ratingbar can not show current numStars

I have a RatingBar and use the method setNumStars(final int numStars). in XML the code is like this :

 <RatingBar
                android:id="@+id/rating_bar"
                style="@style/CMYMyRatingBars"
                android:isIndicator="true"
                android:numStars="5"
                android:rating="5"
                />

then there is a problem . When the numStars is 0. My RatingBar will show 5 stars.

private RatingBar ratingBar;
private float ratingValue;

ratingBar = (RatingBar) findViewById(R.id.rating_bar);

ratingBar.setOnRatingBarChangeListener(new OnRatingBarChangeListener() {

            @Override
            public void onRatingChanged(RatingBar ratingBar, float rating, boolean fromUser) { 

                ratingValue = rating;

            }
        });

ratingBar.getRating();



<RatingBar
    android:id="@+id/rating_bar"
    style="@style/CMYMyRatingBars"
    android:isIndicator="true"
    android:numStars="0"
    android:rating="4"
     />

Because you have given the rating 5 that is why it is showing 5 rating when you are giving 0 numStars. I have executed this code and code is working fine.You have to see zero rating then implement this code.

<RatingBar
    android:id="@+id/rating_bar"
    style="@style/CMYMyRatingBars"
    android:isIndicator="true"
    android:numStars="0"
    android:rating="0"
     />

styles

<style name="CMYMyRatingBars" parent="@android:style/Widget.RatingBar">
        <item name="android:progressDrawable">@drawable/ratingbar</item>
        <item name="android:layout_width">wrap_content</item>
        <item name="android:layout_height">35dp</item>
        <item name="android:gravity">center</item>
    </style>

ratingbar.xml

<item
    android:id="@+android:id/background"
    android:drawable="@drawable/ratingbar_empty"/>
<item
    android:id="@+android:id/secondaryProgress"
    android:drawable="@drawable/ratingbar_empty"/>
<item
    android:id="@+android:id/progress"
    android:drawable="@drawable/ratingbar_filled"/>

ratingbar_filled.xml

<item android:drawable="@drawable/ratingbar_staron" android:state_pressed="true" android:state_window_focused="true"/>
<item android:drawable="@drawable/ratingbar_staron" android:state_focused="true" android:state_window_focused="true"/>
<item android:drawable="@drawable/ratingbar_staron" android:state_selected="true" android:state_window_focused="true"/>
<item android:drawable="@drawable/ratingbar_staron"/>

ratingbar_empty.xml

<item android:drawable="@drawable/ratingbar_staroff" android:state_pressed="true" android:state_window_focused="true"/>
<item android:drawable="@drawable/ratingbar_staroff" android:state_focused="true" android:state_window_focused="true"/>
<item android:drawable="@drawable/ratingbar_staroff" android:state_selected="true" android:state_window_focused="true"/>
<item android:drawable="@drawable/ratingbar_staroff"/>
