Windows Phone 7編程學習點滴二——裝置方向、系統主題和系統托盤

標籤：

1 有兩種方式可以改變裝置的方向:

(1) 將SupportedOrientation設定為“PortraitOrLandscape”讓作業系統為你實現。

(2) 是通過代碼實現: OrientationChanged 事件。

1 this.OrientationChanged += new EventHandler<OrientationChangedEventArgs>(MainPage_OrientationChanged);  

 1 void MainPage_OrientationChanged(object sender, OrientationChangedEventArgs e)   2 {   3             if ((e.Orientation == PageOrientation.LandscapeRight) || (e.Orientation == PageOrientation.LandscapeLeft))   4             {   5                 TitlePanel.Visibility = Visibility.Collapsed;   6             }   7             else if ((e.Orientation == PageOrientation.PortraitDown) || (e.Orientation == PageOrientation.PortraitUp))   8             {   9                 TitlePanel.Visibility = Visibility.Visible;  10             }  11         }  12 }  

2 系統主題

在Visual Studio中右擊此項目，選擇“Open In Expression Blend…” 或在View菜單中選擇“Open In Expression Blend…”。

在Blend的UI中有一個標籤叫“Device”，看起來像這樣：

<Grid x:Name="LayoutRoot" Background="Transparent">  <Grid.RowDefinitions>  <RowDefinition Height="Auto"/>  <RowDefinition Height="*"/>  </Grid.RowDefinitions>  <!--TitlePanel contains the name of the application and page title-->  <Rectangle Stroke="Black" Grid.RowSpan="2">  <Rectangle.Fill>  <LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0">  <GradientStop Color="{StaticResource PhoneBackgroundColor}" Offset="0"/>  <GradientStop Color="{StaticResource PhoneAccentColor}" Offset="1"/>  </LinearGradientBrush>  </Rectangle.Fill>  </Rectangle>  <!--TitlePanel contains the name of the application and page title-->  <StackPanel x:Name="TitlePanel" Grid.Row="0" Margin="12,17,0,28">  <TextBlock x:Name="ApplicationTitle" Text="BLANKENSOFT" Style="{StaticResource PhoneTextNormalStyle}" mce_Style="{StaticResource PhoneTextNormalStyle}"/>  <TextBlock x:Name="PageTitle" Text="system theming" Margin="9,-7,0,0" Style="{StaticResource PhoneTextTitle1Style}" mce_Style="{StaticResource PhoneTextTitle1Style}">  <TextBlock.Foreground>  <SolidColorBrush Color="{StaticResource PhoneAccentColor}"/>  </TextBlock.Foreground>  </TextBlock>  </StackPanel>  <!--ContentPanel - place additional content here-->  <Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0">  <TextBlock Height="601" TextWrapping="Wrap" HorizontalAlignment="Left" Margin="0,6,0,0" x:Name="textBlock1" Text="Lorem ipsum dolor sit amet, consectetur adipiscing elit.
