Android studio列表视频播放器

以下是一个简单的 Android Studio 列表视频播放器代码示例：

1. 在布局文件中，添加一个 RecyclerView 控件：

<androidx.recyclerview.widget.RecyclerView
    android:id="@+id/recyclerView"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

2. 创建一个 VideoAdapter 类来绑定数据和视图：

public class VideoAdapter extends RecyclerView.Adapter<VideoAdapter.VideoViewHolder> {
    private List<String> videoUrls;

    public VideoAdapter(List<String> videoUrls) {
        this.videoUrls = videoUrls;
    }

    @NonNull
    @Override
    public VideoViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
        View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_video, parent, false);
        return new VideoViewHolder(view);
    }

    @Override
    public void onBindViewHolder(@NonNull VideoViewHolder holder, int position) {
        String videoUrl = videoUrls.get(position);
        holder.videoView.setVideoPath(videoUrl);
    }

    @Override
    public int getItemCount() {
        return videoUrls.size();
    }

    public class VideoViewHolder extends RecyclerView.ViewHolder {
        VideoView videoView;
        Button playButton;

        public VideoViewHolder(@NonNull View itemView) {
            super(itemView);
            videoView = itemView.findViewById(R.id.videoView);
            playButton = itemView.findViewById(R.id.playButton);

            playButton.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    if (videoView.isPlaying()) {
                        videoView.pause();
                        playButton.setText("Play");
                    } else {
                        videoView.start();
                        playButton.setText("Pause");
                    }
                }
            });

            videoView.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
                @Override
                public void onCompletion(MediaPlayer mp) {
                    playButton.setText("Play");
                }
            });
        }
    }
}

3. 在布局文件中，创建一个 item_video.xml 布局文件，用于显示每个视频项：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="200dp">

    <VideoView
        android:id="@+id/videoView"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

    <Button
        android:id="@+id/playButton"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Play"
        android:layout_centerInParent="true" />

</RelativeLayout>

4. 在代码中，初始化 RecyclerView 和 VideoAdapter，并设置布局管理器和适配器：

List<String> videoUrls = new ArrayList<>();
videoUrls.add("your_video_url_1_here");
videoUrls.add("your_video_url_2_here");
// add more video urls as needed

RecyclerView recyclerView = findViewById(R.id.recyclerView);
recyclerView.setLayoutManager(new LinearLayoutManager(this));
VideoAdapter videoAdapter = new VideoAdapter(videoUrls);
recyclerView.setAdapter(videoAdapter);

注意：在使用 RecyclerView 播放在线视频时，需要在 Manifest 文件中添加网络权限：

<uses-permission android:name="android.permission.INTERNET" />
