I'd like to know how can I implement in Android a simple chronometer with a start and stop button that displays data in the HH:MM:SS:MsMs format... I've been searching and searching and I have found some classes on google developer, but they didn't give examples and I got lost... Could you direct me to a tutorial/example? I'm just starting out in Android :) Any help would be much appreciated.

Just implement the Chronometer in XML or Code and use its start() method to start it and its stop() method to stop it.
More can be found here: http://developer.android.com/reference/android/widget/Chronometer.html
XML:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<Chronometer
android:id="@+id/chronometer1"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<Button
android:id="@+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Start"
android:onClick="startChronometer"/>
<Button
android:id="@+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Stop"
android:onClick="stopChronometer"/>
</LinearLayout>
Java:
public class Main extends FragmentActivity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.test);
}
public void startChronometer(View view) {
((Chronometer) findViewById(R.id.chronometer1)).start();
}
public void stopChronometer(View view) {
((Chronometer) findViewById(R.id.chronometer1)).stop();
}
}
You might add some code to the startChronometer() method to restart the counter.
