查了一天的错误，竟然。。。。。谁能看出哪里错了！！！

private List<Dialog_forlist> jSON2List2(String jsonPath) throws JSONException {
        List<Dialog_forlist> list = new ArrayList<>();
        InputStream is = AssetManagerUtils.getData(jsonPath, ReleaseActivity.this);
        String str = StreamTools.readStream(is);


        JSONObject object = new JSONObject(str);
        JSONArray jsonArray = object.getJSONArray("city");
        JSONObject jsonObject = jsonArray.getJSONObject(0);
        JSONArray jsonArray1 = jsonObject.getJSONArray("tdistrict");
        for (int i = 0; i < jsonArray1.length(); i++) {
            Dialog_forlist dialog_forlist = new Dialog_forlist();
            List<String> list_city = new ArrayList<>();
            if (i == 0) {
                JSONObject jsonObject1 = jsonArray1.getJSONObject(i);
                dialog_forlist.setName(jsonObject1.getString("name"));
                list_city.add("不限");
                dialog_forlist.setList(list_city);
            } else {
                JSONObject jsonObject1 = jsonArray1.getJSONObject(i);
                dialog_forlist.setName(jsonObject1.getString("name"));
                JSONArray jsonArray2 = jsonObject1.getJSONArray("bussinessareaList");
                for (int j = 0; j < jsonArray2.length(); j++) {
                    JSONObject jsonObject2 = jsonArray2.getJSONObject(i);
                    list_city.add(jsonObject2.getString("name"));
                }
                dialog_forlist.setList(list_city);
            }
            list.add(dialog_forlist);
        }
        return list;
    }

这是一个很常犯的错误，如果不是当时记得了，那就很难再发现（看代码是很难发现）。

用了debug才发现错误的所在，竟然是将j写成了i！！！

for (int j = 0; j < jsonArray2.length(); j++) {
                    JSONObject jsonObject2 = jsonArray2.getJSONObject(i);
                    list_city.add(jsonObject2.getString("name"));
                }
