Surfaceview in listview scrolling issue

Question

我有一个问题。我正在开发一个基于surfaceview的控件，我将其称为“图形”。在此控件中我绘制一条路径（想象一个正弦函数）。这个控件工作正常。现在我想要我的应用程序将能够显示此图形控件的多个实例。我正在考虑使用listview控件来包含它们。我实现了它，但是当我滚动它时我遇到了问题。看起来listview中的adiacent图项重叠了每个另外，因为它没有正确刷新。你怎么看待使用listview的解决方案？解决这个问题的任何解决方案或替代方案？提前感谢.Paolo

You should consider using just the View class for your control. SurfaceViews are for processor intensive rendering such as videos and 3D graphics, they are ideally fixed to a location or full screen and they run in their own thread which doesn't work well with the rest of the UI.
