与多个活动共享导航抽屉

Question

I have a navigation drawer activity. Behind most of the menu items i have various fragment and I only replace the content layout with the fragment like this:

fragmentManager.beginTransaction().replace(R.id.content_menu, new InformationFragment()).commit();

So when I click on a menu item, the navigation drawer slides back to the left, while the content changes to whatever is in the fragment and I can keep using the navigation drawer.

But one of the menu items does require its own Activity, so instead of a transaction to a new fragment I do:

Intent intent  = new Intent(this, NewActivity.class);
startActivity(intent);

In this new activity I can add the same navigation drawer as I use in my first activity and this works, but I cant imagine that this is the best way to handle this situation.

Is it possible to have the navigation drawer "above" the activities so they can share it?

Answer 1

I recently implemented this on a project. My main inspiration for the implementation came from the Google I/O official app .

To summarize the main points:

• Create an AppNavigationView that holds all the logic for displaying navigation items, closing or opening the drawer and handling click events
• Create a BaseActivity that has a an AppNavigationView member
• Make sure that each activity that requires a navigation drawer extends the BaseActivity you just created
