tabLayout+viewpager实现tab controller

Gradle中添加support依赖

compile 'com.android.support:design:25.3.1'

布局文件添加viewpager和tablayout

private MyPageAdapter mMyPageAdapter;
    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        getSupportActionBar().setTitle("tabDemo");
        setContentView(R.layout.activity_main);
        initUI();
    }

    private void initUI(){
        TabLayout tabBottom = (TabLayout) findViewById(R.id.tabBottom);

        ViewPager viewPager = (ViewPager) findViewById(R.id.viewPager);
        viewPager.setOffscreenPageLimit(2);
        FragmentManager manager = getSupportFragmentManager();
        viewPager.setAdapter(new MyPageAdapter(manager));
        viewPager.setCurrentItem(0);

        tabBottom.setupWithViewPager(viewPager);

        int tabCount =tabBottom.getTabCount();
        for(int i=0;i

调用setupWithViewPager把tablayout和viewpager关联起来。

public class Fragment1 extends Fragment {
    private static final String TAG = "Fragment1";
    public static Fragment1 newInstance(){
        Fragment1 fragment1 = new Fragment1();
        return fragment1;
    }
    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        super.onCreateView(inflater, container, savedInstanceState);
        View view = inflater.inflate(R.layout.fragment_1, null);
        return view;
    }

}

一个简单的tab控制器完成了。
