I have a some problem regarding inflating and re-using the same TextView.
Its like its trying to overwrite the same textview over and over again or something and it can
Try this:
View mainlayout = inflater.inflate(R.layout.days_monday_inflate, null);
for (int i = 0; i < 10; i++) {
row = new TableRow(this);
View layout_number = inflater.inflate(R.layout.inflate_number, null);
TextView number = (TextView) layout_number.findViewById(R.id.Number);
number.setTag(i);
number.setText(Integer.toString(i));
row.addView(number);
}
