当我在 Recyclerview 中将视频播放到 VideoView 时，当我滚动时，它会在 x 轴上旋转

Question

我有一个问题。我在 recyclerview 中放了一个 videoview，当我在我的 phone 中查看它时，视频效果非常好，有时它会在 x 轴上旋转 260°向下滚动，但我也有 imageview，它工作正常。

抱歉，我是 android 的新人，我在互联网上搜索信息，但我找不到答案

我更新了 gradle 并使用了 androidx 资源，这改变了我的代码中的所有内容，但我可以解决所有问题.. 除了一。代码可以在我的设备上正常安装，但是当我尝试运行它时，在 run console 中显示此错误

为了尝试找到解决您问题的方法，我最终重新创建了您的项目。仍然不确定为什么您的 videoView 不工作。我认为这要么与使用支持库有关，要么与 recyclerView 中的 hiding/showing 视图逻辑有关。

我建议远离支持库，即 android.support.v7.widget.CardView 因为它们不再受支持并且已知有错误并迁移到 androidx androidx.cardview.widget.CardView.

这是我的 onBindViewHolder 在我的 recyclerView 适配器中

@Override
public void onBindViewHolder(ViewHolder holder, int position) {

    final CardView cd = holder.card;
    final LinearLayout postCard = holder.postCard;
    final ImageView imageView = holder.imageTime;
    final VideoView videoTime = holder.videoTime;

    // Hide both image and video views
    imageView.setVisibility(View.GONE);
    videoTime.setVisibility(View.GONE);

    videoTime.stopPlayback(); // stop play back if view has been reused

    /*
    Demo media Urls contains mp4 and jpg
    List<String> mediaUrls = Arrays.asList("https://funnymemes.funnyjunk.com/movies/Meme_042a09_6211432.mp4",
                                     "https://memeworld.funnyjunk.com/pictures/Avaricious+preparatory+mitigated+kingfisher_c80ce6_7780034.jpg",
                                     "https://funnymemes.funnyjunk.com/movies/Meme_7a7f88_6211432.mp4");
     */


    // returns string used to distinguish the type of media (mp4,jpg)
    String mediaType = mediaUrls.get(position).substring(mediaUrls.get(position).length() - 3); // return last three chars from the url


    switch (mediaType) {
        case "mp4":
            videoTime.setVisibility(View.VISIBLE);
            Uri video = Uri.parse(mediaUrls.get(position));
            videoTime.setVideoURI(video);
            videoTime.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
                @Override
                public void onPrepared(MediaPlayer mp) {
                    mp.setLooping(true);
                    videoTime.start();
                }
            });
            break;
        case "jpg":
            imageView.setVisibility(View.VISIBLE);
            // use picasso for async request for images
            Picasso.get()
                    .load(mediaUrls.get(position))
                    .error(R.drawable.ic_image)
                    .into(imageView);
            break;
        default:
            Log.e("Unknown Media Type ",mediaType);
            break;
    }
}

然后不要忘记将库添加到项目中 Gradle。

implementation 'com.squareup.picasso:picasso:2.71828'
implementation "androidx.recyclerview:recyclerview:1.1.0"
implementation 'androidx.cardview:cardview:1.0.0'
