Question

这可能看起来像是一个重复的问题，但事实并非如此！

我在RecyclerView上遇到这种罕见的崩溃

java.lang.IndexOutOfBoundsException: 
Inconsistency detected. 
Invalid item position 1(offset:1).state:4 at android.support.v7.widget.RecyclerView$Recycler.getViewForPosition(RecyclerView.java:5014).

我很确定数据更改后我没有错过任何关于适配器的通知！。

除了崩溃之外，我无法理解的一件事是我使用的是android.support.v7.widget.RecyclerView，崩溃是在那个java文件中的第5014行

我发生崩溃的RecyclerView.java代码

 if (offsetPosition < 0 || offsetPosition >= mAdapter.getItemCount()) {
            throw new IndexOutOfBoundsException("Inconsistency detected. Invalid item "
                    + "position " + position + "(offset:" + offsetPosition + ")."
                    + "state:" + mState.getItemCount());
        }

因此要么崩溃

offsetPosition < 0

或

offsetPosition >= mAdapter.getItemCount()

从崩溃日志中清楚地看出，我的offsetPosition是1，所以

offsetPosition >= mAdapter.getItemCount()

必须是真的!!但是在我的适配器中，我像这样实现了getItemCount

@Override
public int getItemCount() {
    return list.size() + 3;
}

所以至少getItemCount应该返回3，所以第二个陈述也不可能是真的。
