在Android应用程序在本地保存的Facebook登录信息 [英] Saving facebook login details locally in android app

问题描述

我正在开发Android应用程序，用户拥有Facebook的共享设施。我有用户为Facebook的登录信息，现在我所要做的是，这些登录信息应保存，直到应用程序不会被删除。

当我试图找到这个答案，我得到了一些答案，说明有关共享preferences。但我不清除它究竟是如何工作的。

下面就是我要做的，

  =用户名username.getText（）的toString（）。。PASSWORD = password.getText（）的toString（）;
 

，其中用户名和密码2的EditText领域。当用户首次进入Facebook的进入，我应该什么地方保存这些数据对我今后的参考，使他不必重新登录。

任何一个可以让我知道如何实现这一目标？

解决方案

  //保存您的信息
共享preferences设置= getShared preferences（my_file_name，0）;
共享preferences.Editor编辑= settings.edit（）;
editor.putString（用户名，username.getText（）的toString（））;
editor.putString（密码，password.getText（）的toString（））;
editor.commit（）;//获取您的信息
共享preferences设置= getShared preferences（my_file_name，0）;
字符串username = settings.getString（用户名，）;
字符串密码= settings.getString（密码，）;
 

一个文件中创建：

 数据/数据​​/ [your.package.path] / shared_ preFS / [your.package.path] _ preferences.xml
 

I am developing an Android app where the user has the facility of Facebook sharing. I have the login details of the user for the Facebook, now what I am trying to do is these login details should be saved until the application is not deleted.

When I tried to find the answer for this, I got some answers stating about shared preferences. But I am not cleared exactly how it works.

Here is what I am trying to do,

Username = username.getText().toString();

PassWord = password.getText().toString();

where username and password are 2 edittext fields. When the user enters for the first time into Facebook, I should save these data somewhere for my future reference so that he need not login again.

Can any one let me know how to achieve this?

解决方案

// Save your info
SharedPreferences settings = getSharedPreferences("my_file_name", 0);
SharedPreferences.Editor editor = settings.edit();
editor.putString("username", username.getText().toString());
editor.putString("password", password.getText().toString());
editor.commit();

// Obtain your info
SharedPreferences settings = getSharedPreferences("my_file_name", 0);
String username = settings.getString("username", "");
String password = settings.getString("password", "");

A file will be created in:

data/data/[your.package.path]/shared_prefs/[your.package.path]_preferences.xml
