android 快速实现 recyclerview 的所有item 都执行动画

1.在adapter 里面重写onViewAttachedToWindow 和 onViewDetachedFromWindow 两个方法

package com.example.widget;import android.view.ViewGroup;
import android.view.animation.Animation;
import android.view.animation.LinearInterpolator;
import android.view.animation.RotateAnimation;import androidx.annotation.NonNull;
import androidx.recyclerview.widget.RecyclerView;public class A extends RecyclerView.Adapter {@NonNull@Overridepublic RecyclerView.ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {return null;}@Overridepublic void onBindViewHolder(@NonNull RecyclerView.ViewHolder holder, int position) {}@Overridepublic int getItemCount() {return 0;}//view依附窗口上时@Overridepublic void onViewAttachedToWindow(@NonNull RecyclerView.ViewHolder holder) {//仿桌面删除app 的抖动动画RotateAnimation animation = new RotateAnimation(-2, 2, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f);animation.setDuration(100);animation.setRepeatMode(Animation.REVERSE);animation.setRepeatCount(Animation.INFINITE);animation.setInterpolator(new LinearInterpolator());holder.itemView.startAnimation(animation);//itemView执行动画//holder.ivIcon.startAnimation(animation);//执行子view动画super.onViewAttachedToWindow(holder);}//view被移除时@Overridepublic void onViewDetachedFromWindow(@NonNull RecyclerView.ViewHolder holder) {if (holder.itemView.getAnimation() != null) {holder.itemView.clearAnimation();//清除动画}super.onViewDetachedFromWindow(holder);}
}
