try this -

provide the package_name of application you want to show and compare it with package name present in device

//for browser application given package name as com.android.browser

            for (int i = 0; i < packs.size(); i++) {
       if ((p.packageName).equals("com.android.browser")) {
            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);
  }
}

hope this will help you.

same way you can give 'if statement' for other 4 application — Shree, Jun 13 '13 at 12:50

You need a screening process to see if the application is in the list of your mentioned applications store your entered app package name in array and see if the current app is in that list if it is there add it to the list and then display listView using this list

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

  // the package manager contains the information about all installed apps
  PackageManager packageManager = getPackageManager();

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

  for(int i=0; i < packs.size(); i++) {
     PackageInfo p = packs.get(i);
     ApplicationInfo a = p.applicationInfo;
     // skip system apps if they shall not be included
     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() : "");

if( Arrays.asList(appliation1.packageName,appliation2.packageName,appliation3.packageName).contains(p.packageName) )  
     apps.add(app);
  }
  return apps;
  }

this is my code which show all install application
