我正在Android Studio中开发Android社交应用
任何人都可以知道如何在发布新状态时过滤坏词/冒犯性词语。
例如，我发布了一些不好的词语和令人反感的内容，它会变成这样的＆＃34; ****＆＃34; 当我发布很多单词时它会变成这样的＆＃34;我现在就打你的*****＆＃34;
如果你知道我真的需要它，请 先谢谢你。
这是我的 PublishingActivity.java 代码

假设您有一个输入字符串dataview v=dt.defaultview; // ( dt datatable)
v.sort="columnName ASC"; // ASC / DESC for ascending / descending order
dt=v.toTable();
以及要用星号替换的单词列表：
s您只需迭代令人反感的单词列表，查看输入字符串是否包含一个，并执行替换。最简单的方法是使用正则表达式：
String s = "i will hit your head right now";
List<String> words = Arrays.asList("head", "now"); // suppose these words are offensive
我在正则表达式模式的前端和末尾添加for (String word : words) {
Pattern rx = Pattern.compile("\\b" + word + "\\b", Pattern.CASE_INSENSITIVE);
s = rx.matcher(s).replaceAll(new String(new char[word.length()]).replace('\0', '*'));
}
// s: i will hit your **** right ***
以匹配整个单词（即“head”将被处理，“header”将不会）。而这篇文章：
\\b构建一个新的new String(new char[n]).replace('\0', c)
字符n字符串。
之后，在您需要的地方使用生成的c。

这是一个关于java的基本知识，而不是与android相关的。这样做的一种方法是列出坏词并将其替换为用户输入的字符串。请参阅下面的示例
String userInput = "this is an example of some bad words";
ArrayList<String> badWords = new ArrayList<>();
badWords.add("some");
badWords.add("bad");
badWords.add("words");
for (int i = 0; i < badWords.size(); i++) {
String badWord = badWords.get(i);
if(userInput.toLowerCase().contains(badWord)){
userInput = userInput.replace(badWord, "*****");
}
}
