Error trying to play sound OnItemClick

Question

I am trying to play sound OnItemClick from a ListView I have set up.

I'm getting the error "The method create(Context, int) in the type MediaPlayer is not applicable for the arguments (new AdapterView.OnItemClickListener(){}, int)" with "create" underlined.

Not 100% sure why I am getting this error, if somebody could help, would be much appreciated.

ListView BoardList = (ListView) findViewById(R.id.BoardList);
BoardList.setChoiceMode(ListView.CHOICE_MODE_SINGLE);

String List[] = {"Play 1", "Play 2", "Play 3", "Play 4", "Play 5", "Play 6", "Play 7", "Play 8", "Play 9" };
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, R.layout.listcustomize, R.id.textItem, List);

BoardList.setAdapter(adapter);
BoardList.setOnItemClickListener(new OnItemClickListener() {
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
        if (position == 0) {
            MediaPlayer  mPlayer = MediaPlayer.create(this, R.raw.Audio1);
            mPlayer .start();
            }
        }
    });

Instead of this inside your MediaPlayer object you should write YourActivityName.this and try again!

MediaPlayer  mPlayer = MediaPlayer.create(YourActivityName.this, R.raw.Audio1);

This error occurs because you are inside the listener and the word this refers to the listener itself and not to your Activity.

Thank you good sir, you have taught somebody something today which will never be forgotten, Thanks. – Jack Aug 21 '13 at 14:22
Maybe you could expand your answer a bit to include an explanation about scope. I am sure future readers struggling with the problem will find it useful! – Eric Tobias Aug 21 '13 at 14:54
It's actually not a scope problem, it's about the basics of programming because in languages like Java you have to understand when the word `this` refers to the object you want – Pavlos Aug 21 '13 at 14:55
And to understand when the keyword `this` and how to use it properly you should ideally have a good grasp on scope. In this case, scope refers to object scope. Here, http://stackoverflow.com/questions/3728062/what-is-the-meaning-of-this-in-java, are some explanations about `this` that can lead to a better understanding of object scope, Basically, when `this` was used in the `onItemClick` method, it was inside the scope of the `OnItemClickListener` object. – Eric Tobias Aug 22 '13 at 10:09
