The strongest ListView optimization solution in the history of AndroidIn android development, Listview is a very important component. It automatically displays the specific content in the form of a list based on the length of the data. You can freely define the layout of each column of listview, however, when the listview has a large amount of data to load, it will occupy a large amount of memory, affecting performance.The focus of this article is to
