2つを追加しましたLinearLayoutsこれらのレイアウトでは、動的にCheckboxesを追加します。最終的な目的は、データをデータベースに格納することです。java.lang.IllegalStateExceptionを取得しました：指定された子が既に親を持っています
私はこのエラーを取得しています：
java.lang.RuntimeException: Unable to start activity
ComponentInfo{com.freedomkitchen.sonali.freedomkitchen/com.freedomkitchen.sonali.freedomkitchenAndroidApp.AddRecipes}:
java.lang.IllegalStateException: The specified child already has a
