Abstract: Embodiments of this application provide an animation effect display method and an electronic device, and relate to the field of electronic technologies. According to the animation effect display method provided in an embodiment of this application, before an animation effect is displayed, a UI thread of an application, or a rendering thread of the application, or a rendering process determines controls whose properties change in duration of the animation effect, and determines properties of controls on an interface of each frame, and then the rendering thread of the application or the rendering process generates, based on the properties of the controls on the interface of each frame, a bitmap corresponding to the interface of the frame. Because the properties like sizes and locations of the controls on the interface of each frame are determined before the animation effect is displayed, the UI thread does not need to perform measurement, layout, and drawing and recording (recording) on the interface of each frame, so that display of the animation effect is not affected by UI thread blocking.

Abstract: This application discloses an audio stream switching method and apparatus. After a switching device receives a switching instruction, the switching device determines a synchronization relationship between a switch-in stream and a switch-out stream, determines a parameter value of a switching point of the switch-in stream based on the synchronization relationship and a timestamp of a packet in the switch-in stream, and determines a timestamp of a switching point of the switch-out stream based on the synchronization relationship and a timestamp of a packet in the switch-out stream, and/or the switching device switches a packet that is in the switch-out stream and whose parameter value is greater than the parameter value of the switching point of the switch-out stream to a packet that is in the switch-in stream and whose parameter value is greater than the parameter value of the switching point of the switch-in stream.

Abstract: A positioning tag replacement method and a positioning server to implement replacement between positioning tags, where the method includes obtaining, by a positioning server, a moving trajectory of a first positioning tag and a moving trajectory of a second positioning tag, where the first positioning tag corresponds to a first positioned object, and the second positioning tag has no corresponding positioned object, and setting, by the positioning server, the second positioning tag to correspond to the first positioned object when the positioning server determines that the moving trajectory of the first positioning tag and the moving trajectory of the second positioning tag meet a preset condition. The method features low costs, simple and convenient operations, and easy implementation, and avoids that in an operation process, a positioned object escapes being monitored in a positioning system.
