Android替换字符串无效

Question

在以下字符串数组中，我有此标签：

String[] tags = {
        "<mft:A>",
        "<mft:S>",
        "<mft:R>",
        "</mft:A>",
        "</mft:S>",
        "</mft:R>"
};

我想用此html标签替换它们：

String[] replacementHtmlTags = {
        "<font color="red">",
        "<font color="green">",
        "<font color="blue">",
        "</font>",
        "</font>",
        "</font>"
};

现在定义目标和替换后，我的代码不起作用：

String rawParagraph = "11111 <mft:A>22222</mft:A> 33333 <mft:S> 44444 <mft:A> 555555 <mft:S> 66666 </mft:S></mft:A></mft:S><mft:R> 77777 </mft:R>"
for (int tag = 0; tag < tags.length; tag++) {
    rawParagraph.replace(tags[tag], replacementHtmlTags[tag]);
}

我认为您应该遵循此方法以获得更好的可用性和映射：

public static HashMap<String, String> keyVal;
static {
    keyVal = new HashMap<String, String>();
    keyVal.put("<mft:A>", "<font color=\red">");
    keyVal.put("<mft:S>", "<font color=\green">");
    keyVal.put("<mft:R>", "<font color=\blue">");
    keyVal.put("</mft:A>", "</font>");
    keyVal.put("</mft:S>", "</font>");
    keyVal.put("</mft:R>", "</font>");
}
public String replaceTag(String replace) {
    for(String key:keyVal.keySet())
        replace=replace.replaceAll(key,keyVal.get(key));
    return replace;
}
