Android app: How to change fragments in Navigation Drawer

First of all I'm new to android developement and also to java.

I created a new project with the fragment navigation drawer, but I don't really know how to add and change to those new fragments with it. (It also seems like it doesnt change any fragments, just sets the TextView to a the selected position.)

Do you guys may know a good tutorial on how to do that (step by step)? Or can you please give me a hint on how to do it?

EDIT:

I found a solution by myself:

@Override
public void onNavigationDrawerItemSelected(int position) {

    Fragment fragment;

    switch(position){
        case 0:
            fragment = new Fragment_main().newInstance(position+1);
            break;
        case 1:
            fragment = new Fragment_two().newInstance(position+1);
            break;
        default:
            fragment = new Fragment_main().newInstance(position +1);
            break;
    }

    // update the main content by replacing fragments
    FragmentManager fragmentManager = getFragmentManager();
    fragmentManager.beginTransaction()
            .replace(R.id.container, fragment)
            .commit();
}

you just have to add a switch into this method, and also create those classes (and layouts).

I hope this solution helps everyone who also struggles as begginer or with the navigation drawer :)
