An error Occurring in the Fun Facts app... Says Textview has to be declared as final. But that also gives an error

Question

Hey guys the error occurs in the last line of code. This android project was thought in the video. But i tried to make me own program...

the error pops up on the line factOutput.setText(newFact);

says "Variable factOutput is accessed from within inner class, needs to be declared as final"

public class MainActivity extends ActionBarActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    TextView factOutput;
    Button Fact_Button;
    Random randomGenrator = new Random();
    final int randomNumber = randomGenrator.nextInt();
    Fact_Button=(Button) findViewById(R.id.factButton);
    factOutput = (TextView) findViewById(R.id.funFact);

    Fact_Button.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            String[] facts={"India is the most improving country in the world",
                            "fact1",fact2","fact3","fact4"};
            String newFact;

            newFact= facts[randomNumber];
            factOutput.setText(newFact);

        }
    });

}

In all of the project videos, most of the variables and objects are declared in the Activity, rather than in the onCreate method of the activity.

If you're using the videos here as a template, just move the lines where you declared factOutput & Fact_Button above the onCreate method (but still in your MainActivity or whatever activity you're in).
