<一个href=\"https://github.com/johnnylambada/WorldMap/commit/7b94ac1b9a1e1144e173b62e6f0805ee81e2e030\">This提交我世界地图的演示应用的显示你有必要的修改，以从的android.view.View 来的<一个href=\"http://developer.android.com/reference/android/view/SurfaceView.html\">android.view.SurfaceView与<一个href=\"http://developer.android.com/reference/android/view/SurfaceHolder.Callback.html\">android.view.SurfaceHolder.Callback.

This commit of my WorldMap demo app shows you the changes necessary to convert from an android.view.View to an android.view.SurfaceView with an android.view.SurfaceHolder.Callback.

它通过使用查看欺骗一点的 的onDraw（）从 SurfaceView DrawThread ，并通过调用查看的 > onSizeChanged（）从内部 SurfaceView 的 surfaceChanged 。它只是使差异较小，更容易理解。

It cheats a bit by using the View's onDraw() from within the SurfaceView's DrawThread and by calling the View's onSizeChanged() from within the SurfaceView's surfaceChanged. It just makes the diff smaller and easier to understand.
