How do I improve the performance of a listview?

Question

When I use images from the internet in a Listview, my Listview scrolls very slowly.
But in some applications such as Twitter, Google+ and other applications (despite showing images from the internet) there is no problem with scrolling and it is very fast and smooth.

How do I improve the performance of a Listview with images?

Check out this one, list view performance optimization from Larse Vogella

You can also use endless list or lazy loading where you load only some part of data in listview & load other when user reaches bottom of list lazy loading OR Commonsware's adapter for endless loading

There are some ThumbRules which might help you in optimizing listview:

-> Reuse Views by using ConvertView, in

`getView(AdapterView<?> adapterView, View convertView, int position, long id)`

->. Use Lazy Loading for Loading images from web, see

-> Also use ViewHolders to improve inflation time.check link:
