public class TabActinity extends AppCompatActivity {


    private ViewPager viewpager;

    private TabLayout tablayout;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_tab_actinity);
        tablayout =  (TabLayout)findViewById(R.id.tablayout);
         viewpager =   (ViewPager)findViewById(R.id.viewpager);

         MyAdapter myAdapter = new MyAdapter(getSupportFragmentManager());
         viewpager.setAdapter(myAdapter);
         tablayout.setupWithViewPager(viewpager);

    }
    // 内部适配器
     class  MyAdapter extends FragmentPagerAdapter{

          String title[] = {"自定义1","自定义1"};
         public MyAdapter(FragmentManager fm) {
             super(fm);
             list.add(new Afragment());

         }

         @Override
         public int getCount() {

         }

         @Nullable
