That's because your assigning the view to etX.text with
etX.Text = pnlBottom.GetView(i)
and android.widget.EditText@427e01a8" with EditText. is the text representation of it.
You should be doing:
etX = pnlBottom.GetView(i)
log(etX.Text)
If pnlBottom is a working panel, then you shouldn't be initializing etX either.
