android - How to create dynamically Fragment pager adapter -

i unable create dynamic layout each tabs, able create tabs dynamically constructor(public mypageradapter(fragmentmanager fm , int nooftabs)), coudn't inflate view each tabs creating each fragment should dyanmic.

public class mypageradapter extends fragmentpageradapter  {          private final string[] titles = { "categories", "home", "top paid", "top free", "top grossing", "top new paid",                 "top new free", "trending" };          int nooftabs;          **public mypageradapter(fragmentmanager fm , int nooftabs)          {                        super(fm);             this.nooftabs = nooftabs;         }**          /*public mypageradapter(fragmentmanager fm)          {             super(fm);         }*/          @override         public charsequence getpagetitle(int position) {             return titles[position];         }          @override         public int getcount() {             return nooftabs; //titles.length;         }          @override         public fragment getitem(int position) {             return superawesomecardfragment.newinstance(position);         }      } 

i facing problem here should dynamic , not static 3 fragments(fragmenta, fragmentb , fragmentc), can number of fragments depending on int nooftabs:

@override public fragment getitem(int position) {     fragment fragment =null;     switch (position) {         case 0:             fragment = new fragmenta();             break;         case 1:             fragment = new fragmentb();             break;                       case 2:             fragment = new fragmentc();             break;          }     return fragment;     } 

thanks in advance if 1 me in this, using of library pagerslidingtabstrip.

you can storing list of fragments , titles in pageradapter:

/**  * tabspageradapter.  *  * @author niels  * @version 1.0  * @since 11-9-2015  */ public class tabspageradapter extends fragmentpageradapter {      /**      * contains fragments.      */     private list<fragment> fragments = new arraylist<>();      /**      * contains tab titles.      */     private list<string> tabtitles = new arraylist<>();      /**      * creates new pageradapter instance.      *      * @param fragmentmanager fragmentmanager.      */     public tabspageradapter(fragmentmanager fragmentmanager) {         super(fragmentmanager);     }      @override     public int getcount() {         return fragments.size();     }      @override     public fragment getitem(int position) {         return fragments.get(position);     }      @override     public charsequence getpagetitle(int position) {         return tabtitles.get(position);     }      /**      * adds fragment list, adds fragment's tab title.      *      * @param fragment new instance of fragment associated tab.      * @param tabtitle string containing tab title fragment.      */     public void addfragment(fragment fragment, string tabtitle) {         fragments.add(fragment);         tabtitles.add(tabtitle);     }  } 

you can use such:

@override public void oncreate() {     adapter = new tabspageradapter(getsupportfragmentmanager()); //tabspageradapter = whatever named pageradapter     addfragments();     viewpager.setadapter(adapter); //viewpager = viewpager view instance     strip.setviewpager(viewpager); //strip = pagerslidingtabstrip view instance }  /**  * adds fragments adapter.  */ private void addfragments() {     adapter.addfragment(new fragment1(), "fragment1");     adapter.addfragment(new fragment2(), "fragment2");     adapter.addfragment(new fragment3(), "fragment3");     adapter.addfragment(new fragment4(), "fragment4"); }
