私のアプリでは、私はcheckboxとedittext（数量）でlistviewを持っています最終的にfragment1のボタンを送信します。私はいくつかのチェックボックスを選択し、edittextに値を入力し、submitボタンをクリックしてfragment2に移動します。どのようにリストビューのチェックボックスと編集テキスト値でonresume
私がもう一度fragment1に戻った場合は、私が選んだチェックボックスをチェックして、editextでも量値を設定したいと思います。
誰も私に助けてください..

ありがとう！
LunchFragment.MenuItemクラスのインスタンス変数 "selFlag"の目的を教えてください。 –
selFlagがチェックされているかどうかチェックされているかどうかチェックしてください。 – hikoo
