如何刷新我的列表视图适配器？

Question

我遇到了这个问题，如果我在片段之间切换就可以。但是当我退出其他活动时，它不刷新。

我对这个有点弱，如果可能的话，请注明里添加代码，谢谢y'll

@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 
    View view = inflater.inflate(R.layout.favorite_page, null); 

    lv = (ListView) view.findViewById(R.id.listview_favorite); 

    list = new ArrayList<>(); 

    adapter = new BaseAdapter() { 
     ... 
     } 

     @Override 
     public View getView(int position, View convertView, ViewGroup parent) { 
      TextView tv = new TextView(getActivity()); 
      ... 
      convertView = tv; 
      return convertView; 
     } 
    }; 
    lv.setAdapter(adapter); 

    List<FavoriteBean> favData = DataSupport.findAll(FavoriteBean.class); 
    InputStream inputStream = getResources().openRawResource(R.raw.a); 
    try { 
     JSONObject obj = new JSONObject(LoadFiles.getString(inputStream)); 
     JSONArray jarry = obj.getJSONArray("items"); 
     ... 
    } catch (JSONException e) { 
     e.printStackTrace(); 
    } 

} 
} 

Answer 1

尝试：

((BaseAdapter)lv.getAdapter()).notifyDatasetChanged(); 

Answer 2

使用adapter.notifyDataSetChanged（）;
