Sort apps according to usage in android

Question

I already has hashmap of apps usage. in details,a List of apps

//apps<Resolveinfo>
List<ResolveInfo> pkgAppsList = new ArrayList<ResolveInfo>();
PackageManager pm = this.getPackageManager();
pkgAppsList = pm.queryIntentActivities(mainIntent, 0);

and hashmap of popularity with package name as key string and usage as integer(number of user clicks on each app).

//hashmap<String,Integer>
public static HashMap listpopularity = new HashMap<String, Integer>();
listpopularity.put("com.example.app1",23)
listpopularity.put("com.example.app2",11)

what is best approach sort apps list according to package usages in hashmap. there may some apps that are not in hashmap usage because of user not clicked on app

@Manish Dubey: i know how track apps usage, i just want sort apps list , i saved user clicks on apps into hashmap as value and packagename as key, please read post carefully — hosein, Apr 16 '14 at 05:47
@SweetWisher ツ: i don't want sort hashmap, i want sort apps list according usage that saved on hashmap with packagename as key and usage as value , i want send this sorted list to listview adapter — hosein, Apr 16 '14 at 05:48
you need to sort the hashmap with values to get most number of user clicks for an app...then you can take the sorted list from the map using iterator... — Vamshi, Apr 16 '14 at 06:22
@Vamshi: you said me use just one hashmap instead of a list of apps and hashmap of ? — hosein, Apr 16 '14 at 06:33
If you have the value for each app clicks then one map is enough..let us assume you have 2 app...app1 with clicks 4 and app2 with clicks 5 , then you can put them in hashmap.put("app1", 4); hashmap.put("app2",5); so on....then you need to sort this map with values.... — Vamshi, Apr 16 '14 at 06:42
once you are done with it post your code...i will let you know how to sort hashmap with values... — Vamshi, Apr 16 '14 at 06:43
@Vamshi: no , sorry, i will post code in 2 hours,hashmap is like {"packagename1":4,"packagename1":2} and applist content list of app name , icon ,etc — hosein, Apr 16 '14 at 07:43
is there any relation between pkgAppsList and listpopularity? — Vamshi, Apr 16 '14 at 11:23
@Vamshi: yes ,appinfo=pkgAppsList.get(3), appinfo.packagename is equal "com.example.app1" — hosein, Apr 16 '14 at 14:58
@SweetWisher ツ: thanks for comparable keyword, i search and found what i want to do using comparable, i use comparable to sort apps not hashmap, update your comment as answer,please — hosein, Apr 19 '14 at 05:34

You need to use Comparable to sort the list....

a piece of code :

public class YourDataModel implements Comparable<YourDataModel> {
    @Override
        public int compareTo(YourDataModel o) {
            if (this.status.equals(o.status)) {
                return this.name.compareTo(o.name);
            } else {
                return this.status.compareTo(o.status);
            }
        }
}

Have a look here to get an idea to implement Comparable
