The solution worked fine but the divider color is still blue. Var m圜ustomCell = sender as CustomImageCell Color inversion applies to everything on your. Colors dont change in media, such as videos. If (args.PropertyName = CustomImageCell.IsSelectedPropertyName) Dark theme applies to the Android system UI and supported apps. Protected override void OnCellPropert圜hanged(object sender, 圜hangedEventArgs args)īase.OnCellPropert圜hanged(sender, args) This.cell = base.GetCellCore(item, convertView, parent, context) Protected override global:: GetCellCore(Cell item, global:: convertView, ViewGroup parent, Context context) When the item is tapped you have to set IsSelected, then you can do something like this in your renderer: public class CustomImageCellRenderer : ImageCellRenderer This.SelectedBackgroundColor = Color.Red This.OnPropert圜hanged(IsSelectedPropertyName) Public const string IsSelectedPropertyName = "IsSelected"
To make this easier to implement, Colors offers a primarySurface color which provides exactly this behaviour and these components use by default. Thankfully, things are slightly better now. Raise Propert圜hanged event when IsSelected changed public class CustomImageCell : ImageCell A common pattern is to color a container primary color in light theme and surface color in dark themes many components use this strategy by default e.g. android button color Use backgroundTint I find changing button color is one of the most difficult things to do right in Android when I first started programming for Android 2.2 (API Level 8). Define a "IsSelected" property on your cell.I didnt actually test it, but this could work:
