Android - Navigation drawer fragments

Question

I have implemented navigation drawer in my android app. but now I want to be able to change the layout using fragments when the user clicks any list item in the navigation b

Answer 1

After generate a Navigation Drawer Activity by File->New->Activity->Navigation Drawer Activity, here are 3 steps

First, go to app_bar_main.xml then

replace

by

Second, go to MainActivity -> onNavigationItemSelected then modify it like

public boolean onNavigationItemSelected(@NonNull MenuItem item) {
    int id = item.getItemId();
    Fragment fragment = null;
    if (id == R.id.nav_camera) {
        fragment = CameraFragment.newInstance();
    } else if (id == R.id.nav_gallery) {
        fragment = GalleryFragment.newInstance();
    } else if (id == R.id.nav_slideshow) {
        fragment = SlideShowFragment.newInstance();
    }

    FragmentManager fragmentManager = getSupportFragmentManager();
    fragmentManager.beginTransaction().replace(R.id.frame_content, fragment).commit();

    setTitle(item.getTitle());

    DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
    drawer.closeDrawer(GravityCompat.START);
    return true;
}

Finally, create Fragment class, example a Fragment

public class CameraFragment extends Fragment{

    public static CameraFragment newInstance() {
         Bundle args = new Bundle();
         CameraFragment fragment = new CameraFragment();
        fragment.setArguments(args);
        return fragment;
    }

    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container,
            @Nullable Bundle savedInstanceState) {
        View rootView = inflater.inflate(R.layout.fragment_camera, null, false);
        return rootView;
    }
}
