Android uses dialogfragment to implement iphone-style rounded corners dialog box

Android implements iphone-style dialogs, mainly with the help of the Shape,corner element approach.

The following Circular_corner_dialog.xml file defines a rounded rectangle. The corner element specifies the fillet radius of the rounded rectangle, while the gradient element specifies the direction of the color gradient and the starting color. Of course, you can also use shape to create a variety of other shapes, such as ellipses, lines, and loops, and set different visual styles.
