このListViewを機能させようとしていますが、パッケージ名ではなくアプリケーション名でアルファベット順にリストを並べ替えようとしています。

MainActivity.java

// load list application
mListAppInfo = (ListView)findViewById(R.id.lvApps);
// create new adapter
AppInfoAdapter adapter = new AppInfoAdapter(this, Utilities.getInstalledApplication(this), getPackageManager());
// set adapter to list view        
mListAppInfo.setAdapter(adapter);

AppInfoAdapter.java

public AppInfoAdapter(Context c, List list, PackageManager pm) {
    mContext = c;
    mListAppInfo = list;
    mPackManager = pm;
}

public View getView(int position, View convertView, ViewGroup parent) {
    // get the selected entry
    ApplicationInfo entry = (ApplicationInfo) mListAppInfo.get(position);

    // reference to convertView
    View v = convertView;

    // inflate new layout if null
    if(v == null) {
        LayoutInflater inflater = LayoutInflater.from(mContext);
        v = inflater.inflate(R.layout.layout_appinfo, null);
    }

    // load controls from layout resources
    ImageView ivAppIcon = (ImageView)v.findViewById(R.id.ivIcon);
    TextView tvAppName = (TextView)v.findViewById(R.id.tvName);
    TextView tvPkgName = (TextView)v.findViewById(R.id.tvPack);

    // set data to display
    ivAppIcon.setImageDrawable(entry.loadIcon(mPackManager));
    tvAppName.setText(entry.loadLabel(mPackManager));
    tvPkgName.setText(entry.packageName);

    // return view
    return v;
}

Utilities.getInstalledApplication(this)使用するように変更しますCollections.sort()：

public static List<ApplicationInfo> getInstalledApplication(Context context) {
    PackageManager packageManager = context.getPackageManager();
    List<ApplicationInfo> apps = packageManager.getInstalledApplications(0);
    Collections.sort(apps, new ApplicationInfo.DisplayNameComparator(packageManager));
    return apps;
}

を使用している場合のbiegleuxコードのオプションpackageManager.queryIntentActivities(intent, 0)。

List<ResolveInfo> apps = packageManager.queryIntentActivities(intent, 0);
Collections.sort(apps, new ResolveInfo.DisplayNameComparator(packageManager));
