    ...
    private int mCurrentTabPosition = NO_CURRENT_POSITION;
    private static final int NO_CURRENT_POSITION = -1;
    private ViewPager mPager;
    ...
    int imageArray[];
    String[] stringArray;

    private OnPageChangeListener mPageChangeListener;
    ImagePagerAdapter adapter = new ImagePagerAdapter();

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.home);

        final ViewPager viewPager = (ViewPager) findViewById(R.id.view_pager);

        viewPager.setAdapter(adapter);
...

        setOnPageChangeListener(mPageChangeListener);


        mPageChangeListener = new ViewPager.SimpleOnPageChangeListener() {


            @Override
            public void onPageSelected(int position) { …
