Abstract: An index display method includes displaying an index interface including a first region and a second region. The first region is located at an edge of the index interface and surrounds the second region. The first region displays an index identifier, and the second region displays content corresponding to a selected index identifier. A quantity of index identifiers displayed in the first region can respond to an operation change of a user, and a size of the first region matches a quantity of displayed index identifiers. When the quantity of the index identifiers displayed in the first region is changed from a second quantity to a first quantity of a smaller quantity, the selected index identifier is displayed at a start location or an end location of the first region when an index identifier including the second quantity is displayed.

Abstract: This disclosure provides a method for displaying application icons. The method may be applied to an electronic device having an expansible screen. When the expansible screen is in a first state, a first group of application icons are displayed in a shortcut window region of the screen, and if the expansible screen changes from the first state to a second state, a second group of application icons are displayed in the shortcut window region of the screen. A quantity of the second group of application icons is greater than a quantity of the first group of application icons. The first state indicates a state in which the expansible screen is not expanded. The second state indicates a state in which the expansible screen is expanded. Corresponding electronic device and storage media are also described.

Abstract: A data reading circuit for reading data stored in a resistive random access memory includes a sense amplifier, a first switch, a second switch, a current trimming circuit, and a reference cell. The sense amplifier has a first input terminal coupled to a first terminal of the first switch and the data cell, and a second input terminal coupled to a first terminal of the second switch and the reference cell. A second terminal of the first switch is coupled to a second terminal of the second switch through the current trimming circuit. The current trimming circuit is configured to trim a current of the first input terminal of the sense amplifier, or trim a current of the second input terminal of the sense amplifier.

Abstract: A method, applied to an electronic device having a foldable screen that comprises a first sub-screen and a second sub-screen, the method comprises making a determination that a preset condition is met, wherein the preset condition comprises detecting, within a preset duration, a touch operation performed by a user on the electronic device and detecting, using a sensor with the preset condition, a change of an included angle between the first sub-screen and the second sub-screen, and performing, in response to the determination, a preset operation associated with the touch operation and the change of the included angle.

Abstract: An unlocking method and an electronic device relate to the field of terminal technologies.

Abstract: An interface display method is provided. The method includes: An electronic device displays an interface of a first application in a first display area of a display (501). The electronic device receives a first operation when the electronic device displays the interface of the first application (502). In response to the first operation, the electronic device displays a multi-task interface in the first display area (503), where the multi-task interface includes an application window of a currently running application. The electronic device receives a second operation performed on an application window of a second application in the application windows of the currently running applications (504). In response to the second operation, the electronic device displays the interface of the first application and an interface of the second application in different areas in the first display area (505).

Abstract: A screen control method implemented by an electronic device that includes a foldable first screen and a second screen includes detecting, by the electronic device, an operation on a function button, determining, by the electronic device, a physical form of the electronic device, and controlling, by the electronic device, the foldable first screen or the second screen based on the operation and the physical form of the electronic device.
