1.直接删除：
List<LineShop> tlineprices = new ArrayList<>();
tlineprices.remove(0);
2.使用遍历删除（iterator）:
List<LineShop> tlineprices = new ArrayList<>();
Iterator<LineShop> it = tlineprices.iterator();
while (it.hasNext()) {
LineShop lineShop = (LineShop) it.next();
if(lineShop.getUid().equals(uid)){
it.remove();
}
}
