    rb.setOnRatingBarChangeListener(new 
    RatingBar.OnRatingBarChangeListener(){
    @Override
    public void onRatingChanged(RatingBar ratingBar,float rating,boolean fromUser){
        value.setText("Rated:"+rating)}
    });

and this xml code

<RatingBar
      android:id="@+id/ratingBar"
      style="?android:attr/ratingBarStyleSmall"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:isIndicator="true"
      android:numStars="5"
      android:rating="4.5"
      android:stepSize="0.5" />

Answer 1

Try modify to this

 rb.setOnRatingBarChangeListener(new OnRatingBarChangeListener() {
        public void onRatingChanged(RatingBar ratingBar, float rating,
         boolean fromUser) {
         Toast.makeText(getApplicationContext(),"Your Selected Ratings  : " + String.valueOf(rating),Toast.LENGTH_LONG).show();
        }
  });

Answer 2

You can do like this.

<RatingBar
    android:id="@+id/ratingBar"
    style="?android:attr/ratingBarStyleSmall"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:isIndicator="false"
    android:numStars="5"
    android:rating="4.5"
    android:stepSize="0.5" />

<TextView
    android:id="@+id/textView23"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_weight="1"
    android:text="TextView" />

Just setting android:isIndicator="false" in the RatingBar

Then use in the Activity .

rb.setOnRatingBarChangeListener(new RatingBar.OnRatingBarChangeListener(){
    @Override
    public void onRatingChanged(RatingBar ratingBar,float rating,boolean fromUser){
        value.setText("Rated:"+rating)}
});
