Downloading image from web takes too much of time in Listview

Question

Hi in my application i need to download some images and text from the web and need to display in listview. for that i'm using POJO class means initially storing all the images in to the POJO class and then display in listview

It is good for less images but while downloading more than 100+ plus images it taking too much of time to load,

can anybody suggest some good solution for this.

you first download image then show or while showing list download image? — Shayan Pourvatan, Jan 28 '14 at 05:05
@Shayanpourvatan right now i downloaded the image first and showing in listview but it taking more time,i need some alternate way to reduce the time — Eyes, Jan 28 '14 at 05:09
you can use AsyncTask class to do your job parallel, while showing list all image downloaded, then first time that you run maybe not see any image but in continue all image loaded. — Shayan Pourvatan, Jan 28 '14 at 05:11

You can use the following libraries which are able to do lazy loading :

All these libraries are lazy loading ready which means these libraries can reuses views in widgets like ListView and GridView.

Try to use AsyncTask() method.Since it is doing its process in background it may work quicker.

i'm doing that in AsyncTask() only – Eyes Jan 28 '14 at 05:10
@Eyes you use `AsyncTask` for internet connection but we say use `AsynkTask` in `getView()` method not in main class and before showing list – Shayan Pourvatan Jan 28 '14 at 05:13
