The original link I posted is now broken (there’s a good reason why posting links only is not the best way to go). 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="android:style/Widget.Material.RatingBar.Small">
... // Additional customizations
</style>
// layout.xml
<RatingBar
android:id="@+id/ratingBar"
style="@style/customRatingBar"
... />
