Fragment从Activity获取数据(Activity一次性获取数据，然后分别传给各个fragment)

在Activity里把所需要的数据拿到后，放进一个Bundle里，再传到每个Fragment里

      //data是从服务器里获取的总数据数组      JSONArray data = object.optJSONArray("data");for (int i = 0; i < data.length(); i++) {JSONObject jo = data.optJSONObject(i);FragmentManager manager = getFragmentManager();    FragmentTransaction transaction =  manager.beginTransaction();    Fragment fragment = fragmentsList.get(i);Bundle bundle = new Bundle();bundle.putString("data", jo.optJSONArray("child").toString());fragment.setArguments(bundle);transaction.commit();}

//在每个Fragment里拿到数据，转化成之前的数组，再进行调用JSONArray data;Bundle bundle = getArguments();try {data = new JSONArray(bundle.getString("data"));} catch (JSONException e) {e.printStackTrace();}
