Question

例如只显示汽车; “梅赛德斯”或 “日产？”
或者通过YearOfManufacture;只有汽车 2004年在我的listView中制造？

My Automobil类看起来像这样

public class AutoMobil {
     private String make;
     private String brandName;
     private int yearOfManufacture;
  }

我的autoMobil填充列表如下所示;

private void autoMobileList() {
    MyAutoMobilList.add(new AutoMobil(“Toyota’’, ‘’Corolla’’, ‘’2011’’));
    MyAutoMobilList.add(new AutoMobil(“Toyota’’, ‘’Corolla’’, ‘’2002’’));
    MyAutoMobilList.add(new AutoMobil(“Toyota’’, ‘’Mark2’’, ‘’1998’’));
    MyAutoMobilList.add(new AutoMobil(“Toyota’’, ‘’Camry’’, ‘’2004’’));
    MyAutoMobilList.add(new AutoMobil(“Toyota’’, ‘’Corona’’, ‘’2011’’));
    MyAutoMobilList.add(new AutoMobil(“Nissan’’, ‘’March’’, ‘’2013’’));
    MyAutoMobilList.add(new AutoMobil(“Nissan’’, ‘’Micra’’, ‘’2001’’));
    MyAutoMobilList.add(new AutoMobil(“Nissan’’, ‘’Laurel’’, ‘’2014’’));
    MyAutoMobilList.add(new AutoMobil(“Mercedes’’, ‘’SL500’’, ‘’2004’’));
    MyAutoMobilList.add(new AutoMobil(“Mercedes’’, ‘’190E’’, ‘’1992’’));
    MyAutoMobilList.add(new AutoMobil(“Mercedes’’, ‘’C200’’, ‘’1993’’));
    MyAutoMobilList.add(new AutoMobil(“Toyota’’, ‘’Hiace’’, ‘’1998’’));
    MyAutoMobilList.add(new AutoMobil(“Toyota’’, ‘’Hiace’’, ‘’2003’’));
    MyAutoMobilList.add(new AutoMobil(“Toyota’’, ‘’Vitz’’, ‘’2004’’));

}

Answer 2

按品牌名称排序（String）：

Collections.sort(list, new Comparator<AutoMobil>() {
        public int compare(AutoMobil v1, AutoMobil v2) {
        return v1.getBrandName().compareTo(v2.getBrandName());
    }
});

按制造年份排序（int）：

Collections.sort(conversations, new Comparator<AutoMobil>(){
                public int compare(AutoMobil s1, AutoMobil s2) {
        if (s1.getYearOfManufacture() < s2.getYearOfManufacture())
            return 1;
        if (s1.getYearOfManufacture() > s2.getYearOfManufacture())
            return -1;
        else
            return 0;
    }
});

仅显示特定项目：

ArrayList<AutoMobil> list_to_show = new ArrayList<AutoMobil>();
for (int i = 0; i < list.size(); i++)
     if (list.getBrandName().equals("Nissan"))
        list_to_show.add(list.get(i));

ListView：如何按特定元素对列表或arrayList进行排序？
