相关代码如下：

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
