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.

Dependent claims

An animation effect display method, applied to an electronic device, wherein the method comprises:

determining, by a user interface (UI) thread of an application, and based on information about a first animation effect of a first control group that is set by the application, a duration of the first animation effect, a start time of the first animation effect, and description information about an end frame of the first animation effect, wherein the first control group comprises one or more controls, and an animation trigger event triggers display of the first animation effect;
after the determining, by the UI thread of the application, and based on information about the first animation effect of the first control group that is set by the application, the duration of the first animation effect, the start time of the first animation effect, and the description information about the end frame of the first animation effect, the method further comprises deregistering, by the UI thread, an animation callback of the first animation effect, wherein the animation callback triggers the UI thread to modify a property of the control in the first control group;
determining description information about a target frame of the first animation effect based on the start time of the first animation effect, the duration of the first animation effect, a time corresponding to the target frame, and the description information about the end frame of the first animation effect, when generating display data of the target frame;
and
generating, by a rendering thread of the application or a rendering process, the display data of the target frame based on the description information about the target frame.

2 more elements

An electronic device, wherein the electronic device comprises one or more processors and a memory, wherein

the memory is coupled to the one or more processors, the memory is configured to store computer program code, the computer program code comprises computer instructions, and the one or more processors invoke the computer instructions, to enable the electronic device to:
determine, by a user interface (UI) thread of an application that is running on the electronic device, and based on information about a first animation effect of a first control group that is set by the application, a duration of the first animation effect, a start time of the first animation effect, and description information about an end frame of the first animation effect, wherein the first control group comprises one or more controls, and an animation trigger event triggers display of the first animation effect;
after the determining, by the UI thread of the application, and based on information about the first animation effect of the first control group that is set by the application, the duration of the first animation effect, the start time of the first animation effect, and the description information about the end frame of the first animation effect, deregister, by the UI thread, an animation callback of the first animation effect, wherein the animation callback triggers the UI thread to modify a property of the control in the first control group;
determine description information about a target frame of the first animation effect based on the start time of the first animation effect, the duration of the first animation effect, a time corresponding to the target frame, and the description information about the end frame of the first animation effect, when generating display data of the target frame;
and
generate, by a rendering thread of the application or a rendering process, the display data of the target frame based on the description information about the target frame.

3 more elements

An electronic device, wherein the electronic device comprises one or more processors and a memory, wherein

the memory is coupled to the one or more processors, the memory is configured to store computer program code, the computer program code comprises computer instructions, and the one or more processors invoke the computer instructions, to enable the electronic device to:
determine, by a user interface (UI) thread of an application that is running on the electronic device, and based on information about a first animation effect of a first control group that is set by the application, a duration of the first animation effect, a start time of the first animation effect, and description information about an end frame of the first animation effect, wherein the first control group comprises one or more controls, and an animation trigger event triggers display of the first animation effect;
determine, by the UI thread, properties of controls in the end frame of the first animation effect based on the description information about the end frame of the first animation effect;
and
compare, by the UI thread, the properties of the controls in the end frame of the first animation effect with properties of controls shown before the first animation effect starts, to determine a second control group, wherein the second control group is controls whose properties change in the duration of the first animation effect, and the second control group comprises the first control group;
determine description information about a target frame of the first animation effect based on the start time of the first animation effect, the duration of the first animation effect, a time corresponding to the target frame, and the description information about the end frame of the first animation effect, when generating display data of the target frame;
and
generate, by a rendering thread of the application or a rendering process, the display data of the target frame based on the description information about the target frame,
wherein the first control group is configured to be displayed through the first animation effect, a control in the second control group but not in the first control group is configured to be displayed through a second animation effect, and the animation trigger event further is further configured to trigger display of the second animation effect.
