Question

我有ViewPagerwitch在第一页上显示一些图像，但在第二页上我想在listview中显示一些图像，混淆如何在布局中进行单独的页面设置。以下是添加页面的ViewPager方法

// Instantiate a ViewPager and a PagerAdapter.
    mPager = (ViewPager) findViewById(R.id.pager);
    mPagerAdapter = new ScreenSlidePagerAdapter(getFragmentManager());
    mPager.setAdapter(mPagerAdapter);
    mPager.setOnPageChangeListener(new ViewPager.SimpleOnPageChangeListener() {
        @Override
        public void onPageSelected(int position) {

            invalidateOptionsMenu();
        }
    });

这里是适配器

 private class ScreenSlidePagerAdapter extends FragmentStatePagerAdapter {
    public ScreenSlidePagerAdapter(FragmentManager fm) {
        super(fm);
    }

    @Override
    public Fragment getItem(int position) {
        return ScreenSlidePageFragment.create(position);
    }

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

屏幕滑块ViewPager类

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

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    // Inflate the layout containing a title and body text.
    ViewGroup rootView = (ViewGroup) inflater
            .inflate(R.layout.fragment_screen_slide_page, container, false);

    // Set the title view to show the page number.
    ((TextView) rootView.findViewById(android.R.id.text1)).setText(
            getString(R.string.title_template_step, mPageNumber + 1));

    return rootView;
}

您可以在ScreenSlidePagerAdapter更改getItem。在ScreenSlideSecondPageFragment中，您为第二页扩充布局。

        @Override
        public Fragment getItem(int position) {

            switch (position) {               
            case 0: 
                return ScreenSlidePageFragment.create(position);
            case 1: 
                return ScreenSlideSecondPageFragment.create(position);

            default:
                return null;
            }
        }

我想在ViewPager的第二页中添加Listview在android
