我有字符串:
Apple,Banana,Strawberry;柠檬,西瓜;橙
当我尝试这个时:
if(meaning.contains(";"))
{
meaning=meaning.replace(";", "\n");
}
结果:
Apple, Banana, Strawberry
Lemon, Watermelon
Orange
如何逐个替换部分字符串以替换“;”到“\ n”+ numStr?
1.Apple, Banana, Strawberry
2.Lemon, Watermelon
3.Orange

没有测试,但应该有效:
String[] lines = meaning.split(";");
StringBuilder res = new StringBuilder();
for (int i = 0, size = lines.length; i < size; i++) {
res.append(i + 1).append(". ").append(lines[i]).append("\n");
}
res.toString();

您可以使用以下代码。诀窍是使用String.split()
而不是String.replace()
。
if(meaning.contains(";"))
{
StringBuilder builder = new StringBuilder();
String[] meanings = meaning.split(";");
for (int i = 0; i < meanings.length; i++) {
builder.append(String.format(Locale.US, "%d. %s\n", i, meanings[i].trim()));
}
Log.d("meanings", builder.toString());
}
结果将打印出来:
1.苹果,香蕉,草莓
2.柠檬,西瓜
3.Orange
