StarBar

A custom View class implementing a rating bar with 10 stars. The user can touch or swipe to select a rating between 1 and 10. The StarBar supports three rating ranges (red, yellow and green) that are indicated by different colored stars.

Usage

For a working example of how to use StarBar see the Android project in the sample folder.

1. Including the StarBar library project

StarBar is provided as an Android library project. See the Android developer website for information on how include and use library projects.

Referencing a Library Project

**2. Add StarBar to your layout**

    <com.badoo.starbar.StarBar
        android:id="@+id/starBar"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true" />

</RelativeLayout>

There are some restrictions on what you can specify for layout_width and layout_height.

  • layout_width must either be match_parent / fill_parent or fixed width.
  • layout_height must be wrap_content.

**3. Configuring rating ranges**

StarBar has three rating ranges. These ranges control what colour should be used when the rating stars are drawn. By default the following ranges are used:

  • 1-3: Red
  • 4-6: Yellow
  • 7-10: Green

If you want to override these are use different ranges it can be done by calling the following method in RatingBar.

public void setRanges(int yellow, int green)

Example: To set the ranges to the defaults listed above use:

starBar.setRanges(4, 7);

**4. Setting a listener to handle rating callbacks**

After adding the StarBar to your layout it should already work but it will not do anything when the user picks a rating.

StarBar starBar = (StarBar) findViewById(R.id.starBar);
starBar.setOnRatingSliderChangeListener(new OnRatingSliderChangeListener() {

    @Override
    public boolean onStartRating() {
        // The user has initiated a rating by touching the StarBar. This call will
        // immediately followed by a call to onPendingRating with the initial rating
        // value.   
    }

    @Override
    public void onPendingRating(int rating) {
        // This method will first be called when the user initiates a rating and then
        // subsequently as the rating is updated (by the user swiping his finger along 
        // the bar).
    }

    @Override
    public void onFinalRating(int rating, boolean swipe) {
        // If the rating is completed successfully onFinalRating is called with the
        // final result. The swipe parameter specifies if the rating was done using
        // a tap (false) or a swipe (true).
    }

    @Override
    public void onCancelRating() {
        // Called if the user cancels the rating by swiping away from the StarBar and releasing.
    }
});
