后来我重新看了下，又没有出现anr。出现了下面问题：
1.空指针crash
2.上下快速滑动会卡顿，布局会重叠
java.lang.NullPointerException: Attempt to read from field 'int android.graphics.Rect.bottom' on a null object reference at com.test.toastdemo.FlowLayoutManager.fill(FlowLayoutManager.java:191)
at com.test.toastdemo.FlowLayoutManager.scrollVerticallyBy(FlowLayoutManager.java:241)
at android.support.v7.widget.RecyclerView$ViewFlinger.run(RecyclerView.java:4680)

代码片段：
RecyclerView.setLayoutManager(new FlowLayoutManager());
RecyclerView.setAdapter(new RecycleViewAdapter(this, Data.foods()));
public static List foods(){
List foods =new ArrayList<>();
Data food = null;
for (int i = 0 ; i < 10000 ; i++){
food = new Data("recycle"+"("+i+")");
foods.add(food);
}
return foods;
}
