How to make a smaller RatingBar?


Question

I've added a RatingBar in a layout:

<RatingBar 
    android:id="@+id/ratingbar"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:numStars="5"
    android:stepSize="1.0"
    />  

But the default style for the rating bar is too large.
I've try to change it by adding the android style : style="?android:attr/ratingBarStyleSmall"

But the result is too small and it's impossible to set a rate with this property.

How could I do?

Accepted Answer

The default RatingBar widget is sorta' lame.

The source makes reference to style "?android:attr/ratingBarStyleIndicator" in addition to the "?android:attr/ratingBarStyleSmall" that you're already familiar with. ratingBarStyleIndicator is slightly smaller but it's still pretty ugly and the comments note that these styles "don't support interaction".

You're probably better-off rolling your own. There's a decent-looking guide at http://kozyr.zydako.net/2010/05/23/pretty-ratingbar/ showing how to do this. (I haven't done it myself yet, but will be attempting in a day or so.)

Good luck!

p.s. Sorry, was going to post a link to the source for you to poke around in but I'm a new user and can't post more than 1 URL. If you dig your way through the source tree, it's located at frameworks/base/core/java/android/widget/RatingBar.java

How to glue the code given here ...

Step-1. You need your own rating stars in res/drawable ...

A full star

Empty star

Step-2 In res/drawable you need ratingstars.xml as follow ...

<?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_empty" />
    <item android:id="@android:id/secondaryProgress"
          android:drawable="@drawable/star_empty" />
    <item android:id="@android:id/progress"
          android:drawable="@drawable/star" />
</layer-list>

Step-3 In res/values you need styles.xml as follow ...

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="foodRatingBar" parent="@android:style/Widget.RatingBar">
        <item name="android:progressDrawable">@drawable/ratingstars</item>
        <item name="android:minHeight">22dip</item>
        <item name="android:maxHeight">22dip</item>
    </style>
</resources>

Step-4 In your layout ...

<RatingBar 
      android:id="@+id/rtbProductRating"
      android:layout_height="wrap_content"
      android:layout_width="wrap_content"
      android:numStars="5"
      android:rating="3.5"
      android:isIndicator="false"
      style="@style/foodRatingBar"    
/>
