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

activity_main.xml

 1 <?xml version="1.0" encoding="utf-8"?>

 2 <LinearLayout

 3     xmlns:android="http://schemas.android.com/apk/res/android"

11         android:layout_width="match_parent"

12         />

13     <android.support.v4.view.ViewPager

14         android:id="@+id/pager"

15         android:layout_width="fill_parent"

16         android:layout_height="0dp"

17         android:layout_weight="1"

19 </LinearLayout>

MainActivity.java

 1 public class MainActivity extends FragmentActivity {

 9

10         FragmentPagerAdapter adapter = new GoogleMusicAdapter(getSupportFragmentManager());

11

12         ViewPager pager = (ViewPager)findViewById(R.id.pager);

13         pager.setAdapter(adapter);

14

15         TabPageIndicator indicator = (TabPageIndicator)findViewById(R.id.indicator);

16         indicator.setViewPager(pager);

17     }

18

19     class GoogleMusicAdapter extends FragmentPagerAdapter {

21             super(fm);

22             list.add(new TestFragment(CONTENT[0]));

23             list.add(new TestFragment(CONTENT[1]));

24             list.add(new TestFragment(CONTENT[2]));

25             list.add(new TestFragment(CONTENT[3]));

26             list.add(new TestFragment(CONTENT[4]));

28         }

30         @Override

33         }

34

35         @Override

36         public CharSequence getPageTitle(int position) {

37             return CONTENT[position % CONTENT.length].toUpperCase();

40         @Override

41         public int getCount() {

42             return CONTENT.length;

43         }

44     }

45 }

Fragment.Java

 1 public final class TestFragment extends Fragment {

 2  

 3     private String s;

 4

 5     public TestFragment(String s)

 6     {

 7         this.s=s;

 8     }

 9    

10     @Override

11     public View onCreateView(LayoutInflater inflater,  ViewGroup container,  Bundle savedInstanceState) {

12

13         return inflater.inflate(R.layout.fragment_news, container, false);

14     }

15

16     @Override

17     public void onActivityCreated( Bundle savedInstanceState) {

18         // TODO Auto-generated method stub

20         View view=getView();

21         TextView te=(TextView)view.findViewById(R.id.textView1);

22         te.setText(s);
