I highly recommend you to use RecyclerView instead of ListView and use Retrofit to send request and get the response as json.Take a look at these documents For RecyclerView.

i dont know how to use recycleview could you slove mt=y problem using custom list view – abhi jaghari Sep 24 '15 at 07:07
@abhijaghari Did you look at the Document? It has a fully explanation of recyclerView. RecyclerView is easier than custom listView to learn and use. Please take a look at the Document i've posted above. But if you couldnt understand the concept i'll post some code for cusomt listView. – Armin Ghoreishi Sep 24 '15 at 21:05
