在Android的Textview中，如何在段落的单词之间添加空格来删除末尾的空格？

TextView textView = findViewById(R.id.textView);
String text = textView.getText().toString();

// 使用正则表达式匹配文本内容中的单词
String regex = "\\b(\\w+)\\b";
Pattern pattern = Pattern.compile(regex);
Matcher matcher = pattern.matcher(text);

StringBuilder result = new StringBuilder();
int lastEnd = 0;

// 在匹配到的单词之间添加空格
while (matcher.find()) {
    int start = matcher.start();
    int end = matcher.end();

    result.append(text.substring(lastEnd, start));
    result.append(matcher.group(1));
    result.append(" ");

    lastEnd = end;
}

result.append(text.substring(lastEnd));

// 更新TextView的文本内容
textView.setText(result.toString());
