RecyclerViewでConcurrentModificationExceptionが表示され、APIでのみ23 & 26、これを回避するにはどうすればよいですか？ これは私のRecyclerViewセットアップです：RecyclerViewエラーConcurrentModificationExceptionのみAPI 23＆API 26
private void setUpRecyclerView() {
int maxIndex = 0;
if (game.size() < 3) {
maxIndex = game.size();
} else if (game.size() >= 3) {
maxIndex = 3;
}
recyclerView = findViewById(R.id.home_recycler_view);
adapter = new GameCardListMiniAdapter(this, game.subList(0, maxIndex));
recyclerView.setAdapter(adapter);
LinearLayoutManager linearLayoutManager = new LinearLayoutManager(ActivityHome.this);
linearLayoutManager.setOrientation(LinearLayoutManager.HORIZONTAL);
recyclerView.setHasFixedSize(true);
recyclerView.setLayoutManager(linearLayoutManager);
recyclerView.setItemAnimator(new DefaultItemAnimator());
}
私はgameからのデータを操作した後、私は15点のすべての作品APIまでのAPIの残りの部分ではなく、唯一前述上記のAPIで、recyclerView.swapAdapter(adapter, true);を呼び出すとエラーが出ますちょうど良い。 これは、API 23のためのスタックトレースです：

これは、API 26のためである：

は、代わりにSubListのforループと、それは外game.SubListを作成する作業作ってみましたクラッシュしませんでしたが、swapAdapterは呼び出されていませんでした。そして、最も奇妙なことは、私の電話機ではすばらしいことです。クラッシュや予想される動作です。
私は本当に、本当に光を感謝します。 よろしくNe0R @銅
あなたの提案をありがとうが、私は同じエラーが表示されますがまだ動作しません。 – Racu
