Edit:
To add the below code to a ListView.DataTemplate, you would want to do something like this:
ListView listView = new ListView {
SeparatorColor = Color.Green,
ItemsSource = ListlvData
};
listView.ItemTemplate = new DataTemplate(() => {
ViewCell cell = new ViewCell();
cell.Tapped += (sender, args) => {
cell.View.BackgroundColor = Color.Red;
OnListViewTextCellTapped(cell); //Run your actual `Tapped` event code
cell.View.BackgroundColor = Color.Default; //Turn it back to the default color after your event code is done
};
cell.View = new Image();
return cell;
});
To change the background color on Tapped you will need to use a ViewCell and an Image control within that since ImageCell does not support BackgroundColors by default.
I put a StackLayout within the ViewCell but then on the Tapped event, I change the ViewCell.View's BackgroundColor, like so:
ViewCell cell = new ViewCell();
cell.Tapped += (sender, args) => {
cell.View.BackgroundColor = Color.Red;
OnListViewTextCellTapped(cell); //Run your actual `Tapped` event code
cell.View.BackgroundColor = Color.Default; //Turn it back to the default color after your event code is done
};
