マルチチェックダイアログでSearchViewを実装する - Android

Question

ユーザが複数の項目を選択できるように多肢選択ダイアログを実装しました。私はダイアログ内でsearchviewを実装したいと思います。しかし、問題は次のとおりです。 複数選択ダイアログで配列が処理されるため、検索結果に基づいてリストビューを変更できません。私は、この実装をプロジェクトのいくつかのアクティビティでいくつかの で使用しました。これらの多肢選択ダイアログに検索ビューを含めたいと思っています。ですから、私は別のアプローチ、すなわち、検索ビューとカスタムリストビューを含むレイアウトをダイアログに設定するのではなく、マルチチェックダイアログ内でこの方法で修正しようとしています（ ）。このコードは ArrayIndexOutOfBoundsExceptionをスローします。チェックリスト を変更しようとすると、checkedColours配列とbuildingNames配列の項目の数が最初の長さと異なるためです。このように検索ビューを機能させることはできますか？この方法がうまくいかない場合は、もう1つの方法 に従うようにヒントを提案してください（searchviewとカスタムlistviewのレイアウトをダイアログに使用する）。これに関する助けをいただければ幸いです。前もって感謝します。

MultiSelectSpinnerれスピナーとSEARCH /フィルタ項目から複数の項目を選択することができますスピナーアイテムから。
