Android: Binden von Daten an das listview aus der Datenbank

Ich versuche, ziehe mir Daten aus meiner SQLite DB und Anzeige in einer listview, das ist was ich habe, so weit, aber es stellt nur den ersten Datensatz in der Listenansicht.
Ich denke, die "while (mCursor.moveToNext()){" etwas ändern muss, wissen aber nicht genau wie. Der original-code, der jeder Datensatz in einer textview in einer neuen Zeile jedes mal.

    if (mCursor == null){
        mCursor.close();
        Log.w("cursor", "null cursor");
    }       

        mCursor.moveToFirst();
    String[] s = null;


    while (mCursor.moveToNext()){

        s = new String[] { foodNameColumn, proteinColumn, fatColumn, carbsColumn };

        mCursor.moveToNext();
    }


    SimpleCursorAdapter adapter = new SimpleCursorAdapter(this, 
            R.layout.aa_four_column,
            mCursor, 
            s, 
            new int[] { R.id.txtCol1, R.id.txtCol2, R.id.txtCol3, R.id.txtCol4 }, 0);

    lvDB.setAdapter(adapter);

Update:

Habe ich geändert, so daß nur dieser code in der onCreate-Methode, aber das gleiche passiert, ein Element angezeigt, wenn es mehrere Dinge in der DB.

            mCursor = dataBase.select("SELECT * FROM " + TABLE_NAME);

        SimpleCursorAdapter adapter = new SimpleCursorAdapter(this, 
                    R.layout.aa_four_column,
                    mCursor, 
                    new String[] { foodNameColumn, proteinColumn, fatColumn, carbsColumn }, 
                    new int[] { R.id.txtCol1, R.id.txtCol2, R.id.txtCol3, R.id.txtCol4 }, 0);

        lvDB.setAdapter(adapter);
