Fragment Pager Adapter get an error

Question

this is my Fragment Page Adapter.

import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;

public class MyFragmentPagerAdapter extends FragmentPagerAdapter {

    private String[] pageTitle = {
            "Page1", "Page2", "Page3"
    };

    public MyFragmentPagerAdapter(FragmentManager fragmentManager) {
        super(fragmentManager);
    }

    @Override
    public Fragment getItem(int position) {
        switch (position) {
        case 0: return new PageFragment();
        case 1: return new PageFragment2();
        case 2: return new PageFragment3();
        }
        Fragment fragment = new PageFragment();
        Bundle arguments = new Bundle();
        arguments.putString("pageIndex", Integer.toString(position + 1));
        fragment.setArguments(arguments);
        return fragment;

   }

    @Override
    public int getCount() {
        return pageTitle.length;
    }

    @Override
    public CharSequence getPageTitle(int position) {
        return pageTitle[position];
    }

}

Why i get an error in this line: case 0: return new PageFragment(); and Fragment fragment = new PageFragment(); the error is "Type mismatch: cannot convert from PageFragment to Fragment" How to fix? Is possible make it (Viewpager) compatible with Android 2.2 or 2.3?

Answer 1

PageFragment should extend Fragement or another Fragment class (eg ListFragment ). You haven't posted a code for PageFragment so it's hard to say.

Also, I understand you have 3 pages only so the code in getItem is not effective as it will always return in one of the cases of switch and the code after switch will never be reached.
