我有这个字符串:“这是我的很长的字符串，无法容纳在一行中” 我需要将其分成多行，以便它适合我需要的地方。
假设每行只能容纳大约 15 个字母，那么它应该如下所示:
"This is my very"
"long String"
"that wont fit"
"on one line"
我想把它分成 List<String>所以我可以做
for(String s : lines) draw(s,x,y);
任何有关如何执行此操作的帮助将不胜感激!
我渲染文本的方式是使用 Graphics.drawString()
这是我迄今为止尝试过的(我知道这很糟糕)
String diaText = "This is my very long String that wont fit on one line";
String[] txt = diaText.trim().split(" ");
int max = 23;
List<String> lines = new ArrayList<String>();
String s1 = "";
if (!(diaText.length() > max)) {
lines.add(diaText);
} else {
for (int i = 0; i < txt.length; i++) {
String ns = s1 += txt[i] + " ";
if (ns.length() < 23) {
lines.add(s1);
s1 = "";
} else {
s1 += txt[i] + "";
}
}
}
int yo = 0;
for (String s : lines) {
Font.draw(s, screen, 70, 15 + yo, Color.get(-1, 555, 555,555));
yo += 10;
}

关于java - 如果字符串太长，则将字符串拆分为 List<String>，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/9005804/
