Xamarin 有没有办法模拟按钮的点击？

我正在使用此代码创建类似于按钮的东西：

 <Grid Grid.Column="0" ColumnSpacing="0" Margin="0,0,10,0">

    <Frame Grid.Column="0" CornerRadius="5" OutlineColor="Black">
      <Label  x:Name="faveIconLabel" Style="{StaticResource mediumIcon}" Margin="0,2,0,0" HorizontalOptions="Fill" FontFamily="FontAwesome" VerticalOptions="Center" VerticalTextAlignment="Center" />
    </Frame>

    <Frame Grid.Column="1" CornerRadius="5" OutlineColor="Black">
      <Label x:Name="hiddenIconLabel" Style="{StaticResource mediumIcon}" Margin="0,2,0,0" HorizontalOptions="Fill" FontFamily="FontAwesome" VerticalOptions="Center" VerticalTextAlignment="Center" />
    </Frame>

  </Grid>

是否有一种方法可以模拟单击事件，使其看起来像他们单击标签时实际按下的东西？

您可以将TapGestureRecognitor添加到几乎任何VisualElement，包括标签、图像等

faveIconLabel.GestureRecognizers.Add(new TapGestureRecognizer((view) => OnLabelClicked()));

如果不想使用自定义渲染器，一种简单的方法是更改

handleClick

中的背景色，然后在几毫秒后将其还原为原始颜色。比如说,

private void handleClick(object sender, EventArgs e) {
    var view = (View)sender;
    view.BackgroundColor = Color.FromHex("#DD000000");

    Device.StartTimer(
        TimeSpan.FromMilliseconds(100), 
        () => 
        {
            // Revert it back to the original color, whatever it may be.
            Device.BeginInvokeOnMainThread(() => 
            {
                view.BackgroundColor = Color.Transparent; 
            });

            return false; // return false to prevent the timer from calling again
        });
}
