But i need to knw one thing, if i use Array adapter before assigning the values of str[i] its displaying listview also if i set adapter after assigning values to Str[i] also dispalying listview . Why so ?
For an example this line :- str1[i]=jsonArray.getJSONObject(i).getJSONObject("FORM"). getJSONArray("FPROP") .getJSONObject(0).getString("FNAME"); } ArrayAdapter<String>adapter=new ArrayAdapter<String> (this,android.R.layout.simple_list_item_1,android.R.id.text1,str1); lv.setAdapter(adapter); } And my code is here , JSONArray jsonArray=jsonObj.getJSONArray("formlist"); int length = jsonArray.length(); String[] str1 =new String[length]; // ArrayAdapter<String>adapter=new ArrayAdapter<String> (this,android.R.layout.simple_list_item_1,android.R.id.text1,str1); // lv.setAdapter(adapter); // ArrayList<String> items = new ArrayList<String>(); for (int i = 0; i < length; i++) { str1[i]=jsonArray.getJSONObject(i).getJSONObject("FORM"). getJSONArray("FPROP") .getJSONObject(0).getString("FNAME"); } ArrayAdapter<String>adapter=new ArrayAdapter<String> (this,android.R.layout.simple_list_item_1,android.R.id.text1,str1); lv.setAdapter(adapter); } catch (JSONException e) { On Sun, Aug 5, 2012 at 12:55 AM, Meena Rengarajan <meenasoft...@gmail.com>wrote: > Yeah , exactly what you have said is right .
