自分的Volleyの定番コード

CustomRequestクラスを作成して以下の文章でvolley使う。例文はPOSTを使用する場合です。

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

		postMap.put("uuid", uuId);

		RequestQueue requestQueue = Volley.newRequestQueue(this);
		CustomRequest jsObjRequest = new CustomRequest(Request.Method.POST, Constant.USER_ADD_URL, postMap,
				new Response.Listener<JSONObject>() {
					@Override
					public void onResponse(JSONObject response) {

						Log.v("初期ユーザー登録、JSON", response.toString());

						// ここでタイマー起動
						// ３秒カウント開始のスケジュール
						timer = new Timer();
						timer.schedule(new MyTimer(), Constant.TITLE_COUNT_SEC);

					}
				},
				new Response.ErrorListener() {
					@Override
					public void onErrorResponse(VolleyError error) {

						Log.v("初期ユーザー登録、VolleyErr", "" + error);

					}
				});
		requestQueue.add(jsObjRequest);

public class CustomRequest extends Request<JSONObject> {

	private Response.Listener<JSONObject> listener;
	private Map<String, String> params;

	public CustomRequest(String url, Map<String, String> params,
						 Response.Listener<JSONObject> reponseListener, Response.ErrorListener errorListener) {
		super(Request.Method.GET, url, errorListener);
		this.listener = reponseListener;
		this.params = params;
	}

	public CustomRequest(int method, String url, Map<String, String> params,
						 Response.Listener<JSONObject> reponseListener, Response.ErrorListener errorListener) {
		super(method, url, errorListener);
		this.listener = reponseListener;
		this.params = params;
	}

	protected Map<String, String> getParams()
			throws com.android.volley.AuthFailureError {
		return params;
	}

	;

	@Override
	protected Response<JSONObject> parseNetworkResponse(NetworkResponse response) {
		try {
			String jsonString = new String(response.data,
					HttpHeaderParser.parseCharset(response.headers));
			return Response.success(new JSONObject(jsonString),
					HttpHeaderParser.parseCacheHeaders(response));
		} catch (UnsupportedEncodingException e) {
			return Response.error(new ParseError(e));
		} catch (JSONException je) {
			return Response.error(new ParseError(je));
		}
	}

	@Override
	protected void deliverResponse(JSONObject response) {
		// TODO Auto-generated method stub
		listener.onResponse(response);
	}
}
