Description

This application claims priority to Chinese Patent Application No. 202210886321.0, filed with the China National Intellectual Property Administration on July 26, 2022 and entitled "FOLDABLE ELECTRONIC DEVICE AND DISPLAY METHOD FOR FOLDABLE SCREEN". TECHNICAL FIELD Embodiments of this application relate to the field of terminal technologies, and in particular, to a foldable electronic device and a display method for a foldable screen. BACKGROUND A foldable screen of an electronic device can meet a large screen requirement of a user in an unfolded state, and can also reduce a size in a folded state to meet a portable requirement. Therefore, the foldable screen is widely used. However, when a form of the foldable screen of the electronic device changes (for example, switching from the unfolded state to the folded state or switching from the folded state to the unfolded state), how to better implement adaptive display of screen content of the electronic device is a problem that a person skilled in the art has been studying. EP 3 958 117 A1 discloses a method for user interface layout in foldable or varying screen states. It describes detecting the device posture (landscape/portrait or single/large screen) and adjusting the user interface dimensions accordingly, and covers the concept of adapting interface elements to avoid blank areas upon transitions. SUMMARY This application provides a foldable electronic device and a display method for a foldable screen, to avoid a phenomenon of a large font and a large image, and effectively reduce a phenomenon that a page information amount in an unfolded state of the electronic device is less than that in a folded state. This provides good user experience. According to a first aspect, this application provides a display method for a foldable screen. The method includes: An electronic device may obtain a first height and a first width that are of an interface element on a first interface and that are set in an unfolded state, where the first height and the first width are determined based on a height and a width of the interface element in a folded state of the electronic device. The electronic device determines whether a ratio of the first height to a screen height is greater than a first threshold. If the ratio is greater than the first threshold, the height of the interface element is adjusted to a second height, where a ratio of the second height to the screen height is not greater than the first threshold. The electronic device obtains a second width based on the second height. The electronic device displays the first interface in the unfolded state, where the displayed first interface includes the interface element having the second height and the second width. It can be learned from the foregoing method that the electronic device may obtain, through calculation based on user experience, a threshold of a ratio of a height to the screen height, and design that the ratio of the second height of the interface element to the screen height is less than the threshold. In this way, a phenomenon that a large image and a large font size appear on the electronic device in the unfolded state can be effectively reduced, a use habit of the user can be complied with, and user experience is improved. In addition, a phenomenon that a content information amount in the unfolded state of the electronic device is less can be further reduced, to further improve user experience. In the foregoing method, the second height of the interface element may alternatively be designed adaptively, and a developer does not need to manually design a size and a layout of the interface element in the unfolded state in an application development stage, and this reduces workload of the developer. With reference to the first aspect, in some implementations, a ratio of the first width to the first height is equal to a ratio of the second width to the second height, or a difference between a ratio of the first width to the first height and a ratio of the second width to the second height is less than a first difference. In this way, the electronic device can ensure that an aspect ratio of the displayed interface element remains unchanged, and is more aesthetic. With reference to the first aspect, in some implementations, a control layout type of the first interface is a content grid type, a quantity of images accommodated in one row of the displayed first interface is greater than or equal to a quantity of images accommodated in one row of the set first interface, and a quantity of images accommodated in one column of the displayed first interface is greater than or equal to a quantity of images accommodated in one column of the displayed first interface. With reference to the first aspect, in some implementations, the interface element on the first interface includes a picture or a card, and an arrangement manner of the picture or the card is a grid type. With reference to the first aspect, in some implemen
