showFactButton.OnClickListener(listener) throws an error that on hover says 'Expected Class or Package.'

What's going on?

package com.sixtytendev.funfacts;

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

import org.w3c.dom.Text;


public class FunFactsActivity extends Activity {

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

        //Declare/assign to variables
        final 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) {
                String fact = "Ostriches can run faster than horses?";
                factLabel.setText(fact);
            }
        };
        showFactButton.OnClickListener(listener);
    }

It's all imported properly.

Sorry, i missed what you actually did wrong.

you need to type factButton.setOnClickListener instead of what you are using ( factButton.onClickListener)

change it to setOnClickListener, and you should be fine.

Are you sure that's all of your code?

If so, you are missing a closing brace for the class definition

put another "}" at the end of the file

No, there's a bit more but it's properly closed.

The error is 'Error:(31, 23) error: cannot find symbol method OnClickListener(OnClickListener).' Line 31 is when it's called, 23 when it's declared.
