複数の評価バーの値を取得し、使用できる星の数に制限を設定する

Question

私は4つの評価バー（それぞれ4つの星がある）を持つプロジェクトで作業しています。すべての評価バーから組み合わせた「星」。私は今、値を追加しようとしていますが、それでもうまくいきません。すべての値を合計して、すべての評価で設定可能な値の数を制限できるようにします。

FragmentRatings.java：

`public class FramentRatings extends Fragment{ 
    RatingBar rbStrength, rbIntellect, rbWisdom, rbDexterity; 
    TextView tvPointSpent; 
    float pointsS, pointsI, pointsW, pointsD, total; 

    private SharedPreferences prefs; 

    @Nullable 
    @Override 
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, Bundle savedInstanceState) { 
     View view = inflater.inflate(R.layout.fragment_ratings, container, false); 

     rbStrength = (RatingBar)view.findViewById(R.id.strengthRating); 
     rbIntellect = (RatingBar)view.findViewById(R.id.intellectRating); 
     rbWisdom = (RatingBar)view.findViewById(R.id.wisdomRating); 
     rbDexterity = (RatingBar)view.findViewById(R.id.dexterityRating); 


     tvPointSpent = (TextView)view.findViewById(R.id.tvPointsSpend); 

     rbStrength.setOnRatingBarChangeListener(new RatingBar.OnRatingBarChangeListener() { 
      @Override 
      public void onRatingChanged(RatingBar ratingBar, float rating, boolean fromUser) { 
       tvPointSpent.setText(""+rbStrength.getRating()); 
       pointsS = rbStrength.getRating(); 
      } 
     }); 

     rbIntellect.setOnRatingBarChangeListener(new RatingBar.OnRatingBarChangeListener() { 
      @Override 
      public void onRatingChanged(RatingBar ratingBar, float rating, boolean fromUser) { 
       //tvPointSpent.setText(""+rbIntellect.getRating()); 
       pointsI = rbIntellect.getRating(); 
      } 
     }); 

     rbWisdom.setOnRatingBarChangeListener(new RatingBar.OnRatingBarChangeListener() { 
      @Override 
      public void onRatingChanged(RatingBar ratingBar, float rating, boolean fromUser) { 
       //tvPointSpent.setText(""+rbStrength.getRating()); 
       pointsW = rbWisdom.getRating(); 
      } 
     }); 

     rbDexterity.setOnRatingBarChangeListener(new RatingBar.OnRatingBarChangeListener() { 
      @Override 
      public void onRatingChanged(RatingBar ratingBar, float rating, boolean fromUser) { 
       //tvPointSpent.setText(""+rbStrength.getRating()); 
       pointsD = rbDexterity.getRating(); 
      } 
     }); 

     total = pointsD + pointsI + pointsS + pointsW; 

     tvPointSpent.setText(""+pointsS); 

     return view; 
    } 
}`

が間違ったロジックを得たが、すべきではないラインがあるとします。

tvPointSpent.setText（ "" + poin tsS）;

こと：

tvPointSpent.setText（String.valueOf）（合計）。
