Question

下面的代码返回4个值（91891,31888,7820,181655），我想将它们存储在4个单独的长值中，以便我以后可以比较它们。

这可能吗？谢谢你的帮助。

private long getLatest(final ForumPage page) {
    long latest = -1;
    long val1; //91891
    long val2; //31881
    long val3; //7820
    long val4; //181655

    for (final Topic t : page.getTopics()) {
        Date d;
        try {
            d = Util.parseDate(t.getTime());
        } catch (final ParseException e) {
            d = null;
        }

        if (d != null) {
            final long time = d.getTime();
            if (time > latest)
                latest = time;
        }
    }
    Log.v("COUNT: ", String.valueOf(page.getTopicCount()));
    return latest;
}

01-01 11:55:53.928: E/COUNT:(2871): 91891
01-01 11:55:54.548: E/COUNT:(2871): 31881
01-01 11:55:54.796: E/COUNT:(2871): 7820
01-01 11:55:56.378: E/COUNT:(2871): 181655

使用getTopicCount编辑，ForumPage类：

public class ForumPage implements Serializable {

private static final long serialVersionUID = 1057995133618054945L;

private int page;
private int maxPage;
private int nextPageStart;
private int topicCount;
private String name;
private final List<Topic> topics = new ArrayList<Topic>();

public int getPage() {
    return page;
}

public void setPage(final int page) {
    this.page = page;
}

public int getMaxPage() {
    return maxPage;
}

public void setMaxPage(final int maxPage) {
    this.maxPage = maxPage;
}

public int getNextPageStart() {
    return nextPageStart;
}

public void setNextPageStart(final int nextPageStart) {
    this.nextPageStart = nextPageStart;
}

public int getTopicCount() {
    return topicCount;
}

public void setTopicCount(final int topicCount) {
    this.topicCount = topicCount;
}

public String getName() {
    return name;
}

public void setName(final String name) {
    this.name = name;
}

public void addTopic(final Topic topic) {
    topics.add(topic);
}

public Topic[] getTopics() {
    return topics.toArray(new Topic[topics.size()]);
}

}

在您的班级中创建一个Integer（或ArrayList，如您所愿）的列表：

List<Integer> valuesList = new List<Integer>();

然后保存您的值：

private long getLatest(final ForumPage page) {
    long latest = -1;    
    for (final Topic t : page.getTopics()) {
        Date d;
        try {
            d = Util.parseDate(t.getTime());
        } catch (final ParseException e) {
            d = null;
        }

        if (d != null) {
            final long time = d.getTime();
            if (time > latest)
                latest = time;
        }
    }
    Log.v("COUNT: ", String.valueOf(page.getTopicCount()));
    valuesList.add(page.getTopicCount());

    return latest;
}

您可以在valuesList

中找到所有值

这里编辑的是getTopics和getLatest函数：

public Topic[] getTopics() { //4 Topics
    return topics.toArray(new Topic[topics.size()]);
}

public long getLatest(final String suffix) {
    final String latest = get(KEY_LATEST + suffix);
    if (latest != null) {
        try {
            return Long.parseLong(latest);
        } catch (final NumberFormatException e) {
            //
        }
    }
    return -1;
}

单独保存长值
