android - Actionbar tabs are repeating during switching between fragments -


navigation drawer contains 4 items , each item contains 4 actionbar tabs ,while switching between menu items means if click on menu item 2 number of actionbar items changing 8 , if click on menu item3 number of actionbar tabs changing 12 ,how o stop repeation of tabs.here code

public class topicsfragment extends fragment {

public topicsfragment() { }  // declare tab variable     actionbar.tab alltopics, newcontent, staffpicks, popular, recommended;     fragment fragmenttab1 = new fragmenttab1();     fragment fragmenttab2 = new fragmenttab2();     fragment fragmenttab3 = new fragmenttab3();     fragment fragmenttab4 = new fragmenttab2();     fragment fragmenttab5 = new fragmenttab1();      @override     public view oncreateview(layoutinflater inflater, viewgroup tabs,             bundle savedinstancestate) {         view rootview = inflater.inflate(r.layout.fragment_topics, tabs, false);          actionbar actionbar = ((actionbaractivity) getactivity())                 .getsupportactionbar();           // create actionbar tabs         actionbar.setnavigationmode(actionbar.navigation_mode_tabs);          // set tab icon , titles         alltopics = actionbar.newtab().seticon(r.drawable.tab1);         newcontent = actionbar.newtab().seticon(r.drawable.tab1);         staffpicks = actionbar.newtab().seticon(r.drawable.tab1);         popular = actionbar.newtab().seticon(r.drawable.tab1);         recommended = actionbar.newtab().seticon(r.drawable.tab1);         // set tab listeners         alltopics.settablistener(new tablistener(fragmenttab1));         newcontent.settablistener(new tablistener(fragmenttab2));         staffpicks.settablistener(new tablistener(fragmenttab3));         popular.settablistener(new tablistener(fragmenttab2));         recommended.settablistener(new tablistener(fragmenttab2));          // add tabs actionbar         actionbar.addtab(alltopics);         actionbar.addtab(newcontent);         actionbar.addtab(staffpicks);         actionbar.addtab(popular);         actionbar.addtab(recommended);         return rootview;     }

}

that problem adding tabs when go in topicsfragment call oncreateview again , executing adding of tabs actionbar adding set of tabs current tabs.

solution:

you need check first if number of tabs 0 in actionbar.

sample:

actionbar.removealltabs(); if(actionbar.gettabcount() == 0)     {         actionbar.setnavigationmode(actionbar.navigation_mode_tabs);          // set tab icon , titles         alltopics = actionbar.newtab().seticon(r.drawable.tab1);         newcontent = actionbar.newtab().seticon(r.drawable.tab1);         staffpicks = actionbar.newtab().seticon(r.drawable.tab1);         popular = actionbar.newtab().seticon(r.drawable.tab1);         recommended = actionbar.newtab().seticon(r.drawable.tab1);         // set tab listeners         alltopics.settablistener(new tablistener(fragmenttab1));         newcontent.settablistener(new tablistener(fragmenttab2));         staffpicks.settablistener(new tablistener(fragmenttab3));         popular.settablistener(new tablistener(fragmenttab2));         recommended.settablistener(new tablistener(fragmenttab2));          // add tabs actionbar         actionbar.addtab(alltopics);         actionbar.addtab(newcontent);         actionbar.addtab(staffpicks);         actionbar.addtab(popular);         actionbar.addtab(recommended);     }
