前言：

本篇讲解了RecyclerView关于通知列表刷新的常用的notify方法。和RecyclerView动画的简单详解。

首先看下效果图

1、页面对应的xml代码如下：

presenter.onClick(view)}"android:text="重置"app:layout_constraintStart_toStartOf="parent"app:layout_constraintTop_toTopOf="parent" />presenter.onClick(view)}"android:text="全部刷新"app:layout_constraintStart_toEndOf="@id/btn_reset"app:layout_constraintTop_toTopOf="parent" />presenter.onClick(view)}"android:text="刷新第2条"app:layout_constraintStart_toEndOf="@id/btn_refresh_all"app:layout_constraintTop_toTopOf="parent" />presenter.onClick(view)}"android:text="刷新第2,3,4条"app:layout_constraintStart_toEndOf="@id/btn_refresh_2"app:layout_constraintTop_toTopOf="parent" />presenter.onClick(view)}"android:text="局部刷新第2条"app:layout_constraintStart_toStartOf="parent"app:layout_constraintTop_toBottomOf="@id/btn_reset" />presenter.onClick(view)}"android:text="局部刷新第2,3,4条"app:layout_constraintStart_toEndOf="@+id/btn_part_refresh_2"app:layout_constraintTop_toBottomOf="@id/btn_reset" />presenter.onClick(view)}"android:text="位置1插入一条"app:layout_constraintStart_toStartOf="parent"app:layout_constraintTop_toBottomOf="@id/btn_part_refresh_234" />presenter.onClick(view)}"android:text="位置3插入两条"app:layout_constraintStart_toEndOf="@id/btn_insert_1_1"app:layout_constraintTop_toBottomOf="@id/btn_part_refresh_234" />presenter.onClick(view)}"android:text="2移到4(都指的是索引)"app:layout_constraintStart_toEndOf="@id/btn_insert_3_2"app:layout_constraintTop_toBottomOf="@id/btn_part_refresh_234" />presenter.onClick(view)}"android:text="删除第2条"app:layout_constraintStart_toStartOf="parent"app:layout_constraintTop_toBottomOf="@id/btn_move_2_4" />presenter.onClick(view)}"android:text="删除第2,3,4条"app:layout_constraintStart_toEndOf="@id/btn_remove_2"app:layout_constraintTop_toBottomOf="@id/btn_move_2_4" />

2、对应的适配器代码如下

/*** @Author: ly* @Date: 2023/3/9* @Description: 适配器*/
public class NotifyDataAdapter extends RecyclerView.Adapter {private List notifyModels = new ArrayList<>();public NotifyDataAdapter(List notifyModels) {this.notifyModels = notifyModels;}@NonNull@Overridepublic NotifyDataViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {ItemNotifyDataBinding binding = DataBindingUtil.inflate(LayoutInflater.from(parent.getContext()), R.layout.item_notify_data, parent, false);Log.i("TAG", "onCreateViewHolder: ");return new NotifyDataViewHolder(binding);}@Overridepublic void onBindViewHolder(@NonNull NotifyDataViewHolder holder, int position) {Log.i("TAG", "onBindViewHolder:两个参数 " + position);holder.bindData(position);}@Overridepublic void onBindViewHolder(@NonNull NotifyDataViewHolder holder, int position, @NonNull List
