android - Choose query database or use ram to build listview -

i need build listview many items.each item info queries managerquery or sqlite.it has fields: title(string), description(string), path(string). waver between save info of list object or info while building each item. saving info list object increase ram , getting info while building each item makes app slow (my listview has large no. of items).

querying db every time build new item slow down list scrolling. getting data before hand better approach.
