跨字符串的getSpans返回跨度乱序? [英] getSpans for Spanned String returns spans out of order?

问题描述

我使用以下代码筛选出一个Spanned String，将所有粗体文本保存为数组中的字符串:

I use the following code to sift through a Spanned String saving all bold text as a string in an array:

StyleSpan[] spans = storyText.getSpans(0,
        storyText.length(), StyleSpan.class);
List<String> boldedWords = new ArrayList<String>();
for (StyleSpan span : spans) {
    if (span.getStyle() == Typeface.BOLD) {
        //start
        int s = storyText
                .getSpanStart(span);
        //end
        int e = storyText.getSpanEnd(span);
        boldedWords.add(storyText.subSequence(
                s, e).toString());
    }
}

String[] array = boldedWords
        .toArray(new String[boldedWords.size()]);

但是，我在数组中收到的字符串是乱序的.例如:

However, the Strings I receive back in the array are out of order. For example:

句子可能是(CAPS代表粗体文本):

Sentence might be (CAPS represent bold text):

storyText = "This ADJECTIVE NOUN is VERB"

我要返回的数组将是:名词，动词，形容词"的顺序.应该是:形容词，名词，动词" ​​

The array I'd get back would be: "Noun, Verb, Adjective" in that order. It should be: "Adjective, Noun, Verb"

对为什么会发生这种情况有任何见解吗?

Any insight on why this might be happening?

推荐答案

使用

Use int nextSpanTransition(int start, int limit, Class kind) to iterate over your spans. This way you get the reading order.
