More Information
Summary:The present application discloses an anti-flicker method and apparatus for an Android whiteboard, wherein the method includes: determining a drawing canvas, and locking a display screen of the Android whiteboard, wherein the display screen is used to display a canvas drawing result; acquiring relevant data of a floating window; creating a target canvas by cropping the drawing canvas based on the relevant data; unlocking the display screen, and executing a drawing function through the target canvas. Since the Android whiteboard uses the target canvas created based on the floating window outline for drawing, thus, when the Android whiteboard needs to display a writing trajectory crossing over other floating window controls covering the Android whiteboard interface, it does not show the writing trajectory, thereby avoiding the occurrence of jaggies.
