Layout XML:

<Chronometer
android:id="@+id/simpleChronometer"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />

Code:

Chronometer simpleChronometer = (Chronometer) findViewById(R.id.simpleChronometer); // initiate a chronometer

simpleChronometer.start(); // start a chronometer
