Toggle Button

• A toggle button allows the user to change a setting between two states. 
• You can add a basic toggle button to your layout with the ToggleButton object. Android 4.0 (API level 14) introduces another kind of toggle button called a switch that provides a slider control, which you can add with a Switch object.
