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<Data> foods(){ List<Data> foods =new ArrayList<>(); Data food = null; for (int i = 0 ; i < 10000 ; i++){ food = new Data("recycle"+"("+i+")"); foods.add(food); } return foods; }
