Question

我收到以下警告：

[WARN]（MvxBind）无法创建用于绑定的目标绑定 MvxValueConverterValueCombiner组合器操作的TextColor

绑定代码：

<TextView 
            android:id="@+id/text_view_header"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginLeft="4dp"
            style="@style/text_group_header"
            app:MvxBind="Text DisplayHeader; TextColor AppointmentFeedHeaderGroupColor(StartTime)"
        />

AppointmentFeedHeaderGroupColorValueConverter.cs

public class AppointmentFeedHeaderGroupColorValueConverter: MvxValueConverter<DateTime, Color>
    {
        private static readonly IDateTimeService DateTimeService = Mvx.Resolve<IDateTimeService>();
        private static readonly Color HeaderGroupBlack = GetColor(Resource.Color.black);
        private static readonly Color HeaderGroupRedLight = GetColor(Resource.Color.red_light);

        protected override Color Convert(DateTime value, Type targetType, object parameter, CultureInfo culture)
        {
            if (value != DateTimeService.Now.Date)
            {
                return HeaderGroupRedLight;
            }

            return HeaderGroupBlack;
        }

        private static Color GetColor(int resourceColorId)
        {
            var context = Mvx.Resolve<IMvxAndroidCurrentTopActivity>().Activity;

            return new Color(ContextCompat.GetColor(context, resourceColorId));
        }
    }

我在文件LinkerPleaseInclude.cs中添加了以下代码。

public void Include(TextView text)
{
    text.AfterTextChanged += (sender, args) => text.Text = "" + text.Text;
    text.Hint = "" + text.Hint;

    text.SetTextColor(Color.Black);
    var tc = text.TextColors;
    text.SetTextColor(tc);
}

它没有帮助

绑定MvvmCross TextColor不适用于Android
