How can I decrease the size of Ratingbar?

There are two ways you can do this.

You have to style the RatingBar with either ratingBarStyleSmall or a custom style inheriting from Widget.Material.RatingBar.Small (assuming you're using Material Design in your app).

Option 1:

<RatingBar android:id="@+id/ratingBar" style="?android:attr/ratingBarStyleSmall" ... />

Option 2:

// styles.xml<style name="customRatingBar" parent parent="android:style/Widget.Material.RatingBar.Small"> ... // Additional customizations</style> // layout.xml<RatingBar android:id="@+id/ratingBar" style="@style/customRatingBar" ... />
