android – 按字母顺序排序列表

我在一个应用程序上工作,我用已安装的应用程序创建一个列表,让用户选择一个.除了一件事,我一切都在工作;按字母顺序排序.这是我正在使用的代码： @H_404_7@

@H_404_7@

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);

     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);
  }

  return apps;

}

Collections.sort(apps,new Comparator<App>() {

                @Override
                public int compare(App lhs,App rhs) {
                         //here gettitle() method return app name...
                    return lhs.gettitle().compareTo(rhs.gettitle());

                }
            });
