recyclerviewのスピナーの位置を処理する方法

Question

私はlistViewで2つのビューを持ち、if (position == 0)はそれを防ぐために何度も何度も呼び出されていますか？

1： - スピナーは、この実装を動作していない更新のために、リスト

@Override 
public void onBindViewHolder(MyViewHolder holder, int position) { 

    int viewType = getItemViewType(position); 
    switch (viewType) { 
     case LAYOUT_ZERO_INDEX: 
       holder.materialDesignSpinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() { 
        @Override 
        public void onItemSelected(AdapterView<?> parent, View view, int position, long id) { 
         String item = parent.getItemAtPosition(position).toString(); 
         Toast.makeText(parent.getContext(), "" + position, Toast.LENGTH_LONG).show(); 

         if (position == 0) { 
          dataarry.clear(); 
          dataarry.add(0, 1000); 
          dataarry.add(1, 5000); 
          dataarry.add(2, 6000); 
          dataarry.add(3, 8000); 
          dataarry.add(4, 3500); 
          dataarry.add(5, 4000); 
          dataarry.add(6, 5500); 
          notifyDataSetChanged(); 
          setData(6, 8000, holder); 
          holder.mChart.invalidate(); 
         } 
        if (position == 1) { 
          dataarry.clear(); 
          dataarry.add(0, 5500); 
          dataarry.add(1, 4500); 
          dataarry.add(2, 5200); 
          dataarry.add(3, 7000); 
          dataarry.add(4, 7000); 
          dataarry.add(5, 6000); 
          dataarry.add(6, 7800); 
     //      mChart.getData().notifyDataChanged(); 
    //      mChart.notifyDataSetChanged(); 
      //      mChart.clear(); 
          notifyDataSetChanged(); 
          setData(6, 8000, holder); 
          holder.mChart.invalidate(); 
          // setData(6, 8000); 
         } 

        } 

        @Override 
        public void onNothingSelected(AdapterView<?> parent) { 

        } 
       }); 
       ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String> 
     (context, android.R.layout.simple_dropdown_item_1line, weeklist); 
       holder.materialDesignSpinner.setAdapter(arrayAdapter); 
       holder.mChart.setDrawBarShadow(false); 
       setData(6, 8000, holder); 


      if (position == 1) { 
       holder.year.setText("ahmad"); 
       holder.year.setText("Mon,Oct 2"); 
       holder.earning.setText("Rs 1200"); 
       holder.trips.setText("10 سفر"); 
      } 
      break; 

    }

@Override

        String item = parent.getItemAtPosition(position).toString();
