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() {
    }
}
