Now your replacing the current text by your new text. You have to change this line:

Texthack.setText("Hello "+ finalI +"\n");

To

Texthack.append("Hello "+ finalI +"\n");

Use append instead of setText https://developer.android.com/reference/android/widget/TextView.html#append(java.lang.CharSequence)
