create fragment inside ViewPager android

Question

MainActivity(extends fragmentActivity) has listview which calls listviewadapter within which have a ViewPager with ViewpagerAdapter now if i need to generate 5 fragments within ViewPager how to pass getFragmentManager() to adapter.

MainActivity [fragmentActivity] ----> Listview ----> ListviewAdapter [Custom BaseAdapterAdapter with getview of layout ViewPager] ---> ViewPager ---> ViewPageAdapter [ i need to create 5 fragments based on position? ]

It will be too long if i paste the whole code so i have attached only

public class ViewPagerAdapter extends PagerAdapter  {    
    ArrayList<ModelClass> arrayModelClasses = new ArrayList<ModelClass>();
    Context mcontext ;
    LinearLayout layouttest;

    final int PAGE_COUNT = 5;
    private String titles[] = new String[] { "Villa ","", "" ,"","",""};

    private int[] imageResId = { R.drawable.transparant,R.drawable.ic_action_place, R.drawable.icon_3d1,
            R.drawable.icon_flooplan,R.drawable.icon_gallery,R.drawable.icon_location };

    @SuppressLint("NewApi")
    @Override
    public void finishUpdate(ViewGroup container) {
        // TODO Auto-generated method stub
        super.finishUpdate(container);
    }

    public ViewPagerAdapter(ArrayList<ModelClass> arrayModelClasses , Context context) {
        super();
        this.arrayModelClasses = arrayModelClasses;
        this.mcontext= context;
    }

    @Override
    public boolean isViewFromObject(View collection, Object object) {
        return collection == ((View) object);
    }

    View view;

    @Override
    public Object instantiateItem(View collection, int position) {
        if (position == 0) {
            //need to call fragment 1
        }if (position == 1) {
        //need to call fragment 2
        }if (position == 2) {
        //need to call fragment 3
        }if (position == 3) {
        //need to call fragment 4
        }if (position == 4) {
        //need to call fragment 5
        }   
        return view;
    }

    @Override
    public void destroyItem(View container, int position, Object object) {
        ((ViewPager) container).removeView((View) object);
    }

    @Override
    public CharSequence getPageTitle(int position) {
         Drawable image = mcontext.getResources().getDrawable(imageResId[position]);
            image.setBounds(0, 0, image.getIntrinsicWidth(), image.getIntrinsicHeight());
            SpannableString sb = new SpannableString(" " +  titles[position] );
            ImageSpan imageSpan = new ImageSpan(image, ImageSpan.ALIGN_BOTTOM);
            sb.setSpan(imageSpan, 0, 1, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
            return sb;
    }

    @Override
    public int getCount() {
        return PAGE_COUNT;
    }

}

link but it uses FragmentPagerAdapter for viewPager and passed the getSupportFragmentManager from FragmentActivity but its not possible with 2 adapters so help.

Question: How to create fragment within viewPager which is inside listview. sorry if its confusing.

Thanks,

Answer 1

Considering you did not post your ListView Adapter I'll assume you extend BaseAdapter (either way it'll be similar). On the getView(...) method instantiate a new ViewPagerAdapter and set it to the PagerAdapter defined in the list item xml.

Note: having a ViewPager inside the ListView (and specially while loading the items that way) could cause low performance.

I've attached fragments inside ViewPager with the code as follows

public class IntroslideActivity extends FragmentActivity {

 private static int NUM_PAGES = 5;          

    private ViewPager mPager;


    private PagerAdapter mPagerAdapter;


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



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

/** * A simple pager adapter that represents 5 {@link ScreenSlidePageFragment} objects, in * sequence. */ private class ScreenSlidePagerAdapter extends FragmentPagerAdapter{

     protected  final int[] ICONS = new int[] {
         R.drawable.ic_message,
         R.drawable.ic_phone,
         R.drawable.ic_message,
         R.drawable.ic_message,
         R.drawable.ic_message
 };

    public ScreenSlidePagerAdapter(android.support.v4.app.FragmentManager fm) {
        super(fm);
    }

    @Override
    public android.support.v4.app.Fragment getItem(int position) {
        android.support.v4.app.Fragment frm = null;
        System.out.println("scrolling position"+position);
        if(position==0){

            frm=ScreenSlidePageFragment.create(position);
        }
        else if(position==1){
            frm=Screenslidetwo.create(position);
        }
        else if(position==2){
            frm=Screenslidethree.create(position);
        }
        else if(position==3){
            frm=Screenslidefour.create(position);
        }
        else if(position==4){
            frm=Screenslidefive.create(position);
        }
        return frm;
    }

    @Override
    public int getCount() {
        return NUM_PAGES;
    }
    public void setCount(int count) {
        if (count > 0 && count < 5) {
            NUM_PAGES = count;
            notifyDataSetChanged();
        }
    }


}



        mPagerAdapter = new ScreenSlidePagerAdapter(getSupportFragmentManager());
        mPager.setAdapter(mPagerAdapter);

} }
