Telerik图表选择行为不适用于android（Xamarin.Forms）中的RadPieChart

Question

我在xamarin.forms项目中使用Telerik饼图。选择行为在IOS中工作正常，但在Android SelectionChanged事件中未触发。

var selection = new ChartSelectionBehavior();
selection.SeriesSelectionMode = ChartSelectionMode.None;
selection.DataPointSelectionMode = ChartSelectionMode.Single;
selection.SelectionChanged += Selection_SelectionChanged;
pie.Behaviors.Add(selection);
