嗨，我在我的应用程序上收到 Fabric 的错误报告-> StaggeredGridLayoutManager calculateCachedStart() 方法上的 IndexOutOfBoundsException

我的应用程序中有很多使用 StaggeredGridLayoutManager。有什么想法可以解决此错误或跟踪我的应用程序中导致此错误的原因吗？

使用编译“com.android.support:recyclerview-v7:25.2.0

如果您RecyclerView在 a 中Fragment并且您Fragment在中ViewPager，并且您没有设置viewpager.setOffscreenPageLimit(MAX_ITEM_SIZE)，则此崩溃有时会意外发生。

我正在遭受同样的崩溃。我无法重现它，也不知道为什么会发生这种情况。但是在我设置了离屏页面限制后，这个崩溃就消失了。

希望它有所帮助。

它是 StaggeredGridLayoutManager.java 的一部分

  /**
     * Checks for gaps in the UI that may be caused by adapter changes.
     * <p>
     * When a full span item is laid out in reverse direction, it sets a flag which we check when
     * scroll is stopped (or re-layout happens) and re-layout after first valid item.
     */
    boolean checkForGaps() {
        if (getChildCount() == 0 || mGapStrategy == GAP_HANDLING_NONE || !isAttachedToWindow()) {
            return false;
        }
        final int minPos, maxPos;
        if (mShouldReverseLayout) {
            minPos = getLastChildPosition();
            maxPos = getFirstChildPosition();
        ....

作为解决方法，我们可以阻止StaggeredGridLayoutmanager.hasGapsTofix()调用（这是导致此崩溃的原因）。

staggeredGridLayoutmanager.gapStrategy = StaggeredGridLayoutManager.GAP_HANDLING_NONE

但是这个选项会禁用意外的间隙处理。

我有类似的问题。在我的情况下，我有一个“父级”RecyclerView，其中一个项目有自己的“子级”RecyclerView 和 StaggeredGridLayoutManager。当连接到此项目的 ViewHolder 被回收时发生崩溃。在这个 ViewHolder 上设置RecyclerView.ViewHolder.setIsRecyclable(false)为我解决了这个问题
