android - 从原始文件夹播放声音，与 ListView 的每一行成比例

Question

我想在以下代码中与列表的每一行成比例地播放原始文件夹中的声音文件，其意思是例如用lorem播放1.mp3，用ipsum和2.mp3播放...

我应该在代码中添加什么？

请帮我...

我的代码:

    public class InflatList extends ListActivity {
private TextView selection;
private static final String[] items = {"lorem", "ipsum", "dolor", "sit", "amet", "consectetuer", "adipiscing", "elit", "morbi", "vel", "ligula", "vitae", "arcu", "placerat", "ante", "porttitor", "sodales", "pellentesque", "augue", "purus"};

  @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    setListAdapter(new IconicAdapter());
    selection = (TextView)findViewById(R.id.selection);
  }

  //=====================
  //New Class Starts Here
  //=====================
  class IconicAdapter extends ArrayAdapter<String> {

    public IconicAdapter() {
        super(InflatList.this, R.layout.row, items);
    }

    public View getView(int position, View convertView, ViewGroup parent){
        LayoutInflater inflater = getLayoutInflater();
        View row = inflater.inflate(R.layout.row, parent, false);

        TextView label = (TextView)row.findViewById(R.id.label);
        label.setText(items[position]);
        ImageView icon = (ImageView)row.findViewById(R.id.pic);
            ImageButton btnplay = (ImageButton)row.findViewById(R.id.btnplay);

        return(row);
    }
 }
 }

假设您已经尽早播放了声音

因此，您可以从onListItemClick上的获得关注

 @Override
protected void onListItemClick(ListView l, View v, int position, long id) {
 // TODO Auto-generated method stub
 super.onListItemClick(l, v, position, id);

 // find which item clicked from the id,

 //Place your code here for play video
