A call transfer method, applied to a system comprising a main terminal device, a first auxiliary terminal device, wherein the first auxiliary terminal device is a tablet, a watch, a personal computer, a stereo, a vehicle-mounted terminal device or a large screen, and a second auxiliary terminal device, the main terminal device, the first auxiliary terminal device, and the second auxiliary terminal device are connected to a same local area network and log in with a same user account, and the method comprises: displaying (S401), by the first auxiliary terminal device, a first window, wherein the first window is used to display a contact and a call state of a current call, the first window is a displayed window corresponding to a case that the current call is in an answered state, and the first window is used to display a candidate device list in response to a user clicking a call transfer key, wherein the candidate device list displays the main terminal device and the second auxiliary terminal device as candidates; receiving, by the first auxiliary terminal device, a user's operation of choosing the main terminal device or the second auxiliary terminal device as a respective candidate from the candidate list displayed in the first window; and in response to the user's operation of choosing the main terminal device as the respective candidate, sending, by the first auxiliary terminal device, a first call transfer indication message to the main terminal device; and in response to the user's operation of choosing the second auxiliary terminal device as the respective candidate, sending, by the first auxiliary terminal device, a first call transfer indication message to the second auxiliary terminal device; wherein the first call transfer indication message is used to instruct to transfer the current call, wherein before the displaying (S401), by the first auxiliary terminal device, a first window, the method further comprises: displaying, by the first auxiliary terminal device, a second window, wherein the second window is a displayed window corresponding to a case that the current call is in an unanswered state, and the second window comprises an answer key and a hang-up key; and answering, by the first auxiliary terminal device, the current call, and updating the displayed window from the second window to the first window, in response to a user's operation on the answer key.
A terminal device, comprising a processor and a memory, wherein the memory is configured to store a code instruction, and the processor is configured to execute the code instruction, to perform the method according to claim 1.
A computer-readable storage medium, configured to store a computer program, wherein the computer program comprises an instruction used to perform the method according to claim 1.
A computer program product, comprising computer program code, wherein the computer program code, when run on a computer, causes the computer to perform the method according to claim 1.

Description

TECHNICAL FIELD This application relates to the field of terminal technologies, and in particular, to a call transfer method and a terminal device. BACKGROUND With the development of terminal technologies and the wide use of terminals, terminal devices can provide users with various services to satisfy users' daily requirements. When a terminal device provides a user with a call service, if it is inconvenient for the user to make a call on the terminal device, the user may transfer the foregoing call to another terminal device, so as to retain continuity of the call and satisfy user's call requirements. The foregoing terminal devices may be respectively referred to as a main terminal device and an auxiliary terminal device. However, in the prior art, scenarios applicable to a call transfer between a main terminal device and an auxiliary terminal device are undiversified and not flexible enough, resulting in low call efficiency and poor user experience. WO 2021/185244 A1 relates to a device interaction method and device. When it is determined that an electronic device is in a video call state, the electronic device may display a dialog box or a control. In response to an operation performed on the dialog box or the control, the electronic device may interact with another device in a same local area network, for example, switch a video call from the electronic device to a smart television, or perform projection on a smart television. SUMMARY The invention is set out in the appended claims. This application provides a call transfer method and a terminal device, so as to improve flexibility of a call transfer between a main terminal device and an auxiliary terminal device and improve call efficiency and user experience. According to a first aspect, a call transfer method is provided, which is applied to a system including a main terminal device, a first auxiliary terminal device, where the first auxiliary terminal device is a tablet, a watch, a personal computer, a stereo, a vehicle-mounted terminal device or a large screen, and a second auxiliary terminal device, the main terminal device, the first auxiliary terminal device and the second auxiliary terminal device are connected to a same local area network and log in with a same user account, and the method includes: displaying, by the first auxiliary terminal device, a first window, where the first window is used to display a contact and a call state of a current call, the first window is a displayed window corresponding to a case that the current call is in an answered state, and the first window is used to display a candidate device list in response to the user clicking a call transfer key, wherein the candidate device list displays the main terminal device, the first auxiliary terminal device and the second auxiliary terminal device as candidates; receiving, by the first auxiliary terminal device, a user's operation of choosing the main terminal device or the second auxiliary terminal device as a respective candidate from the candidate list displayed in the first window; and in response to the user's operation of choosing the main terminal device as the respective candidate, sending, by the first auxiliary terminal device, a first call transfer indication message to the main terminal device; and in response to the user's operation of choosing the second auxiliary terminal device as the respective candidate, sending, by the first auxiliary terminal device, a first call transfer indication message to the second auxiliary terminal device; where the first call transfer indication message is used to instruct to transfer the current call. In this application, when a call is answered on an auxiliary terminal device, a user may click a call transfer key on the auxiliary terminal device, so as to transfer the current call to the foregoing main terminal device to be answered, thereby improving flexibility of a call transfer between the main terminal device and the auxiliary terminal device and improving call efficiency and user experience. Before the displaying, by the first auxiliary terminal device, a first window, the method further includes: displaying, by the first auxiliary terminal device, a second window, where the second window is a displayed window corresponding to a case that the current call is in an unanswered state, and the second window includes an answer key and a hang-up key; and answering, by the first auxiliary terminal device, the current call, and updating the displayed window from the second window to the first window, in response to a user's operation on the answer key. According to a second aspect, a terminal device is provided. The terminal device includes: a processor, where the processor is coupled to a memory, and may be configured to execute an instruction in the memory, to implement the method according to any possible implementation of the first aspect. The terminal device further includes the memory. According to a third aspect, a com
