The reason is that you are initializing your Calender instance everytime. So, its taking the current date/time instance. So, better would be initialize in once and use it again. Declare it globally and initialize it in onCreate().

Calendar calendar = null;

protected void onCreate(Bundle savedInstanceState){

calendar = Calendar.getInstance();
...
}

now, use this calender instance in your onClick() event.
