final fact label

I'm watching the video Addig the onClick()Method.

The instructor solved a problem that my version of Android Studio doesn't resolve.

One issue is that FactLabel may not have imported (since i had to manually type in an import for Button and TextView.

Screenshot of the options to resolve the red squiggle http://prntscr.com/5ph9x2

Code: package jschwarzwalder.funfacts;

import android.app.Activity; import android.content.DialogInterface; import android.os.Bundle; import android.view.Menu; import android.view.MenuItem; import android.view.View; import android.widget.Button; import android.widget.TextView;

public class FunFactsActivity extends Activity {

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

    //Declare our View Variables and addign them views from layout file
    TextView factlabel = (TextView) findViewById(R.id.factTextView);
    Button showFactButton = (Button) findViewById(R.id.ShowFactbutton);
    View.OnClickListener listener = new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            //The Button was clicked so updage the fact with data
            String fact = "Ostriches can run faster than horses.";

            factLabel.setText(fact);

        }
    }
    showFactButton.setOnClickListener(listener);



}


@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.fun_facts, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();
    if (id == R.id.action_settings) {
        return true;
    }
    return super.onOptionsItemSelected(item);
}

}

I think the problem is a simple typo. Here you declare the variable TextView factlabel = (TextView) findViewById(R.id.factTextView); as factlabel with a lowercase 'l' but then you are referring to the variable as factLabel with an uppercase 'L'.
