Interface processing method, electronic device, and graphical user interface

An electronic device, comprising:

• a display screen, an input device, a processor, a memory, a communications interface, and a bus, wherein the processor, the memory, and the communications interface are connected and complete mutual communication by using the bus, wherein
• the input device is configured to receive an instruction entered by a user, and transmit the instruction entered by the user to the processor;
• the memory is configured to store executable program code, wherein the program code comprises a computer operation instruction;
• and
• the processor runs a program corresponding to the executable program code by reading the executable program code stored in the memory, so as to:
• display, on the display screen, a basic function interface that comprises a first-type application interface element, wherein the basic function interface is corresponding to a simple operating system, the simple operating system is used to implement a basic function application of the electronic device, and the first-type application interface element is used to enable the basic function application in the simple operating system;
• receive a first switching instruction for interface switching that is entered by the user, wherein the first switching instruction is used to switch the basic function interface to the system function interface;
• send the received first switching instruction to the server;
• when the communications interface establishes a connection to the server, and the server responds to the first switching instruction and sends the second-type application interface element of the complete operating system, receive a second-type application interface element that is of a complete operating system and that is sent by a server, wherein the complete operating system is used to implement the basic function application and an additional function application of the electronic device, and the second-type application interface element is used to enable the basic function application and the additional function application in the complete operating system;
• and
• display, on the display screen, a system function interface that comprises the second-type application interface element according to the second-type application interface element received by the electronic device, wherein the system function interface is corresponding to the complete operating system;
• wherein after the displaying a system function interface that comprises the second-type application interface element,
• the input device is configured to receive a second switching instruction for interface switching that is entered by the user, wherein the second switching instruction is used to switch the system function interface to the basic function interface;
• and
• the processor runs the program corresponding to the executable program code by reading the executable program code stored in the memory, so as to display the basic function interface that comprises the first-type application interface element according to the received second switching instruction.
