Answer 1

I understand up to some point. In my expatiation i think your set by using adapter right. So the simple solution is once you get the new items for a grid. call the setadapter again. Then that will set the new items. Try it once.

Actually i have to comment out but i don't have that much points.

Answer 2

First you need to to add the received data into arraylist which you used to populate your grid view . You can add the received data into any position of arraylist as you need.

Then update the Arrayadapter using the following command

   adapter.notifyDataSetChanged();
