2results about How to "Improve refresh efficiency" patented technology

The application relates to the technical field of Android development, and discloses a cross-row-column irregular list moving and sorting method and device based on RecyclerView, aiming to solve the problem that the existing method cannot maintain the integrity and stability of a grid layout, and the scheme mainly comprises the following steps: defining a list item data object for storing self position information, self span information and adjacent span information of adjacent list items; sequentially traversing data in an original data list, converting the data into list item data objects, and generating a regularly arranged list item data object set; when a moving and sorting instruction is received, calculating a data exchange scheme, reordering the list item data object set, and synchronously updating information of affected list item data objects; comparing the list item data object set before and after moving and sorting, calculating a data difference set, and driving a RecyclerView adapter to perform local UI refreshing. The application maintains the integrity and stability of the grid layout and is suitable for cross-row-column irregular lists.

A metadata management method for a solid-state drive (SSD) and an SSD are disclosed. The metadata management method includes the following steps: when a first metadata refresh condition is met, organizing the currently recorded metadata into a full data block and refreshing it to the storage medium; when a second metadata refresh condition is met, organizing the changed metadata into an incremental data block and refreshing it to the storage medium; and restoring the metadata from the storage medium to the controller based on the full data block and / or the incremental data block, wherein the full data block and the incremental data block each correspond to a metadata information block, and the corresponding metadata information blocks are refreshed to the storage medium together during refresh. Each metadata information block records the starting address of the full data block and the incremental data block in the storage medium, as well as the quantity and length of the metadata contained in the full data block or the incremental data block. This disclosure implements incremental refresh of metadata, thereby improving refresh efficiency.
