The showTextView is in red
//Declare our view variables and assign the the Views from the layout file
TextView factLabel = findViewById(R.id.showfactTextView);

Simply go to your layout.xml file where you design the layout and check if the id of the TextView under consideration is called showfactTextView , if it's in red then it doesn't probably match with the id in your xml file. Both should have the same name

24,828 PointsI'm not sure if Gunjeet Hatter answered the question, but do not forget to add the cast (TextView) before findViewById like: TextView factLabel = (TextView) findViewById(R,id,showfactTextView);

14,483 PointsOh my bad! Glad you observed Paolo. Thanks. Yes Jared, you need to add a cast too.

//Declare our view variables and assign the the Views from the layout file
