私はrecyclerViewを使用していて、arrayListとしてデータをロードしています。 arrayListの項目が7個未満の場合、クラッシュは発生しません。IndexOutOfBoundsException：不一致が検出されました
そうでなければ、私は、この致命的なエラーがあります：
java.lang.IndexOutOfBoundsException: Inconsistency detected. Invalid view holder adapter positionViewHolder{3b1755be position=7 id=-1, oldPos=-1, pLpos:-1 no parent}
誰でも助けることができますか？
