java - 如何在android中替换字符串中的单词

Question

我有一个字符串，值为 hi，how r u{name};而且我还有一个大小为 3 的数组我想从字符串中找到单词“{name}”并将其替换为当前数组值 a[i]。我已经尝试过这段代码

Resources res = getResources ();
String []Questions=res. getStringArray (R.array.faq_ques);

int Questions_Array_length = Questions .length;

for(i=0; i<Questions_Array_length; i++) {
  String Amith= "hi how r u {Name}";
  Amith.replace("{Name}", Questions[i]);
}

Answer 1

Amith = Amith.replace("{Name}", Questions[i]);
