Android RatingBar可以'；t集额定值

我试图在我的Android应用程序中实现一个分级栏，但在设置分级时遇到了一些问题。“我的酒吧”始终显示为具有最大可用评级。以下是我的档案：

styles.xml

<style name="ratingBarStyling" parent="@android:style/Widget.RatingBar">
    <item name="android:progressDrawable">@drawable/star_rating_bar</item>
    <item name="android:indeterminateDrawable">@drawable/star_rating_bar</item>
    <item name="android:minHeight">25dip</item>
    <item name="android:maxHeight">27dip</item>
</style>

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="@+id/background"
    android:drawable="@drawable/star_rating_bar_full_empty" />
<item android:id="@+id/secondaryProgress"
    android:drawable="@drawable/star_rating_bar_full_empty" />
<item android:id="@+id/progress"
    android:drawable="@drawable/star_rating_bar_full_filled" />
</layer-list>

@可拉拔/星形额定值杆

25度
27dip

（与v21相同）

star\u rating\u bar.xml

<style name="ratingBarStyling" parent="@android:style/Widget.RatingBar">
    <item name="android:progressDrawable">@drawable/star_rating_bar</item>
    <item name="android:indeterminateDrawable">@drawable/star_rating_bar</item>
    <item name="android:minHeight">25dip</item>
    <item name="android:maxHeight">27dip</item>
</style>

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="@+id/background"
    android:drawable="@drawable/star_rating_bar_full_empty" />
<item android:id="@+id/secondaryProgress"
    android:drawable="@drawable/star_rating_bar_full_empty" />
<item android:id="@+id/progress"
    android:drawable="@drawable/star_rating_bar_full_filled" />
</layer-list>

星级评定栏满空

<?xml version="1.0" encoding="utf-8"?>
<selector
xmlns:android="http://schemas.android.com/apk/res/android">

<item android:state_pressed="true"
    android:state_window_focused="true"
    android:drawable="@drawable/ic_star_empty" />

<item android:state_focused="true"
    android:state_window_focused="true"
    android:drawable="@drawable/ic_star_empty" />

<item android:state_selected="true"
    android:state_window_focused="true"
    android:drawable="@drawable/ic_star_empty" />

<item android:drawable="@drawable/ic_star_empty" />

</selector>

星级评定栏满

<?xml version="1.0" encoding="utf-8"?>
<selector
xmlns:android="http://schemas.android.com/apk/res/android">

<item android:state_pressed="true"
    android:state_window_focused="true"
    android:drawable="@drawable/ic_star" />

<item android:state_focused="true"
    android:state_window_focused="true"
    android:drawable="@drawable/ic_star" />

<item android:state_selected="true"
    android:state_window_focused="true"
    android:drawable="@drawable/ic_star" />

<item android:drawable="@drawable/ic_star" />

</selector>

最后，在片段布局上实现分级栏：

<RatingBar
        style="@style/ratingBarStyling"
        android:id="@+id/venue_card_rating"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center_horizontal"
        android:layout_marginTop="20dp"
        android:numStars="5"
        android:stepSize="1.0"
        android:rating="2.0"/>

现在由于某种原因，我可以看到填充的星形图标，但没有看到空的。我也尝试过以编程方式设置它，但结果是一样的。任何帮助都将不胜感激

这就是我经常听到的：

你犯了一个小错误/打字错误 您将不得不使用android:id，而不是提供新的id

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">

        android:drawable="@drawable/star_rating_bar_full_empty" />
    <item android:id="@android:id/secondaryProgress"
        android:drawable="@drawable/star_rating_bar_full_empty" />
    <item android:id="@android:id/progress"
        android:drawable="@drawable/star_rating_bar_full_filled" />
</layer-list>
