To count down

You'll use a TextField and update its content using CountDownTimer, or check Rahul's answer in this same question.

To count up

In your Activity

import android.widget.Chronometer;

...

private Chronometer crono;

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

 setContentView(R.layout.screen_crono);    

 this.crono = (Chronometer) findViewById(R.id.calling_crono);

    startCrono();
}

public void startCrono() {
 crono.setBase(SystemClock.elapsedRealtime());
 crono.start();
}

To stop it

crono.stop();

In the XML Layout screen_crono

To set it inside a TextView, I don't think that's possible. Place it to its right or to its left, depending on what you want.

If this is not what you wanted, I hope it helps someone else.
