Android ViewGroup.dispatchCollectViewAttributes NPE

奔跑的猴子我得到了这次撞车，看起来McChildren[i]无效，这应该从未发生过。还是有什么可能的原因

以下是视图组中发生NPE的位置：

@覆盖
void dispatchCollectViewAttributes（AttachInfo AttachInfo，int可见性）{
if（（可见性和可见性\u掩码）=可见）{
super.dispatchCollectViewAttributes（附件信息、可见性）；
最终整数计数=McChildrenCount；
最终视图[]儿童=儿童；
for（int i=0；i

请提供发生错误的正文的代码片段。运行monkey:o通常它们会跳转：D@Ivan您在错误日志跟踪中没有看到任何类/包？@Charuක 这只猴子跑得很多；）@NishanKhadka上面的日志是我所有的，我不知道导致错误的代码在哪里。我刚刚在上面的viewgroup中发布了dispatchCollectViewAttributes方法，不知它是否提醒了您什么

@Override
void dispatchCollectViewAttributes(AttachInfo attachInfo, int visibility) {
    if ((visibility & VISIBILITY_MASK) == VISIBLE) {
        super.dispatchCollectViewAttributes(attachInfo, visibility);
        final int count = mChildrenCount;
        final View[] children = mChildren;
        for (int i = 0; i < count; i++) {
            final View child = children[i];
            child.dispatchCollectViewAttributes(attachInfo,
                    visibility | (child.mViewFlags&VISIBILITY_MASK));
        }
    }
}
