我创建了音乐播放器应用程序,我想以编程方式设置volume 上/下.

我想实现两个另一个Button用于增加/减少量,并设置到媒体播放器.

请帮我在android中访问音量增大/减小.

活动代码:

control = (ImageView) findViewById(R.id.control);
mediaPlayer = new MediaPlayer();
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
control.setOnClickListener(pausePlay);
control.setBackgroundResource(R.drawable.pause);
control id is my play and pause button :
{
            // TODO Auto-generated method stub
            // TODO Auto-generated method stub

            if (playPause) {
                control.setBackgroundResource(R.drawable.play);
                if (mediaPlayer.isPlaying())
                    mediaPlayer.pause();
                media.stop();
                intialStage = false;
                playPause = false;

            } else {
                control.setBackgroundResource(R.drawable.pause);
                if (intialStage) {
                    new Player()
                            .execute("http://streaming.shoutcast.com/MUKILFMRADIO");
                } else {
                    if (!mediaPlayer.isPlaying())
                        mediaPlayer.start();
                } …
