android - Change multiple fragments from ONE ActionTab -

i have tried multiple times add two fragments 1 action tab.when press action tab "search" want load 1 fragment when swipe go 2nd fragment under action tab.please find below code used.

mainactivity.java

package com.example.swipetabs; import com.tabs.*; import android.os.bundle; import android.app.actionbar; import android.app.actionbar.tab; import android.app.actionbar.tablistener; import android.app.activity; import android.app.fragmenttransaction; import android.support.v4.app.fragment; import android.support.v4.app.fragmentactivity; import android.support.v4.app.fragmentmanager; import android.support.v4.app.fragmentpageradapter; import android.support.v4.view.viewpager; import android.view.menu; import android.widget.imageview; import com.comparenow.*;  public class mainactivity extends fragmentactivity implements tablistener {      actionbar action_bar;     viewpager viewpager;     imageview creditcards;     fragment fragement;     fragment fragement1;     fragment fragement2;       @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.activity_main);          viewpager=(viewpager)findviewbyid(r.id.pager);           viewpager.setadapter(new myadoptor(getsupportfragmentmanager()));         viewpager.setonpagechangelistener(new viewpager.onpagechangelistener() {              @override             public void onpageselected(int arg0) {                 // todo auto-generated method stub                 action_bar.setselectednavigationitem(arg0);              }              @override             public void onpagescrolled(int arg0, float arg1, int arg2) {                 // todo auto-generated method stub              }              @override             public void onpagescrollstatechanged(int arg0) {                 // todo auto-generated method stub              }         });          action_bar=getactionbar();         //action_bar.setbackgrounddrawable(d)         action_bar.setnavigationmode(actionbar.navigation_mode_tabs);          actionbar.tab tab1=action_bar.newtab();         tab1.settext("login");          tab1.settablistener(this);          actionbar.tab tab2=action_bar.newtab();         tab2.settext("compare now");         tab2.settablistener(this);          actionbar.tab tab3=action_bar.newtab();         tab3.settext("search");         tab3.settablistener(this);          action_bar.addtab(tab1);         action_bar.addtab(tab2);         action_bar.addtab(tab3);      }      public void switchtofragmentb(){         viewpager.setcurrentitem(4);      }      @override     public void ontabreselected(tab arg0, fragmenttransaction arg1) {         // todo auto-generated method stub       }      @override     public void ontabselected(tab tab, fragmenttransaction ft) {         // todo auto-generated method stub         //this code         viewpager.setcurrentitem(tab.getposition());          string name=(string)tab.gettext().tostring();           // compare tab                  if (name == "search") {             //load 1st fragment             fragement1= new creditcards();             getfragmentmanager().begintransaction()                     .setcustomanimations(android.r.animator.fade_in,                             android.r.animator.fade_out)                     .replace(r.id.store_fragment_container, fragment).commit();              //load 2nd fragment             fragement2 = new loginfrag();             getfragmentmanager().begintransaction()                     .setcustomanimations(android.r.animator.fade_in,                             android.r.animator.fade_out)                     .replace(r.id.imageview1,fragement2).commit();      }      @override     public void ontabunselected(tab tab, fragmenttransaction ft) {         // todo auto-generated method stub      }   }   class myadoptor extends fragmentpageradapter {      public myadoptor(fragmentmanager fm) {         super(fm);                 // todo auto-generated constructor stub     }      @override     public fragment getitem(int arg0) {         // todo auto-generated method stub          fragment fragement=null;         if(arg0==0)         {             fragement=new loginfrag();         }         if(arg0==1)         {             fragement=new comparefrag();         }         if(arg0==2)         {             fragement=new searchfrag();         }            system.out.print("<><><><>");         return fragement;      }      @override     public int getcount() {         // todo auto-generated method stub         return 3;     }  } 

creditcards.java (fragment) /loginfrag .java (fragement ) both same its's got corresponsing xml files well.

package com.comparenow;  import com.example.swipetabs.r; import com.example.swipetabs.r.layout; import android.os.bundle; import android.support.v4.app.fragment; import android.view.layoutinflater; import android.view.view; import android.view.viewgroup;  public class creditcards extends fragment {      public creditcards() {         // required empty public constructor     }      @override     public view oncreateview(layoutinflater inflater, viewgroup container,             bundle savedinstancestate) {         // inflate layout fragment         return inflater.inflate(r.layout.creditcards_c, container, false);     } 

i have problem below code segment,im not sure parameters.

fragement1= new creditcards();             getfragmentmanager().begintransaction()                     .setcustomanimations(android.r.animator.fade_in,                             android.r.animator.fade_out)                     .replace(r.id.store_fragment_container, fragment).commit();              //load 2nd fragment             fragement2 = new loginfrag();             getfragmentmanager().begintransaction()                     .setcustomanimations(android.r.animator.fade_in,                             android.r.animator.fade_out)                     .replace(r.id.imageview1,fragement2).commit();      } 

in general, believe you're looking create viewpager within fragment within viewpager.

your mainactivity more or less right, should forget below viewpager.setcurrentitem(tab.getposition()) in ontabselected(). instead of using searchfrag in pager adapter's getitem() method, you're going need create , use parent fragment both searchfrag , whatever other fragment want scroll in search tab. fragment can simple , contain viewpager , pager adapter. in parent fragment's pager adapter, you'll write getitem() method return searchfrag item 0 , whatever other fragment want scroll item 1. both of these fragment's under search tab.

for example, fragmentpageradapter hold searchfrag , other fragment should have getitem() method following:

public static class samplefragmentadapter extends fragmentpageradapter {      public samplefragmentadapter(fragmentmanager fm) {         super(fm);     }      @override     public fragment getitem(int arg0) {         if(arg0 == 0){             return new searchfrag();         } else {             return new otherfragmentundersearchtab();         }      }      @override     public int getcount() {         return 2;     }  } 

this parent fragment (let's call parentfragment) should replace searchfrag in getitem() method of myadoptor so:

@override public fragment getitem(int arg0) {     // todo auto-generated method stub      fragment fragement=null;     if(arg0==0)     {         fragement=new loginfrag();     }     if(arg0==1)     {         fragement=new comparefrag();     }     if(arg0==2)     {         fragement=new parentfragment();     }        system.out.print("<><><><>");     return fragement;  }
