Возможно ли создать цикл в методе ArrayAdapter getView

Question

У меня есть глупый вопрос, вот мой класс LevelsAdapter для LinearLayout. Я использую его для отображения уровней в моей деятельности. В методе getView я использую «if (level.getLevel() == 1)», чтобы получить идентификатор уровня, я хочу спросить, можно ли создать цикл для этого? Было бы плохо с моей реализацией, если бы было 100 уровней или более для проверки.

private class LevelsAdapter extends ArrayAdapter<Level> { 

     private ArrayList<Level> levelsList; 

     public LevelsAdapter(Context context, int textViewResourceId,ArrayList<Level> levelsList) { 
      super(context, textViewResourceId, levelsList); 
      this.levelsList = new ArrayList<Level>(); 
      this.levelsList.addAll(levelsList); 
     } 

     private class ViewHolder { 
      TextView level; 
      TextView levelQuestionsCount; 
      TextView lockedLevelContainer; 
      Button start; 
      RelativeLayout levelLayout; 
      LinearLayout levelLayoutInner; 
      LinearLayout unlockedLevelContainer; 
      ImageView locklevel; 
     } 

     private void unlock(ViewHolder holder){ 
      holder.lockedLevelContainer.setVisibility(View.GONE); 
      holder.locklevel.setVisibility(View.GONE); 
     } 

     private void lock(ViewHolder holder, int toUnlock){ 
      holder.unlockedLevelContainer.setVisibility(View.GONE); 
      holder.lockedLevelContainer.setVisibility(View.VISIBLE); 
      holder.lockedLevelContainer.setText("Level is locked. Answer "+ (toUnlock - countSolved) +" questions to unclock."); 
      holder.locklevel.setVisibility(View.VISIBLE); 
     } 

     @Override 
     public View getView(int position, View convertView, ViewGroup parent) { 

      ViewHolder holder = null; 

      if (convertView == null) { 
       LayoutInflater vi = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
       convertView = vi.inflate(R.layout.level1, null); 

       holder = new ViewHolder(); 
       holder.level = (TextView) convertView.findViewById(R.id.level); 
       holder.levelQuestionsCount = (TextView) convertView.findViewById(R.id.levelQuestionsCount); 
       holder.lockedLevelContainer = (TextView) convertView.findViewById(R.id.lockedLevelContainer); 
       holder.start = (Button) convertView.findViewById(R.id.buttonLevel); 
       holder.levelLayout = (RelativeLayout) convertView.findViewById(R.id.levelLayout); 
       holder.levelLayoutInner = (LinearLayout) convertView.findViewById(R.id.levelLayoutInner); 
       holder.unlockedLevelContainer = (LinearLayout) convertView.findViewById(R.id.unlockedLevelContainer); 
       holder.locklevel = (ImageView) convertView.findViewById(R.id.locklevel); 

       convertView.setTag(holder); 

       holder.start.setOnClickListener(new View.OnClickListener() { 
        public void onClick(View v) { 
         D.sh("Clicked"); 

         Button start = (Button) v; 
         Level level = (Level) start.getTag(); 

         Intent dialogIntent = new Intent(MainActivity.this, LevelActivity.class); 
         dialogIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); 
         dialogIntent.putExtra("level", level.getLevel()); 
         MainActivity.this.startActivity(dialogIntent); 
        } 
       }); 

      } else { 
       holder = (ViewHolder) convertView.getTag(); 
      } 

      Level level = levelsList.get(position); 

      holder.levelLayoutInner.setBackgroundResource(R.drawable.bg_level_repeat); 

      if(level.getLevel() == 1) { 
       holder.levelLayout.setBackgroundResource(R.drawable.level1_button); 

       if(countSolved >= Level.L1_TO_UNLOCK){ 
        unlock(holder); 
       } else { 
        lock(holder, Level.L1_TO_UNLOCK); 
       } 

      } 

      if(level.getLevel() == 2) { 
       holder.levelLayout.setBackgroundResource(R.drawable.level2_button); 

       if(countSolved >= Level.L2_TO_UNLOCK){ 
        unlock(holder); 
       } else { 
        lock(holder, Level.L2_TO_UNLOCK); 
       } 

      } 

      if(level.getLevel() == 3) { 
       holder.levelLayout.setBackgroundResource(R.drawable.level3_button); 

       if(countSolved >= Level.L3_TO_UNLOCK){ 
        unlock(holder); 
       } else { 
        lock(holder, Level.L3_TO_UNLOCK); 
       } 

      } 

      if(level.getLevel() == 4) { 
       holder.levelLayout.setBackgroundResource(R.drawable.level4_button); 

       if(countSolved >= Level.L4_TO_UNLOCK){ 
        unlock(holder); 
       } else { 
        lock(holder, Level.L4_TO_UNLOCK); 
       } 
      } 

      if(level.getLevel() == 5) { 
       holder.levelLayout.setBackgroundResource(R.drawable.level5_button); 

       if(countSolved >= Level.L5_TO_UNLOCK){ 
        unlock(holder); 
       } else { 
        lock(holder, Level.L5_TO_UNLOCK); 
       } 

      } 


      holder.level.setText("Level "+level.getLevel()); 
      holder.levelQuestionsCount.setText(level.getSolved() + "/" + level.getTotal()); 

      holder.level.setTag(level); 
      holder.start.setTag(level); 
      return convertView; 

     } 
    }

njzk2, я использовал вашу идею.

for (int i=1;i<=5;i++) { 
       if(level.getLevel() == i) { 

        int resID = getResources().getIdentifier("level" + i + "_button" , "drawable", getPackageName()); 
        holder.levelLayout.setBackgroundResource(resID); 

        if(countSolved >= level.getToUnlock()){ 
         unlock(holder); 
        } else { 
         lock(holder, level.getToUnlock()); 
        } 

       } 
      }
