android - Programmatically created Text View gets bad animation

Question

I'm having a problem animating a programmatically created text view. The same method that animates the view works well on views declared in the XML layout file.

The animated View gets multiplied and badly overlapped. Here a gif to better show what happens: gif

Here my code to create the Text View:

private void alza_barraSessione(String _query) {

    int giorno = 30;
    TextView barraVerde =  new TextView(this);
    barraVerde.setId(giorno);
    barraVerde.setText(percentuale + "%");
    barraVerde.setTextAlignment(View.TEXT_ALIGNMENT_CENTER);
    barraVerde.setBackgroundColor(getResources().getColor(R.color.verde_stat));
    barraVerde.setWidth(larghezzabarre);
    barraVerde.setHeight(altezzaVerde);
    layoutBarreStats.addView(barraVerde);

    RelativeLayout.LayoutParams parametri;
    parametri = (RelativeLayout.LayoutParams) barraVerde.getLayoutParams();
    parametri.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
    barraVerde.setLayoutParams(parametri);

    animGrow(barraVerde, altezzaVerde);

}

Here my code to animate the Text View:

private void animGrow(View view, float _altezza) {

    Animation growUp = new ScaleAnimation(1,1,0,1);
    growUp.setInterpolator(new AccelerateDecelerateInterpolator());
    growUp.setDuration(500);

    Animation offSet = new TranslateAnimation(0, 0, _altezza,0);
    offSet.setInterpolator(new AccelerateDecelerateInterpolator());
    offSet.setDuration(500);

    AnimationSet showPercent = new AnimationSet(false);
    showPercent.addAnimation(growUp);
    showPercent.addAnimation(offSet);
    showPercent.setFillAfter(true);
    view.setAnimation(showPercent);
}

I think there's nothing wrong with the code, but some bizarre behaviours of androids Views that I'm missing.
