Courses Plus Student 367 Pointsyou declare a integer as int x=10; similarly we declare a TextView as "TextView factLabel " .Here TextView is a Data type like int,String,char etc.

protected void onCreate(Bundle savedInstanceState) { //When this object is created...
super.onCreate(savedInstanceState); //Call the parent classes onCreate
setContentView(R.layout.activity_fun_facts); //Use the activity_fun_facts layout to describe the UI
final TextView factLabel = (TextView) findViewById(R.id.factTextView); //Get the TextView with the id of factTextView in the layout file.
Button showFactButton = (Button) findViewById(R.id.showFactButton); //Get the Button with the id of showFactButton in the layout file.
View.OnClickListener listener = new View.OnClickListener() { //Define a new listener to respond when a user clicks on something (such as the showFactButton).
//...
