在OSC的Windows Phone以及Android客户端上,个人消息中心里与别人的对话都是类似于手机短信那样的对话气泡。 在Windows Phone平台上我们是使用来自Coding4Fun小组提供的 ChatBubble控件
我们先来看看显示效果,如下图
现在看看具体的代码
<phone:PhoneApplicationPage.Resources> <DataTemplate x:Key="template_Normal"> <StackPanel> <c4f:ChatBubble ChatBubbleDirection="{Binding direction,Mode=OneTime}" Margin="{Binding border,Mode=OneTime}" Opacity="{Binding opactiy,Mode=OneTime}" Width="350"> <c4f:ChatBubble.Content> <Grid Width="350"> <Grid.RowDefinitions> <RowDefinition Height="Auto" /> <RowDefinition Height="Auto" /> </Grid.RowDefinitions> <TextBlock Text="{Binding content, Mode=OneTime}" Margin="0,0,31,12" HorizontalAlignment="Left" FontSize="22" Foreground="White" TextWrapping="Wrap" /> <TextBlock Text="{Binding time,Mode=OneTime}" Grid.Row="1" HorizontalAlignment="Right" FontSize="18" Margin="0,0,31,0" Foreground="White" TextWrapping="Wrap" /> </Grid> </c4f:ChatBubble.Content> </c4f:ChatBubble> </StackPanel> </DataTemplate> </phone:PhoneApplicationPage.Resources> <!--LayoutRoot 是包含所有页面内容的根网格--> <Grid x:Name="LayoutRoot" Background="Transparent"> <Grid.RowDefinitions> <RowDefinition Height="Auto"/> <RowDefinition Height="*"/> </Grid.RowDefinitions> <Canvas Margin="0,0,0,120"> <Image Source="/Resource/Top/WordsTop.jpg" Width="480" Height="120" Canvas.Top="0" /> <Rectangle Width="480" Height="65" Fill="Black" Opacity="0.7" Canvas.Top="55"/> <TextBlock x:Name="lblTitle" Text="" FontSize="40" Canvas.Left="10" Canvas.Top="60" Foreground="{StaticResource TitleBrush}"/> </Canvas> <!--ContentPanel - 在此处放置其他内容--> <ListBox Name="list_Words" Height="646" Grid.Row="1" VerticalAlignment="Top" ItemTemplate="{StaticResource template_Normal}"> <ListBox.ItemsPanel> <ItemsPanelTemplate> <VirtualizingStackPanel CacheMode="BitmapCache"/> </ItemsPanelTemplate> </ListBox.ItemsPanel> </ListBox> </Grid>
这里尤其注意到ChatBubbleDirection这个属性,这就是那个小箭头的指向。如果指错了可是被人笑话的 :D
