foun

Answer 1

add these two import

  import android.support.v4.app.FragmentManager;
    import android.support.v4.app.FragmentTransaction;

for example

   FragmentA fragmentA = new FragmentA();
    FragmentManager fragmentManager =getSupportFragmentManager();
    FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
    fragmentTransaction.add(R.id.id_parent_fragment,fragmentA);
    fragmentTransaction.commit();

consider FragementA is the fragment that you want to insert in the activity which in this case is the container in the activity id_parent_fragment
