    private void displayNextMovie() {

Answer 1

I think there are many ways you can achieve displaying the next/prev info to the user. I would ditch the toasts altogether and update the text of a TextView with the name of next/prev movie. That would eliminate your problem and also IMHO makes for better UI.

However, if your design requirements do ask for toast notifications, try:

    private Toast nextMovieRecordToast;
private Toast prevMovieRecordToast;


private void displayNextMovie() {
    if (prevMovieRecordToast != null) prevMovieRecordToast.cancel(); // cancel previous Toast (if user changes movies too often)
    nextMovieRecordToast = Toast.makeText(getApplicationContext(), "Next", Toast.LENGTH_SHORT);
    nextMovieRecordToast.show();}

private void displayPrevMovie() {
    if (nextMovieRecordToast != null) nextMovieRecordToast.cancel();
    prevMovieRecordToast = Toast.makeText(getApplicationContext(), "Prev", Toast.LENGTH_SHORT);
    prevMovieRecordToast.show();    }
