How to select the first item in a navigation drawer and open a fragment on application start

Question

I have created MainActivity with NavigationView. When Activity is opened I want to automatically select the first item in the navigation d

Answer 1

1.) To land to the HomeFragment initially, use this inside your onCreate() in MainActivity:

Fragment fragment = new HomeFragment();
// replacing the fragment
if (fragment != null) {
    FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
    ft.replace(R.id.content_frame, fragment);
    ft.commit();
}

2.) To set the item as selected in navigationDrawer set the item as checked in navigation_menu.xml

 android:checked = "true"
