Embodiment Construction
[0025] The present invention will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for ease of description, the drawings only show a part but not all of the structure related to the present invention.
[0026] Before discussing the exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although the flowchart describes the steps as sequential processing, many of the steps can be implemented in parallel, concurrently, or simultaneously. In addition, the order of the steps can be rearranged. The processing may be terminated when its operation is completed, but may also have additional steps not included in the drawings. The processing may correspond to metho...

The embodiment of the invention discloses a method and a device of accelerating black-screen gesture processing, a storage medium and a mobile terminal. The method includes: acquiring a gesture type corresponding to a black-screen gesture event when the black-screen gesture event is detected; matching gesture complexity, which corresponds to a black-screen gesture, according to the gesture type; determining a data sampling strategy according to the gesture complexity, and reading gesture coordinates according to the data sampling strategy; and drawing a gesture trajectory, which corresponds to the black-screen gesture, through at least one drawing thread according to the read gesture coordinates, and displaying the gesture trajectory according to a set screen refreshing rate. According to the embodiment of the invention, different data sampling strategies are determined according to different gesture types to realize various gesture coordinate reading modes, the amount of read data of an application layer and the amount of data adopted in drawing the gesture trajectory are reduced, speed of black-screen gesture processing is increased, system response time is reduced, and system power consumption is reduced.
Description
Technical field [0001] The embodiments of the present invention relate to mobile terminal technology, and in particular to a method, device, storage medium and mobile terminal for accelerating the processing of black screen gestures. Background technique [0002] With the development of technology, various electronic devices with touch screens are widely used by people, such as smart phones, tablet computers, or handheld game consoles. The touch technology adopted by these devices provides people with convenient input methods and brings great convenience. [0003] The functions developed on the basis of touch screens are also increasing, and the black screen gesture is one of the representative and technologically futuristic ones. The so-called black screen gesture means that the user draws some specific patterns on the touch screen to realize the function of quickly opening an application without the need to turn on the screen. However, the black screen gesture has a large amoun...
