Creating Lists and Cards(RecyclerView + CardView)
Defining Shadows and Clipping Views(1.Material design introduces elevation (3D里面的Z轴的概念)for UI elements. 2.The elevation of a view, represented by the Z property, determines the visual appearance of its shadow: views with higher Z values cast larger, softer shadows. 3.Elevation is also useful to create animations where widgets temporarily rise above the view plane when performing some action.)
