Android实现列表数据排序 Android实现列表数据按名称排序、中英文混合排序

Collections.sort(students, new SortChineseName());
  for (Student s : students) {
      Log.e("David", "名称正序排列：" + s.getName());
    }
    Log.d("David", "---------------------------------------");
    Collections.reverse(students);
    for (Student s : students) {
      Log.e("David", "名称倒序排列(一)：" + s.getName());
    }
    Log.d("David", "---------------------------------------");
    Collections.sort(students, Collections.reverseOrder(new SortChineseName()));
    for (Student s : students) {
      Log.e("David", "名称倒序排列(二)：" + s.getName());
}

class SortChineseName implements Comparator<ResolveInfo> {
    /**
     * create by Davide
     * 参数说明：
     * ResolveInfo 为你的List集合中的类-我这里为 android系统中apk信息类
     */

    private Context mContext;

    //构造-传进来context对象
    public SortChineseName(Context mContext) {
      this.mContext = mContext;
    }

    Collator cmp = Collator.getInstance(java.util.Locale.CHINA);

    @Override
    public int compare(ResolveInfo info1, ResolveInfo info2) {

      String apkName1 = info1.loadLabel(mContext.getPackageManager()).toString();
      String apkName2 = info2.loadLabel(mContext.getPackageManager()).toString();
      /**
       *create by Davide
       *开始比较-我这儿按照apk的名称排序，便获取apkName
       */
      if (cmp.compare(apkName1, apkName2) > 0) {
        return 1;
      } else if (cmp.compare(apkName1, apkName2) < 0) {
        return -1;
      }
      return 0;
    }
  }
