关于recylerview的OnTouchListener方法 遇到一点问题

直接贴代码吧 这是在Adapter里面添加接口 然后再类里面调用的代码

@Override
public void onBindViewHolder(final ViewHolder viewHolder, final int position) {
viewHolder.tv.setText(mDatas.get(position));

    if (mOnItemClickLitener != null) {
        viewHolder.itemView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                int pos = viewHolder.getLayoutPosition();
                mOnItemClickLitener.onItemClick(viewHolder.itemView, pos);
            }
        });
    }
    if (onItemTouchListener != null) {
        viewHolder.itemView.setOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {
                int pos = viewHolder.getLayoutPosition();
                onItemTouchListener.onItemTouch(viewHolder.itemView, pos);
                return false;
            }
        });
    }









            Adapter.setOnItemTouchListener(new SearchRecyclerAdapter.OnItemTouchListener() {
        @Override
        public void onItemTouch(View view, int position) {
            if (view.isPressed()){
                System.out.println("按下");
            }else {
                System.out.println("抬起");
            }
        }
    });

运行的结果是按下打印抬起 抬起无打印 想请教一下要怎么更正呢？？
