Android RecycleView 实现左滑上下分层示例代码（自定义功能）

Constructor constructor2 = mClazz.getConstructor(View.class);
holder = constructor2.newInstance(v);

 Constructor constructor = ViewHolderClass.SlideViewHolder.class.getConstructor(View.class);
   holder = constructor.newInstance(v);

   View contentView = View.inflate(parent.getContext(), mLayoutId, null);

   ViewGroup.LayoutParams params = new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup
     .LayoutParams.WRAP_CONTENT);

   ((ViewHolderClass.SlideViewHolder) holder).mRlSlidContent.addView(contentView, params);

   Constructor constructor2 = mClazz.getConstructor(View.class);
   holder = constructor2.newInstance(v);

   ((ViewHolderClass.SlideViewHolder) holder).mRlSlidContent.getLayoutParams().width = getScreenWidth(parent.getContext());
