在列表视图中，Android中可以加载多少个列表项

Question

Normally in ListView are used in android,but how many items can totally load in list view ? Is it possible to load more than 10,000 items ?

Answer 1

ListView itself will keep only a handful of view items in memory - those that are displayed on screen and possibly a few scrap items that are waiting to get recycled. ListView is not the limiting factor.

What is a limiting factor is the Adapter that feeds the ListView . If your adapter implementation keeps all data items in memory (eg an ArrayAdapter ), then you're bound to hit a limit at some point. There are other adapters such as CursorAdapter s that load the data items on demand and don't keep everything in memory. They scale further.

Of course there's usability. ListView is practically unusable for browsing through a list of 10000 items. If you really have that much data to display, you have an user interface design problem.

Answer 2

Try to use ViewHolder and convertView in View getView(int position, View convertView, ViewGroup parent) . You can load more than 10,000 items with low memory usage.
