TextView中的匿名錯誤

我正在開發一個餐廳應用程序。在這裏，我使用購物車頁面來查看用戶選擇結賬的食品項目。購物車商品使用RecyclerView列出，該商品有+ & - 按鈕增加&在結賬前減少產品數量。我的問題在這裏。TextView中的匿名錯誤

讓我們考慮的項目，如如下：

        Result TextView 
ChocoBar Rs25  - 4 + =  100  // Expected Result 

Vennila  Rs30  - 1 + =  30

同時點擊「+」按鈕，在ChocoBar

        Result TextView 
ChocoBar Rs25  - 5 + =  100 (set as 125 within fraction of second it is changed to 100)  

Vennila  Rs30  - 1 + =  30

但如果我使用gettext，

resultTextView is nothing but in code I used as holder.cartPriceDum

resultTextview.getText（）。toString - >返回125作爲ChocoBar項目值。

GetText工作但setText不工作。 gettting messup。請幫助我，我花了更多時間來修復它。但我還沒有修復它。

mycode的情況如下：

holder.ivIncrease.setOnClickListener(new View.OnClickListener() { 

    public void onClick(View arg0) { 
     clicked = true; 

     cartPrice = Integer.parseInt(holder.cartPrice.getText().toString()); 
     InDeQuantity = Integer.parseInt(holder.cartCount.getText().toString()); 
     if (null != mListener) { 
      cartRes.get(position).CartCount = (bigInt + 1); 
      notifyItemChanged(position); 
      mListener.onListFragmentInteraction(holder.cartRess); 
     } 
     UpdateCart(arg0); 
    } 

    private void UpdateCart(View view) { 
     String pID = cartRes.get(position).product_id; 
     int cartPrice = Integer.parseInt(holder.cartPrice.getText().toString()); 
     int cartIndividualTotal = cartRes.get(position).subTotal; 

     int cartCount = cartRes.get(position).CartCount; 

     System.out.println("Restaurant" + " Check" + "Product ID " + pID + "Cart Price " + cartPrice + 

       " cartIndividual Total " + cartIndividualTotal + " CartCount " + cartCount); 

     CommonUtil.dbUtil.open(); 
     CommonUtil.dbUtil.updateaddToCart(pID, cartPrice, cartCount, cartIndividualTotal); 
     Total = CommonUtil.dbUtil.getMultiply(pID); 
     CommonUtil.dbUtil.updateNetAmount(pID, Total); 
     setCartPrice(pID, holder); 
     view.invalidate(); 

     /*--- Set all the updated value into the CartRes Class---*/ 

     System.out.println("Cart Details" + cartRes.get(position).product_id + " " + 
       cartRes.get(position).CartproductName + " " + cartRes.get(position).CartcategoryName + 
       " " + cartCount + " " + cartPrice + " " + Total); 

     CartRes cartBasket = new CartRes(cartRes.get(position).product_id, cartRes.get(position). 
       CartproductName, cartRes.get(position).CartcategoryName, 
       cartCount, cartPrice, Total); 
    } 
}); 

/*======================================= *** ==============================================*/ 

/*--- If Cart count is 1, then disable Decrement icon*/ 
if (InDeQuantity <= 1) { 
    holder.ivDecrease.setVisibility(View.INVISIBLE); 
} else { 
    holder.ivDecrease.setVisibility(View.VISIBLE); 
} 

/*==================================== Decreasing Cart ====================================*/ 

holder.ivDecrease.setOnClickListener(new View.OnClickListener() { 

    public void onClick(View arg0) { 
     clicked = true; 

     cartPrice = Integer.parseInt(holder.cartPrice.getText().toString()); 
     InDeQuantity = Integer.parseInt(holder.cartCount.getText().toString()); 
     if (null != mListener) { 
      if (InDeQuantity > 1) { 
       cartRes.get(position).CartCount = (bigInt - 1); 
       notifyItemChanged(position); 
       mListener.onListFragmentInteraction(holder.cartRess); 
      } else if (InDeQuantity <= 0) { 
       InDeQuantity = 1; 
      } 
     } 
     UpdateCart(arg0); 
    } 

    private void UpdateCart(View view) {

     Total = CommonUtil.dbUtil.getMultiply(pID); 

     CommonUtil.dbUtil.updateNetAmount(pID, Total); 
     setCartPrice(pID, holder); 

     view.invalidate();

       cartRes.get(position).CartproductName + " " + cartRes.get(position).CartcategoryName + 
       " " + cartCount + " " + cartPrice + " " + Total); 

     CartRes cartBasket = new CartRes(cartRes.get(position).product_id,

private void setCartPrice(String pID, ViewHolder holder) { 
    Cursor cursor = CommonUtil.dbUtil.getCartIndividualPrice(pID); 
    if (cursor != null && cursor.moveToFirst()) { 
     int cartIndividualTotal = Integer.parseInt(cursor.getString(cursor.getColumnIndex(DbHelper.CART_TOTAL))); 

     holder.cartPriceDum.setText(String.valueOf(cartIndividualTotal)); 

     Log.e("Restaurant", " ADapterCheck" + cartIndividualTotal + " " + holder.cartPriceDum.getText().toString()); 
    } 
}

你是無效的視圖。 setCartPrice(pID, holder); view.invalidate();

每當您使視圖無效時，視圖將開始重繪本身，包括子視圖。可能這就是爲什麼它重置爲默認值。

對不起，即使移除view.invalidate（）後結果也是一樣的。 –

try like this 



//set Listener 
holder.ivIncrease.setOnClickListener(new IncreaseListener(holder.cartPrice,holder.cartCount,mListner,holder.cartRess,position)); 

// Create listener like this 
class IncreaseListener implements View.OnClickListener 
{ 
TextView cartPrice; 
TextView cartCount; 
Listener mListener; 
TextView cartRess; 
int position; 
IncreaseListener(TextView cartPrice,TextView cartCount,Listener mListener,TextView cartRess, int position) 
{ 
this.cartPrice= cartPrice; 
this.cartCount = cartCount; 
this.cartRess = cartRess; 
this.position = position; 
this.mListener = mListener; 
} 
    public void onClick(View arg0) { 
     clicked = true; 

     int cartPrice = Integer.parseInt(cartPrice.getText().toString()); 
     int InDeQuantity = Integer.parseInt(cartCount.getText().toString()); 
     if (null != mListener) { 
      cartRes.get(position).CartCount = (bigInt + 1); 
      notifyItemChanged(position); 
      mListener.onListFragmentInteraction(cartRess); 
     } 
     UpdateCart(arg0); 

} 
private void UpdateCart(View view) { 
     String pID = cartRes.get(position).product_id; 
     int cartPrice = Integer.parseInt(cartPrice.getText().toString()); 
     int cartIndividualTotal = cartRes.get(position).subTotal; 

     int cartCount = cartRes.get(position).CartCount; 

     System.out.println("Restaurant" + " Check" + "Product ID " + pID + "Cart Price " + cartPrice + 

       " cartIndividual Total " + cartIndividualTotal + " CartCount " + cartCount); 

     CommonUtil.dbUtil.open(); 
     CommonUtil.dbUtil.updateaddToCart(pID, cartPrice, cartCount, cartIndividualTotal); 
     Total = CommonUtil.dbUtil.getMultiply(pID); 
     CommonUtil.dbUtil.updateNetAmount(pID, Total); 
     setCartPrice(pID, holder); 
     view.invalidate(); 

     /*--- Set all the updated value into the CartRes Class---*/ 

     System.out.println("Cart Details" + cartRes.get(position).product_id + " " + 
       cartRes.get(position).CartproductName + " " + cartRes.get(position).CartcategoryName + 
       " " + cartCount + " " + cartPrice + " " + Total); 

     CartRes cartBasket = new CartRes(cartRes.get(position).product_id, cartRes.get(position). 
       CartproductName, cartRes.get(position).CartcategoryName, 
       cartCount, cartPrice, Total); 
    } 
}

對不起，結果是一樣的。在使用您的代碼時沒有發現結果中的任何更改。 @Rohit Heera –
