Try clicking on the line of code and press alt + enter on your keyboard, then press enter on - cast to "android.widget.textview".

It should look something like this:

"TextView factLabel = (TextView) findViewById(R.id.factTextView);"

First, try to go back to your XML file and make sure that your textview has the same id name. Also, there seems to be a mistake on your code.

try this

factLabel = (TextView)findViewById(R.id.factTextView);

Lastly, make sure its a TextView not something else, for instance, an EditText.
