Question

我尝试使用YouTube API在Listview中显示YouTubeThumbnailView，但无法执行此操作。我需要显示文本和视频（如果没有视频，则显示图像），这需要自定义适配器和YouTubeThumbnailView。我知道有一些话题可以公开，但没有办法解决它。（一切都很适合YouTubeThumbnailView）

这是适配器代码：

public class NewsAdapter extends BaseAdapter implements YouTubeThumbnailView.OnInitializedListener {
public static final String TAG = NewsAdapter.class.getSimpleName();

private Context mContext;
private List<News> mListNews;
private Map<View, YouTubeThumbnailLoader> mLoaders;

public NewsAdapter(Context context, List<News> list) {
    this.mListNews = list;
    this.mContext  = context;
    this.mLoaders  = new HashMap<>();
}

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

@Override
public Object getItem(int i) {
    return this.mListNews.get(i);
}

@Override
public long getItemId(int i) {
    return i;
}

@Override
public View getView(int position, View convertView, ViewGroup viewGroup) {
    View v = convertView;
    Holder viewHolder;
    String videoId = mListNews.get(position).youtube_code;

    if (v == null) {
        LayoutInflater li = (LayoutInflater) mContext
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        v = li.inflate(R.layout.item_news, null);
        viewHolder = new Holder(v);

        viewHolder.youTubePlayerView.setTag(videoId);
        viewHolder.youTubePlayerView.initialize(BuildConfigData.getKEY_API(), this);

        v.setTag(viewHolder);
    } else {
        viewHolder = (Holder) v.getTag();
        // 2) and 3) The view is already created...
        YouTubeThumbnailLoader loader = mLoaders.get(viewHolder.youTubePlayerView);
        // ...and is currently being initialized. We store the current videoId in the tag.
        if (loader == null) {
            viewHolder.youTubePlayerView.setTag(videoId);
            // ...and already initialized. Simply set the right videoId on the loader.
        } else {
            viewHolder.youTubePlayerView.setImageBitmap(null);
            loader.setVideo(videoId);
        }
    }

    if(this.mListNews.get(position).title != null) viewHolder.newsTitleTextView.setText(Html.fromHtml(mListNews.get(position).title));
    viewHolder.newsCategoryTextView.setVisibility(View.GONE);

    if(!this.mListNews.get(position).main_picture.isEmpty()) {
        final Holder finalview = viewHolder;

    return v;
}

@Override
public void onInitializationSuccess(YouTubeThumbnailView youTubeThumbnailView, YouTubeThumbnailLoader youTubeThumbnailLoader) {
    String videoId = (String) youTubeThumbnailView.getTag();
    mLoaders.put(youTubeThumbnailView, youTubeThumbnailLoader);
    youTubeThumbnailView.setImageBitmap(null);
    youTubeThumbnailLoader.setVideo(videoId);
}

@Override
public void onInitializationFailure(YouTubeThumbnailView youTubeThumbnailView, YouTubeInitializationResult youTubeInitializationResult) {

}



class Holder {
    ImageView newsImgImageView;
    TextView newsTitleTextView;
    TextView newsCategoryTextView;
    YouTubeThumbnailView youTubePlayerView;

    public Holder(View base) {
        newsImgImageView     = (ImageView) base.findViewById(R.id.news_img);
        newsTitleTextView    = (TextView) base.findViewById(R.id.news_title);
        newsCategoryTextView = (TextView) base.findViewById(R.id.news_category);
        youTubePlayerView    = (YouTubeThumbnailView) base.findViewById(R.id.youtube_player_thumb);
    }
}

这是堆栈：

希望有人可以提供帮助。在此先感谢所有人

如果你需要自定义视图（显示视频，如果存在或显示图像）我认为可能需要将视频视图和图像视频分开使用不同的getView

将您的listView方法替换为getVideoView适配器，并为youtube视频视图创建两个单独的getImageView方法，@Override public View getView(int position, View convertView, ViewGroup viewGroup) { String videoId = mListNews.get(position).youtube_code if (videoId.isEmpty()) { return getVideoView(position, convertView, viewGroup); } else { return getVideoView(position, convertView, viewGroup); } } public View getVideoView(int position, View convertView, ViewGroup viewGroup) { VideoViewHolder viewHolder; if (convertView == null || (convertView != null && convertView.getTag() instanceof VideoViewHolder)) { LayoutInflater li = (LayoutInflater) mContext .getSystemService(Context.LAYOUT_INFLATER_SERVICE); convertView = li.inflate(R.layout.item_news, null); viewHolder = new Holder(v); convertView.setTag(viewHolder); } else { viewHolder = (VideoViewHolder) convertView.getTag(); } viewHolder.youTubePlayerView.setTag(videoId); viewHolder.youTubePlayerView.initialize(BuildConfigData.getKEY_API(), this); // 2) and 3) The view is already created... YouTubeThumbnailLoader loader = mLoaders.get(viewHolder.youTubePlayerView); // ...and is currently being initialized. We store the current videoId in the tag. if (loader == null) { viewHolder.youTubePlayerView.setTag(videoId); // ...and already initialized. Simply set the right videoId on the loader. } else { viewHolder.youTubePlayerView.setImageBitmap(null); loader.setVideo(videoId); } if(this.mListNews.get(position).title != null) { viewHolder.newsTitleTextView.setText(Html.fromHtml(mListNews.get(position).title)); } else { viewHolder.newsCategoryTextView.setVisibility(View.GONE); } return convertView; } public View getImageView(int position, View convertView, ViewGroup viewGroup) { ImageViewHolder viewHolder; if (convertView == null || (convertView != null && convertView.getTag() instanceof ImageViewHolder)) { LayoutInflater li = (LayoutInflater) mContext .getSystemService(Context.LAYOUT_INFLATER_SERVICE); convertView = li.inflate(R.layout.item_news, null); viewHolder = new Holder(v); convertView.setTag(viewHolder); } else { viewHolder = (ImageViewHolder) v.getTag(); } if(this.mListNews.get(position).title != null) { viewHolder.newsTitleTextView.setText(Html.fromHtml(mListNews.get(position).title)); } else { viewHolder.newsCategoryTextView.setVisibility(View.GONE); } if(!this.mListNews.get(position).main_picture.isEmpty()) { final Holder finalview = viewHolder; return v; }图像视图方法

Holder

修改了您的VideoViewHolder课程并创建了ImageViewHolder和class Holder { ImageView newsImgImageView; TextView newsTitleTextView; TextView newsCategoryTextView; YouTubeThumbnailView youTubePlayerView; public Holder(View base) { newsImgImageView = (ImageView) base.findViewById(R.id.news_img); newsTitleTextView = (TextView) base.findViewById(R.id.news_title); newsCategoryTextView = (TextView) base.findViewById(R.id.news_category); youTubePlayerView = (YouTubeThumbnailView) base.findViewById(R.id.youtube_player_thumb); } } class VideoViewHolder extends Holder { YouTubeThumbnailView youTubePlayerView; public Holder(View base) { super(base); youTubePlayerView = (YouTubeThumbnailView) base.findViewById(R.id.youtube_player_thumb); } } class ImageViewHolder extends Holder { ImageView newsImgImageView; public Holder(View base) { super(base); newsImgImageView = (ImageView) base.findViewById(R.id.news_img); } }课程
