Can you post your FunFactsActivity code, please, rather than a picture of it. There's a couple of things in there that need correcting and I think we can get it working from there.

you mean this one:

package com.Azoz158.funfacts;

import android.app.Activity;
import android.content.DialogInterface;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
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 assign them the views from layout
        Textview_factLable = findViewById(R.id.FactTextView);
        Button showFactButton (Button) findViewById(R.id.showFactButton);
        View.OnClickListener listener = new OnClickListener() {
        ShowFactButton.setOnClickListener();
    }


    @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);
    }
}

Yes.

For starters, if you change this bit:

// change this
Textview_factLable = findViewById(R.id.FactTextView);
// to this
Textview factLable = findViewById(R.id.FactTextView);

Next, orgainse your imports. I don't know the keys to do that - in Mac its Option & Return; hover your mouse over the red lines in View and see what the auto-fix is. That'll sort that out.

A few more bits:

// change this line
Button showFactButton (Button) findViewById(R.id.showFactButton);
 // change to
Button showFactButton = (Button) findViewById(R.id.showFactButton);

Next - 

// change this line
ShowFactButton.setOnClickListener();
// to this
showFactButton.setOnClickListener();

Have a go at those changes and then let's see where you're at. e can make sure you get back on track with this project!
