shared preference in android
<p>I am new in android development.</p>

<p>I've an activity in which I'm taking user name and password.and I'm passing those values to a web service which returns a key as a response.i have one toggle button in my activity. now if the user checks the toggle button that means he want to keep logged in  and the user should be redirected to next activity when he next time log-in.</p>

<p>If toggle button is checked I'm storing user name, password and key in shared preference.
 but I'm not getting how to retrieve those details next time(i.e when user next time log-in)</p>
