I'm trying to implement Viewpager with a calendar. I'm using the same three instances of the calendar Fragment for testing the ViewPager lets call the smooth motion of transferring one fragment to the next SWIPING. the swiping will not work in the area of the fragment that the layout was created dynamically in the fragment itself but the rest of page(above and below the date buttons)the swiping works great! here is some of the code the entire frag code would not fit so had to edit some declarations and button listener methods

// Main Activity

public class calenderview extends AppCompatActivity {

ArrayList<Fragment> fraglist;

 ViewPager pager;

calenderviewpageradaptor adaptor;

@Override

protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_calenderview);

    fraglist = new ArrayList<>();

    fraglist.add(new Calview_frag()); fraglist.add(new Calview_frag()); fraglist.add(new Calview_frag());

     adaptor = new calenderviewpageradaptor(getSupportFragmentManager(),fraglist);

     pager = (ViewPager)findViewById(R.id.pager);

    pager.setAdapter(adaptor);

}

public class calenderviewpageradaptor extends FragmentStatePagerAdapter {



    ArrayList<Fragment>  adaptorlist;

    public calenderviewpageradaptor(FragmentManager fm,ArrayList<Fragment> list){

        super (fm);

        this.adaptorlist = list;

    }



    @Override

    public int getCount(){

        return 3;

    }

    @Override

    public Fragment getItem(int pos){

                return adaptorlist.get(pos);



    }

      }

}

public class Calview_frag extends Fragment {

    @Override

    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

    }

    private LinearLayout.LayoutParams getdaysLayoutParams() {

                ViewGroup.LayoutParams.WRAP_CONTENT,

        buttonParams.weight = 1;



        return buttonParams;



    }

are you passing the instance of the Fragment to the adapter? No I think. You should pass the list of fragments to the adapter along with fragment manager and should also change the calendarViewPager accordingly.

  List<Fragment> fragments =new ArrayList<>();

  fragments.add(Calview_frag());

  fragments.add(Calview_frag());

  fragments.add(Calview_frag());

      calenderviewpageradaptor adaptor =

                new calenderviewpageradaptor(getSupportFragmentManager(),fragments);
