Android 使用 Java 的填字游戏算法
Crossword algorithm for Android using Java
我正在研究填字游戏算法来开发一个单词应用程序。在进行大量谷歌搜索或在 Whosebug 上搜索之后，我能够达到这一点。但是我无法理解 Java 中算法的正确实现。下面是我用的class

public static void main(String[] args) {

}
}
正如您在 Main 方法中看到的那样，我在添加单词的同时还给出了行号和列号以放置 c.addWordv("Safe",8, 5); 其中 8 和 5 是列号。
现在问题是我如何实现填字游戏算法，它只取单词并将它们随机放在板上而不取行号和列号。
提前致谢
编辑：
我想以不必放弃行数和列数的方式修改此 class 算法..
//伪代码
如果填字游戏的大小是maxSize，并且任何单词的长度都存储在wordLength中，那么你可以使用如下随机方法
int 最大尺寸=20；
int wordLength=4;
Random random =new Random();
int r,c;
//for horizontal
r=random.nextInt(maxSize-wordLength);
c=random.nextInt(maxSize);
//for vertical
r=random.nextInt(maxSize);
c=random.nextInt(maxSize-wordLength);
您可以存储行和列并生成新的（如果已经存在）。
好的，首先恭喜你获得了好的 JAVA 代码，但你必须记住 Android 作为 OS 不同于 Java。首先，所有'main'classes的classes不使用public static void main(String[] args)。他们扩展 Activity。 public static void main(string args) 对启动您的应用无效，这意味着代码永远不会 运行!

因为你的代码在初始化方面是错误的，以后真的很烦你。你必须记住，创建一个 java 项目是不够的，因为它永远不会 运行 在 Android 上。所以这里有一些提醒：
- 类 像这样（不同的屏幕）扩展 Activity 并使用 onCreate 设置屏幕的内容
- 通过如下所示创建更多 activity 将导致计算器溢出错误（new class -> oncreate -> new class -> onCreate -> crash）
- 自定义 canvas 扩展了 SurfaceView（canvas 是您可以借鉴的东西）
- 与 Java 一起使用的初始化不适用于 android。您需要一个 Android 清单并声明活动、权限
- 您需要一个 Android 项目和 Android SDK（我推荐 Android Studio）
另外，上面的代码还没有准备好部署，但它初始化（有错误）作为一个例子。我强烈建议您服用一些 Android tutorials，因为 Android 与 'regular' Java 非常不同。上面的代码是为了帮助您入门

因为你的代码在初始化方面是错误的，以后真的很烦你。你必须记住，创建一个 java 项目是不够的，因为它永远不会 运行 在 Android 上。所以这里有一些提醒：
- 类 像这样（不同的屏幕）扩展 Activity 并使用 onCreate 设置屏幕的内容
- 通过如下所示创建更多 activity 将导致计算器溢出错误（new class -> oncreate -> new class -> onCreate -> crash）
- 自定义 canvas 扩展了 SurfaceView（canvas 是您可以借鉴的东西）
- 与 Java 一起使用的初始化不适用于 android。您需要一个 Android 清单并声明活动、权限
- 您需要一个 Android 项目和 Android SDK（我推荐 Android Studio）
另外，上面的代码还没有准备好部署，但它初始化（有错误）作为一个例子。我强烈建议您服用一些 Android tutorials，因为 Android 与 'regular' Java 非常不同。上面的代码是为了帮助您入门
