『壹』 JAVA語言編寫的網上訂餐系統購物車功能如何實現
用Vector 或者是HashMap去裝
<下面有部分代碼你去看吧>
packagecom.aptech.restrant.DAO;

this.conn=conn;

*/
publicListchangeToList(Mapcarts){
//將Set中元素轉換成數組，以便使用循環進行遍歷

//定義double變數total，用於存放購物車內餐品總價格

//循環遍歷購物車內餐品，並顯示各個餐品的餐品名稱，價格，數量

//從Map對象cart中取出第i個餐品，放入cartItem中
CartItemBeancartItem=(CartItemBean)carts

『貳』 Android 實現美團，餓了么購物車效果
對兩個按鈕的背復景進行改變button、button2的選中制和為選擇狀態.beijing1).drawable.setBackgroundResource(R，讓後再button1和button2的點擊事件中，分別為button1的選中和為選擇狀態;上面是改變按鈕背景的代碼可以做兩組圖片
『叄』 仿餓了么，百度，美團外賣，訂餐網站外賣系統源碼
現在都用微信啦，看看雲快賣訂餐系統

tableViewCell布局篇–為方便大家查看, 我會盡量貼出全部代碼

UI布局篇–Masonry
- (void)layoutSubviews
{
[super layoutSubviews];
[_foodImage mas_makeConstraints:^(MASConstraintMaker *make) {
make.top.equalTo(self.contentView.mas_top).with.offset(5.0);
make.left.equalTo(self.contentView.mas_left).with.offset(5.0);

_btnMinus.hidden = YES;
[_btnPlus setTitle:@"加" forState:UIControlStateNormal];
[_btnPlus addTarget:self action:@selector(clickPuls:) forControlEvents:UIControlEventTouchUpInside];
}
btn點擊方法–
- (void)clickPuls:(UIButton *)btn
{
self.numCount += 1;
self.block(self.numCount, YES);
[self showOrderNums:self.numCount];
}
- (void)clickMin:(UIButton *)btn
{
self.numCount -= 1;
self.block(self.numCount, NO);
[self showOrderNums:self.numCount];
}
VC篇– 這里給出cellForRowAtIndexPath中代碼
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
XTFoodCell *cell = [tableView :cellIdentifier forIndexPath:indexPath];
// Block 回調
__weak __typeof(&*cell) weakCell = cell;
cell.block = ^(NSInteger nCount, BOOL boo){
CGRect parentRect = [weakCell convertRect:weakCell.btnPlus.frame toView:self.view];
if (boo) {
// 這里是動畫開始的方法
[self JoinCartAnimationWithRect:parentRect];
}
else
{
}
};
return cell;
}

『伍』 開發，仿美團，餓了么外賣訂餐系統
一句話總結：羊毛出在羊身上！餐飲老闆們遲早會很痛苦的，只有做自己的點餐渠道才是出路！

半小時微信自助服務系統讓消費者感覺速度更快、更簡單，訂單更多、商回家經營更答省錢、營銷效率高等優點，已被各種類型商戶（如：西餐廳、火鍋店、外賣盒飯、便利店，水果店，麵包店、甜點店等等）使用。近日，半小時微信餐廳訂餐服務系統發布3.0最新版本，對此之前2.0版本中的功能進行整合， 3.0版本主要更新兩大功能，1：新增會員卡功能，為商家發放會員卡，同時消費者可通過消費進行積分，享受不同的活動內容，商家還可以發優惠券，讓消費者享受更多優惠。 2：改版系統前台操作界面，新版界面更注重消費者視覺，以及操作習慣體驗，下單模式多層次，多模塊，更好的服務消費者。
