        // Hashmap for ListView
        ArrayList<HashMap<String, String>> contactList;


        public FindPeopleFragment(){}

        @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container,

            }

            Movie movie = new Movie();
            baid=movie.getGUID();

            View rootView = inflater.inflate(R.layout.fragment_find_people, container, false);

            WebServiceCaller webServiceCaller = new WebServiceCaller();
            String Result = webServiceCaller.mydespatchDettails(baid);

            try {
                JSONObject Jasonobject = new JSONObject(Result);
                JSONArray Jarray = Jasonobject.getJSONArray("PendingDespatch");

                for (int i = 0; i < Jarray.length(); i++) {
                    JSONObject json_data = Jarray.getJSONObject(i);

                    String id = json_data.getString(TAG_ID);
                    String name = json_data.getString(TAG_NAME);
                    String code = json_data.getString(TAG_Code);
                    String address = json_data.getString(TAG_ADDRESS);

                    HashMap<String, String> contact = new HashMap<String, String>();

                    // adding contact to contact list
                    contactList.add(contact);

                }
                ListView list = (ListView) rootView.findViewById(R.id.list);

                  final ListAdapter adapter = new SimpleAdapter(getActivity()
                        ,contactList,

                list.setAdapter(adapter);

                list.setOnItemClickListener(this);
                //list.setListAdapter(adapter);
                inputSearch = (EditText) rootView.findViewById(R.id.inputSearch);

                inputSearch.addTextChangedListener(new TextWatcher() {
                    @Override
                    public void beforeTextChanged(CharSequence cs, int start, int count, int after) {

                      System.out.println("Text ["+cs+"]");
                     FindPeopleFragment.this.adapter.getFilter().filter(cs); 

    //***This is problem i cannot access adapter here..i want to to search by code***  





                        // FindPeopleFragment.TAG_Code..getFilter().filter(cs);
                    }

                    @Override
                    public void onTextChanged(CharSequence s, int start, int before, int count) {

                    }

                    @Override
                    public void afterTextChanged(Editable s) {

                    }
                });

            } catch (JSONException e) {
                e.printStackTrace();
            }
            return rootView;
        }

How about changing this line:

FindPeopleFragment.this.adapter.getFilter().filter(cs); 

into:

adapter.getFilter().filter(cs);

or

How about using AutoCompleteTextview for your search feature.
