Android RatingBar 无法设置评分

Question

我正在尝试在我的 Android 应用程序中实施 RatingBar，但我运行在尝试设置评级时遇到了一些问题。我的栏始终显示为具有最大可用评级。以下是我的文件：

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>

（v21 相同）

star_rating_bar.xml

<?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>

star_rating_bar_full_empty

<?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>

star_rating_bar_full_filled

<?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 Fragment 布局上实施 RatingBar：

<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，我可以看到实心星形图标，但看不到空心图标。我也尝试过以编程方式设置它，但结果是一样的。任何帮助将不胜感激。

你发小了mistake/typo 您将不得不使用 android:id 而不是提供新 ID。

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