问题 I have implemented a NavigationDrawer with a few items in it. Every item represents a different Fragment and one of them has tabs. My problem is that every time I open this Fragment the tabs reloaded! and added to the previous tabs. Why is this happening and how can I solve it? This is the Fragment with the tabs: public class fragment_profilo_tabs extends Fragment implements ActionBar.TabListener { private ViewPager viewPager; private TabsPagerAdapter mAdapter; private ActionBar actionBar; //
