Simple use of ViewPagerIndicator+viewpager, no need to import Library package

As a paging indicator widget, ViewPagerIndicator is compatible with ViewPager. It has done a very good job in packaging and has been used by many well-known applications.

ViewPagerIndicator+viewpager achieves the following effects: (Note: It can be achieved without importing or introducing any package)

      

Six classes can achieve the above effect

activity_main.xml

 

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="fill_parent">

    <com.viewpagerindicator.TabPageIndicator
        android:id="@+id/indicator"
        android:layout_height="wrap_content"
        android:layout_width="match_parent"
        />
    <android.support.v4.view.ViewPager
        android:id="@+id/pager"
        android:layout_width="fill_parent"
        android:layout_height="0dp"
        android:layout_weight="1"
        />
</LinearLayout>

MainActivity.java

 

public class MainActivity extends FragmentActivity {
    private static final String[] CONTENT = new String[] { "recommended", "hot spot", "video", "local", "tech", "health" };

    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() {
    }
}
