How to make RatingBar to show five stars

Question

I am following the standard example of how to add a RatingBar. To control the number of stars I tried to use android:numStars=\"5\". The problem is

Answer 1

I found that the RatingBar stretched to a maximum number of stars because it was enclosed in a Table with the attribute android:stretchColumns = "*".

Once I took stretchCoulumns off all columns, the RatingBar displayed according to the android:numStars value

Answer 2

You should just use numStars="5" in your XML, and set android:layout_width="wrap_content".
Then, you can play around with styles and other stuff, but the "wrap_content" in layout_width is what does the trick.

Answer 3

Even i was facing the issue @Roland , I had included one more attribute called

android:layout_alignParentRight="true" 

in my RatingBar declaration in XML. This attribute prevented from setting of the stars required and setting up the NumStars

Keep posted on the issues you come across !

Answer 4

To show a simple star rating in round figure just use this code

public static String getIntToStar(int starCount) {
        String fillStar = "\u2605";
        String blankStar = "\u2606";
        String star = "";

        for (int i = 0; i < starCount; i++) {
            star = star.concat(" " + fillStar);
        }
        for (int j = (5 - starCount); j > 0; j--) {
            star = star.concat(" " + blankStar);
        }
        return star;
    }

And use it like this

button.setText(getIntToStar(4));

<RatingBar
            android:id="@+id/rating"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            style="?android:attr/ratingBarStyleSmall"
            android:numStars="5"
            android:stepSize="0.1"
            android:isIndicator="true" />

in code

mRatingBar.setRating(int)

Answer 6

<RatingBar
                    android:id="@+id/ratingBar"
                    style="@style/custom_rating_bar"
                    android:layout_width="wrap_content"
                    android:layout_height="35dp"
                    android:clickable="true"
                    android:numStars="5" 
                    />

Configure the number of Stars in the XML file... No need to provide it in Styles or Activity/Fragment .... IMPORTANT: Make sure you Put the WIDTH as Wrap content and weights are not enabled
