            Toast.makeText(this, result.text, Toast.LENGTH_LONG).show();
            //String[] ch=getResources().getString(result.text);//result.text;
            //adapter = new ArrayAdapter<String>(this,R.layout.mainlist,result.text);

with this short snippet of code it is hard to know what the problem might be,

possibly this will help http://developer.android.com/resources/tutorials/views/hello-listview.html

after setListAdapter(adapter); try adding adapter.notifyDataSetChanged() or alternatively try adapter.setNotifyOnChange(true) just after initializing the adapter this might solve your issue if it is what i think it is. else post more of your code

You can use **ExpandableListView**

enter image description here

1) extend ArrayAdapter with your custom class:

class MyAdapter extends ArrayAdapter<Result>

2) create xml for layout of each row, eg. row.xml and set it in constructor of your adapter:

    MyAdapter(Activity context, int resourceId, ArrayList<Result>
    mResults) {             
      super(context, R.layout.row, mResults);
 }

3) in getView method of your adapter fill apropriate field with your result.text
4) set list adapter to your custom adapter

   MyAdapter adapter = new MyAdapter(this, 0, mResults);
  setListAdapter(adapter);
