Tile view(平铺视图) (lv_tileview)
Overview(概述)
显示原文
The Tile view is a container object whose elements (called tiles) can be arranged in grid form. A user can navigate between the tiles by swiping. Any direction of swiping can be disabled on the tiles individually to not allow moving from one tile to another.
If the Tile view is screen sized, the user interface resembles what you may have seen on smartwatches.

如果Tileview是屏幕尺寸的,它将提供可能已经在智能手表上看到的用户界面。
