Tablayout的使用

//添加导包  com.android.support:design:26.0.0-alpha1

//Mainactivity内容

import java.util.ArrayList;import java.util.List;public class MainActivity extends AppCompatActivity {    private List<String> datas = new ArrayList<String>();    private TabLayout tabLayout;    private ViewPager viewPager;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);

//获取控件        tabLayout = (TabLayout) findViewById(R.id.tas);        viewPager = (ViewPager) findViewById(R.id.vp);//横向滑动的集合        datas.add("推荐");        datas.add("要闻");        datas.add("娱乐");        datas.add("科技");        datas.add("汽车");        datas.add("体育");        datas.add("图片");        datas.add("动漫");        datas.add("社会");        datas.add("游戏");

//适配器        vpsp vpsp = new vpsp(getSupportFragmentManager());        viewPager.setAdapter(vpsp);

//进行关联
        tabLayout.setupWithViewPager(viewPager);

//        tabLayout.setupWithViewPager(viewPager);

//        tabLayout.setTabsFromPagerAdapter(vpsp);        

//虽然过时了但是不能去掉，去掉后        

//如果是滑动操作的话没事，但是使用标签点击的时候就不行了。

//        tabLayout.setTabMode(TabLayout.MODE_SCROLLABLE);        

//tab的模式如果标签多的话用MODE_SCROLLABLE  少的话用MODE_FIXED   

 }    

class vpsp extends FragmentPagerAdapter{

//有参数的构造        

public vpsp(FragmentManager fm) {   

         super(fm);        

}

//返回选项卡的文本 ，，，添加选项卡
        @Override        

public CharSequence getPageTitle(int position) {            

return datas.get(position);        

}

//创建fragment对象并返回
        @Override        

public Fragment getItem(int position) {            

content content = new content();            

Bundle bundle = new Bundle();            

bundle.putString("name",datas.get(position));            

content.setArguments(bundle);            

return content;        }

//返回数量        @Override        public int getCount() {            return datas.size();        }    }}

//Main的布局
