屏幕锁定或休眠时如何暂停和播放媒体播放器？

Question

I am using Java and xml to create an application for the summer. This app has music in the background, that I would like to pause and then play depending on the state it is in. When i lock my screen the music does not pause it keeps playing. How would i fix this, I have tried to use the method on this site:

I have not been able to successfully get a working prototype, and I am working in android studio.

        myPlayer = MediaPlayer.create(c(this is the context), myField(This is the raw file));
        myPlayer.start();
        myPlayer.setLooping(true);
        myPlayer.setVolume(0.7f,0.7f);

What could I add to pause the mediaplayer when the lock button is pressed or the phone goes to sleep and then play it when the phone is unlocked?

    @Override
    protected void onPause() {
        super.onPause();

        if (myPlayer != null) {
            myPlayer.pause();
        }
    }

    @Override
    protected void onResume() {
        super.onResume();
        if (myPlayer != null) {
            myPlayer.start();
        }
    }
