java当我改变值时，如何自动增加媒体播放器的音量

Question

final float azimuth = Math.round(sensorEvent.values[0]);
    float pitch = Math.round(sensorEvent.values[1]);
    float role = Math.round(sensorEvent.values[2]);

    final double tesla = Math.sqrt((azimuth * azimuth) + (pitch * pitch) + (role * role));
    final Handler handler = new Handler();

    int i = (int) tesla;


    mytext.setText(i + "");
   


    CircularProgressBar circularProgressBar = (CircularProgressBar) findViewById(R.id.progressBar2);
    circularProgressBar.setColor(ContextCompat.getColor(this, R.color.errorcolorcircle));
    circularProgressBar.setBackgroundColor(ContextCompat.getColor(this, R.color.colorAccent));
    circularProgressBar.setProgressBarWidth(getResources().getDimension(R.dimen.activity_vertical_margin));
    circularProgressBar.setBackgroundProgressBarWidth(getResources().getDimension(R.dimen.activity_horizontal_margin));
    int animationDuration = 200; // 2500ms = 2,5s
    circularProgressBar.setProgressWithAnimation(i, animationDuration); // Default duration = 1500ms

我有那个代码，我想在x轴值改变时自动增加媒体播放器的音量。。。表示当x值增大时，音量自动变大，当x值减小时，音量自动变小
