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 开发者_开发技巧to set a rate with this property.

How could I do?

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"    
/>

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.)

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

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"

---

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" 
    />

---

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" />

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).

 <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"

---

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

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

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" />

---

<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" />

The Best Answer for small ratingbar

<RatingBar
                    android:layout_width="wrap_content"
                    style = "?android:attr/ratingBarStyleSmall"
                    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" />

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.
