我正在尝试使用包含在类本身中的列表数据来实现 ArrayAdapter，而不是由调用活动传递。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;
};
}
但是虽然视图是用标题绘制的，但行是空的。我究竟做错了什么？
编辑：修改代码以包含解决方案。谢谢你，@Suaj。
