背景                                                                                            

SharedPreferences我觉得是最容易上手的，以xml方式存储。

代码                                                                                            

public class share {    public static void saveInfo(Context context,String username,String password)    {        SharedPreferences sp = context.getSharedPreferences("config", context.MODE_PRIVATE);        Editor editor = sp.edit();        editor.putString("username", username);        editor.putString("password", password);        editor.commit();    }}

主要就是开启edit，然后写数据，然后commit。

SharedPreferences sp = getSharedPreferences("config", MODE_PRIVATE);        String username = sp.getString("username", "");        String password = sp.getString("password", "");        usernameText.setText(username);        passwordText.setText(password);

上面的是读数据。
