public class MainActivity extends FragmentActivity {

    private TextSwitcher mSwitcher, mSwitcher1;
    private int mCounter = 0;
    String textToShow[] = {
            "Main HeadLine", "Your Message", "New In Technology", "New Articles", "Business News", "What IS New"
    };
    String textToShow1[] = {
            "Main HeadLine", "Your Message", "New In Technology", "New Articles", "Business News", "What IS New"
    };
    int messageCount = textToShow.length;
    // to keep current Index of text
    int currentIndex = -1;

    Timer timer = new Timer();

    public class MyTimerTask extends TimerTask {

        @Override
        public void run() {
            runOnUiThread(new Runnable() {

                @Override
                public void run() {
                    updateTextView();
                }
            });
        }
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.example_layout);

        mSwitcher = (TextSwitcher) findViewById(R.id.textSwitcher);
        mSwitcher1 = (TextSwitcher) findViewById(R.id.textSwitcher01);
        // BEGIN_INCLUDE(setup)
        // Set the factory used to create TextViews to switch between.
        mSwitcher.setFactory(mFactory);
        mSwitcher1.setFactory(mFactory);
        Animation in = AnimationUtils.loadAnimation(this,
                android.R.anim.fade_in);
        Animation out = AnimationUtils.loadAnimation(this,
                android.R.anim.fade_out);
        mSwitcher.setInAnimation(in);
        mSwitcher1.setInAnimation(in);
        mSwitcher.setOutAnimation(out);
        mSwitcher1.setOutAnimation(out);

    }

    @Override
    protected void onStart() {
        super.onStart();
        timer.schedule(new MyTimerTask(), 0, 1000);

    }

    private void updateTextView() {

        int maxIndex = textToShow.length;
        Random random = new Random();
        int generatedIndex = random.nextInt(maxIndex);
        mSwitcher.setText(textToShow[generatedIndex]);
        mSwitcher1.setText(textToShow1[generatedIndex]);
    }

    private ViewFactory mFactory = new ViewFactory() {

        @Override
        public View makeView() {

            // Create a new TextView
            TextView t = new TextView(MainActivity.this);
            t.setGravity(Gravity.TOP | Gravity.CENTER_HORIZONTAL);
            t.setTextAppearance(MainActivity.this, android.R.style.TextAppearance_Large);
