Setting shadows on the controls will make the interface elements look better. Google provides us with a ready-made control CardView, which can be thought of as FrameLayout adding fillets and shadows on top of itself.

In this article, shadows are realized by setting the background for the control.

Create a new Drawable Resource File under res/drawable

Using layer-list layers means that multiple layers can be covered one layer at a time

Create a new gradient layer item as the background layer, mainly gradient,shape is used to define the shape, corners sets the angle, gradient defines the shape for the gradient fill, startColor start color, endColor end color, angle represents the direction angle. When angle=0, the gradient is from left to right. Then turn counterclockwise, from the bottom to the top when angle=90

Create a new layer, as the top layer, the principle of shadow realization is that the small display of the top layer reveals a part of the layer below. This requires setting the left, top, right and bottom properties of Item. The setting of these parameters is similar to setting margin, so you can have a shadow effect. Of course, for the effect, my parameters are a little exaggerated, only the shadows on the right and below are set. Solid sets the fill, and stroke sets the border, sets the color, and sets the width to see the border effect.

On the top layer, you can still add the change effect of touch, that is, when the finger touches the control, the background color of the control changes.

Use: android:background= "@ drawable/ your shadow xml file"
