To customize SlidingTabLayout the way you want, you only need to modify the method populateTabStrip():

public void populateTabStrip() {
        final PagerAdapter adapter = mViewPager.getAdapter();
        final View.OnClickListener tabClickListener = new TabClickListener();

        for (int i = 0; i < adapter.getCount(); i++) {
            View tabView = null;

            tabView = LayoutInflater.from(getContext()).inflate(R.layout.tab_layout, mTabStrip,
                    false);

            ImageView iconImageView = (ImageView) tabView.findViewById(R.id.tab_layout_icon);
            iconImageView.setImageDrawable(getContext().getResources().getDrawable(getIconResourceArray()[i]));

            tabView.setOnClickListener(tabClickListener);

            mTabStrip.addView(tabView);
        }
    }

Your layout could be something like that:

The way you implement the getResourceArray() method is up to you. Here is how I did:

public class IconSlidingTabLayout extends HorizontalScrollView {
    private Integer[] mIconResourceArray;

    ...

    public Integer[] getIconResourceArray() {
        return mIconResourceArray;
    }

    public void setIconResourceArray(Integer[] mIconResourceArray) {
        this.mIconResourceArray = mIconResourceArray;
    }
}

In the activity:

mSlidingTabLayout = (IconSlidingTabLayout) findViewById(R.id.icon_sliding_tab_layout);
Integer[] iconResourceArray = { R.drawable.news_tab_icon,
        R.drawable.challenges_tab_icon, R.drawable.trophies_tab_icon,
        R.drawable.leaderboard_tab_icon };
mSlidingTabLayout.setIconResourceArray(iconResourceArray);

Be aware that in order to have access to R.layout.tab_layout*, you have to import yourpackage.R instead of android.R as it is by default in SlidingTabStrip.
