                ListView lv = getListView();
                ListAdapter adapter = new SimpleAdapter(Search_Equipments.this, myList,
                        R.layout.searchview, new String[]{"old_prop", "new_prop", "serial_no", "item_name","responsibility_center"}, new int[]{
                        R.id.txtsearch_old_prop, R.id.txtsearch_new_prop, R.id.txtsearch_serial_no, R.id.txtsearch_item_name, R.id.txtsearch_center});
                setListAdapter(adapter);

                InputMethodManager inputManager = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
                inputManager.hideSoftInputFromWindow(this.getCurrentFocus().getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS);
            }else {
                Toast.makeText(Search_Equipments.this,"No Records Available, Please enter valid value", Toast.LENGTH_LONG).show();
            }

 lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {

            HashMap<String,String> map =(HashMap<String,String>)lv.getItemAtPosition(position);
            //Cursor c = (Cursor) parent.getItemAtPosition(position);
            String prop = map.put(DBController.prop_no1);

            //String prop = String.valueOf(parent.getItemAtPosition(position - 1));
