A method and device for realizing efficient access to notes

Abstract

The invention discloses a method and a device for realizing the efficient access of a note. The method comprises the following steps: dividing a note view into a plurality of note packages from top to bottom, and numbering the note packages in sequence, and storing the note packages in a database; receiving a note reading instruction sent from a user; through a UI (User Interface) thread, obtaining the current position information of a visual view in the note view, and synchronizing the current position information of the visual view to a cache thread; through the cache thread, according to the current position information, judging whether the corresponding note package is positioned in the cache region of the cache thread or not, obtaining the corresponding note package from the cache region, synchronizing the corresponding note package to the UI thread, otherwise, loading the corresponding package from the database into the cache region, and synchronizing the corresponding package to the UI thread; and through the UI thread, sending the received note package to the corresponding position in the visual view to be displayed. Through the method and the device, the access performance of the note is greatly improved, and the whole access performance is not restricted by the length of note contents or the size of a cache.

Description

technical field [0001] The invention relates to a method and device for realizing efficient access to notes. Background technique [0002] The note-taking function on electronic products is similar to marking on textbooks when we are reading, and it is synchronized with the learning content. To implement the note-taking function on electronic products, the traditional method is to save the current screen full-screen notes as a picture. The disadvantage of this method is that if the learning content has multiple screens, the next full-screen picture will be loaded when the screen is turned. There will be a sense of disfluency (the degree of disfluency is related to the hardware and software configuration of electronic products). In order to avoid more unsmooth feeling, the traditional method may store the loaded pictures in the memory, which obviously has higher requirements on the memory of electronic products. In addition, even if there is a point of modification when sav...

Problems solved by technology

In order to avoid more unsmoothness, the traditional method may store the loaded pictures in the memory, which obviously has higher requirements on the memory of electronic products

In addition, even if there is a point modification when saving, only the entire screen image can be saved, which consumes a lot of resources and is not reasonable enough.
