It doesn't say showfactTextView

The showTextView is in red

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

Hi Jared,

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

I'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);

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

        setContentView(R.layout.activity_stupidfactsftw);

        //Declare our view variables and assign the the Views from the layout file
        TextView factLabel = (TextView)findViewById(R.id.showfactTextView);
        Button showFactButton;

The showfactTextView is in red
