ナビゲーションドロワーの拡張可能リストビューを作成しました。それは働いているが、私はそれからそれからいくつかのサブアイテムを持っているときに引き出しを閉じますが、それはまた、引き出しを閉じます。拡張可能なナビゲーションドロワーがサブアイテムで機能しない
私は持っている。すなわち、この
**Home**
**payment**
**delivery**
**order --> pending order --> complete order**
**exit**
のような引き出し、私はそれが正常に動作しているホームを選択するが、私は順番にクリックしたとき、それは引き出しを閉じます..私は私がクリックしたときに好きたい
注文時に引き出しが開いたままになり、サブアイテムを選択すると閉じます。
ここに完全なコードは以下の通りである： -
