在 2 行上显示文本视图（任意字符串长度）

Question

我有一个字符串数组如下：[“你好”，“说再见”，“我是开发人员”，“Java是一种面向对象的语言”，“Web应用程序编程，...]

如果字符串超过一个单词，我想在 TextView 上显示两行，并且两行之间的字符数差异最小。

例如：“Web应用程序编程”应该是“Web应用程序编程”，而不是“Web应用程序编程”。

有什么办法可以做到这一点吗？

这应该适合您的问题：private String wrapText(String in) {&nbsp; &nbsp; String r;&nbsp; &nbsp; if(in.contains(" ")) {&nbsp; &nbsp; &nbsp; &nbsp; int middle = in.length() / 2;&nbsp; &nbsp; &nbsp; &nbsp; int before = getSpaceBeforeIndex(in, middle);&nbsp; &nbsp; &nbsp; &nbsp; int after = getSpaceAfterIndex(in, middle);&nbsp; &nbsp; &nbsp; &nbsp; int rightOne;&nbsp; &nbsp; &nbsp; &nbsp; if(before == -1) {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; rightOne = after;&nbsp; &nbsp; &nbsp; &nbsp; } else if(after == -1) {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; rightOne = before;&nbsp; &nbsp; &nbsp; &nbsp; } else {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; rightOne = (middle - before) < (after - middle)? before : after;&nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; &nbsp; &nbsp; r = in.substring(0, rightOne) + "\n" + in.substring(rightOne);&nbsp; &nbsp; } else {&nbsp; &nbsp; &nbsp; &nbsp; r = in;&nbsp; &nbsp; }&nbsp; &nbsp; return r;}private static int getSpaceBeforeIndex(String in, int index) {&nbsp; &nbsp; String cut = in.substring(0, index);&nbsp; &nbsp; int firstSpace = cut.lastIndexOf(" ");&nbsp; &nbsp; return firstSpace;}private static int getSpaceAfterIndex(String in, int index) {&nbsp; &nbsp; int nextSpace = in.indexOf(" ", index);&nbsp; &nbsp; return nextSpace;}
