Implémentation d’un dossier dynamique

Bonjour
Voici un exemple sur l'implémentation d’un dossier dynamique:

public class PersonnesLiveFolder extends Activity {
public static final Uri CONTENT_URI = Uri.parse(
"content://com.ctc.provider.personnarium/personnes/live_folders");
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
final Intent intent = getIntent();
final String action = intent.getAction();
if (LiveFolders.ACTION_CREATE_LIVE_FOLDER.equals(action)) {
final Intent intent = new Intent();
intent.setData(CONTENT_URI);
intent.putExtra(LiveFolders.EXTRA_LIVE_FOLDER_NAME, "Personnes");
intent.putExtra(LiveFolders.EXTRA_LIVE_FOLDER_ICON,
Intent.ShortcutIconResource.fromContext(this, R.drawable.icon));
intent.putExtra(LiveFolders.EXTRA_LIVE_FOLDER_DISPLAY_MODE,
LiveFolders.DISPLAY_MODE_LIST);
setResult(RESULT_OK, intent);
} else {
setResult(RESULT_CANCELED);
}
finish();
}
}
