Question

目前我在URL -

的 XML数据格式下面得到这个
<Seat> <ColumnNo>0</ColumnNo> <Deck>2</Deck> <Height>2</Height> <IsAvailable>1</IsAvailable> <RowNo>0</RowNo> <SeatLabel>E</SeatLabel> <Width>1</Width> </Seat> <Seat> <ColumnNo>1</ColumnNo> <Deck>1</Deck> <Height>2</Height> <IsAvailable>1</IsAvailable> <RowNo>0</RowNo> <SeatLabel>SL5</SeatLabel> <Width>1</Width> </Seat> <Seat> <ColumnNo>2</ColumnNo> <Deck>1</Deck> <Height>1</Height> <IsAvailable>1</IsAvailable> <RowNo>0</RowNo> <SeatLabel/> <Width>1</Width> </Seat> <Seat> <ColumnNo>3</ColumnNo> <Deck>1</Deck> <Height>2</Height> <IsAvailable>1</IsAvailable> <RowNo>0</RowNo> <SeatLabel>SL1</SeatLabel> <Width>1</Width> </Seat>

我已经制作了布局图像，我要点击空置座位并禁用可用的座位为0 ( <IsAvailable>0</IsAvailable> )

我很困惑，我应该如何制作以下版面，然后填充我得到的XML数据。

如何制作座位布局。

如何使用XML数据填充席位，点击后将转移到下一个活动以进行进一步处理。

启用根据其可用性禁用座位。

我能够在我的代码中解析XML中的数据/值....我想知道如何制作布局格式并使这些XML值适合特定的席位。

Answer 1

使用表格布局进行设计。您可以使用此代码进行设计参考此link

{
    "_id": ObjectId("572992d6fc8b7a5c613248f6"),
    "userId": "0001",
    "fname": "Ankur",
    "lname": "Vishnoi",
    "address1": "Palam",
    "city": "New Delhi",
    "state": "Delhi",
    "pin": 110077,
    "cart": [
        {
            "productId": 8,
            "cartQty": 1
        }, 
        {
            "productId": 2,
            "cartQty": 3
        },
   ]
}

我就是这样做的，它仍处于测试阶段，我正在努力改进它。用户可以动态分配行中的行数和席位数（参见文本数据）。

预测试代码可在Github
