Dynamically add Fragments in NavigationDrawer

Question

I was using NavigationDrawer from android.support:design library, and it worked fine, but now i have swithed to MaterialDrawer by mikepenz, due to it's obvious features. But now i am stuck.

I want to add Fragment dynamically like i did with android.support:design library, in android.support:design library, i used SharedPreferences, to add/remove Fragments from settings like this:

mNavigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
    @Override
    public boolean onNavigationItemSelected(MenuItem menuItem) {
       mDrawerLayout.closeDrawers();
       if (savedPreferences.getBoolean("add_frag", true)) {
             if (menuItem.getTitle() == "frag") {
             FragmentTransaction xfragmentTransaction = mFragmentManager.beginTransaction();
             xfragmentTransaction.replace(R.id.containerView, new fragFragment()).commit();
       }
    }
}

Now how can i do the same with MaterialDrawer?

There are many ways to change fragment by switch statement or using something like this:

if (position == 0) {                      
    FragmentTransaction fragmentTransaction = mFragmentManager.beginTransaction();
    fragmentTransaction.replace(R.id.containerView, new fragFragment()).commit();
}

But these statement, doesn't help in adding fragment using SharedPreferences. If i try SharedPreferences on above statement Fragment won't change, and this quite obvious.

Please HELP!

The code looks very similar to the one you have currently.

First you build your drawer, and add some items, and add a listener. This listener allow you to execute whatever function you need:

//Create the drawer
new DrawerBuilder()
    .withActivity(this)
    .withToolbar(toolbar)
    .withAccountHeader(headerResult) //set the AccountHeader we created earlier for the header
    .addDrawerItems(
            new PrimaryDrawerItem().withName("Item 1").withIdentifier(1),
            new PrimaryDrawerItem().withName("Item 2").withIdentifier(2)
    )
    .withOnDrawerItemClickListener(new Drawer.OnDrawerItemClickListener() {
        @Override
        public boolean onItemClick(View view, int position, IDrawerItem drawerItem) {
            if (drawerItem != null) {
                if (drawerItem.getIdentifier() == 1) {
                    //do what you want to do for the first item
                } else if (drawerItem.getIdentifier() == 2) {
                    //do whatever you want to do for the second item
                }
            }

            return false;
        }
    })
    .withSavedInstance(savedInstanceState)
    .build();

There may be some other confusion on your side. SharedPreferences store data in your application. This has not really much to do with the MaterialDrawer in general, nor with Fragments
