关于recyclerView上下滑动时的崩溃问题

昨天遇到一个神奇并且很难缠的bug……

RecyclerView上下滑动的时候崩溃，崩溃信息如下：

java.lang.IndexOutOfBoundsException
Inconsistency detected. Invalid item position 16(offset:16).state:64
android.support.v7.widget.RecyclerView$Recycler.getViewForPosition(RecyclerView.java:4957)

搜遍了Google，百度，github，stackoverflow……都没有解决，算了自己动手丰衣足食。经过两天研究这么解决了：

/**
* 去除动画防止，防止出现recyclerView的bug
* Created by zhanglin on 2016/11/3.

public class MyLinearLayoutManager extends LinearLayoutManager {
public MyLinearLayoutManager(Context context) {
super(context);
}

@Override
public boolean supportsPredictiveItemAnimations() {
return false;
}

public void onLayoutChildren(RecyclerView.Recycler recycler, RecyclerView.State state) {
try {
super.onLayoutChildren(recycler, state);
} catch (IndexOutOfBoundsException e) {
e.printStackTrace();

}
}

@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;
}
}

Java中如下：

MyLinearLayoutManager myLinearLayoutManager = new MyLinearLayoutManager (mContext);
recyclerView.setLayoutManager(myLinearLayoutManager );

解决了，好开心哈哈哈
