Read the JSON file once into a container of some sort. When responding to a button click, read next item from container and add to listview's adapter.

I already suggested this in your question below, including the sort of container you might consider to hold the JSON data.

Are you a developer? :confused:

But creating, or using, a container (i.e., data structure) to hold data that you download from a JSON file has nothing to do with Android. If the code you've shown is entirely of your making, then you shouldn't be having trouble.

I modify my code above as following I storage the parsed ArrayList, make a global variable for counting the number of times that the button has been clicked. public class MainActivity extends ListActivity { ArrayList venuesList; Button btn; int clickCount; // ArrayList allResults; List shownResults = new ArrayList(); final String CLIENT_ID = "SVIBXYYXOEARXHDI4FWAHXGO5ZXOY204TCF1QJFXQLY5FPV4"; final String CLIENT_SECRET = "BAAJO1KXRWESGTJJGVON4W3WUFHAQDAJPLRIYJJ5OPHFQ5VI"; final String latitude = "30.435665153239377"; final String longtitude = "31.3280148"; ArrayAdapter myAdapter; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); new fourquare().execute(); btn=(Button) findViewById(R.id.button); btn.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { String name = venuesList.get(clickCount).getName(); String cat = venuesList.get(clickCount).getCategory(); String city = venuesList.get(clickCount).getCity(); shownResults.add(name + "," + "cat" + "" + city); clickCount++; myAdapter.notifyDataSetChanged(); new fourquare().execute(); } }); } what is wrong in my code

I don't know, you tell us. What's it (not) doing? What's is (not) supposed to do? Is an exception being thrown? I obviously can't know these things. I do know you don't need to call
notifyDataSetChanged()since neither the array nor the adapter are changing in theonClick()method."One man's wage rise is another man's price increase." - Harold Wilson
