我正在使用渲染器列出文本链接,当我点击它时会打开浏览器。我希望当我单击链接时它指示单击的链接并返回变量中的值。渲染器中的哪个事件可以在触发时检查?

public class CustomLabelRenderer : LabelRenderer
{
    protected override void OnElementChanged(ElementChangedEventArgs<Label> e)
    {
        base.OnElementChanged(e);

        SetHtmlText();
    }



    protected override void OnElementPropertyChanged(object sender, PropertyChangedEventArgs e)
    {
        base.OnElementPropertyChanged(sender, e);
        SetHtmlText();
    }

    private void SetHtmlText()
    {
        if (Control != null)
        {
            Control.SetText(GetSpannedHtml(), TextView.BufferType.Spannable);
            Control.MovementMethod = LinkMovementMethod.Instance; // Makes links clickable
        }
    }

    private ISpanned GetSpannedHtml()
    {
        var source = Element?.Text ?? "";
        var html = Build.VERSION.SdkInt >= BuildVersionCodes.N
            ? Html.FromHtml(source, FromHtmlOptions.ModeLegacy)
            : Html.FromHtml(source);
        return html;
    }
}
