私は4つのタブを持つアクティビティを持っています。その断片には4つのスイッチがあります。実行時に私は、その状態を変更、OncheckedChangeListenerの登録を解除することにより、プログラム的にその状態を変えていますが、私はここでは、コードアクティビティのフラグメントにOnCheckedChangeListenerを設定する方法

あなたはCompund Listenerの静的インスタンスを持っています。それを使ってそのメソッドを呼び出します。 –
ここでOncheckedChangeListenerの登録を解除しますか？ HallFragmentが呼び出されると、リスナーが登録されます。 –
@ Kaveesh Kanwal私はupdateUI（）メソッドでそれらをderegesteringしています –
