Follow below code:

private static final String TAG_RESULT = "predictions";
JSONObject json;


ArrayList names;
ArrayAdapter adapter;
String browserKey = "Google API key";
//------------------------AutoComplete code--------------  
  public void updateList(String place) {
        String input = "";

        try {
            input = "input=" + URLEncoder.encode(place, "utf-8");
        } catch (UnsupportedEncodingException e1) {
            e1.printStackTrace();
        }

        String output = "json";
        String parameter = input + "&types=geocode&sensor=true&key="                + browserKey;

        url = "https://maps.googleapis.com/maps/api/place/autocomplete/"                + output + "?" + parameter;

        JsonObjectRequest jsonObjReq = new JsonObjectRequest(Request.Method.GET, url,
                null, new Response.Listener() {

            @Override            public void onResponse(JSONObject response) {
                System.out.println("response"+response);
                try {

                    JSONArray ja = response.getJSONArray(TAG_RESULT);

                    for (int i = 0; i < ja.length(); i++) {
                        JSONObject c = ja.getJSONObject(i);
                        String description = c.getString("description");
                        System.out.println("description"+description);
                        names.add(description);
                    }

                    adapter = new ArrayAdapter(
                            getApplicationContext(),
                            android.R.layout.simple_list_item_1, names) {
                        @Override                        public View getView(int position,
                                            View convertView, ViewGroup parent) {
                            View view = super.getView(position,
                                    convertView, parent);
                            TextView text = (TextView) view
                                    .findViewById(android.R.id.text1);
                            text.setTextColor(Color.BLACK);
                            return view;
                        }
                    };
                    edittext_signup_city.setAdapter(adapter);
                    adapter.notifyDataSetChanged();
                } catch (Exception e) {
                }
            }
        }, new Response.ErrorListener() {
            @Override            public void onErrorResponse(VolleyError error) {
            }
        });
        AppController.getInstance().addToRequestQueue(jsonObjReq, "jreq");
    }
