如果纵横字谜的大小是maxSize，并且任何单词的长度都存储在wordLength中，那么您可以使用如下随机方法
int maxSize=20；
int字长=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);
如果行和列已经存在，您可以存储行和列并生成新的行和列。好的，首先祝贺您获得了好的JAVA代码，但您必须记住，作为操作系统的Android与JAVA不同。首先，作为“main”类的所有类都不使用公共静态void main（String[]args） 公共静态void main（字符串args）public class Crosswords extends Activity{
