Resource not found TextView
Solution 1:
mRow is an integer. When you call setText(mRow) on line 75, it thinks that you are trying to set the text with a String resource with ID = the value of mRow.
Instead, do:
tRow.setText(Integer.toString(mRow));
Solution 2:
You should always convert other values to string before setting it to textview, like
txtX.setText(Integer.toString(intVal));
