二、问题原因：据说是这是Android-support-v7包中的bug。

三、解决方案：捕获这个异常，如让我们的程序崩溃；重写Wrapper，然后用setLayoutManager设置。

public class WrapContentLinearLayoutManager extends LinearLayoutManager {

public WrapContentLinearLayoutManager(Context context) {

super(context);

}

public WrapContentLinearLayoutManager(Context context, int orientation, boolean reverseLayout) {

super(context, orientation, reverseLayout);

}

public WrapContentLinearLayoutManager(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) {

super(context, attrs, defStyleAttr, defStyleRes);

}

@Override

public void onLayoutChildren(RecyclerView.Recycler recycler, RecyclerView.State state) {

try {

super.onLayoutChildren(recycler, state);

} catch (IndexOutOfBoundsException e) {

e.printStackTrace();

}

}

}

mRecyclerView.setLayoutManager(new WrapContentLinearLayoutManager(this, LinearLayoutManager.VERTICAL, false));
