在使用RecyclerView时，有时候出现类似下方的这种错误：
java.lang.IndexOutOfBoundsException: Inconsistency detected. Invalid item position 0(offset:0).state:60 android.support.v7.widget.RecyclerView{1dee303 VFED..... .F......

刚开始遇见你会很奇怪，这种错误不会提示你任何一行代码有问题，但它就是会让程序crash掉，使用 RecyclerView 加SwipeRefreshLayout下拉刷新的时候，如果绑定的 List 对象在更新数据之前进行了 clear，而这时用户紧接着迅速上滑 RecyclerView，就会造成崩溃，而且异常不会报到我们的代码上，属于RecyclerView内部错误。这就是当 clear 了 list 之后，这时迅速上滑，此时新数据还没到来，就会导致 RecyclerView 要更新加载下面的 Item 时候，找不到数据源了，造成 crash。这种方法该如何解决，我们可以使用自定义的布局，然后将其加载到RecyclerView 中，手动去捕获这个异常信息，从而不让程序crash,
public class RecyclerViewNoBugLinearLayoutManagerextends LinearLayoutManager {
public RecyclerViewNoBugLinearLayoutManager(Context context) {
super(context);
}
public RecyclerViewNoBugLinearLayoutManager(Context context, int orientation, boolean reverseLayout) {
super( context, orientation, reverseLayout );
}
public RecyclerViewNoBugLinearLayoutManager(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) {
super( context, attrs, defStyleAttr, defStyleRes );
}
@Override
public void onLayoutChildren(RecyclerView.Recycler recycler, RecyclerView.State state) {
try {
//try catch一下
super.onLayoutChildren( recycler, state );
}catch (IndexOutOfBoundsException e) {
e.printStackTrace();
}
}
@Override
public boolean supportsPredictiveItemAnimations() {
return false;
}
@Override
public int scrollVerticallyBy(int dy, RecyclerView.Recycler recycler, RecyclerView.State state) {
try {
return super.scrollVerticallyBy(dy, recycler, state);
}catch (Exception e) {
e.printStackTrace();
}
return 0;
}
}
