}

@Override

    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.menu_main, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
        case R.id.action_settings:
            // User chose the "Settings" item, show the app settings UI...
            Intent in = new Intent("com.ajjunaedi.jmnanywhere.AboutActivity");
            startActivity(in);
            return true;

        default:
            return super.onOptionsItemSelected(item);
    }
}

}

You need to add FragmentManager to add/remove/replace a fragment.

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

getSupportFragmentManager() = Return the FragmentManager for interacting with fragments associated with this activity.

.beginTransaction() = Start a series of edit operations on the Fragments associated with this FragmentManager.

R.id.fragment is the id of the container where you be putting your fragment.

for more info refer to this post - What does FragmentManager and FragmentTransaction exactly do?

EDIT: you will add this after your switch statement. I hope this is the answer that you are looking for.

Add this to your xml file. inside the baselayout

<RelativeLayout
    android:id="@+id/fragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

Resize it to your desire. or you can simply add the line android:id="@+id/fragment" to your baselayout.

You need to add a layout(Linear/Relative) inside your layout in your xml file. — mark.jon, Sep 01 '16 at 03:05
