以前写过一个wp8的工程，说实话那会的代码很麻烦，写起来费劲，另外还没多少人下载，不过到windows 10 开始微软出了UWP架构以后一切都像以前的winform wpf一样好转起来，新建一个工程以后模板很简洁。
现在就开始介绍一下基本控件的使用，为新手写程序提供一个例子。7天酒店没有官方客户端，不过不妨碍拿他做例子。
由于以前代码使用到了json.net 为了减少代码修改，所以还是需要引入进来，但去官方网站下载的无法直接使用，说什么不适配，只要打开
然后呢搜索Json 其实我打开默认第二个就是
添加好之后呢
开始布局代码
在MainPage.xaml中写如下代码
<Page x:Class="_7inns.MainPage" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="using:_7inns" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d"> <Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}"> <Grid.Resources> <CollectionViewSource x:Name="itemcollectSource" IsSourceGrouped="true" ItemsPath="ItemContent" /> </Grid.Resources> <Image Source="Assets/2.png" Margin="42,23,0,0" HorizontalAlignment="Left" VerticalAlignment="Top" Height="109" Width="94" /> <TextBlock Margin="42,193,264,0" TextWrapping="Wrap" Text="城市" VerticalAlignment="Top" FontSize="20" FontWeight="Bold"/> <TextBlock Margin="42,252,264,0" TextWrapping="Wrap" Text="区域" VerticalAlignment="Top" FontSize="20" FontWeight="Bold"/> <Button x:Name="buttonCities" Content="" HorizontalAlignment="Stretch" Margin="104,194,3,0" VerticalAlignment="Top" Click="buttonCities_Click" BorderThickness="1" Height="33"/> <SemanticZoom x:Name="semanticZoomCities" Margin="0" ViewChangeCompleted="SemanticZoom_ViewChangeCompleted" Visibility="Collapsed" Canvas.ZIndex="5" Background="{ThemeResource ApplicationPageBackgroundThemeBrush}"> <SemanticZoom.ZoomedInView> <ListView x:Name="ListCities" ScrollViewer.IsHorizontalScrollChainingEnabled="False" ScrollViewer.IsVerticalScrollChainingEnabled="False" ItemClick="ListCities_ItemClick" SelectionChanged="ListCities_SelectionChanged"> <ListView.GroupStyle> <GroupStyle> <GroupStyle.HeaderTemplate> <DataTemplate> <Border Background="#FFECAE0A" Height="60" Width="60"> <TextBlock Text="{Binding Key}" FontSize="50" Foreground="{ThemeResource ApplicationForegroundThemeBrush}"></TextBlock> </Border> </DataTemplate> </GroupStyle.HeaderTemplate> </GroupStyle> </ListView.GroupStyle> <ListView.ItemTemplate> <DataTemplate> <StackPanel> <TextBlock Text="{Binding name}" Height="40" FontSize="30"></TextBlock> </StackPanel> </DataTemplate> </ListView.ItemTemplate> </ListView> </SemanticZoom.ZoomedInView> <SemanticZoom.ZoomedOutView> <GridView x:Name="GridCitiesFirstName" ScrollViewer.IsHorizontalScrollChainingEnabled="False" ScrollViewer.IsVerticalScrollChainingEnabled="False" Margin="0,100" HorizontalAlignment="Center" VerticalAlignment="Center"> <GridView.ItemTemplate> <DataTemplate> <Border Height="60"> <TextBlock Text="{Binding Group.Key}" FontSize="24"></TextBlock> </Border> </DataTemplate> </GridView.ItemTemplate> <GridView.ItemsPanel> <ItemsPanelTemplate> <WrapGrid ItemWidth="60" ItemHeight="60" VerticalChildrenAlignment="Center" Orientation="Horizontal" HorizontalAlignment="Center" VerticalAlignment="Center" /> </ItemsPanelTemplate> </GridView.ItemsPanel> <GridView.ItemContainerStyle> <Style TargetType="GridViewItem"> <Setter Property="BorderBrush" Value="Gray" /> <Setter Property="Background" Value="#FFECAE0A" /> <Setter Property="BorderThickness" Value="3" /> <Setter Property="HorizontalContentAlignment" Value="Center" /> <Setter Property="VerticalContentAlignment" Value="Center" /> </Style> </GridView.ItemContainerStyle> </GridView> </SemanticZoom.ZoomedOutView> </SemanticZoom> <ComboBox x:Name="comboBoxDistricts" Margin="107,251,0,0" VerticalAlignment="Top" BorderThickness="1" SelectionChanged="comboBoxDistricts_SelectionChanged" Width="251"/> <TextBlock Margin="42,368,264,0" TextWrapping="Wrap" Text="关键字" VerticalAlignment="Top" FontSize="20" FontWeight="Bold"/> <TextBlock Margin="42,442,264,0" TextWrapping="Wrap" Text="入住时间" VerticalAlignment="Top" FontSize="20" FontWeight="Bold"/> <Button x:Name="search" Content="搜索" HorizontalAlignment="Right" Margin="0,0,10,49" VerticalAlignment="Bottom" Click="search_Click" FontSize="20" FontWeight="Bold" BorderThickness="1" RenderTransformOrigin="0.925,0.455" Width="129"/> <DatePicker x:Name="inRoomDate" Margin="96,454,0,0" VerticalAlignment="Top" DateChanged="inRoomDate_DateChanged" BorderThickness="1" Width="255"/> <TextBox x:Name="keyword" Margin="104,358,1,0" TextWrapping="Wrap" VerticalAlignment="Top"/> </Grid> </Page>
恕当时没什么布局概念，基本就是手动布局，罗列控件。布局的事情以后再慢慢写，不过微软的教程或者其他书里面这块讲的很清楚，各种panel grid 布局。
这个里面基本就是一些textblock 跟textbox button 和一个SemanticZoom SemanticZoom的效果就是联系人菜单那个感觉，这里用来选择城市
先看一下选择前的
点一下字母 就会有
然后可以选个北京
后台呢就会对这个选择的city进行行政区查询
private async void ListCities_SelectionChanged(object sender, SelectionChangedEventArgs e) { Debug.WriteLine("ListCities_SelectionChanged"); if (e.AddedItems.Count == 1) { currentCityItem = (CityItem)e.AddedItems.First(); Debug.WriteLine(currentCityItem.name); buttonCities.Content = currentCityItem.name; } string di = await FindDistrict(currentCityItem.id); int total = di.Length; semanticZoomCities.Visibility = Visibility.Collapsed; if (total <= 6) return; JArray jobjectAllDistricts = JArray.Parse(di); comboBoxDistricts.PlaceholderText = ""; comboBoxDistricts.Items.Clear(); if (DItem != null) { DItem.Clear(); for (int i = 0; i < jobjectAllDistricts.Count; i++) { DItem.Add(new DistrictItem { id = (string)jobjectAllDistricts[i]["id"], name = (string)jobjectAllDistricts[i]["name"] }); //Debug.WriteLine((string)jobjectAllDistricts[i]["name"]); comboBoxDistricts.Items.Add((string)jobjectAllDistricts[i]["name"]); } } Debug.WriteLine("Total bytes returned: " + total); }
FindDistrict这个函数就需要用到http请求了
当时这么写的 可能是win10推荐的代码 不过能用
private async Task<string> FindDistrict(string id) { string url = @"http://m.7daysinn.cn/q/city/" + id + @"/districts"; HttpClientHandler handler = new HttpClientHandler(); handler.AllowAutoRedirect = false; HttpClient httpClient = new HttpClient(handler); // Limit the max buffer size for the response so we don‘t get overwhelmed httpClient.MaxResponseContentBufferSize = 256000; string result; try { result = await httpClient.GetStringAsync(url); return result; } catch (Exception) { } return ""; }
点击搜索按钮
就可以得到这个日子的酒店列表啦
private async void search_Click(object sender, RoutedEventArgs e) { try { string url = @"http://m.7daysinn.cn/q/inns?cityId=" + currentCityItem.id; if (currentDistrictItem != null && currentDistrictItem.id != "") { url += "&districtId="; url += currentDistrictItem.id; } if (keyword.Text != "") { url += "&keyword="; url += Uri.EscapeUriString(keyword.Text); } url += "&fromDate=" + inDate.Date.ToString("yy-MM-dd") + "&days=1&getQuota=true"; HttpClientHandler handler = new HttpClientHandler(); handler.AllowAutoRedirect = false; HttpClient httpClient = new HttpClient(handler); // Limit the max buffer size for the response so we don‘t get overwhelmed httpClient.MaxResponseContentBufferSize = 256000; ParameterObject po = new ParameterObject(); po.result = await httpClient.GetStringAsync(url); po.date = inDate; Frame.Navigate(typeof(InnStatus), po); } catch (Exception) { } }
Frame.Navigate(typeof(InnStatus), po);这句呢就是把数据传到第二个页面
第二个页面Innstatus 解析并且展示出来
protected override void OnNavigatedTo(NavigationEventArgs e) { innstatus = (ParameterObject)e.Parameter; try { List<InnItem> innItems = new List<InnItem>(); JObject jobjectAllInns = JObject.Parse(innstatus.result); JArray jaRooms = (JArray)jobjectAllInns["content"]; for (int i = 0; i < jaRooms.Count; i++) { innItems.Add(new InnItem { innId = (string)jaRooms[i]["innId"], name = (string)jaRooms[i]["name"], firstCharsOfPinyin = (string)jaRooms[i]["firstCharsOfPinyin"], cityId = (string)jaRooms[i]["cityId"], cityName = (string)jaRooms[i]["cityName"], districtId = (string)jaRooms[i]["districtId"], districtName = (string)jaRooms[i]["districtName"], address = (string)jaRooms[i]["address"], score = (string)jaRooms[i]["score"], orderWeight = (string)jaRooms[i]["orderWeight"], thumbnailPath = (string)jaRooms[i]["thumbnailPath"], lowestPrice = (string)jaRooms[i]["lowestPrice"], hasRoom = (string)jaRooms[i]["hasRoom"], hasWifi = (string)jaRooms[i]["hasWifi"], hasPark = (string)jaRooms[i]["hasPark"], canUseCashCoupon = (string)jaRooms[i]["canUseCashCoupon"], brandId = (string)jaRooms[i]["brandId"], //currentActivities = (string)jaRooms[i]["currentActivities"], }); } this.inncollectSource.Source = innItems; ContentInnsList.ItemsSource = inncollectSource.View; } catch (Exception) { } }
效果如下
第二个页面的xaml代码就这么写的
一个数据模板
<Page x:Class="_7inns.InnStatus" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="using:_7inns" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d" Background="{ThemeResource ApplicationPageBackgroundThemeBrush}"> <Grid x:Name="LayoutRoot"> <Grid.ChildrenTransitions> <TransitionCollection> <EntranceThemeTransition/> </TransitionCollection> </Grid.ChildrenTransitions> <Grid.RowDefinitions> <RowDefinition Height="Auto"/> <RowDefinition Height="*"/> </Grid.RowDefinitions> <!-- TitlePanel --> <StackPanel Grid.Row="0" Margin="0" Orientation="Horizontal"> <TextBlock Text="酒店状态" Style="{ThemeResource TitleTextBlockStyle}" Typography.Capitals="SmallCaps" Margin="0,15,0,16.5" RenderTransformOrigin="1.473,0.155" Width="300" TextAlignment="Center"/> </StackPanel> <!--TODO: Content should be placed within the following grid--> <Grid Grid.Row="1" x:Name="ContentRoom"> <Grid.Resources> <CollectionViewSource x:Name="inncollectSource" IsSourceGrouped="False" ItemsPath="" /> </Grid.Resources> <ListView x:Name="ContentInnsList" HorizontalAlignment="Left" Margin="0" VerticalAlignment="Top" IsItemClickEnabled="True" ItemClick="ContentInnsList_ItemClick"> <ListView.ItemTemplate> <DataTemplate> <StackPanel> <TextBlock Text="{Binding name}" Height="40" FontSize="30"></TextBlock> <TextBlock Text="{Binding address}" Height="30" FontSize="14" Foreground="#FFECAE0A"></TextBlock> </StackPanel> </DataTemplate> </ListView.ItemTemplate> </ListView> </Grid> </Grid> </Page>
好啦 要介绍的就这么多
工程我上传上来好了方便新手调试
