Erhalten Sie den Wert von mehreren Bewertungsbalken und setzen Sie eine Grenze für die Anzahl der Sterne

Question

Ich arbeite an einem Projekt mit Fragmenten, wo ich 4 Bewertungsbalken habe (mit jeweils vier Sternen) und der Benutzer kann nur 10 verbrauchen "Sterne" kombiniert aus allen Bewertungsbalken. Ich versuche gerade, die Werte zu addieren, aber selbst das funktioniert nicht. Ich möchte in der Lage sein, alle Werte zusammenzufassen und dann zu beschränken, wie viele Werte in allen Bewertungen festgelegt werden können.

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; 
    } 
}`

Answer 1

könnte die Logik falsch verstanden haben, sollte aber nicht die Linie:

tvPointSpent.setText ("" + poin tsS);

sein:

tvPointSpent.setText (String.valueOf (total));
