Dev Tip: Share navigation drawer among activities
Navigation drawer is a very handy and convenient way of navigating around the activities of an application. The implementation requires a drawer layout, and a navigator view should be initially positioned by setting the gravity. However, you got many activities and you have to implement every activity with the navigation drawer, well it seems tough. Here's an easy way to share the navigation drawer with multiple activities. All you need is to create a activity subclass and implement the navigation drawer for once. Finally extend your activities from the base class implementation, you're done! Here I provide you a sample implementation, feel free to fork and use in your projects.
