将 API 中的字符串从括号开始分成两部分

Question

我有一个方法可以检查从 API 生成的引文是否在 130 个字符以内，然后将其分成两部分，前面部分是引文，第二部分是作者。

API 引用的 html 输出是：（例如）"Kindness in words creates confidence. (Lao Tzu)"

我想在两个单独的文本视图中显示它们并删除括号。 Textview 1 - 引用 Textview 2 - 作者（删除括号）

不幸的是，应用程序有时会崩溃并显示 IndexOutOfBoundsException，还有其他方法可以做到这一点吗？

先谢谢你。

private void check(String quote){

        //check length
        int length = quote.length();

        if (length <= 130) {

            //split to quote and author strings
            String[] parts = quote.split(Pattern.quote("(")); // Split on ( into 2 parts, quote and author
            String part1 = parts[0]; //quote
            String part2 = parts[1]; //author with )

            String removedSymbolsPart2 = part2.replaceAll("\)", ""); //remove ) symbol

            String finalQuote = Html.fromHtml(part1).toString();
            String finalAuthor = Html.fromHtml(removedSymbolsPart2).toString();

            quoteTextViewMain.setText(finalQuote);
            authorTextViewMain.setText(finalAuthor);

        } else {
            //get another quote
            getQuote();
        }
    }

Answer 1

 String tmp = "Kindness in words creates confidence. (Lao Tzu)";

 int index1 = tmp.indexOf("(");
 int index2 = tmp.indexOf(")");

 if(index1 > 0 && index2 > 0){
 String Author = tmp.substring(index1+1,index2);
 String quote  = tmp.substring(0,index1);
 System.out.println(Author);
 System.out.println(quote);
 }

输出

Lao Tzu
Kindness in words creates confidence.

Answer 2

我会用

String [] parts = quote.split ("(");  // no pattern neeeded
if (parts.length > 1) {
     String part1 = parts[0]; //quote
     String part2 = parts[1]; //author with )

     String removedSymbolsPart2 = part2.replace(")", "");  // not replaceAll
}
