相关代码如下：

<pre name="code" class="java">task.getData(new LoadDataFromServer.DataCallback() {            @Override            public void onDataCallback(JSONObject data) {              try {                              int code = data.getInteger("1");//                int code = data.getInteger("code");                if(code == 1) {                    Toast.makeText(UserInfoActivity.this, "更新成功1...",Toast.LENGTH_SHORT).show();                } else if(code == 2) {                    Toast.makeText(UserInfoActivity.this, "更新成功2...",Toast.LENGTH_SHORT).show();                } else {                    Toast.makeText(UserInfoActivity.this, "更新失败！！！...",Toast.LENGTH_SHORT).show();                }              } catch (JSONException e) {                  Toast.makeText(UserInfoActivity.this, "数据解析错误...",Toast.LENGTH_SHORT).show();                  e.printStackTrace();              }            }//            @Override//            public void onDataCallback(String returnData) {//                String result = returnData;//                Log.e("------------UserInfoActivity:updateAvatarInServer:onDataCallback----","--------result="+result+"---------");////            }        });

错误原因：在这个回调接口中，参数data是键值形式，它的实际值是（“1”，“1“），而我却用int code = data.getIneger("code")即key="code"来查找其对应的数据，但是实际值中并没有key="code"的这个键。

代码修改：把code换成”1“即可。即换成data中真正存在的键才能找到对应的值。

感悟：出现bug，如果编程环境没问题，那就是程序本身的问题，多把设计的程序的逻辑关系理一理，就能找到问题所在了
