FragmentActivity custom Fragment transition

I am trying to make some kind of transition on Fragments, and i am using default application skeleton in eclipse for creating FragmentActivity. I noticed other posts for specifying custom transition animation from xml, but it is being done on Transaction, and none is using FragmentActivity. (Which is btw much easier.)

I would like to know how to make custom transitions in FragmentActivity. Thanks in advance!

EDIT: Somthing like this but for FragmentActivity.

MusicPlayerActivity.java

public class MusicPlayerActivity extends FragmentActivity {

SectionsPagerAdapter mSectionsPagerAdapter;

ViewPager mViewPager;

    @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    // init pager and set its adapter
    mSectionsPagerAdapter = new SectionsPagerAdapter(
            getSupportFragmentManager());
    mViewPager = (ViewPager) findViewById(R.id.pager);
    mViewPager.setAdapter(mSectionsPagerAdapter);

    //other init code ...
}

    public class SectionsPagerAdapter extends FragmentPagerAdapter {

    public SectionsPagerAdapter(FragmentManager fm) {
        super(fm);
    }

    @Override
    public Fragment getItem(int position) {
        switch (position) {
        case 0:
            return new MainFragment();
        case 1:
            return new AllSongsFragment();
        case 2:
            return new SettingsFragment();
        default:
            return null;
        }
    }

    @Override
    public int getCount() {
        // Show 3 total pages.
        return 3;
    }

    /**
     * Get title for supplied Fragment number.
     */
    @Override
    public CharSequence getPageTitle(int position) {
        Locale l = Locale.getDefault();
        switch (position) {
        case 0:
            return getString(R.string.title_section1).toUpperCase(l);
        case 1:
            return getString(R.string.title_section2).toUpperCase(l);
        case 2:
            return getString(R.string.title_section3).toUpperCase(l);
        }
        return null;
    }
}

    //other methods

}

As you said in your comment, you're using a ViewPager. This is slightly different to performing an animation on a FragmentTransaction.

What you'll want to use is a ViewPager.PageTransformer. There are some details on how to do that here

Question is not much clear to me. But i believe this may serve your purpose.

from: http://developer.android.com/reference/android/app/Activity.html#overridePendingTransition(int, int)

public void overridePendingTransition (int enterAnim, int exitAnim)

Added in API level 5 Call immediately after one of the flavors of startActivity(Intent) or finish() to specify an explicit transition animation to perform next.

As of JELLY_BEAN an alternative to using this with starting activities is to supply the desired animation information through a ActivityOptions bundle to {@link #startActivity(Intent, Bundle) or a related function. This allows you to specify a custom animation even when starting an activity from outside the context of the current top activity.

Parameters enterAnim A resource ID of the animation resource to use for the incoming activity. Use 0 for no animation. exitAnim A resource ID of the animation resource to use for the outgoing activity. Use 0 for no animation.
