第一步首先利用第三方的design中的tablayout

布局文件

<android.support.design.widget.TabLayout    android:id="@+id/tab"    android:layout_width="match_parent"    android:layout_height="wrap_content"    app:tabGravity="center"    app:tabSelectedTextColor="#cc0000"    app:tabTextColor="#000000"    app:tabMode="scrollable"    />

tabGravity居中显示

tabTextColor 不点击时字体的颜色tabSelectedTextColor 点击时字体颜色
tabMode 可滑动


<android.support.v4.view.ViewPager    android:id="@+id/vp"    android:layout_width="match_parent"    android:layout_height="match_parent"/>搭配viewpager使用 实现滑动的效果;List<Fragment> fragments=new ArrayList<>();  fragments.add(new Fragment1());fragments.add(new Fragment2());fragments.add(new Fragment3());fragments.add(new Fragment4());fragments.add(new Fragment5());fragments.add(new Fragment6());fragments.add(new Fragment7());fragments.add(new Fragment8());fragments.add(new Fragment9());fragments.add(new Fragment10());
//将tablayout和viewpager绑定tab.setupWithViewPager(vp)
 
//给viewpager设置适配器

adapter = new MyAdapter(getSupportFragmentManager(),this,fragments);vp.setAdapter(adapter);//自定义适配器类public class MyAdapter extends FragmentPagerAdapter {    private Context context;    private List<Fragment> list;    private String[] title={"社会","国内","国际","娱乐","社会","国内","国际","娱乐","国际","娱乐"};    public MyAdapter(FragmentManager fm, Context context, List<Fragment> list) {        super(fm);        this.context = context;        this.list = list;    }    public MyAdapter(FragmentManager fm) {        super(fm);    }    @Override    public Fragment getItem(int position) {        return list.get(position);    }    @Override    public int getCount() {        return list.size();    }//重写方法实现tablayout和viewpager联动    @Override    public CharSequence getPageTitle(int position) {        return title[position];    }}
