Get Selected checkbox values and display it in next activity recyclerview

I have a recyclerview which contains Textview,spinner and two checkboxes. While selecting checkbox 1 opens a layout with recyclerview items. Selecting checkbox 2 opens another layout with spinner items. Now I have to collect all the values and display the selected checkbox values in another activity same as recyclerview. Any answer will be valuable

public class Details2Activity extends AppCompatActivity {

RecyclerView rv;
private List<TypesModel> lists;
private APIService service;
private MyAdapter adapter;
private ProgressDialog pDialog;
Button nextButton;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_details2);

    nextButton=findViewById(R.id.details2Next_button);

    pDialog = new ProgressDialog(Details2Activity.this);
    pDialog.setMessage("Please wait...");
    pDialog.setIndeterminate(false);
    pDialog.setCancelable(false);
    pDialog.show();

    Retrofit retrofit=new Retrofit.Builder()
            .baseUrl(URLs.BASE_URL)
            .addConverterFactory(GsonConverterFactory.create())
            .build();

    service=retrofit.create(APIService.class);

    Call<TypeList> call=service.getTypes();
    call.enqueue(new Callback<TypeList>() {
        @Override
        public void onResponse(Call<TypeList> call, Response<TypeList> response) {
            pDialog.dismiss();
            if(response.isSuccessful()){
                lists=response.body().getTypes();
                rv=findViewById(R.id.checkItems);
                adapter=new MyAdapter(lists,Details2Activity.this);
                rv.setLayoutManager(new LinearLayoutManager(Details2Activity.this,LinearLayoutManager.VERTICAL,true));
                rv.addItemDecoration(new DividerItemDecoration(rv.getContext(), DividerItemDecoration.VERTICAL));
                rv.setAdapter(adapter);
            }

        }

        @Override
        public void onFailure(Call<TypeList> call, Throwable t) {
            pDialog.dismiss();

        }

    });

    nextButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            Intent i=new Intent(Details2Activity.this,Details1Activity.class);
            startActivity(i);

        }
    });

}

}

public class TypesModel {

@SerializedName("id")
private int id;

@SerializedName("type")
private String types;

private boolean isSelected;

public TypesModel(int id,String types){
    this.id=id;
    this.types=types;
}

public boolean isSelected() {
    return isSelected;

public void setSelected(boolean selected) {
    isSelected = selected;
}

public int getId() {

}

I have to post this values type[]={"type":1,"number":2,"splitable":1,"for":[3,2],"split":[{"id":1},{"id":2}]}
