Android StaggedGridLayoutManager calculateCachedStart（）IndexOutfBoundsException

您好，我在我的应用程序->IndexOutfBoundsException上从Fabric获得了错误报告StaggedGridLayoutManager calculateCachedStart（）方法

在我的应用程序上有许多使用RidLayoutManager的功能。 有没有办法修复此错误或跟踪我的应用程序中导致此错误的原因

使用compile“com.android.support:recyclerview-v7:25.2.0

谢谢

如果您的

回收视图

位于

片段

中，而

片段

位于

查看页面

中，并且您没有设置

查看页面。setOffscreenPageLimit（最大项目大小）

，则此崩溃有时会意外发生

我也经历了同样的崩溃。我无法复制它，也不知道为什么会发生这种情况，直到现在。但在我设置了屏幕外页面限制后，这种崩溃消失了

希望能有所帮助。

我也有类似的问题。在我的例子中，我有一个“家长”回收视图，其中一个项目有自己的“孩子”“使用StaggedGridLayoutManager进行RecyclerView。回收连接到此项目的ViewHolder时发生崩溃。在此ViewHolder上进行设置为我解决了这个问题

它是StaggedGridLayoutManager.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();
        ....

但是此选项会禁用意外的间隙处理。

您是否解决了此问题？您已经初始化了

ArrayList

，但其中没有任何元素。您是如何解决此问题的？Thx.有人解决了这个问题吗？对我没有帮助：（这个对我有用。谢谢：）

staggeredGridLayoutmanager.gapStrategy = StaggeredGridLayoutManager.GAP_HANDLING_NONE
