Question

我在使用两个非0小数的double上遇到问题。例如，如果我的两倍是15.00，就可以了，但是如果我的双重是15.55，我的应用就会崩溃。这是在我的真实手机（Galaxy s8 +-API 26）上发生的，在android studio中的所有虚拟设备上，它都能与各种双打（15.00和15.55）配合使用。有人可以帮忙吗？

我的代码：

DecimalFormat formatData = new DecimalFormat("#.##");    
Menu_ID.add(Long.parseLong(menu.getString("Menu_ID")));
Menu_name.add(menu.getString("Menu_name"));
Menu_price50.add(Double.valueOf(formatData.format(menu.getDouble("Price_50"))));

if(Category_ID == 1) {
    Menu_price100.add(Double.valueOf(formatData.format(menu.getDouble("Price_100"))));
}

Menu_image.add(menu.getString("Menu_image"));
