How to change the activity inside the Frame when the button is clicked?

Question

Android

public void openFilms(View view){
        /* Заменяет основной активити
        Intent intent = new Intent(this, FilmsActivity.class);
        startActivity(intent);
        */

    }

For example, take FrameLayout fl = (...) ... (R.id. ...);
Please show me how to load fl FilmsActivity inside if it is not already included in it... Thanks in advance :)
