Xamarin.Forms:将单击事件添加到<Grid>中的映射？

<Grid>
    <Grid.RowDefinitions>
        <RowDefinition Height="Auto" />
        <RowDefinition Height="Auto" />
    </Grid.RowDefinitions>
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="Auto" />
        <ColumnDefinition Width="Auto" />
    </Grid.ColumnDefinitions>
    <!-- 添加其他控件到网格中 -->
</Grid>

var grid = new Grid();
var tapGestureRecognizer = new TapGestureRecognizer();
tapGestureRecognizer.Tapped += (s, e) =>
{
    // 处理单击事件的逻辑
};
grid.GestureRecognizers.Add(tapGestureRecognizer);

tapGestureRecognizer.Tapped += (s, e) =>
{
    // 处理单击事件的逻辑
    // 例如，显示一个提示框或导航到另一个页面
};
