Try changing style

 <RatingBar
        android:layout_width="wrap_content"
        android:rating="4.5"
        style="@style/Base.Widget.AppCompat.RatingBar.Small"
        android:layout_height="wrap_content" />

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>

Answer 3

I've searched through a lot of posts with the same question here and I was trying out the answer provided by @Vaibhav A. Jani, when I just stopped by a more simple solution to this question. I am not saying that @Vaibhav A. Jani answer is not correct tho.

Try this, it worked for me to see stars much smaller:

RatingBar ratingBar = new RatingBar(context, null, android.R.attr.ratingBarStyleSmall);

And also I was able to create lots of RatingBar dynamically, without touching any xml file, just java coding.

            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:numStars="5"
