Layout

howerver, StickHeaderViewPager must have two childViews,frist childView will scroll with viewpager,second will tick on the top.

  <com.library.StickHeaderViewPager
        android:id="@+id/shvp_content"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_below="@id/toolbar">
        
        <ImageView
            android:id="@+id/iv_headerImage"
            android:layout_width="match_parent"
            android:layout_height="200dp"
            android:src="@drawable/bg_simple_header"
            android:scaleType="centerInside"/>

        <TextView
            android:id="@+id/tv_stick"
            android:layout_width="match_parent"
            android:layout_height="50dp"
            android:gravity="center_vertical"
            android:paddingLeft="10dp"
            android:background="#657232"
            android:text="This is a simple demo!"
            />  
 </com.library.StickHeaderViewPager>

Fragment

and then create a fragment which extends ScrollFragment.it's easy. if you need a ListView ,please make your fragment extends StickHeaderListFragment,if you want to create a webView ,just extends StickHeaderWebViewFragment. even dot't need to inflate view by yourself. for a example.

  public class ListViewSimpleFragment extends StickHeaderListFragment {

    public static ListViewSimpleFragment newInstance() {
        ListViewSimpleFragment fragment = new ListViewSimpleFragment();
        return fragment;
    }

    public static ListViewSimpleFragment newInstance(String title) {
        ListViewSimpleFragment fragment = new ListViewSimpleFragment();
        fragment.setTitle(title);
        return fragment;
    }

    @Override
    public void bindData() {
        setAdapter();
    }

    public void setAdapter() {
        if (getActivity() == null) return;

        int size = 100;
        String[] stringArray = new String[size];
        for (int i = 0; i < size; ++i) {
            stringArray[i] = ""+i;
        }

        ArrayAdapter<String> adapter = new ArrayAdapter<>(getActivity(), android.R.layout.simple_list_item_1, stringArray);

        getScrollView().setAdapter(adapter);
    }
}

Activity

last step,init your StickHeaderViewPager with StickHeaderViewPagerBuilder.that's all. by the way,activity should extends FragmentActivity or AppCompatActivity.

  StickHeaderViewPagerBuilder.stickTo((StickHeaderViewPager) findViewById(R.id.shvp_content))
                .setFragmentManager(getSupportFragmentManager())
                .addScrollFragments(ListViewSimpleFragment.newInstance("ListView"))
                .notifyData();
