如何实现车轮部件像iPhone？ [英] How to implement wheel widget like in iPhone?

问题描述

我想实现一个时间设置轮部件像一个iPhone有（<一个href="http://developer.apple.com/library/ios/#documentation/userexperience/conceptual/mobilehig/art/ui_datetimepicker.jpg">http://developer.apple.com/library/ios/#documentation/userexperience/conceptual/mobilehig/art/ui_datetimepicker.jpg).

1. 我应该使用GlSurfaceView或者只是延长​​查看？
2. 我应该让它作为一个复合视图（它将包含若干意见），或在OnDraw中画上的所有印刷品吗？
3. 在情况下，我将不会延长GlSurfaceView，怎么办（平滑）动画？启动一个线程，并调用postInvalidate（）？

I would like to implement a time settings wheel widget like the one iPhone has (http://developer.apple.com/library/ios/#documentation/userexperience/conceptual/mobilehig/art/ui_datetimepicker.jpg).

1. Should I use GlSurfaceView or just extend View?
2. Should I make it as a compound View (it would consist of several Views) or draw everything on the Canvas in onDraw?
3. In case I won't extend GlSurfaceView, how to do (smooth) animations? Start a Thread and call postInvalidate()?
