InputTransparent property makes all children disabled

EitanRa commented 1 month ago

Description

Converting a Xamarin.Forms project to .NET MAUI, i'm facing a problem with a Microsoft.Maui.Controls.Maps.Map inside a ScrollView. In my Xamarin version, I set the ScrollView's InputTransparent property to true and everything worked well - the scroll view could scroll, the controls inside it responded to user input (button click and so on) and the map could scroll as well, without interrupts from its scroll view parent. But now in MAUI, after setting ScrollView's InputTransparent property to true (or any other view's InputTransparent property), the result is just as same as setting its IsEnabled property to true - all of the views inside the scroll view won't respond to any input! Here's the code: public class MyPage : ContentPage { public MyPage() { var sl = new StackLayout { Children = { new Button(), new Map() } }; Content = new ScrollView { InputTransparent = true, Content = sl }; return; } }

UPDATE: Found a solution for Android. Paste this code in MainActivity: `public override bool DispatchTouchEvent(MotionEvent e) { if (e.Action == MotionEventActions.Down || e.Action == MotionEventActions.Move || e.Action == MotionEventActions.Up) { // search MapView Control var maps = (Window.DecorView as ViewGroup).GetChildrenOfType();

    foreach (var map in maps)
    {
        // initialize MapView screen position 
        int[] pos = new int[2];

        // set MapView screen position
        map.GetLocationOnScreen(pos);

        // create hit test rectangle
        Rect hitRect = new Rect(pos[0], pos[1], pos[0] + map.Width, pos[1] + map.Height);

        // judge hit test
        bool isHitTest = hitRect.Contains((int)e.GetX(), (int)e.GetY());

        // hit test result is OK
        if (isHitTest)
        {
            // touch event intercept
            map.Parent.RequestDisallowInterceptTouchEvent(true);
        }
    }
}

return base.DispatchTouchEvent(e);

}` (source: https://github.com/dotnet/maui/issues/13628)
