Volley :

Application 中:

HttpTools.init(context);

//Http 方式:

get(RequestInfo requestInfo, final HttpCallback httpResult);

post(RequestInfo requestInfo, final HttpCallback httpResult);

//下载方式:

DownloadRequest download(String url, String target, final boolean isResume, final HttpCallback httpResult)

DownloadRequest download(RequestInfo requestInfo, String target, final boolean isResume, final HttpCallback httpResult)

//文件上传:

Map<String,Object> params = new HashMap<String, Object>();

params.put("file0", new File("/sdcard/a.jpg"));

params.put("file1", new File("/sdcard/a.jpg"));

params.put("file2", new File("/sdcard/a.jpg"));

params.put("name", "张三");

mHttpTools.upload(url, params, httpResult);

MultiPartRequest<String> upload(final String url, final Map<String, Object> params, final HttpCallback httpResult)

MultiPartRequest<String> upload(RequestInfo requestInfo, final HttpCallback httpResult)

ImageRequest 和 DownloadRequest 不启用Gzip，其他请求均默认开启Gzip

Volley集成能了图片库.更加方便使用.

//图片库

BitmapTools.init(context);

BitmapTools.stop();

//本地方法

Bitmap getBitmapFromRes(int resId);

Bitmap getBitmapFromAsset(String filePath);

Bitmap getBitmapFromContent(String imageUri);

Bitmap getBitmapFromFile(String path);

BitmapTools bitmapTools = new BitmapTools(mContext);

bitmapTools.display(view, uri);

bitmapTools.resume();

bitmapTools.pause();

配置类 BitmapDisplayConfig.java ;

bitmapTools.display(final View view, String uri, BitmapDisplayConfig displayConfig);

//数据库 DbTools模块

数据库模块集成了xUtils中DbUtils。

使用方法参考xUtils。

添加混淆配置：-keep class * extends java.lang.annotation.Annotation { *; }

RequestQueue mQueue = Volley.newRequestQueue(context);

//get 请求

StringRequest stringRequest = new StringRequest("http://www.baidu.com",      new Response.Listener
   
    () {          @Override          public void onResponse(String response) {              Log.d("TAG", response);          }      }, new Response.ErrorListener() {          @Override          public void onErrorResponse(VolleyError error) {              Log.e("TAG", error.getMessage(), error);          }      });

mQueue.add(stringRequest);

<uses-permission android:name="android.permission.INTERNET" />

//post 请求

StringRequest stringRequest = new StringRequest(Method.POST, url,  listener, errorListener);  StringRequest stringRequest = new StringRequest(Method.POST, url,  listener, errorListener) {      @Override      protected Map
   
     getParams() throws AuthFailureError {          Map
    
      map = new HashMap
     
      ();          map.put("params1", "value1");          map.put("params2", "value2");          return map;      }  };

//json 请求

JsonObjectRequest jsonObjectRequest = new JsonObjectRequest("http://m.weather.com.cn/data/101010100.html", null,      new Response.Listener
   
    () {          @Override          public void onResponse(JSONObject response) {              Log.d("TAG", response.toString());          }      }, new Response.ErrorListener() {          @Override          public void onErrorResponse(VolleyError error) {              Log.e("TAG", error.getMessage(), error);          }      }); mQueue.add(jsonObjectRequest);
