QCollator支持英文按a-z、中文按拼音a-z排序，但多音字支持有bug，本貼著重處理多音字排序不準(zhǔn)的問(wèn)題。

#include <QCollator>
#include <QDebug>

void sortLocaleAwareStringList(QStringList& strList, QHash<QString,QString> &specialProcessingHash) {
    QLocale chineseLocale(QLocale::Chinese, QLocale::China);
    QCollator collator(chineseLocale);
    collator.setCaseSensitivity(Qt::CaseInsensitive);
    collator.setNumericMode(true);

    std::sort(strList.begin(), strList.end(), [&collator,specialProcessingHash](const QString& a, const QString& b) {

        if(!specialProcessingHash.empty()){
            QString str1 = specialProcessingHash.contains(a) ? specialProcessingHash[a] : a;
            QString str2 = specialProcessingHash.contains(b) ? specialProcessingHash[b] : b;
            return collator.compare(str1, str2) < 0;
        }else{
            return collator.compare(a, b) < 0;
        }
    });
}

測(cè)試

int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);

    QStringList strList{"任務(wù)","搞笑","長(zhǎng)度","012","022","112","gaoding","changdu","長(zhǎng)大"};
    QHash<QString,QString> specialProcessingHash;
    sortLocaleAwareStringList(strList,specialProcessingHash);
    qDebug()<<"1. sorted strlist  === "<< strList;


    // 定義目標(biāo)特殊字符串，以及其對(duì)應(yīng)的“cháng”發(fā)音拼音（用于強(qiáng)制排序）
    specialProcessingHash={{"長(zhǎng)度","常度"},{"長(zhǎng)寬比","常寬比"}};

    sortLocaleAwareStringList(strList,specialProcessingHash);
    qDebug()<<"2. sorted strlist  === "<< strList;

}

結(jié)果

1. sorted strlist  ===  ("012", "022", "112", "changdu", "gaoding", "搞笑", "任務(wù)", "長(zhǎng)大", "長(zhǎng)度")
2. sorted strlist  ===  ("012", "022", "112", "changdu", "gaoding", "長(zhǎng)度", "搞笑", "任務(wù)", "長(zhǎng)大")

從結(jié)果可以看出，第一次打印出來(lái)的內(nèi)容，”長(zhǎng)度“應(yīng)該被理解為”長(zhǎng)度”，但被解釋為“zhang度”，因?yàn)椤伴L(zhǎng)”是多音字；
經(jīng)過(guò)特別處理后，第二次打印出來(lái)的內(nèi)容，排序正常了；
