饼图的自定义AdapterView

Question

So I have created a custom AdapterView for a pie chart view that I'm using. I'm unsure of what I'm doing wrong but the pie chart is pretty choppy when I try to rotate it. I suspect too much drawing is going on as traceview shows a lot of calls to Canvas.nDrawDisplayList, which is not directly in my control.

I've placed a sample project on github to checkout ( https://github.com/saulpower/ExpandablePieChart ). It is a cool little library if I can get it working!

将所有内容移至Surfaceview并获得了相当不错的性能。
