定製的RatingBar沒有表現出超過1星級

Question

我從this stackoverflow thread實現了自定義的評價欄未顯示即使我設置numStars 5不止一星或任何其他數量

這裏是代碼。

我正在使用矢量繪圖的圖像。

的RatingBar在main_activity.xml

<RatingBar 
     android:id="@+id/ratingBarValue" 
     style="@style/Fuel_Indicator" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_gravity="center_horizontal" 
     android:numStars="5" 
     android:stepSize="1.0" 
     android:max="5" /> 

Fuel_Indicator風格樣式。

<style name="Fuel_Indicator" parent="@android:style/Widget.RatingBar"> 
    <item name="android:progressDrawable">@drawable/fuel_bar_full</item> 
    <item name="android:indeterminateDrawable">@drawable/fuel_bar_full</item> 
    <item name="android:minHeight">23dip</item> 
    <item name="android:maxHeight">25dip</item> 
</style> 

的fuel_bar_filled.xml

<layer-list xmlns:android="http://schemas.android.com/apk/res/android"> 
<item android:id="@android:id/background" 
    android:drawable="@drawable/fuel_bar_empty" /> 
<item android:id="@android:id/secondaryProgress" 
    android:drawable="@drawable/fuel_bar_empty" /> 
<item android:id="@android:id/progress" 
    android:drawable="@drawable/fuel_bar_filled" /> 

fuel_bar_empty.xml

<selector 
xmlns:android="http://schemas.android.com/apk/res/android">` 
<item android:state_pressed="true" 
    android:state_window_focused="true" 
    android:drawable="@drawable/ic_fuel_empty" /> 

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

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

<item android:drawable="@drawable/ic_fuel_empty" /> 
</selector> 

fuel_bar_filled.xml

<selector 
xmlns:android="http://schemas.android.com/apk/res/android">` 

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

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

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

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

</selector>

你的實現是完美的，但使用的是Vector Drawable這是造成這個問題。因此，要使用它，請嘗試在可繪製文件夾中將Vector Drawable替換爲png圖像，並查看它的工作原理。

您使用Vector Drawable與layer-list所以你Vector Drawable圖像是適合整個佈局嘗試png來取代它，這將解決您的問題。
