Creating a chronometer in Android

Just implement the Chronometer in XML or Code and use its start() method to start it and its stop() method to stop it.

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.
