Material Design RatingBar with better appearance, compatible with Android 3.0+.

• Consistent appearance on Android 3.0+.
• Extends framework RatingBar .
• Get the 2dp star border background as in Material Icons and Google apps.
• Correct custom tinting across platforms.
• Able to render correctly when layout_width is set to match_parent , as in Google Play Store.
• Able to scale correctly when layout_height is set to values other than 16dp, 36dp and 48dp.
• Able to display ratings such as 4.3 correctly, which will be filled to 4.5 by framework’s incorrect implementation.
• Avoid framework’s sunken half star visual glitch.
• Used as a drop-in replacement for framework RatingBar .

Simply replace your RatingBar with MaterialRatingBar , and remember to apply a corresponding style for correct behavior.

For example, to create a normal MaterialRatingBar :

In order to make your RatingBar take the correct and consistent size on all versions, you will always need to use one of the styles from this library. The trick inside it is android:minHeight and android:maxHeight that controls the drawable height.

You can checkout more small or indicator variants in styles.xml.

You can use app:mrb_fillBackgroundStars to control whether background stars are filled, otherwise it defaults to the same value as android:isIndicator which is the behavior of Google apps.

8 tint-related attributes such as app:mrb_progressTint and app:mrb_progressTintMode are also supported so that they can control the tinting of rating drawables. The default tint color is ?colorControlActivated , and the default tint mode is src_in .

An OnRatingChangeListener interface is also added to MaterialRatingBar , which enables callback while user is dragging, just as the listener in SeekBar .

For a detailed example, you can refer to the sample app’s layout, where you can find examples such as tinting and wide layout.

Filled star or star border

The framework’s RatingBar uses filling stars with grey color as track, however as per the Material Icons site, star border icons are given.

And as for the Google Play Store and Google I/O app, they are both using the star borders as track.

With Google’s design practice and aesthetic considerations taken into account, I decided to use the star border style.

Google Play Store has stars of optical size 24dp, while Google I/O app and framework Widget.Material.RatingBar.Indicator have stars of size 36dp (which are of optical size 30dp). (The framework’s default size of 64dp is ridiculously large and thus not taken into consideration.)

Also noticing that the Material Icons site gives icons of 24dp (optical 20dp) and 36dp (optical 30dp), I decided to stick to the 36dp approach which is also visually pleasant.

Star border width

The ring for radio button in Material Design has a width of 2dp, and with experiments on other border widths, I decided to adopt the 2dp border width.

The star border icon is drawn with the help of Inkscape, by downloading the star icon SVG from Material Icons, duplicating the outer border path of the star, setting a stroke of 4dp, running stroke to path on it, extracting the inner border path, and finally combining this path and the original outer border path.

Framework RatingBar gives erroneous rendering for RatingBar when layout_width is set to match_parent by tiling the stars without any gap. Since Google Play Store employed the wide design, I implemented it inside this library as well, so that match_parent will work properly for MaterialRatingBar .

Google Play Store and Google I/O app both used an implementation other than RatingBar , which means dragging on the bar across stars won’t work (it is the functionality of AbsSeekBar ). I think this is a handy way of interaction for users, and it enables the setting of 0 star which can be useful if you want to enable users to reset their rating to unrated.

Android Ratingbar Module

A RatingBar is an extension that shows a rating in stars. The user can touch/drag to set the rating when using RatingBar.

Accessing the ratingbar Module

To access this module from JavaScript, you would do the following:

The ratingbar variable is a reference to the Module object.

This module converts native Android ratingbar widget to Titanium component. (http://developer.android.com/reference/android/widget/RatingBar.html)

Sets the rating (the number of stars filled).

rating — The rating to set (Must be a floating point value).

Sets the step size (granularity) of this rating bar.

stepSize — The step size of this rating bar. For example, if half-star granularity is wanted, this would be 0.5 (Must be a floating point value).

The number of stars (or rating items) to show

stars — Must be an integer value, such as «100».

Whether this rating bar is an indicator (and non-changeable by the user).

isIndicator — Must be a boolean value, either «true» or «false».

Listener to be called when the rating changes(event.rating will give selected rating value)

Using Custom Resources

If you want to use custom resource in your App you can override default resource. For that you have to place your custom resource inside app_root/platform/android/res or app_root/modules/android/titutorial.ratingbar/0.1/platform/android/res in the same name.

For example, if you want to override star_on image you have to override your custom image with the same name star_on.png

Android Custom Ratingbar Tutorial Example | Change Custom Star Image

We will boxing with android custom Ratingbar tutorial in this article.

In this post, we will learn how to give custom size, color, image, style to the in built rating bar.

By default, rating bar will show star image to give ratings to the user. We will change this star image with our own custom image.

Changes in the styles are also required for this example. You need to give your specific style to the rating bar.

I have used android studio to develop this android custom ratingbar tutorial.

Output

Below video demonstrate the final output of this example.

Step 1. Add Custom Images

Create one fresh new android studio project to reduce the complexity.

Now we need to add our custom images which we will use to show the rating stars.

As you have already shown in the output video, that we are going to use black and red heart icon instead of star.

Number of red hearts represents the actual value of rating.

So download heart images by clicking the below link.

[sociallocker] Download hearts Images [/sociallocker]

Now add images in res-> drawable directory.

Images in drawable

Step 2. Making selector file

Now again in the drawable directory, create one xml file and give it a name “ratingbar_selector.xml”

Add following source code in it

We have added our custom images in this file. We will use this file in the styles.xml file where we have done coding for adding custom styles.

Step 3. Changing styles.xml

Open up styles.xml file which is located at values->styles.xml

Copy below code in this file

Here, I have added a custom style named “ImageRatingBar”.

I have defined the minimum and maximum height of the image here which is the same as the original size of the image.

I have also set the progress drawable. Progress drawable will control the look and feel of the rating bar when the user is sliding horizontally on the rating bar.

An xml drawablw file named “ratingbar_selector.xml” is used as the progress drawable file.

Step 4. Main Activity Updation

Last thing is to update both files of Main Activity: activity_main.xml and MainActivity.java

Make your activity_main.xml file’s code look like the below

Here, give your custom style to the rating bar.

Textview will show the current value of the rating bar.

Your source code for MainActivity.java is as following

Common Problems and It’s Solutions

Changing the size of rating images is very complex thing. There are many problems are there with it.

Sometimes rating bar shows more than five stars or sometimes it shows less than five stars. It all depends on the size of the image and also on the size of the rating bar. See the below image

Many times, the stars of the rating bar are stretched vertically due to sizing problems as per following image.

Visit this for describing this problem but unique solution is described below.

Solution

Sizes of images and rating bar needs to be appropriate with respect to each other.

For example, in our example, the size of heart image is 50 * 50 and the size(height and width) of the rating bar is “wrap_content”.

Actually, the perfect scenario is that you keep the height and width of the rating bar as “wrap_content” always and change the size of the image as per your requirements.

You can also have multiple images with various size according to mdpi, hdpi, xhdpi, xxhdpi, xxxhdpi as you have launcher images in mipmap folder.

Download Source Code For Android Custom RatingBar

Thank you very much for reading this tutorial.

Hope you have increased your knowledge after this example.
