Add the following assembly reference to the Android project:

[android\Syncfusion.SfRating.Andriod.dll]

Add and configure the SfRating control

• The following namespace needs to be added.

C#

using Com.Syncfusion.Rating;

• Create an instance for SfRating control, and add it to application.

C#

SfRating rating;
protected override void OnCreate(Bundle savedInstanceState)
{
    base.OnCreate(savedInstanceState);
    rating = new SfRating(this);
    SetContentView(rating);
}

Set number of rating items

The number of rating items to be displayed can be customized in the SfRating control. Users can create a rating application with 5 items as follows.
