抽屉，片段和活动

Question

I have some questions about designing applications with NavigationDrawer .

I create an application with NavigationDrawer composed of one Activity and some Fragment s. For example I have four Fragment s, and every Fragment has some actions.

Which is the correct way to implement that?

1. Adding all actions to my Activity ?
2. Create some other classes and call them from MainActivity with context/view?
3. Other?

Any information about these questions is really appreciated. I also need some example or resource explaining which is the correct way to implement this.

Anyone can help?

Check the google IO 2014 source code to get a good idea of the nav drawer implementation

All the navigation and fragment transactions should be done via the Main Activity or the activity holding the fragments. Any kind of fragment - fragment communication should be avoided. The developer docs shows a good example of how to handle fragment communication via Activity using interfaces
