A GridViewis a ViewGroup that displays items in two-dimensional scrolling grid. The items in the grid come from the ListAdapter associated with this view.
甲GridView的是一个的ViewGroup，在二维网格滚动显示的项目。网格中的项目来自与此视图关联的 ListAdapter。
This is what you'd want to use (keep using). Because a GridView gets its data from a ListAdapter, the only data loaded in memory will be the one displayed on screen. GridViews, much like ListViews reuse and recycle their views for better performance.
这就是您想要使用的（继续使用）。由于 GridView 从 ListAdapter 获取其数据，因此加载到内存中的唯一数据将是屏幕上显示的数据。GridViews，很像 ListViews 重用和回收它们的视图以获得更好的性能。
Whereas a GridLayoutis a layout that places its children in a rectangular grid.
而GridLayout是一种将其子项放置在矩形网格中的布局。
It was introduced in API level 14, and was recently backported in the Support Library. Its main purpose is to solve alignment and performance problems in other layouts. Check out this tutorialif you want to learn more about GridLayout.
它是在 API 级别 14 中引入的，最近在支持库中被反向移植。它的主要目的是解决其他布局中的对齐和性能问题。如果您想了解有关 GridLayout 的更多信息，请查看本教程。
