Prevent android Navigation Drawer from closing till a condition is met

Question

I have a NavigationDrawer having a list with many radio buttons.I want the user to have to select a list item before he can close the Drawer.
The drawer should not close till the item is selected.
Is there a clean way with which I can achieve this??

Answer 1

Set up the DrawerLayout lock mode setDrawerLockMode as follow:

 mDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_OPEN);

but you need to handle actionbar home up button.
