我想将此数据保存在.json文件中。我怎样才能做到这一点？？这是我要创建的result 如果他们有其他方法请我引导我在卡片视图中的可扩展列表视图中进行操作。任何帮助将不胜感激

您可以简单地使用SharedPreferences。

保存：

SharedPreferences sp = getSharedPreferences("your_pref_key", Activity.MODE_PRIVATE);
SharedPreferences.Editor editor = sp.edit();
editor.putString("your_key", yourValue);
editor.commit();

供阅读：

SharedPreferences sp = getSharedPreferences("your_pref_key", Activity.MODE_PRIVATE);
 String yourJson = sp.getString("your_key","defaultValue");

如果要反序列化，请使用gson

Gson gson = new Gson();  
YourClass yourObject = gson.fromJson(yourJson, YourClass.class);
