title: Android - Create a settings object similar to volume control
body: <p>As the title says, I was wondering if there is a way to add a way to create input in my Android application, by providing the user with a bar similar to the one used by Android system for adjusting the sound volume. A specific variable would change its value, according to the position of a "button" on the bar (sorry for my English). Any advice on that?</p>
