内部Adapter 核心代码

  holder.btn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Toast.makeText(con, "删除", Toast.LENGTH_SHORT).show();
                lisner.onCilck(position);
            }
        });

        rv2.setOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {
                return false;
            }
        });
