拡張可能リストビューの子に2つのテキストビューを追加する方法

Question

2つのテキストビューを展開可能なリストビューに並べて配置しようとしています。残念ながら、スタックオーバーフローで見つかったすべてのソリューションとGoogleの検索は役に立たないことが判明しました。

このリンクは似ていますが、どうやら私が欲しいものソリューション adding two textViews to the header of the expandable listview

は子供ではない拡張可能なリストのヘッダーに2つのテキストビューを配置することではありません。

これは役立つかもしれません。相対レイアウトをプログラムで作成し、相対レイアウトにテキストビューを追加し、相対レイアウトを予想されるビューに追加します。

このようなもの： RelativeLayout relativeLayout = new RelativeLayout（this）; RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams（width、RelativeLayout.LayoutParams.WRAP_CONTENT）;

parentView .addView（relativeLayout）;
