@override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.find_stores_0_tabview__landing);          // actionbar button         getsupportactionbar().setdisplayhomeasupenabled(true);           // initilization          // creating toolbar , setting toolbar activity          toolbar = (toolbar) findviewbyid(r.id.tool_bar);         setsupportactionbar(toolbar);          // creating viewpageradapter , passing fragment manager, titles         // fot tabs , number of tabs.         adapter = new viewpageradapter(getsupportfragmentmanager(), titles,numboftabs);          // assigning viewpager view , setting adapter         pager = (viewpager) findviewbyid(r.id.pager);         pager.setadapter(adapter);          // assiging sliding tab layout view         tabs = (slidingtablayout) findviewbyid(r.id.tabs);         tabs.setdistributeevenly(true); // make tabs fixed set true,                                         // makes tabs space evenly in                                         // available width          // setting custom color scroll bar indicator of tab view         tabs.setcustomtabcolorizer(new slidingtablayout.tabcolorizer() {             @override             public int getindicatorcolor(int position) {                 return getresources().getcolor(r.color.tabsscrollcolor);             }         });          // setting viewpager slidingtabslayout         tabs.setviewpager(pager);            // end of oncreate      } 

i suggest define different theme them.

and think problem wasn't caused sliding tab , check code again.

your first activity theme :

<style name="apptheme" parent="theme.appcompat.light.noactionbar">     <item name="colorprimary">@color/colorprimary</item>     <item name="colorprimarydark">@color/colorprimarydark</item> </style> 

your second activity theme:

<style name="apptheme2" parent="theme.appcompat.light">     <item name="colorprimary">@color/colorprimary</item>     <item name="colorprimarydark">@color/colorprimarydark</item> </style> 

in androidmanifest.xml

<activity android:name=".first activity" android:theme="@style/apptheme"/> <activity android:name=".second activity" android:theme="@style/apptheme2"/>
