Problem in reducing size of Rating Bar.

Question

I want to reduce the size of the Rating bar, I got some style properties that do it, but they are out of the reach of user interaction they are just Indicator. So, please let me know how to reduce the size. Thanks in advance.

How to glue the code given here ...

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

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"    
/>  

Try Activity ....

package x.y;

import android.app.Activity;
import android.os.Bundle;

public class RatingBarDemo extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.product);

    }
}

With this layout product.xml ...

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:paddingTop="5dip"
    android:paddingBottom="5dip">
    <ImageView
        android:id="@+id/imgProduct"
        android:layout_width="50dip"
        android:layout_height="50dip" 
        android:src="@drawable/icon" 
        android:scaleType="centerCrop"
        />
    <RelativeLayout
        android:id="@+id/layProductInfo"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_toRightOf="@id/imgProduct"
        android:paddingLeft="5dip"
        android:paddingRight="0dip"
        android:paddingTop="5dip"
        android:paddingBottom="5dip">  
        <TextView
            android:id="@+id/tvProductName"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:text="Product Name"
            android:textSize="17dip" 
            />
        <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"
            android:layout_below="@id/tvProductName"
            />  
        <TextView
            android:id="@+id/tvPriceLabel"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:text="$45.87"
            android:layout_toRightOf="@id/rtbProductRating"
            android:layout_below="@id/tvProductName"
            android:paddingLeft="10dip"
            android:textSize="17dip" 
            />  
      </RelativeLayout>     
  </RelativeLayout>
