I am looking for "Highlight the Picker with Background color whenever it is clicked" and also "Title Color"

And when i click other picker the previous picker has to be change to default color, and current clicked picker has to be change color.

I tried with PickerName.BackgroundColor property in code behind, but its not working properly, sometimes its not changing. Is there any other way or how to achieve this using custom renderer or anything?. Thanks in advance.

We can change BackgroundColor in SelectedIndexChanged event in PCL.

picker.SelectedIndexChanged += (sender, args) =>
 {
     picker.BackgroundColor=Color.Red;
 };

(or)

We can achieve this through CustomRenderer.

Find Override method for Picker Selection in Xamarin.iOS and put that override method in CustomRenderer and in that change the background color

try below code 

Device.BeginInvokeOnMainThread(() =>
{
  picker.BackgroundColor = Color.Red;
  picker.TextColor=Color.Pink;
});
