Seting the duration of Media Player media in Android

问题

I want to set the time duration for MediaPlayer. Here is my code:

MediaPlayer play = MediaPlayer.create(getApplicationContext(),R.raw.beepsound);
play.start();

You can use Timer which will be updated every 1000 milliseconds. Then set time to a TextView or what ever you want.

if (player != null) {
    player.start();
    timer = new Timer();
    timer.scheduleAtFixedRate(new TimerTask() {
        @Override
        public void run() {
            runOnUiThread(new Runnable() {
                @Override
                public void run() {
                    if (player != null && player.isPlaying()) {
                        tv.post(new Runnable() {
                            @Override
                            public void run() {
                                tv.setText(player.getCurrentPosition());
                            }
                        });
                    } else {
                        timer.cancel();
                        timer.purge();
                    }
                }
            });
        }
    }, 0, 1000);
}
