        @Override
        public boolean onQueryTextSubmit(String query) {
            // TODO Auto-generated method stub

            Toast.makeText(getBaseContext(), query,
                    Toast.LENGTH_SHORT).show();

            return false;
        }

        @Override
        public boolean onQueryTextChange(String newText) {
            // TODO Auto-generated method stub
            TwoList.this.adapter1.getFilter().filter(newText);
            Toast.makeText(getBaseContext(), newText,
                    Toast.LENGTH_SHORT).show();
            return false;
        }
    });
}

It would seem that the `` with ID `search` is not in the `row` layout, either directly, or in an ``d layout. — Mike M., Apr 10 '17 at 07:01

You have not initialized your adapter1 anywhere in your code, thats why its throwing nullPointerException.

adapter1 = new ArrayAdapter(this, android.R.layout.simple_list_item_1, data1); rightList.setAdapter(adapter1); adapter1.notifyDataSetChanged(); – Dipak Apr 10 '17 at 07:05
Yea, you need to do it in your code as well. – Anmol317 Apr 10 '17 at 07:09
