Answer 1

//变量：
private SeekBar seekbar;
private MediaPlayer player = null;
player = new MediaPlayer();//初始化
seekbar.setMax(player.getDuration());//设进度条显示
//音量：
audioManager=(AudioManager)getSystemService(AUDIO_SERVICE);
int MaxSound=audioManager.getStreamMaxVolume(AudioManager.STREAM_MUSIC);
maxVolumeTextView.setText(String.valueOf(MaxSound));
SoundseekBar.setMax(MaxSound);
int currentSount=audioManager.getStreamVolume(AudioManager.STREAM_MUSIC);
SoundseekBar.setProgress(currentSount);
SoundseekBar.setOnSeekBarChangeListener(new SeekBarListener());
ProceseekBar2.setOnSeekBarChangeListener(new ProcessBarListener());
