如何在不切断单词的情况下自动将行分成多行？每行的长度约为4个字？我有很多句子，所以我不能使用\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

希望很快能对您有所帮助。谢谢！

最佳答案

我可以想象，尽管您不确定我是否正在考虑所有可能的情况，但还是根据您的意见，提出了一种方法，可以在想当然而又不直接依赖“ \ n “ 将会...

    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，您可能会考虑使用类似这样的方法，它可以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，并导致您要避免的情况...

    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：
我照你的要求做了。这就是我从MAX选项中得到的...

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

这就是我经常得到的...

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，但是我会说我对答案很感兴趣。您已经标记了Android，并且我和我俩都知道System.out.println()在那种环境下是禁忌，至少如果您希望看到任何结果的话。对于那个很抱歉。
