                new AdapterView.OnItemClickListener() {

                    @Override
                    public void onItemClick(AdapterView<?> parent, View view,
                            int position, long id) {
                        String dialouge =String.valueOf(parent.getItemAtPosition(position));
                        MediaPlayer mp = MediaPlayer.create(getApplicationContext(), R.raw.b);
                        mp.start();
                    }

                }
        );

    }
}

如果你想说点击不同的列表项目时如何播放不同的声音，那么如下所示：

dia.setOnItemClickListener(new AdapterView.OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
        String dialouge =String.valueOf(parent.getItemAtPosition(position));

        switch(position){
               case 0:

                  MediaPlayer mp = MediaPlayer.create(getApplicationContext(), R.raw.b);
                  mp.start();
                  break;

               case 1:
                  MediaPlayer mp = MediaPlayer.create(getApplicationContext(), R.raw.a);
                  mp.start();
                  break;
               //and so on
        }
    }
});

您可以根据需要更改逻辑。
