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];    }}
