java - Android SDK 或 Java 中是否有使用占位符替换部分字符串的实用程序？

Question

它会像这样工作

someUtility.replace ("Hello, my name is {1}.  What is your {2}?", "Mark", "name");

Answer 1

String.format("Hello, my name is %1$s.  What is your %2$s?", "Mark", "name");

或者如果您只按顺序使用每个一次:

String.format("Hello, my name is %s.  What is your %s?", "Mark", "name");
