下の行feedItems.adAll(adItems)のすぐ下に、いくつかのコード行がコメントされています。この例外が発生するたびに、私はfeedItemsリストが空であることを証明できます。ここで2つのビュータイプを持つRecyclerAdapterのIndexOutOfBoundsException
は私RecyclerAdapterです：

この原因は何？ VMがシャットダウンし、あなたが速すぎてフィードをスクロールするたびに次の例外が発生します。

はEDIT
例外はアイテムの位置が5である場合に発生する停止しますが、ない10または15、または私が試した他の番号：
// Differentiate between feedItem views and nativeAds
@Override
public int getItemViewType(int position) {
int viewType = 1;
if ((position % 5 == 0) && position != 1) viewType = 2;
return viewType;
}
私はこれがなぜ起こっているのか分かりません。
は、私はちょうど私のコンテキストでこれを解決する方法を思ったんだけど、意味があります。 – santafebound
私はあなたのコードを完全に理解することはできませんが、クラッシュする時間、何がその瞬間に起こるのか、何を尋ねるのか、それが何であるかを考えるだけです。 –
adItems.isEmpty（）がtrueのときにクラッシュします。つまり、読み込み中に配列にオブジェクトが存在しない場合です。 – santafebound
