android studio视频图片轮播

你可以使用Android Studio中的ViewPager和FragmentPagerAdapter来实现视频和图片的轮播效果。

首先，你需要创建一个ViewPager和一个FragmentPagerAdapter。具体实现可以参考以下代码：

public class MyPagerAdapter extends FragmentPagerAdapter {
    private List<Fragment> fragmentList;

    public MyPagerAdapter(FragmentManager fm, List<Fragment> fragmentList) {
        super(fm);
        this.fragmentList = fragmentList;
    }

    @Override
    public Fragment getItem(int position) {
        return fragmentList.get(position);
    }

    @Override
    public int getCount() {
        return fragmentList.size();
    }
}

然后，你需要创建一个Fragment来展示视频和图片。具体实现可以参考以下代码：

public class MyFragment extends Fragment {
    private int resId;

    public MyFragment(int resId) {
        this.resId = resId;
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_my, container, false);
        ImageView imageView = view.findViewById(R.id.image_view);
        VideoView videoView = view.findViewById(R.id.video_view);
        if (resId == R.drawable.image1 || resId == R.drawable.image2 || resId == R.drawable.image3) {
            imageView.setVisibility(View.VISIBLE);
            videoView.setVisibility(View.GONE);
            imageView.setImageResource(resId);
        } else {
            imageView.setVisibility(View.GONE);
            videoView.setVisibility(View.VISIBLE);
            videoView.setVideoURI(Uri.parse("android.resource://" + getActivity().getPackageName() + "/" + resId));
            videoView.start();
        }
        return view;
    }
}

最后，你需要在Activity中初始化ViewPager并设置Adapter。具体实现可以参考以下代码：

List<Fragment> fragmentList = new ArrayList<>();
fragmentList.add(new MyFragment(R.drawable.image1));
fragmentList.add(new MyFragment(R.drawable.video1));
fragmentList.add(new MyFragment(R.drawable.image2));
fragmentList.add(new MyFragment(R.drawable.video2));
fragmentList.add(new MyFragment(R.drawable.image3));

ViewPager viewPager = findViewById(R.id.view_pager);
MyPagerAdapter adapter = new MyPagerAdapter(getSupportFragmentManager(), fragmentList);
viewPager.setAdapter(adapter);
viewPager.setOffscreenPageLimit(fragmentList.size());

这样，你就可以实现视频和图片的轮播效果了。
