        viewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {

            @Override
            public void onPageSelected(int position) {
                // on changing the page

            @Override
            public void onPageScrolled(int arg0, float arg1, int arg2) {
            }

            @Override
            public void onPageScrollStateChanged(int arg0) {
            }
        });
    }

    @Override
    public void onTabReselected(Tab tab, FragmentTransaction ft) {
    }

    @Override
    public void onTabSelected(Tab tab, FragmentTransaction ft) {
        // on tab selected
        // show respected fragment view
        viewPager.setCurrentItem(tab.getPosition());
    }

    @Override
    public void onTabUnselected(Tab tab, FragmentTransaction ft) {
    }

}

Answer 1

If you are using a TabLayout, just do this (This example uses three tabs):

 //An array containing your icons from the drawable directory
 final int[] ICONS = new int[]{
            R.drawable.icon_1,
            R.drawable.icon_2,
            R.drawable.icon_3
    };

    //Get reference to your Tablayout
    TabLayout tabLayout = (TabLayout) findViewById(R.id.tabs);
    tabLayout.setupWithViewPager(mViewPager);

    tabLayout.getTabAt(0).setIcon(ICONS[0]);
    tabLayout.getTabAt(1).setIcon(ICONS[1]);
    tabLayout.getTabAt(2).setIcon(ICONS[2]);

Answer 2

Add .setIcon(resources.getDrawable(DrawableIDHere)) in your for loop, and also alter your for loop a bit.

// Adding Tabs
for (int i=0; i < tabs.length; i++)
{
actionBar.addTab(actionBar.newTab().setText(tabs[i])
                         .setIcon(resources.getDrawable(ICONS[i]))
                         .setTabListener(this));
}//endfor

Also, don't forget to put the right drawable ID's in your ICONS array!

Answer 3

// here you add an array of your icon   
 final int[] ICONS = new int[] {
                    R.drawable.ic_launcher,
                    R.drawable.ic_launcher,
                    R.drawable.ic_launcher,
                    R.drawable.ic_launcher,
            };

    // add this following code to solve your problem
    // here NewsFeedActivity.this.getResources() is used to get the drawable folder resource
    // instead of NewsFeedActivity you have to use your activity name here  
    for (int i=0; i < tabs.length; i++)
            {
            actionBar.addTab(actionBar.newTab().setText(tabs[i])
                                     .setIcon(NewsFeedActivity.this.getResources().getDrawable(ICONS[i]))
                                     .setTabListener(this));
            }//endfor

Hi check out the ViewPagerIndicator library.

This is very good example for swipe-able tabs.
