Android中的SharedPreferences [英] SharedPreferences in Android

问题描述

我已经使用SharedPreferences在Main Activity中保存了一些详细信息.现在，我想在其他活动中获取详细信息，但是我无法获取它们.

I have used SharedPreferences to save some details in the Main Activity .Now i want to get the details in some other activity but i am not able to get them .

要保存的代码

public void saveInformation(String username,String password) {
        SharedPreferences shared = getSharedPreferences("shared", MODE_PRIVATE);
        SharedPreferences.Editor editor = shared.edit();
        editor.putString("username", username);
        editor.putString("password", password);
        editor.commit();
    }

要获取的代码

SharedPreferences prefs = getPreferences(MODE_PRIVATE); 
String username = prefs.getString("username", null);

但这对我不起作用.我怎么能得到他?

But this is not working for me . How could I get his?

推荐答案

获取的代码应为

SharedPreferences prefs = getSharedPreferences("shared", MODE_PRIVATE);
