您好我跟着下面的教程，并成功上市我所有的应用程序安装在我的应用程序。

列表样式的所有安装的应用程序

不过它不会列出按字母顺序，我可以不知道如何对它们进行排序，使他们。任何帮助，这将大大AP preciated。我试着像这样的一些事情

 类IgnoreCaseComparator实现比较＆LT;字符串＆GT; {
            公众诠释比较（STRA字符串，字符串STRB）{
                返回strA.compareToIgnoreCase（STRB）;
            }
        }
        IgnoreCaseComparator ICC =新IgnoreCaseComparator（）;
        java.util.Collections.sort（SomeArrayList，ICC）;
 

但无法弄清楚如何将其应用到应用程序列表的标题。谢谢你的帮助，这

感谢您的回复我做了以下，但有一个错误的排序。错误读取在类型类别的方法的排序（列表，比较器）是不适用的参数（列表，ApplicationInfo.DisplayNameComparator）

 私人列表＆LT;应用＆GT; loadInstalledApps（布尔includeSysApps）{
      名单＆LT;应用＆GT;应用程序=新的ArrayList＆LT;应用＆GT;（）;

      PackageManager packageManager = getPackageManager（）;

      名单＆LT; PackageInfo＆GT;包= packageManager.getInstalledPackages（0）;

      的for（int i = 0; I＆LT; packs.size（）;我++）{
         PackageInfo p值= packs.get（ⅰ）;
         ApplicationInfo A = p.applicationInfo;
         如果（（includeSysApps）及！及（（a.flags＆安培; ApplicationInfo.FLAG_SYSTEM）== 1））{
            继续;
         }
         应用程序=新的应用程序（）;
         app.setTitle（p.applicationInfo.loadLabel（packageManager）的ToString（））;
         app.setPackageName（p.packageName）;
         app.setVersionName（p.versionName）;
         app.setVersion code（p.version code）;
         CharSequence的描述= p.applicationInfo.loadDescription（packageManager）;
         app.setDescription（说明​​= NULL description.toString（）：！？）;
         apps.add（应用程序）;
      }
      Collections.sort（应用程序，新的ApplicationInfo.DisplayNameComparator（packageManager））;
      返回应用程序;
   }
 

解决方案

当您查询的Andr​​oid让安装的应用程序的列表，你会得到一个名单，其中，ApplicationInfo＆GT; 。安卓提供一个 ApplicationInfo.DisplayNameComparator 对于那些：

  Col​​lections.sort（应用程序，新的ApplicationInfo.DisplayNameComparator（PM））;
 

（其中时是一个实例 PackageManager ）。

Hi I followed the below tutorial and successfully listed all of my installed apps in my application.

List all installed apps in style

However it does not list them alphabetically and i can not figure out how to sort them so that they are. Any help with this would be greatly appreciated. I've tried a few things like this

class IgnoreCaseComparator implements Comparator<String> {
            public int compare(String strA, String strB) {
                return strA.compareToIgnoreCase(strB);
            }
        }
        IgnoreCaseComparator icc = new IgnoreCaseComparator();
        java.util.Collections.sort(SomeArrayList,icc);

But can't figure out how to apply it to the app list titles. Thank you for any help with this

===EDIT===

Thank you for the reply I did the following but have an error on sort. The error reads "The method sort(List, Comparator) in the type Collections is not applicable for the arguments (List, ApplicationInfo.DisplayNameComparator)"

   private List<App> loadInstalledApps(boolean includeSysApps) {
      List<App> apps = new ArrayList<App>();

      PackageManager packageManager = getPackageManager();

      List<PackageInfo> packs = packageManager.getInstalledPackages(0); 

      for(int i=0; i < packs.size(); i++) {
         PackageInfo p = packs.get(i);
         ApplicationInfo a = p.applicationInfo;
         if ((!includeSysApps) && ((a.flags & ApplicationInfo.FLAG_SYSTEM) == 1)) {
            continue;
         }
         App app = new App();
         app.setTitle(p.applicationInfo.loadLabel(packageManager).toString());
         app.setPackageName(p.packageName);
         app.setVersionName(p.versionName);
         app.setVersionCode(p.versionCode);
         CharSequence description = p.applicationInfo.loadDescription(packageManager);
         app.setDescription(description != null ? description.toString() : "");
         apps.add(app);
      }
      Collections.sort(apps, new ApplicationInfo.DisplayNameComparator(packageManager));
      return apps;
   }

When you query Android to get the list of installed applications, you will get a List<ApplicationInfo>. Android supplies an ApplicationInfo.DisplayNameComparator for those:

Collections.sort(apps, new ApplicationInfo.DisplayNameComparator(pm)); 

(where pm is an instance of PackageManager).
