java - 我怎样才能为我的结构获得无限数量的项目

Question

  Article article = null;
  Article article2 = null;
  Article article3 = null;
  if (position == 0)
  {
  article = getItem(0);
  article2 = getItem(1);
  article3 = getItem(2);
  }
  else if (position == 1)
  {
  article = getItem(3);
  article2 = getItem(4);
  article3 = getItem(5);
  }
  else if (position == 2)
  {
      article = getItem(6);
      article2 = getItem(7);
      article3 = getItem(8);
  }

我需要像这样获取我的项目列表，但直到第 90 个项目(位置)我才能做到这一点。 我怎样才能无限次地编写这些代码。

Answer 1

I need to get my item list like this, but i can't do that until 90th item(position). How can i write these codes for infinite times.

你可以这样做:

article = getItem((position * 3));
article2 = getItem((position * 3) + 1);
article3 = getItem((position * 3) + 2);

这是一个简单的解决方案，并且会给你带来好处。
