaleType.FitCenter);

            return _previewView;
        }

It would be great if the CameraBarcodeReaderView would have possibility to specify the ScaleType. Then I would not need to include full sources.
