公交座位预定管理
Bus seat reservation management
目前我从 URL-
中得到以下 XML 数据格式
<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>
我已经制作了公交车的布局图,我想在其中单击空座位并禁用可用座位 0( <IsAvailable>0</IsAvailable> )
我很困惑我应该如何制作下面的布局,然后用我得到的 XML 数据填充。
- 如何进行座位布局。
- 如何使用 XML 数据填充座位,点击后将转移到下一个 activity 以进行进一步处理。
- 根据可用情况启用禁用席位。
我能够在我的代码中从 XML 解析 data/values....我想要知道如何制作布局格式并适合那些 XML 特定座位的值。
使用Table布局进行设计。您可以使用此代码进行设计参考此 link
