嗨我在我的应用上收到Fabric的错误报告 - ＆gt; StaggeredGridLayoutManager calculateCachedStart（）方法的IndexOutOfBoundsException
我的应用程序上有很多用法StaggeredGridLayoutManager。 有没有想法修复此错误或跟踪我的应用程序中哪一个导致此错误？
使用compile＆＃34; com.android.support：recyclerview-v7：25.2.0

答案 0 :(得分：0)
如果您的RecyclerView在Fragment中，而您的Fragment在ViewPager中，而您没有设置viewpager.setOffscreenPageLimit(MAX_ITEM_SIZE)，则崩溃有时会发生意外发生。
我遭受了同样的崩溃。我无法复制它，也不知道为什么会到现在。但是，当我设置了屏幕外页面限制后，此崩溃便消失了。
希望有帮助。

我有类似的问题。在我的情况下，我有一个“父” RecyclerView，它的其中一个具有自己的带有StaggeredGridLayoutManager的“子” RecyclerView。回收与该项目连接的ViewHolder时发生崩溃。在此ViewHolder上设置RecyclerView.ViewHolder.setIsRecyclable(false)可以为我解决问题
答案 2 :(得分：0)
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();
....
作为一种解决方法，我们可以阻止 StaggeredGridLayoutmanager.hasGapsTofix() 调用（这就是这次崩溃的原因）。
staggeredGridLayoutmanager.gapStrategy = StaggeredGridLayoutManager.GAP_HANDLING_NONE
但此选项会禁用意外间隙处理。
