Dynamic TextSwitcher after 5 sec

Question

Hello,

I am working with Android. Can anybody tell me how can i create something like... When i click one button once....numerical digits will show me automatically as increasing order like 1,2,3,4......so on with switched between two digits, after every 5 sec...I mean it shows only latest one digits like counter.

I tried with this

public class TextSwitcher1 extends Activity implements ViewSwitcher.ViewFactory {

private TextSwitcher mSwitcher;
private int mCounter = 0;

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

    setContentView(R.layout.text_switcher_1);

    mSwitcher = (TextSwitcher) findViewById(R.id.switcher);
    mSwitcher.setFactory(this);


    Animation in = AnimationUtils.loadAnimation(this,
            android.R.anim.fade_in);
    Animation out = AnimationUtils.loadAnimation(this,
            android.R.anim.fade_out);
    mSwitcher.setInAnimation(in);
    mSwitcher.setOutAnimation(out);
// Button nextButton = (Button) findViewById(R.id.next); // nextButton.setOnClickListener(this);

    updateview();

}

public void hi() {
    mCounter++;
    mSwitcher.setText(String.valueOf(mCounter));
    mSwitcher.addView(makeView());
}

private void updateview() {

    int delay = 5000;   // delay for 5 sec.
    int period = 5000;  // repeat every sec.
    Timer timer = new Timer();

    timer.scheduleAtFixedRate(new TimerTask() {
            //private View v;

            public void run() {
                // Task here ...
                hi();

                Log.d("Android", "hi value : " + mCounter);
            }
        }, delay, period);      

      }


public View makeView() {
    TextView t = new TextView(this);
    t.setGravity(Gravity.TOP | Gravity.CENTER_HORIZONTAL);
    t.setTextSize(36);
    Log.d("Android", "makeView value : " + mCounter);
    return t;
}
}
