[android] How to make a smaller RatingBar?

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?

I found an easier solution than I think given by the ones above and easier than rolling your own. I simply created a small rating bar, then added an onTouchListener to it. From there I compute the width of the click and determine the number of stars from that. Having used this several times, the only quirk I've found is that drawing of a small rating bar doesn't always turn out right in a table unless I enclose it in a LinearLayout (looks right in the editor, but not the device). Anyway, in my layout:

            <LinearLayout
                android:layout_width="wrap_content"
                android:layout_height="wrap_content" >
                <RatingBar
                    android:id="@+id/myRatingBar"
                    style="?android:attr/ratingBarStyleSmall"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:numStars="5" />
            </LinearLayout>

and within my activity:

    final RatingBar minimumRating = (RatingBar)findViewById(R.id.myRatingBar);
    minimumRating.setOnTouchListener(new OnTouchListener()
    { 
        public boolean onTouch(View view, MotionEvent event)
        { 
            float touchPositionX = event.getX();
            float width = minimumRating.getWidth();
            float starsf = (touchPositionX / width) * 5.0f;
            int stars = (int)starsf + 1;
            minimumRating.setRating(stars);
            return true; 
        } 
    });

I hope this helps someone else. Definitely easier than drawing one's own (although I've found that also works, but I just wanted an easy use of stars).

There is no need to add a listener to the ?android:attr/ratingBarStyleSmall. Just add android:isIndicator=false and it will capture click events, e.g.

<RatingBar
  android:id="@+id/myRatingBar"
  style="?android:attr/ratingBarStyleSmall"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:numStars="5"
  android:isIndicator="false" />

the small one implement by the OS

<RatingBar
    android:id="@+id/ratingBar"
    style="?android:attr/ratingBarStyleSmall"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" 
    />

 <RatingBar
                    android:rating="3.5"
                    android:stepSize="0.5"
                    android:numStars="5"
                    style = "?android:attr/ratingBarStyleSmall"
                    android:theme="@style/RatingBar"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"/>

// if you want to style 

 <style name="RatingBar" parent="Theme.AppCompat">
        <item name="colorControlNormal">@color/colorPrimary</item>
        <item name="colorControlActivated">@color/colorAccent</item>
    </style>

// add these line for small rating bar

style = "?android:attr/ratingBarStyleSmall"

Use This Code

<RatingBar
    android:id="@+id/ratingBarSmalloverall"
    style="?android:attr/ratingBarStyleSmall"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentRight="true"
    android:layout_centerVertical="true"
    android:layout_marginRight="30dp"
    android:isIndicator="false"
    android:numStars="5" />

apply this.

<RatingBar android:id="@+id/indicator_ratingbar"
    style="?android:attr/ratingBarStyleIndicator"
    android:layout_marginLeft="5dip"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center_vertical" />

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"    
/>  

<RatingBar
    android:id="@+id/ratingBar1"
    android:numStars="5"
    android:stepSize=".5"
    android:rating="3.5"
    style="@android:style/Widget.DeviceDefault.RatingBar.Small"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" />

I solve this issue the following: style="?android:attr/ratingBarStyleSmall"

<RatingBar
    android:id="@+id/rating_bar"
    style="@style/Widget.AppCompat.RatingBar.Small"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" />

use the following code for small rating bar with onTouch event

enter code here


<RatingBar
            android:id="@+id/ratingBar"
            style="?android:ratingBarStyleSmall"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:isIndicator="false"
            android:rating="4"
            android:stepSize="0.5" />

Just use:

android:scaleX="0.5"
android:scaleY="0.5"

Change the scale factor according to your need.

In order to scale without creating a padding on the left also add

android:transformPivotX="0dp"

After a lot of research I found the best solution to reduce the size of custom rating bars is to get the size of progress drawable in certain sizes as mentioned below :

xxhdpi - 48*48 px

xhdpi - 36*36 px

hdpi - 24*24 px

And in style put the minheight and maxheight as 16 dp for all Resolution.

Let me know if this doesn't help you to get a best small size rating bars as these sizes I found very compatible and equivalent to ratingbar.small style attribute.

although answer of Farry works, for Samsung devices RatingBar took random blue color instead of the defined by me. So use

style="?attr/ratingBarStyleSmall"

instead.

Full code how to use it:

<android.support.v7.widget.AppCompatRatingBar
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                style="?attr/ratingBarStyleSmall" // use smaller version of icons
                android:theme="@style/RatingBar"
                android:rating="0"
                tools:rating="5"/>

<style name="RatingBar" parent="Theme.AppCompat">
        <item name="colorControlNormal">@color/grey</item>
        <item name="colorControlActivated">@color/yellow</item>
        <item name="android:numStars">5</item>
        <item name="android:stepSize">1</item>
    </style>

The best answer I got

  <style name="MyRatingBar" parent="@android:style/Widget.RatingBar">
    <item name="android:minHeight">15dp</item>
    <item name="android:maxHeight">15dp</item>
    <item name="colorControlNormal">@color/white</item>
    <item name="colorControlActivated">@color/home_add</item>
</style>

user like this

<RatingBar
                style="?android:attr/ratingBarStyleIndicator"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:isIndicator="false"
                android:max="5"
                android:rating="3"
                android:scaleX=".8"
                android:scaleY=".8"
                android:theme="@style/MyRatingBar" />

Increase/Decrease sizes by using scaleX and scaleY value

Its working for me in rating bar xml style="?android:attr/ratingBarStyleSmall" add this.it will work.

The Best Answer for small ratingbar
