Answer 1

在展开式列表视图适配器中，您将使用getGroupView()或getChildView()方法对行进行充气，在那里您将访问TextView以使用所需的字符串填充它们。

只需致电.setTextSize(*float*)

具有视图持有者模式的getGroupView()示例：

public View getGroupView(final int i, boolean b, View view, ViewGroup viewGroup) {
    ViewHolder holder;

    if (view == null) {
        holder = new ViewHolder();
        view = mInflater.inflate(R.layout.your_row, viewGroup, false);
        TextView tvName = (TextView) view.findViewById(R.id.your_textview);
        holder.name = tvName;
        view.setTag(holder);
    } else {
        holder = (ViewHolder)view.getTag();
    }
holder.name.setText("your desired text value");
holder.name.setTextSize(22.0f);
}
