동영상 재생은 일단 위 코드처럼 하면 된다. 이때 부연설명을 하자면 아래의 코드처럼

 

 videoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {

            @Override

            public void onPrepared(MediaPlayer mediaPlayer) {

                Toast.makeText(getApplicationContext(), "동영상 준비됨.", Toast.LENGTH_LONG).show();

            }

        });

 

비디오뷰에 setOnPreparedListener로 onPrepared메서드를 오버라이드한 OnPreparedListener를 설정한다면 requestFocus로 시작하여 비디오 재생 준비가 끝나면 onPrepared메서드가 호출되어 준비종료가 됬다는 것을 알수 있다. 그 이후로 동영상을 재생시켜주면 된다.
