Question

PageAdapter：

class SampleFragmentPagerAdapter extends FragmentPagerAdapter {

private int PAGE_COUNT = 3;
private String tabTitles[];

public SampleFragmentPagerAdapter(FragmentManager fm, String[] categorie) {
    super(fm);
    PAGE_COUNT = categorie.length;
    tabTitles = new String[categorie.length];

    for(int i = 0; i < categorie.length; i++){
        tabTitles[i] = categorie[i];
    }
}

@Override
public int getCount() {
    return PAGE_COUNT;
}

@Override
public Fragment getItem(int position) {
    return Pagina.newInstance(position + 1);
}

@Override
public CharSequence getPageTitle(int position) {
    // Generate title based on item position
    return tabTitles[position];
}
}

片段活动：

public class Pagina extends Fragment {
private int mPage;
public static final String ARG_PAGE = "ARG_PAGE";

public static Pagina newInstance(int page) {
    Bundle args = new Bundle();
    args.putInt(ARG_PAGE, page);
    Pagina fragment = new Pagina();
    fragment.setArguments(args);
    return fragment;
}

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    mPage = getArguments().getInt(ARG_PAGE);
}

// Inflate the fragment layout we defined above for this fragment
// Set the associated text for the title
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.fragment_pagina, container, false);
    //TextView tvTitle = (TextView) view.findViewById(R.id.tvTitle);
    //tvTitle.setText("Fragment #" + mPage);
    Log.e("STATO", "CI SIAMOOO");
    return view;

如何从getSecondScrollView调用方法SampleFragmentPagerAdapter？ 我正在使用这个：https://github.com/jpardogo/PagerSlidingTabStrip 我需要片段内的方法来获取一些视图 抱歉英语不好，我是意大利人：D
