android垂直比率条大小问题

我已经垂直排列了分级栏，但这样做，我在管理屏幕上所需大小的分级栏时遇到了问题。我尝试使用提供的图像和默认评级栏进行自定义。但他们都没有帮我

到目前为止，我所做的工作如下：

1） Styles.xml

<style name="foodRatingBar" parent="@android:style/Widget.RatingBar">
        <item name="android:progressDrawable">@drawable/star_rating_bar_full</item>
        <item name="android:minHeight">48dip</item>
        <item name="android:maxHeight">48dip</item>
    </style>

6） 图像/图标如下所示：

7） 布局，其中我使用了带有样式的分级栏

    <com.navrideclient.widgets.VerticalRatingBar     
    style="@style/foodRatingBar"       
    android:id="@+id/ratingBar_car"  
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content"
    android:layout_gravity="center_horizontal"  
    android:numStars="5"  
    android:stepSize="1.0" />

<?xml version="1.0" encoding="utf-8"?>

<!-- This is the rating bar drawable that is used to
 show a filled cookie. -->
<selector
xmlns:android="http://schemas.android.com/apk/res/android">

<item android:state_pressed="true"
      android:state_window_focused="true"
      android:drawable="@drawable/star2" />

<item android:state_focused="true"
      android:state_window_focused="true"
      android:drawable="@drawable/star2" />

<item android:state_selected="true"
      android:state_window_focused="true"
      android:drawable="@drawable/star2" />

<item android:drawable="@drawable/star2" />

</selector>

<?xml version="1.0" encoding="utf-8"?>

 <!-- This is the rating bar drawable that is used to
 show a unfilled cookie. -->
<selector

<item android:state_focused="true"
      android:state_window_focused="true"
      android:drawable="@drawable/star1" />

<item android:state_selected="true"
      android:state_window_focused="true"
      android:drawable="@drawable/star1" />

<item android:drawable="@drawable/star1" />
