Utilisation du widget ViewPager

Bonjour
Voici un exemple sur l'utilisation du widget sous Android:

Le code XML:
<android.support.v4.view.ViewPager xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/viewPager"
android:layout_width="match_parent"
android:layout_height="match_parent" />

Le code Java:

public class ViewPagerActivity extends FragmentActivity {
private ViewPagerAdapter mSectionsPagerAdapter;
private ViewPager mViewPager;

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_viewpager);

mSectionsPagerAdapter = new ViewPagerAdapter(getSupportFragmentManager());

mViewPager = (ViewPager) findViewById(R.id.viewPager);
mViewPager.setAdapter(mSectionsPagerAdapter);
}
}
