android - using a FragmentTabHost with a ViewPager -

i want create swipe tab interface using fragmenttabhost viewpager. far got fragments slide. thing that's happening fragments able slide behind tabs disabled/stuck , not working. how can make fragmenttabhost tabs work viewpager swiping between tabs?

i tried using fragmenttabhost without viewpager, works fine, not working viewpager.

here's screenshot of looks like:

main java source code:

import java.util.list; import java.util.vector;  import android.os.bundle; 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.app.fragmenttabhost; import android.support.v4.view.viewpager;    public class mainactivity extends fragmentactivity {  private fragmenttabhost mtabhost;  private viewpager pager;  private mypageradapter adapter;  @override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_main);      mtabhost = (fragmenttabhost)findviewbyid(android.r.id.tabhost);          pager = (viewpager) findviewbyid(r.id.viewpager);                                            list<fragment> fragments = new vector<fragment>();         fragments.add(fragment.instantiate(this, batteryfragment.class.getname()));         fragments.add(fragment.instantiate(this, devicefragment.class.getname()));         fragments.add(fragment.instantiate(this, networkfragment.class.getname()));                  adapter = new mypageradapter(getsupportfragmentmanager(),       fragments);          pager.setadapter(adapter);          mtabhost.setup(this, getsupportfragmentmanager(), r.id.realtabcontent);          mtabhost.addtab(mtabhost.newtabspec("battery").setindicator("battery",                 getresources().getdrawable(r.drawable.ic_battery_tab)),                 batteryfragment.class, null);         mtabhost.addtab(mtabhost.newtabspec("network").setindicator("network",                 getresources().getdrawable(r.drawable.ic_network_tab)),                    networkfragment.class, null);         mtabhost.addtab(mtabhost.newtabspec("device").setindicator("device",                 getresources().getdrawable(r.drawable.ic_device_tab)),                 devicefragment.class, null);     }   public class mypageradapter extends fragmentpageradapter {     private list<fragment> fragments;      public mypageradapter(fragmentmanager fm, list<fragment> fragments) {         super(fm);         this.fragments = fragments;     }             @override     public fragment getitem(int arg0) {         // todo auto-generated method stub         return this.fragments.get(arg0);     }      @override     public int getcount() {         // todo auto-generated method stub         return this.fragments.size();     }  }   } 

xml code:

<linearlayout     android:orientation="vertical"     android:layout_width="match_parent"     android:layout_height="match_parent">      <tabwidget         android:id="@android:id/tabs"                     android:orientation="horizontal"         android:layout_width="match_parent"         android:layout_height="wrap_content"         android:layout_weight="0"/>             <framelayout         android:id="@android:id/tabcontent"         android:layout_width="0dp"         android:layout_height="0dp"         android:layout_weight="0"/>      <framelayout         android:id="@+id/realtabcontent"         android:layout_width="match_parent"         android:layout_height="0dp" />       <android.support.v4.view.viewpager         android:id="@+id/viewpager"         android:layout_width="fill_parent"         android:layout_height="0dp"         android:layout_weight="1"/>           </linearlayout>  </android.support.v4.app.fragmenttabhost> 

add following code:

              pager.setonpagechangelistener(new onpagechangelistener() {                  @override                 public void onpageselected(int arg0) {                     // todo auto-generated method stub                     mtabhost.setcurrenttab(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                  }             }); 

the problem when swiping fragments there no way tabs know it,by specifying through above code,you can make work. had same problem solved through this.hope helps.
