如何绕过Android中的Intent Extras? [英] How to bypass intent extras in Android?

问题描述

我想知道是否有办法将所有额外功能传递给新意图.

I want to know if there is a way to pass all the extras to the new intent.

有可能吗?这是个好主意吗?

Is it possible? And is it a good idea?

原因是我想将登录状态另存为json字符串，并在Activity之间传递它.我不想用SQLite或任何东西存储数据.我可以绕过所有新的意图吗?

The reason is that I want to save the login state as a json string, and pass it in between Activities. I don't want to store data with SQLite or anything. Can I bypass all the intent extras to the new intent ?

推荐答案

请考虑共享首选项:

  // Declaration
   public static String KEY = "SESSION";

   public static void saveUserName(String username, Context context) {
        Editor editor = context
                .getSharedPreferences(KEY, Activity.MODE_PRIVATE).edit();
        editor.putString("username", username);
        editor.commit();
    }

    public static String getUserName(Context context) {
        SharedPreferences savedSession = context.getSharedPreferences(KEY,
                Activity.MODE_PRIVATE);
        return savedSession.getString("username", "");
    }

您可以将登录凭据存储为首选项，并在任何活动中都可以检索它们.

You can store the login credentials to preference and retrieve them as well in any of your activity.

SaveUsername("Your text to save", Your_activity.this);

并获取值

String mUserName = getUserName(YourActivity.this);

建议将所有首选项方法都放在utils类中，以保持代码井井有条.

It is recommended to have all your preference methods in your utils class to keep the code organized.
