public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        init();
    }

    private void init() {
        TabLayout tab = (TabLayout) findViewById(R.id.tab);
        ViewPager vp = (ViewPager) findViewById(R.id.vp);

        //传入我们自定义的pageadapter
        vp.setAdapter(new Mypageradapter(getSupportFragmentManager()));

        //将viewpager和tablayout关联
        tab.setupWithViewPager(vp);

    }
}

<MyFragment>

public class MyFragment extends Fragment{

    private TextView tv_fragment;
    private String text;

    @Override
    public void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        Bundle arguments = getArguments();
        text = arguments.getString("text");

    }

    @Override
    public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);
    }

    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        View inflate = inflater.inflate(R.layout.myfragment,container,false);
        tv_fragment = (TextView) inflate.findViewById(R.id.tv_fragment);
         tv_fragment.setText(text);

        return inflate;
    }
}

<MyPageradapter>

public class Mypageradapter extends FragmentPagerAdapter {
    //创建数组 用来放标题
    private String[] titles = {"推荐", "热点", "北京", "视频", "军事娱乐", "热点", "北京", "视频", "军事娱乐"};
    //创建集合
    private List<Fragment> mFragments = new ArrayList<>();
    //这个为开启事物
    private FragmentManager mfragmentManager;

    public Mypageradapter(FragmentManager fm) {
        super(fm);
      mfragmentManager=fm;
    }

    @Override
    public Fragment getItem(int position) {
        //new对应的Fragment
        MyFragment myFragment = new MyFragment();
        Bundle bundle = new Bundle();
        bundle.putString("text",titles[position]);
        myFragment.setArguments(bundle);

        return myFragment;
    }

    @Override
    public int getCount() {
        return titles==null? 0 : titles.length;
    }
    //设置TableLayout中的每个tab的标题
    @Override
    public CharSequence getPageTitle(int position) {
        return titles[position];
    }
}
