Answer 1

試試這個

TabLayout tabLayout = (TabLayout) findViewById(R.id.tabs); 
tabLayout.getSelectedTabPosition(); 

Answer 2

tabLayout.setOnTabSelectedListener(
        new TabLayout.ViewPagerOnTabSelectedListener(viewPager) { 
         @Override 
         public void onTabSelected(TabLayout.Tab tab) { 
          super.onTabSelected(tab); 
          currentPage = tab.getPosition(); 

         } 
        }); 
     } 

Answer 3

在你的活動實施OnTabChangeListener， 然後設置偵聽器TabHost tabHost.setOnTabChangedListener(this);

@Override 
    public void onTabChanged(String id) { 
     Log.i("INDEX->", "Selected TAB Index - "+ tabHost.getCurrentTab()); 
}

          super.onTabSelected(tab); 
          position = tab.getPosition(); 

         } 
        });
