对于布局的一部分,比如,你可以像这样的代码:
<Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
<CaptureElement Name="PreviewControl" Stretch="Uniform" />
<StackPanel HorizontalAlignment="Stretch" VerticalAlignment="Bottom"
Orientation="Vertical" Background="Transparent" Padding="10,10">
<TextBlock Text="Hold for Video, tap for photo" FontSize="15" Foreground="White"
HorizontalAlignment="Center" />
<Grid Margin="0,5,0,0" Background="#7FD3D3D3" Padding="10,10">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<TextBlock Text="Cancel" FontSize="15" Foreground="White" Margin="10,0,0,0" VerticalAlignment="Center" HorizontalAlignment="Left" />
<Border Height="50" Width="50" Grid.Column="1" VerticalAlignment="Center" HorizontalAlignment="Center"
CornerRadius="25" BorderBrush="White" BorderThickness="2" Tapped="Border_Tapped" Holding="Border_Holding">
<Ellipse Width="40" Height="40" Fill="White" />
</Border>
<SymbolIcon Grid.Column="2" VerticalAlignment="Center" HorizontalAlignment="Right" Margin="0,0,10,0" Symbol="Camera" Foreground="White"
Tapped="SymbolIcon_Tapped" />
</Grid>
</StackPanel>
</Grid>
随着制作的照片中,使用快速的可能性?
对于拍摄照片和视频部分,你可以参考官方Basic camera app sample,代码然后集成到你的样品中的Border
的Tapped
和Holding
事件:
private async void Border_Tapped(object sender, TappedRoutedEventArgs e)
{
await TakePhotoAsync();
}
private async void Border_Holding(object sender, HoldingRoutedEventArgs e)
{
await StartRecordingAsync();
}
为了使相机的闪光灯,你可以设置:
_mediaCapture.VideoDeviceController.FlashControl.Enabled = true;
我不知道什么是相机符号,所以我假设你想要启用/禁用fl灰例如像这样:
private void SymbolIcon_Tapped(object sender, TappedRoutedEventArgs e)
{
_mediaCapture.VideoDeviceController.FlashControl.Enabled = !_mediaCapture.VideoDeviceController.FlashControl.Enabled;
}
我想你可能还需要自定义布局时,控制被窃听,或者当被记录和布局的旋转视频,等等...
您可以创建自定义控件,该控件具有用于预览的CaptureElement控件,并且可以使用MediaCapture API捕捉照片和其他与媒体相关的任务。 –
