如何解决带有自定义可绘制的评级栏不显示半星仅全星

你好，我有一个带有自定义可绘制的评分栏，但它只显示满星而不显示一半 这是我的代码，我该如何解决？

<layer-list xmlns:android="http://schemas.android.com/apk/res/android">

<item
    android:id="@android:id/background"

    android:drawable="@drawable/empty_star" />
<item
    android:id="@+id/secondaryProgress"

    android:drawable="@drawable/empty_star" />

<item
    android:id="@android:id/progress"

    android:drawable="@drawable/filled_star" />

<style name="doctor_rating" parent="@style/Widget.AppCompat.ratingBar">
    <item name="android:minHeight">13dp</item>
    <item name="android:minWidth">65dp</item>
    <item name="android:numStars">5</item>
    <item name="android:progressDrawable">@drawable/custom_rating_stars</item>
    <item name="android:stepSize">.1</item>
</style>


     
                    <ratingBar
                    android:id="@+id/doctor_rating_bar"
                    style="@style/doctor_rating"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:layout_alignParentStart="true"
                    android:layout_centerVertical="true"
                    android:layout_gravity="end"
                    android:rating="3.5"
                    />

解决方法

试试这个：

<style name="doctor_rating" parent="android.widget.RatingBar">
<item name="android:minHeight">13dp</item>
<item name="android:minWidth">65dp</item>
<item name="android:numStars">5</item>
<item name="android:progressDrawable">@drawable/custom_rating_stars</item>
<item name="android:stepSize">0.1</item>
