如何在软键盘显示时保持页面 header 粘滞?
How to keep page header sticky when soft keyboard shows?
我的 UWP 应用程序中有一个非常简单的页面,其中包含 header 和几个文本框:
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<TextBlock Grid.Row="0" Text="Page Title!" />
<ScrollViewer Grid.Row="1" VerticalScrollMode="Auto">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<TextBox Grid.Row="0" Margin="20" />
<TextBox Grid.Row="1" Margin="20" />
<TextBox Grid.Row="2" Margin="20" />
<TextBox Grid.Row="3" Margin="20" />
<TextBox Grid.Row="4" Margin="20" />
</Grid>
</ScrollViewer>
</Grid>
在 Windows 10 移动版中,当底部文本框获得焦点并出现软键盘时,页面的全部内容向上滚动,我不希望这样。我希望 header 保持可见并且滚动查看器滚动到文本框以保持可见。
我怎样才能做到这一点?
提前致谢。
您可以使用 CommandBar
并将 TextBlock
添加到 CommandBar.Content
,然后 header 将在页面中保持可见。页面 xaml 代码应如下所示,
<Page.TopAppBar>
<CommandBar Background="Transparent" OverflowButtonVisibility="Collapsed">
<CommandBar.Content>
<TextBlock Text="Page Title!" Margin="20" />
</CommandBar.Content>
</CommandBar>
</Page.TopAppBar>
<Grid>
<ScrollViewer VerticalScrollMode="Auto">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<TextBox Grid.Row="0" Margin="20" />
<TextBox Grid.Row="1" Margin="20" />
<TextBox Grid.Row="2" Margin="20" />
<TextBox Grid.Row="3" Margin="20" />
<TextBox Grid.Row="4" Margin="20" />
</Grid>
</ScrollViewer>
