我是靠谱客的博主饱满奇异果，最近开发中收集的这篇文章主要介绍RecyclerView实现侧滑拖拽功能，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

本文实例为大家分享了RecyclerView实现侧滑拖拽功能的具体代码，供大家参考，具体内容如下

准备

ItemDragListener

package slideslipdrag;

import android.support.v7.widget.RecyclerView;

/**
 * Created on 2018/7/22.
 *
 * @desc ItemDragListener
 */
public interface ItemDragListener {
 /**
  * 拖拽
  *
  * @param viewHolder viewHolder
  */
 void onStartDrag(RecyclerView.ViewHolder viewHolder);
}

ItemTouchHelperAdapter

package slideslipdrag;

/**
 * @decs: ItemTouchHelperAdapter
 * @date: 2018/7/22 13:23
 * @version: v 1.0
 */
public interface ItemTouchHelperAdapter {
 /**
  * 移动
  *
  * @param fromPosition 起始位
  * @param toPosition 终止位
  */
 void onItemMove(int fromPosition, int toPosition);

 /**
  * 侧滑结束
  *
  * @param position 位置
  */
 void onItemSlideSlipEnd(int position);
}

ItemTouchHelperViewHolder

package slideslipdrag;

import android.content.Context;

/**
 * @decs: ItemTouchHelperViewHolder
 * @date: 2018/7/22 13:24
 * @version: v 1.0
 */
public interface ItemTouchHelperViewHolder {
  /**
   * 侧滑开始
   *
   * @param context 上下文
   */
  void onItemSlideSlipStart(Context context);

  /**
   * 侧滑停止
   *
   * @param context 上下文
   */
  void onItemSlideSlipStop(Context context);
}
