 <android.support.design.widget.TabLayout

//第一步：初始化ViewPager并设置adapter 
 viewPager = (ViewPager) findViewById(R.id.viewpager); 
 viewPager.setAdapter(new MyViewPagerAdapter(getSupportFragmentManager(), fragmentList)); 
 
 //第二步：初始化Tablayout，给ViewPager设置标题（选项卡） 
 tabLayout = (TabLayout) findViewById(R.id.tablayout); 
 
 tabLayout.addTab(tabLayout.newTab().setText("UFC"));//添加tab选项卡 
 tabLayout.addTab(tabLayout.newTab().setText("武林风")); 
 tabLayout.addTab(tabLayout.newTab().setText("昆仑决")); 
 tabLayout.addTab(tabLayout.newTab().setText("荣耀")); 
 tabLayout.addTab(tabLayout.newTab().setText("勇士的崛起")); 
 tabLayout.addTab(tabLayout.newTab().setText("K-1")); 
 
 //第三步：关联ViewPager 
 tabLayout.setupWithViewPager(viewPager); 

//在关联ViewPager之后添加如下代码，前三步不用更改 
 tabLayout.getTabAt(0).setText("UFC"); 
 tabLayout.getTabAt(1).setText("武林风"); 
 tabLayout.getTabAt(2).setText("昆仑决"); 
 tabLayout.getTabAt(3).setText("荣耀"); 
 tabLayout.getTabAt(4).setText("勇士的崛起"); 
 tabLayout.getTabAt(5).setText("K-1");
