如何在不截断单词的情况下自动将一行分成多行？每行的长度大约是 4 个单词？我有很多句子，因此我无法使用 \n

例如:

If I were you I would go to the cinema with her

变成:

If I were you 
I would go to 
the cinema with her

希望尽快看到您的帮助。谢谢!

我想，根据你所输入的内容，尽管我不确定你是否考虑了所有可能的情况，一种在采取一些措施的同时获得你正在寻找的具体答案的方法当然，不直接依赖“\n”将是......

    String s = "If I were you I would go to the cinema with her";
    String[] strings = s.split(" ");
    for(int i = 0; i < strings.length; ++i) {
        if(i % 4 == 0) {
            System.out.println();
        }
        System.out.print(strings[i] + " ");
    }

或者，您可能会考虑这样的事情，它将处理文本字段的最大宽度，而不是一定数量的单词，因为某些单词可能很长并导致您试图避免的情况...

    int MAX = 20;
    int length = 0;
    String s = "If I were you I would go to the cinema with her.";
    String[] strings = s.split(" ");
    for(int i = 0; i < strings.length; ++i) {
        if((length + strings[i].length()) > MAX ) {
            System.out.println();
            length = 0;
        }
        System.out.print(strings[i] + " ");
        length += strings[i].length() + 1;
    }

编辑:

我按照你的要求做了。这是我从 MAX 选项中得到的结果...

If I were you I 
would go to the 
cinema with her and 
abc xyz 

这就是我常规得到的...

If I were you 
I would go to 
the cinema with her 
and abc xyz 

不知道那里发生了什么，但我会说我的回答太冒险了。您已经标记了 Android，并且您和我都知道 System.out.println() 在该环境中是禁忌，至少如果您希望看到任何结果的话。对此感到抱歉。
