Lock page fragment in ViewPager android -

how can lock paging in fragment activity of viewpager fragment swipe.i'm performing operations using progressbar in 1 fragment.while progressing progressbar fragment gets changes because of swipe action.so while progessing progressbar want stop swiping.how this?is there solution??

activity.xml file-

<android.support.v4.view.viewpager xmlns:android="http://schemas.android.com/apk/res/android"     xmlns:tools="http://schemas.android.com/tools"     android:id="@+id/pager"     android:layout_width="match_parent"     android:layout_height="match_parent"        tools:context=".mainfragmentactivity" >      <android.support.v4.view.pagertitlestrip         android:id="@+id/pager_title_strip"         android:layout_width="match_parent"         android:layout_height="wrap_content"         android:layout_gravity="top"         android:background="@drawable/title"         android:paddingbottom="4dp"         android:paddingtop="4dp"         android:textcolor="#fff" />  </android.support.v4.view.viewpager> 

fragment activity-

public class mainfragmentactivity extends fragmentactivity {      private sectionspageradapter msectionspageradapter;     private viewpager mviewpager;     private context mcontext;     private pagertitlestrip pt;       @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         requestwindowfeature(window.feature_no_title);         setcontentview(r.layout.activity);          msectionspageradapter = new sectionspageradapter(getsupportfragmentmanager(),mcontext);         mcontext=this;         mviewpager = (viewpager) findviewbyid(r.id.pager);         mviewpager.setadapter(msectionspageradapter);         pt=(pagertitlestrip) findviewbyid(r.id.pager_title_strip);       } 

sectionspageradapter-

public class sectionspageradapter extends fragmentpageradapter {      context mcontext;     fragment fragment;      public sectionspageradapter(fragmentmanager fm, context context) {         super(fm);         mcontext=context;     }      @override     public fragment getitem(int position) {         // getitem called instantiate fragment given page.         // return dummysectionfragment (defined static inner class         // below) page number lone argument.         if(position==0){             fragment = new selectitem();             bundle args = new bundle();             args.putint(arg_section_number, position + 1);             fragment.setarguments(args);         }         if(position==1){             fragment = new culation();             bundle args = new bundle();             args.putint(arg_section_number, position + 1);             fragment.setarguments(args);         }         if(position==2){                         fragment = new graphdisplay();             bundle args = new bundle();             args.putint(arg_section_number, position + 1);             fragment.setarguments(args);         }         return fragment;     }      @override     public int getcount() {         return 3;     }      @override     public charsequence getpagetitle(int position) {         switch (position) {         case 0 :             return "select item";         case 1:             return "calculation";         case 2:             return "graph";         }         return null;     } } 

try setting clickable false:

mviewpager.setclickable(false); 

if works can create function in activity disable swipe event on view pager , call function in fragment in event of progress bar show , function enable it.

subclass viewpager , override ontouch event example:

edit

public class nonswipeableviewpager extends viewpager {     private boolean lock;     public void lock(){         lock=true;     }         public void unlock(){         lock=false;     }     public nonswipeableviewpager(context context) {         super(context);     }      public nonswipeableviewpager(context context, attributeset attrs) {         super(context, attrs);     }      @override     public boolean ontouchevent(motionevent event) {         if(lock)         return false;else{         return super.ontouchevent(event);         }     } }
