ViewPagerIndicator+viewpager的简单使用，不需要导入Library包

ViewPagerIndicator作为一款分页指标小部件兼容ViewPager，封装上做得非常不错，目前已为众多知名应用所使用。

ViewPagerIndicator+viewpager实现如下效果：（注：不需要导入或引入啥包就可实现）

六个类就可实现上图效果

MainActivity.java

 public class MainActivity extends FragmentActivity {
     private static final String[] CONTENT = new String[] { "推荐", "热点", "视频", "本地", "科技", "健康" };
 
     private List<Fragment> list=new ArrayList<Fragment>();
     @Override
     protected void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         setContentView(R.layout.activity_main);
 
         FragmentPagerAdapter adapter = new GoogleMusicAdapter(getSupportFragmentManager());
 
         ViewPager pager = (ViewPager)findViewById(R.id.pager);
         pager.setAdapter(adapter);
 
         TabPageIndicator indicator = (TabPageIndicator)findViewById(R.id.indicator);
         indicator.setViewPager(pager);
     }
 
     class GoogleMusicAdapter extends FragmentPagerAdapter {
         public GoogleMusicAdapter(FragmentManager fm) {
             super(fm);
             list.add(new TestFragment(CONTENT[0]));
             list.add(new TestFragment(CONTENT[1]));
             list.add(new TestFragment(CONTENT[2]));
             list.add(new TestFragment(CONTENT[3]));
             list.add(new TestFragment(CONTENT[4]));
             list.add(new TestFragment(CONTENT[5]));
         }
 
         @Override
         public Fragment getItem(int position) {
             return list.get(position);
         }
 
         @Override
         public CharSequence getPageTitle(int position) {
             return CONTENT[position % CONTENT.length].toUpperCase();
         }
 
         @Override
         public int getCount() {
             return CONTENT.length;
         }
     }
 }

Fragment.Java

 public final class TestFragment extends Fragment {
 
     private String s;
 
     public TestFragment(String s)
     {
         this.s=s;
     }
 
     @Override
     public View onCreateView(LayoutInflater inflater,  ViewGroup container,  Bundle savedInstanceState) {
 
         return inflater.inflate(R.layout.fragment_news, container, false);
     }
 
     @Override
     public void onActivityCreated( Bundle savedInstanceState) {
         // TODO Auto-generated method stub
         super.onActivityCreated(savedInstanceState);
         View view=getView();
         TextView te=(TextView)view.findViewById(R.id.textView1);
         te.setText(s);
     }
 
     public void initView() {
     }
 }
