How to order my registers by date of a database with sqlite android

i have a problem

Im wanna order my register by date for example:

• 01/01/2014


• 02/01/2014


• 03/01/2014

A have a DATETIME field:



fechacobro DATETIME DEFAULT CURRENT_DATE

I insert my register:

FUNCTION

private ContentValues contvaladdcobro(String fechacobro){
        ContentValues valor = new ContentValues();
        valor.put("fechacobro", fechacobro);
        return valor;
    }
    public void **addcobro**(String fechacobro){
        try {
            db.insert("cobranza", null, contvaladdcobro(fechacobro));
            Log.i("dato insertado: ","Exitoso");
        }catch (Exception e){
            Log.i("error al insertar",e.toString());
        }

   }

INSERTING

sqlite.addcobro("01/01/2014");

sqlite.addcobro("02/01/2014");

sqlite.addcobro("03/01/2014");

here all is OK, but when i want show my registers, use this funtion:

public Cursor showregisters(){
        String[] columnas = new String[]{"fechacobro"};
        return db.query("cobranza",columnas,null,"date(fechacobro)",null,null,null);
    }

I CALL THIS FUNTION

Cursor cursor = sqlite.showregisters();

cursor.movetofirts;

do{
    Log.i("mensaje",cursor.getString(0));
}while(cursor.movetonext);

My result is just:

01/01/2014

Someone can help me?
