Attempt to invoke virtual method 'void android.widget.TextView.setTypeface(android.graphics.Typeface)' on a null object reference in java

Hello stack overflow community. i am working on a quiz game and im getting the following error which i think is due to the fact that the textview im trying to create keeps going to null

java.lang.NullPointerException: Attempt to invoke virtual method 'void android.widget.TextView.setTypeface(android.graphics.Typeface)' on a null object reference
