private TextView factTextView; //private member field for your textView
public void onCreate(){
factTextView = (TextView) findViewById(R.id.factTextView); // you must explicit cast the view to a text view i.e (TextView) this then sets the text view in your class to the textview you have on your layout } }
The class is a blueprint to create an object i.e a car class can create many car objects. A method is an action an instance of the object can perform for example a car can accelerate().
