ViewPager实现页卡的最新方法--简洁的TabLayout（谷歌支持包）

效果图：

添加依赖包：

compile 'com.android.support:design:22.2.0'

布局文件：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical">

    <android.support.design.widget.TabLayout  android:id="@+id/tabs" android:layout_width="match_parent" android:layout_height="wrap_content" app:tabIndicatorColor="@color/red" app:tabSelectedTextColor="@color/red" app:tabTextColor="@color/black"/>

    <!--可滑动的布局内容-->
    <android.support.v4.view.ViewPager  android:id="@+id/vp_view" android:layout_width="match_parent" android:layout_height="wrap_content"/>
</LinearLayout>

页面代码：

public class FiveActivity extends Activity {
    private TabLayout mTabLayout;
    private ViewPager mViewPager;

    private LayoutInflater mInflater;
    private List<String> mTitleList = new ArrayList<>();//页卡标题集合
    private View view1, view2, view3, view4, view5;//页卡视图
    private List<View> mViewList = new ArrayList<>();//页卡视图集合

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

        mViewPager = (ViewPager) findViewById(R.id.vp_view);
        mTabLayout = (TabLayout) findViewById(R.id.tabs);

        mInflater = LayoutInflater.from(this);
        view1 = mInflater.inflate(R.layout.activity_main, null);
        view2 = mInflater.inflate(R.layout.activity_main, null);
        view3 = mInflater.inflate(R.layout.activity_main, null);
        view4 = mInflater.inflate(R.layout.activity_main, null);
        view5 = mInflater.inflate(R.layout.activity_main, null);

        //添加页卡视图
        mViewList.add(view1);
        mViewList.add(view2);
        mViewList.add(view3);
        mViewList.add(view4);
        mViewList.add(view5);

        //添加页卡标题
        mTitleList.add("No:1");
        mTitleList.add("No:2");
        mTitleList.add("No:3");
        mTitleList.add("No:4");
        mTitleList.add("No:5");


        mTabLayout.setTabMode(TabLayout.MODE_FIXED);//设置tab模式，当前为系统默认模式
        mTabLayout.addTab(mTabLayout.newTab().setText(mTitleList.get(0)));//添加tab选项卡
        mTabLayout.addTab(mTabLayout.newTab().setText(mTitleList.get(1)));
        mTabLayout.addTab(mTabLayout.newTab().setText(mTitleList.get(2)));
        mTabLayout.addTab(mTabLayout.newTab().setText(mTitleList.get(3)));
        mTabLayout.addTab(mTabLayout.newTab().setText(mTitleList.get(4)));


        MyPagerAdapter mAdapter = new MyPagerAdapter(mViewList);
        mViewPager.setAdapter(mAdapter);//给ViewPager设置适配器
        mTabLayout.setupWithViewPager(mViewPager);//将TabLayout和ViewPager关联起来。
        mTabLayout.setTabsFromPagerAdapter(mAdapter);//给Tabs设置适配器
    }


    //ViewPager适配器
    class MyPagerAdapter extends PagerAdapter {
        private List<View> mViewList;

        public MyPagerAdapter(List<View> mViewList) {
            this.mViewList = mViewList;
        }

        @Override
        public int getCount() {
            return mViewList.size();//页卡数
        }

        @Override
        public boolean isViewFromObject(View view, Object object) {
            return view == object;//官方推荐写法
        }

        @Override
        public Object instantiateItem(ViewGroup container, int position) {
            container.addView(mViewList.get(position));//添加页卡
            return mViewList.get(position);
        }

        @Override
        public void destroyItem(ViewGroup container, int position, Object object) {
            container.removeView(mViewList.get(position));//删除页卡
        }

        @Override
        public CharSequence getPageTitle(int position) {
            return mTitleList.get(position);//页卡标题
        }

    }

}

项目页面（我的笔记，可忽略）：

public class SaleRankingActivity extends VolleyActivity {

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

        ActionBarUtil.setup(this, R.string.sale_ranking);

        int position = getIntent().getIntExtra(EnumIntentKey.SELECT_POSITION.toString(), 0);

        TabLayout tabs = (TabLayout) findViewById(R.id.tabs_square);
        ViewPager pager = $(R.id.vp_square);
        pager.setOffscreenPageLimit(2);
        FragmentPagerAdapter adapter = new FragmentPagerAdapter(getSupportFragmentManager()) {
            private String[] titles = getResources().getStringArray(R.array.ranking_type);

            @Override
            public Fragment getItem(int position) {
                if (position == 0) {    // 专场提醒
                    return SaleRankingListFragment.newInstance(0);
                } else {    // 卖家提醒
                    return SaleRankingListFragment.newInstance(1);
                }
            }

            @Override
            public CharSequence getPageTitle(int position) {
                return titles[position];
            }

            @Override
            public int getCount() {
                return titles.length;
            }
        };
        pager.setAdapter(adapter);
        tabs.setupWithViewPager(pager);

        pager.setCurrentItem(position);//判断是从哪跳进来的
    }
}
