@Override

       try {
          JSONObject all = new JSONObject(response);
          List<cityBean.CityInfoBean> city = new Gson().fromJson(all.getString("city_info"), new TypeToken<ArrayList<cityBean.CityInfoBean>>() {
          }.getType());
          for (int i = 0; i < city.size(); i++) {
              mData.add(city.get(i).getCity());

          adapter = new MyAdapter(mData,MainActivity.this, R.layout.recyclerview_item);
          mRv_main.setAdapter(adapter);

在列表中查看数据，但给出了logcat

No adapter attached; skipping layout

Answer 1

我假设在OkHttp请求返回之前显示了这些消息。

在onCreate中尝试此操作。除非您确实需要显示不同类型的数据，否则不应重新分配适配器。

adapter = new MyAdapter(mData,MainActivity.this, R.layout.recyclerview_item);
mRv_main.setAdapter(adapter);

在okhttp响应中，您需要执行此操作以使用新数据刷新适配器

mData.clear();
for (int i = 0; i < city.size(); i++) {
    mData.add(city.get(i).getCity());
}
adapter.notifyDataSetChanged();
mSwipeRefreshLayout.setRefreshing(false);

没有适配器;跳过布局，但已设置适配器
