Play a sound from tab fragment with viewpager after a swipe gesture

I am trying to have a sound play on each swipe gesture i have 3 tabs using fragment and viewpager with custom pager adapter, i am running into an error cannot resolve method on the mediaplayer where my sound file is! so far i have tried to create a playSound method and have put the media code in there but everything i try is throwing error! i just want to simply play a sound when user swipes the pages, i have added the mp.start(); in the getitem method and it just doesnt work for me! greatly appreciate someone helping me solve this!

import android.media.MediaPlayer;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
import android.support.v4.view.ViewPager;

import java.util.Locale;


public class ma_pager_adapter extends FragmentPagerAdapter implements ViewPager.OnPageChangeListener{


    public ma_pager_adapter(FragmentManager fm ) {
        super(fm);


    }


    //reference to my soundfile
    final MediaPlayer mp = MediaPlayer.create(this, R.raw.short_whoosh2);

    @Override
    public Fragment getItem(int i) {

        switch (i) {
            case 0:
                tab1 t1 = new tab1();
                return t1;
            case 1:
                tab2 t2 = new tab2();
                return t2;
            case 2:
                tab3 t3 = new tab3();
                return t3;

        }
        return null;
    }

    @Override
    public int getCount() {
        return 3;
    }//set the number of tabs

    @Override
    public CharSequence getPageTitle(int position) {
        Locale l = Locale.getDefault();
        switch (position) {
            case 0:
                return "Top stories";
            case 1:

                return "Members";
            case 2:

                return "Setting";
        }
        return null;
    }

    @Override
    public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {

    }

    @Override
    public void onPageSelected(int position) {
       if(position == 0){
           mp.start();
       }if(position == 1){
            mp.start();
        }if(position == 2){
            mp.start();
        }
    }

    @Override
    public void onPageScrollStateChanged(int state) {

    }
}

getItem is called when it is needed to create fragment, not when it's time to show it.
It's better to make onPageChangeListener for your viewpager in activity and play a sound in onPageSelected.
