推荐答案

这不是ViewPager的工作方式.您使用 ViewPager ="http://developer.android.com/reference/android/support/v4/view/PagerAdapter.html" rel ="nofollow"> PagerAdapter .您的ListView将包含在PagerAdapter创建的Fragment中.

This is not how ViewPager works. You feed the pages to ViewPager with a PagerAdapter. Your ListView will be contained within a Fragment created by the PagerAdapter.

在布局中:

<android.support.v4.view.ViewPager
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:id="@+id/home_pannels_pager" />

在具有以下布局的FragmentActivity中:

In the FragmentActivity with this layout:

ViewPager pager = (ViewPager) findViewById(R.id.viewPager);
pager.setAdapter(new PagerAdapter(getSupportFragmentManager()));

类似PagerAdapter的示例:

Example of simle PagerAdapter:

public class PagerAdapter extends FragmentPagerAdapter {

    public FrontPageAdapter(FragmentManager Fm) {
        super(Fm);
    }

    @Override
    public Fragment getItem(int position) {
        Bundle arguments = new Bundle();
        arguments.putInt("position", position);
        FragmentPage fragment = new FragmentPage();
        fragment.setArguments(arguments);
        return fragment;
    }

    @Override
    public int getCount() {
        // return count of pages
        return 3;
    }
}

FragmentPage示例:

Example of FragmentPage:

public class FragmentPage extends Fragment {

    public FragmentPage() {}

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_frontpage, container, false);
        // probably cast to ViewGroup and find your ListView

        Bundle arguments = getArguments();
        int position = b.getInt("position");

        return view;
    }
}
