  • Android成語縱橫1.3版的速度问题

    有用户反映成語縱橫1.3版似乎变慢了。在1.3版我主要引入了即时反馈，即在一个成语所有的字被找出后，马上自动改变成语的背景色。另一个改动是利用Android的GestureDector检测单点触击和滑动手指。这两项改动都可能影响速度。 在下一版，我将在设置中增加一个选项，允许用户选择是否提供即时反馈。同时改进GestureDector的用法。 在新版推出之前，请尽量通过滑动手指一次选择多个字。这样会大大提高游戏的流畅性。这也同样适合于古诗纵横游戏。 More.

  • Android App古诗纵横

    刚刚发布了古诗纵横（繁体版和简体版）。 古诗纵横采用与成语纵横相同的填字游戏生成引擎，从106首脍炙人口的古诗中随机生成“找诗句”或“填字”游戏。在游戏过程中，可参考提示。 在玩找诗句游戏时，可单选某一个字，或通过滑动手指一次选择某诗句的所有的字。在一个诗句的所有的字都被选出后，该诗句会自动变色，表示该诗句已被找出。 在玩填字游戏时，沿着某一个诗句的方向滑动手指，能自动调出该诗句的提示。 你可以读任意一首古诗、或某作者的诗。你还可以查找诗句。每首诗的关键字都有注释。 More.
