How can I store a shared preference without having a preferences screen etc

I just want to store username and password when a checkbox is clicked. I don't need a context menu and a preference screen. how can I have a simple method that store those values in my login class?

to store a string value(for example) in the application shared prefs, from any activity derived class:

SharedPreferences prefs = getSharedPreferences(PEFS_DESIRED_NAME, MODE_PRIVATE);
    prefs.edit().putString("password", mPasswordValue).commit();

to load it next time:

SharedPreferences prefs = getSharedPreferences(PEFS_DESIRED_NAME, MODE_PRIVATE);
mPasswordValue = prefs.getString("password", DEFAULT_VALUE_IF_NOT_EXISTS);

you don't have to use the preferences screen .

here's a sample code (should be run in an activity , service , or whatever context that you have ) :

reading:

SharedPreferences sharedPreferences=getSharedPreferences("settings",Context.MODE_PRIVATE);
String userName=sharedPreferences.getString("userName",null);
String password=sharedPreferences.getString("password",null);

writing:

Editor editor=getSharedPreferences("settings",Context.MODE_PRIVATE).edit();
editor.putString("userName",userName);
editor.putString("password",password);
editor.commit()

for the "settings" , i suggest using a unique constant string , like the activity's class name . of course you can use anything you wish ...
