RecyclerView实现侧滑拖拽功能

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

  * 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;

   *
   * @param context 上下文
   */
