Android的Volley网络Get/Post请求包实例代码，,GET请求 ```jav

GET请求 ```java // 1.创建请求队列
RequestQueue volleyRequestQueue = Volley.newRequestQueue(this);

// 2.json get请求处理
JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(
Request.Method.GET, "your server url", null,
new Response.Listener<JSONObject>() {

        @Override          public void onResponse(JSONObject arg0) {              try {                  String strState = arg0.getString("state");                  if (strState != null                          &amp;&amp; strState.equalsIgnoreCase("success")) {                      System.out.println("request success!");                  } else {                      System.out.println("request failed!");                  }              } catch (Exception e) {                  System.out.println("request failed!");              }          }      }, new Response.ErrorListener() {          @Override          public void onErrorResponse(VolleyError arg0) {              System.out.println("request failed!");          }      }) {@Override  protected Response<JSONObject> parseNetworkResponse(          NetworkResponse arg0) {      try {          JSONObject jsonObject = new JSONObject(new String(                  arg0.data, "UTF-8"));          return Response.success(jsonObject,                  HttpHeaderParser.parseCacheHeaders(arg0));      } catch (UnsupportedEncodingException e) {          return Response.error(new ParseError(e));      } catch (Exception je) {          return Response.error(new ParseError(je));      }  }

};

// 3.请求对象放入请求队列
volleyRequestQueue.add(jsonObjectRequest);

 2. POST请求 ```java    try {          // 1.创建请求队列          RequestQueue volleyRequestQueue = Volley.newRequestQueue(this);          // 2.POST请求参数          JSONObject params = new JSONObject();          params.put("name", "zhangsan");          params.put("password", "123456");          // 3.json post请求处理          JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(                  Request.Method.POST, "your server url", params,                  new Response.Listener<JSONObject>() {                      @Override                      public void onResponse(JSONObject arg0) {                          try {                              String strState = arg0.getString("state");                              if (strState != null                                      &amp;&amp; strState.equalsIgnoreCase("success")) {                                  System.out.println("request success!");                              } else {                                  System.out.println("request failed!");                              }                          } catch (Exception e) {                              System.out.println("request failed!");                          }                      }                  }, new Response.ErrorListener() {                      @Override                      public void onErrorResponse(VolleyError arg0) {                          System.out.println("request failed!");                      }                  }) {              @Override              protected Response<JSONObject> parseNetworkResponse(                      NetworkResponse arg0) {                  try {                      JSONObject jsonObject = new JSONObject(new String(                              arg0.data, "UTF-8"));                      return Response.success(jsonObject,                              HttpHeaderParser.parseCacheHeaders(arg0));                  } catch (UnsupportedEncodingException e) {                      return Response.error(new ParseError(e));                  } catch (Exception je) {                      return Response.error(new ParseError(je));                  }              }          };          // 4.请求对象放入请求队列          volleyRequestQueue.add(jsonObjectRequest);      } catch (Exception e) {      }
