用GsonFormat解析数组形式的json串

他首先要转化一下类型，那要怎么转呢那就要用到一个方法了TypeToken

List<DataDataBean> data = gson.fromJson(json, new TypeToken<List<DataDataBean>>() {}.getType());      //他要遍历取出他的值之后将他存到集和中去      for (DataDataBean dataDataBean:data){         List<DataDataBean.DataBean> dataBeen = dataDataBean.getData();         if(dataBeen!=null){            list.addAll(dataBeen);            setAdapter();            pullToRefreshList.onRefreshComplete();            }     }
