[英]SharedPreferences in Android
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 . 我已经使用SharedPreferences在Main Activity中保存了一些细节。现在我想在其他活动中获取细节,但是我无法获取它们。
Code to save 保存代码
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();
}
Code to get 获取代码
SharedPreferences prefs = getPreferences(MODE_PRIVATE);
String username = prefs.getString("username", null);
But this is not working for me . 但这对我没有用。 How could I get his? 我怎么能得到他?
May this help you: 可以帮助您:
Buddy Change these lines in your code to get : 好友在代码中更改以下几行即可 :
SharedPreferences prefs = getSharedPreferences("shared", MODE_PRIVATE);
String username = prefs.getString("username","");
得到的代码应该是
SharedPreferences prefs = getSharedPreferences("shared", MODE_PRIVATE);
