I have a question In this code that I currently have, located in a fragment contains a "swich case" that opens a different activity, now what I did is create another an activity 2 which loads 12 fragments with a viewPager, which would replace these 12 activities Does anyone know how to do it so that in each "case" there will be a fragment in specific activity 2

THIS IS THE FRAGMENT WHERE THE LINKS CONTAIN

public class ElRecorridoFragment extends Fragment {
// TODO: Rename parameter arguments, choose names that match
// the fragment initialization parameters, e.g. ARG_ITEM_NUMBER
private static final String ARG_PARAM1 = "param1";
private static final String ARG_PARAM2 = "param2";

// TODO: Rename and change types of parameters
private String mParam1;
private String mParam2;

private OnFragmentInteractionListener mListener;

RecyclerView recyclerEstaciones;
ArrayList<EstacionesVo> listaEstaciones;

public ElRecorridoFragment() {
    // Required empty public constructor
}



public static ElRecorridoFragment newInstance(String param1, String param2) {
    ElRecorridoFragment fragment = new ElRecorridoFragment();
    Bundle args = new Bundle();
    args.putString(ARG_PARAM1, param1);
    args.putString(ARG_PARAM2, param2);
    fragment.setArguments(args);
    return fragment;
}

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    if (getArguments() != null) {
        mParam1 = getArguments().getString(ARG_PARAM1);
        mParam2 = getArguments().getString(ARG_PARAM2);
    }

Receive notifications from different FCM "senders" ORACLE - Insert from a Select

It is a good solution that you perform, instead of several Activities having a single Activity with a FragmentPagerAdapter that contains the Fragments that would represent several Activities.

If you have the fragments loaded in the viewPager and you want to open a specific one, you can use the setCurrentItem () , in which you define the index of the element in the viewPager you wish to view.

For example if you want to visualize the third Fragment:

mViewPager.setCurrentItem(2);

To define which Fragment would be displayed before loading the Activity that contains the Fragments you can send this data through a bundle when loading the Activity

intent.putExtra("indiceFragment", 2);   
startActivity(intent);

You receive the data in the Activity that contains the Fragments and move the pager to the desired Fragment within the viewPager.

Bundle datos = this.getIntent().getExtras();  
int indiceFragment = datos.getInt("indiceFragment");
mViewPager.setCurrentItem(indiceFragment);
