以JSON格式的String形式的全局数据保存在SharedPreferences中吗？

Question

在Android中以JSON格式保存全局数据并在需要时通过SharedPreferences访问它是正确的吗？

Answer 1

I would extract it and save it as a string before using it in shared preferences. It is easier for the app to read the string rather than the JSON formatted response.

Therefore do something similar to this:

SharedPreferences pref = getApplicationContext().getSharedPreferences("MyPref", 0); // 0 - for private mode
Editor editor = pref.edit();

editor.putBoolean("key_name", true); // Storing boolean - true/false
editor.putString("key_name", "string value"); // Storing string
editor.putInt("key_name", "int value"); // Storing integer
editor.putFloat("key_name", "float value"); // Storing float
editor.putLong("key_name", "long value"); // Storing long

editor.commit(); // commit changes

As you can see in the above, there is no predefined sharedpreference for a JSON object or array. Hence it is easier to extract the data from the JSON repsonse to a string and pass on that string in the SharedPreference.

Hope this helps :)
