無法將edittext值設置爲textview基於位置

Question

我有一個列表視圖中的編輯文本。每次來自listview的編輯文本值都更新到數據庫中。我有食譜數量（這是編輯文本值）和食譜價格也分貝。我得到這些價格並保存在setprice變量中。但現在我想按照列表視圖位置將這些值設置爲文本視圖。但我能夠設置multipled值到適當的位置將其設置爲它希望

 quantityt.addTextChangedListener(new TextWatcher() { 
     @Override 
     public void beforeTextChanged(CharSequence s, int start, 
       int count, int after) { 

     } 

     @Override 
     public void onTextChanged(CharSequence s, int start, 
       int before, int count) { 
      valueList[position] = s.toString(); 
      Log.e("", "-----value list of position----" 
        + valueList[position]); 
      quantityval = valueList[position]; 
      Log.e("", "quantityval-----" + quantityval); 
      int selectedid = getid.get(position); 
      Log.e("", "selectedid-----" + selectedid); 
      te=db.update(quantityval, selectedid); 
      Log.e("", "te----" + te); 
      int getprice = pricesarray.get(position); 
      setprice = getprice * te; 
      Log.e("", "---set price value---" + setprice); 
      int id = (int) list.getItemIdAtPosition(position); 
      lContact.setExt(setprice); 

      // Log.e("", "lcontact.getExt value---"+lContact.getExt()); 
      holder.setprice.setText(String.valueOf(setprice)); 



     } 

     @Override 
     public void afterTextChanged(Editable s) { 

     } 
    });

嘗試用下面的代碼：

quantityt.addTextChangedListener(new TextWatcher() { 
     @Override 
     public void beforeTextChanged(CharSequence s, int start, 
       int count, int after) { 

     } 

     @Override 
     public void onTextChanged(CharSequence s, int start, 
       int before, int count) { 

     } 

     @Override 
     public void afterTextChanged(Editable s) { 
valueList[position] = s.toString(); 
      Log.e("", "-----value list of position----" 
        + valueList[position]); 
      quantityval = valueList[position]; 
      Log.e("", "quantityval-----" + quantityval); 
      int selectedid = getid.get(position); 
      Log.e("", "selectedid-----" + selectedid); 
      te=db.update(quantityval, selectedid); 
      Log.e("", "te----" + te); 
      int getprice = pricesarray.get(position); 
      setprice = getprice * te; 
      Log.e("", "---set price value---" + setprice); 
      int id = (int) list.getItemIdAtPosition(position); 
      lContact.setExt(setprice); 

      // Log.e("", "lcontact.getExt value---"+lContact.getExt()); 
      holder.setprice.setText(String.valueOf(setprice)); 
     } 
    });
