Dynamic form with repeating form

Question

I would like to create a page in android which has to have a form which will repeat based on some value dynamically.

Something like this:

Here form username, password, mobile and address fields are repeated based on number user enters in the the page before this. In this picture the form is repeated twice but it could be any number of times which will be dynamic.

How can I achieve something like this? Can I use listview or recyclerview? If so then how will I have to retrieve the typed in values?

ANS : you should go with recyclerview

How can I achieve something like this?

Create a layout like that for recyclerview single item

how will I have to retrieve the typed in values?

You can get values from RecyclerView.Adapter class

HERE IS THE SAMPLE CODE

Activity.java

public class AddmoreActivity extends AppCompatActivity {

    RecyclerView myRc;
    ArrayList<AddMorePojo> arrayList = new ArrayList<>();
    Button btnGetData;
    AddMoreAdapter adapter;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_addmore);

        myRc = (RecyclerView) findViewById(R.id.myRc);
        btnGetData = (Button) findViewById(R.id.btnGetData);

        myRc.setHasFixedSize(true);
        myRc.setLayoutManager(new LinearLayoutManager(this, LinearLayoutManager.VERTICAL, false));

        AddMorePojo addMorePojo = new AddMorePojo();
        addMorePojo.setAddress("");
        addMorePojo.setUserName("");
        arrayList.add(addMorePojo);


        adapter = new AddMoreAdapter(this, arrayList);
        myRc.setAdapter(adapter);

        btnGetData.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                ArrayList<AddMorePojo> pojoArrayList = adapter.getArrayList();

                for (int i = 0; i < pojoArrayList.size(); i++) {

                    Log.e("Name " + i, pojoArrayList.get(i).getUserName() + "");
                    Log.e("Pass " + i, pojoArrayList.get(i).getPass() + "");
                    Log.e("PHONE " + i, pojoArrayList.get(i).getPhone() + "");
                    Log.e("Address " + i, pojoArrayList.get(i).getAddress() + "");
                }
            }
        });

    }
}

Activity.xml
