本文介绍了RecyclerView和java.lang.IndexOutOfBoundsException:检测到不一致.三星设备中无效的视图支架适配器positionViewHolder的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有一个回收站视图，该视图在三星以外的所有设备上均能完美运行.在三星上，我得到了
I have a recycler view that works perfectly on all devices except Samsung. On Samsung, I'm get

我该如何解决?
推荐答案
此问题是由RecyclerView在不同线程中修改数据引起的.最好的方法是检查所有数据访问.一种解决方法是包装LinearLayoutManager.
This problem is caused by RecyclerView Data modified in different thread. The best way is checking all data access. And a workaround is wrapping LinearLayoutManager.
RecyclerView中实际上存在一个错误，并且支持23.1.1仍未修复.
There was actually a bug in RecyclerView and the support 23.1.1 still not fixed.
要解决此问题，请注意回溯堆栈，如果我们可以在某个类之一中捕获此Exception，则可能会跳过此崩溃.对我来说，我创建了LinearLayoutManagerWrapper并覆盖了onLayoutChildren:
For a workaround, notice that backtrace stacks, if we can catch this Exception in one of some class it may skip this crash. For me, I create a LinearLayoutManagerWrapper and override the onLayoutChildren:
public class WrapContentLinearLayoutManager extends LinearLayoutManager {
//... constructor
@Override
public void onLayoutChildren(RecyclerView.Recycler recycler, RecyclerView.State state) {
try {
super.onLayoutChildren(recycler, state);
} catch (IndexOutOfBoundsException e) {
Log.e("TAG", "meet a IOOBE in RecyclerView");
}
}
}
然后将其设置为RecyclerView:
RecyclerView recyclerView = (RecyclerView)findViewById(R.id.recycler_view);
recyclerView.setLayoutManager(new WrapContentLinearLayoutManager(activity, LinearLayoutManager.HORIZONTAL, false));
实际上捕获了此异常，并且似乎还没有任何副作用.
Actually catch this exception, and seems no any side-effect yet.
此外，如果使用GridLayoutManager或StaggeredGridLayoutManager，则必须为其创建包装.
Also, if you use GridLayoutManager or StaggeredGridLayoutManager you must create a wrapper for it.
注意:RecyclerView可能处于错误的内部状态.
Notice: The RecyclerView may be in a wrong internal state.
