ListView in Android 2.2

view story

http://stackoverflow.com – I am developing an application for android 2.2, in which I would like to have a ListView with the possibility of onLongClickListener method. So far I have been using this example, but now I got stuck at getLoaderManager().initLoader(0, null, this); because my eclipse claims that it can't find the method. I've got this: import android.app.ListActivity; import android.database.Cursor; import android.os.Bundle; import android.widget.SimpleCursorAdapter; import android.widget.TextView; import android.support.v4.app.LoaderManager.LoaderCallbacks; import android.support.v4.content.CursorLoader; imp (HowTos)
