我想在 android 的 ViewPager 的第二页中添加 Listview

Question

我有 ViewPagerwitch 在第一页显示一些图像，但在第二页我想在列表视图中显示一些图像，对如何在布局中进行单独的页面设置感到困惑。这是用于添加页面的 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 class

  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;
}

Answer 1

您可以在 ScreenSlidePagerAdapter 中更改 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;
    }
}
