Description

尝试了几次,没有添加Header和其它Adapter无异,当addHeaderView后出现异常,数组越界。
java.lang.ArrayIndexOutOfBoundsException: length=0; index=-1 at java.util.ArrayList.get(ArrayList.java:439) at com.chad.library.adapter.base.BaseQuickAdapter.getItem(BaseQuickAdapter.java:604) at com.chad.library.adapter.base.BaseQuickAdapter.onBindViewHolder(BaseQuickAdapter.java:931) at com.chad.library.adapter.base.BaseQuickAdapter.onBindViewHolder(BaseQuickAdapter.java:68) at androidx.recyclerview.widget.RecyclerView$Adapter.onBindViewHolder(RecyclerView.java:7254) at androidx.recyclerview.widget.RecyclerView$Adapter.bindViewHolder(RecyclerView.java:7337) at androidx.recyclerview.widget.NestedAdapterWrapper.onBindViewHolder(NestedAdapterWrapper.java:157) at androidx.recyclerview.widget.ConcatAdapterController.onBindViewHolder(ConcatAdapterController.java:368) at androidx.recyclerview.widget.ConcatAdapter.onBindViewHolder(ConcatAdapter.java:188)

Research direction

Start with BaseQuickAdapter.getItem and onBindViewHolder, then reproduce the reported ArrayIndexOutOfBoundsException when addHeaderView is used with AndroidX ConcatAdapter. Compare the adapter position handling shown in the stack trace and verify that the same setup binds without an exception once fixed.
