TestNavigation

This project demonstrates a fundamental navigation system based on fragments. In addition to shorcuts of the left menu, it supports a push-pop style flow.

Android Studio 2.1 is used and the minimum SDK of the project is 19 (Android 4.4).

How to add a top level fragment

Add a new fragment.

Let MainActivity implement OnFragmentInteractionListener of the fragment.

Add a menu item to activity_main_drawer.xml.

Add if statement for the menu item.

if (id == R.id.nav_new) {
  FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
  ft.replace(R.id.content_frame, new NewFragment());
  ft.commit();
}

How to add a sub fragment

Add a new fragment.

Let MainActivity implement OnFragmentInteractionListener of the fragment.

Add a "push" logic to a super fragment.

getFragmentManager().beginTransaction()
        .add(R.id.content_frame, new NewFragment(), "new")
        .addToBackStack(null)
        .commit();
