Android：StaggeredGridLayoutManagerのArithmeticException

Question

私のアプリはほとんどのアンドロイド版でうまく動作します。しかし、Crashlyticsやいくつかのデバイスでは、このクラッシュがあります。 "java.lang.ArithmeticException：0で割る"。 Android 4.xではほとんど（常にではないにしても）。

私はRecyclerView（SuperRecyclerView）にStaggeredGridLayoutManagerを持っています。

私はそうあなたがそう、私は質問を更新することができます必要なものは何でも私に聞いてください、この問題にアプローチするために必要とされる情報の種類を知りません。

Answer 1

も見ましたが、Android 5と7でも同様でした。私はコードをチェックし、明らかにmSpanCountが0のときクラッシュします。GridLayoutManagerとは異なり、StaggeredGridLayoutManagerのsetSpanCountはそれが1以上かどうかをチェックせず、後でクラッシュします。 私の場合、スパン数は0になりました。これは画面サイズに依存するため、まれに0と思われます。
