Question

我在StackBox内部有一个Image图标，它位于ListBox内部，我想使用翻译行为为其设置动画，以便它进行“反弹”。

        <EasingDoubleKeyFrame KeyTime="0:0:0.8" Value="0"/>
      </DoubleAnimationUsingKeyFrames>
    </Storyboard>
  </phone:PhoneApplicationPage.Resources>

  <!--LayoutRoot is the root grid where all page content is placed-->
  <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-->
    <StackPanel x:Name="TitlePanel" Grid.Row="0" Margin="12,17,0,28">
      <TextBlock x:Name="ApplicationTitle" Text="MY APPLICATION" Style="{StaticResource PhoneTextNormalStyle}"/>
      <TextBlock x:Name="PageTitle" Text="page name" Margin="9,-7,0,0" Style="{StaticResource PhoneTextTitle1Style}"/>
    </StackPanel>

    <!--ContentPanel - place additional content here-->
    <Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0">
      <StackPanel>
        <ListBox>
          <Image x:Name="image" Source="Common/Main/res/drawable/smiley.png" Width="96" RenderTransformOrigin="0.5,0.5" Margin="180,0">
            <Image.RenderTransform>
            <CompositeTransform/>
            </Image.RenderTransform>
          </Image>
        </ListBox>
      </StackPanel>
    </Grid>
  </Grid>
</phone:PhoneApplicationPage>

但是当它向上移动时，图像的顶部会在其列表框父级边界内被剪切。

是否有一个属性可以调整，以便在动画时重叠边界？

谢谢！

您需要让您的父Grid更大。

尝试给StackPanel一个Margin 22。

使用工作示例进行更新

            </StackPanel>
        </Grid>
    </Grid>

如何在动画期间阻止控件被其ListBox父级边界剪切？
