Switch between Fragments with onNavigationItemSelected in new Navigation Drawer Activity template (Android Studio 1.4 onward)

Question

IntelliJ has made changes to the Navigation Drawer template Activity in Android Studio with fewer lines of code in the Activity class. The new Activity class looks like this

Answer 1

another way is:

public boolean onNavigationItemSelected(MenuItem item) {
    // Handle navigation view item clicks here.
    Fragment fragment;
    int id = item.getItemId();

    if (id == R.id.nav_camera) {
        // Handle the camera action
        fragment = new BlankFragment();
        FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
        ft.replace(R.id.container_new, fragment);
        ft.commit();
    } else if (id == R.id.nav_gallery) {
        fragment = new HorizontalView();
        FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
        ft.replace(R.id.container_new,fragment);
        ft.commit();
    } else if (id == R.id.nav_slideshow) {
        fragment = new FragmentVerticleView();
        FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
        ft.replace(R.id.container_new,fragment);
        ft.commit();

    } else if (id == R.id.nav_manage) {

    } else if (id == R.id.nav_share) {

    } else if (id == R.id.nav_send) {

    }

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

And then you'll need to implemts all the fragments to your activity. In my case it's

MainActivity.java

    public class MainActivity extends AppCompatActivity
    implements BlankFragment.OnFragmentInteractionListener, HorizontalView.OnFragmentInteractionListener,FragmentVerticleView.OnFragmentInteractionListener,OnNavigationItemSelectedListener
     { 
    //coding stuff
    }

And to handle the Exception that is Thrown in fragment java file

    "must implement OnFragmentInteractionListener"

you simply add below method

      public void    onFragmentInteraction(Uri uri){
    //We can keep this empty
}

And there you go! All set
