Looks like you are calling setText(int resid) whereas what you really want is setText(CharSequence text): http://developer.android.com/reference/android/widget/TextView.html#setText(int) http://developer.android.com/reference/android/widget/TextView.html#setText(java.lang.CharSequence)
Convert your integer to a String before calling to fix it. Use Integer.toString(int i) or concatenate it to an empty String, for example. Also, random.nextInt(9) returns 0 to 8, both ends inclusive.
