what's wrong with my code?

I follow exactly what it said on the video, why can't it accept ?

LaunchActivity.java
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;

public class LaunchActivity extends AppCompatActivity {

    public Button launchButton;

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

        launchButton = (Button)findViewById(R.id.launchButton);
        launchButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                // Add your code in here!
              Intent intent = new Intent(this,FlightActivity.class);
              startActivity(intent);

            }
        });
    }
}

Try LaunchActivity.this for the furst parameter of Intent constructor.

Your "this" on intent constructor refers to View.OnClickListener, the anonymous class your intent is created in. It expects current class context which in your case its LaunchActivity, So you just need to replace this with LaunchActivity.this

Intent intent = new Intent(LaunchActivity.this,FlightActivity.class);
startActivity(intent);
