Check Android users "when the device is locked." Notification settings

Question

On Android L, I would like to show the user a notification on the lock screen only if the user’s settings are set to “show all notification content”, otherwise the content will be meaningless, and I just prefer not to show the notification at all.

Any idea how to check custom notification settings in the code?

Thank!
