包含数据的 ArrayAdapter

Question

我正在尝试使用 class 本身包含的列表数据实现 ArrayAdapter，而不是通过调用 activity 传递。构造函数将只包含上下文，如下所示：

    public class customadapter extends ArrayAdapter<String> {
        private Context mContext;
        private final String[] itemName = {"a", "b", "c"};
        private final String[] itemQty = {"1", "2", "3"};

        public customadapter(Context c) {
            super(c, R.layout.myview);
            mContext = c;
        }

        @Override
        public int getCount() {
          return itemname.length;
        }

        @Override
        public View getView(int position, View view, ViewGroup parent) {
            LayoutInflater inflater = LayoutInflater.from(mContext);
            View rowView = inflater.inflate(R.layout.myview, parent, false);

            TextView fieldName = (TextView) rowView.findViewById(R.id.fieldName);
            TextView fieldQty = (TextView) rowView.findViewById(R.id.fieldQty);
            fieldName.setText(itemName[position]);
            fieldQty.setText(itemQty[position]);
            return rowView;
        };
    }

但是虽然视图是用 headers 绘制的，但行是空的。我做错了什么？

编辑： 修改了代码以包含解决方案。谢谢@Suraj。

使用这个

View rowView = inflater.inflate(R.layout.myview, parent, false);

而不是

View rowView = inflater.inflate(R.layout.myview, null, true);
