我正在使用节标题处理列表视图，现在我有一个这样的 ArrayAdapter：
header = new ArrayAdapter<String>(context, R.layout.header);
我正在以这种方式使用标题：
view = header.getView(sectionnum, convertView, parent);
if (view != null) {
TextView headerTitle = (TextView) view.findViewById(R.id.header_title);
}
现在我不想使用R.layout.headerxml，而是我有一个我需要使用的以编程方式创建的布局，如何使用它而不是 xml？
just extend ArrayAdapter and override its getView method
header = new ArrayAdapter<String>(context, R.layout.header) {
@Override
public View getView (int position, View convertView, ViewGroup parent) {
if (converView == null) {
// inflate convertView;
}
// fill up covertView
return convertView;
}
}
这是要回答的区域，但我可以弄清楚如何将其作为评论发布到此处的其他评论。
所以，我遇到了同样的问题。我认为那是因为如果我没有这个 ID，因为我正在尝试动态使用 all。
我已经尝试调用我的构造函数 put (context, 0, list-of-Objects)
还有其他解决方案可以尝试吗？

}
contextitem contextItem = objects.get(position);
holder.name.setText(contextItem.getName());
int count = contextItem.getCount();
