如何在recyclerview中以不同的视图显示视频和图像？

Question

在此处输入图像描述我想仅使用一个回收视图适配器以单独的水平视图显示图像和视频。 我有两个按钮（图像和视频）。 拍摄照片时，我必须在一个循环视图中进行显示，就像视频一样。 录制视频后，我想存储在另一个ScrollView中，但是我想使用相同的回收适配器。

if (caseSheetDao.getDataTypesheet().equals("camera")) {

    holder.mCamera.setVisibility(View.VISIBLE);
    holder.mVideoView.setVisibility(View.GONE);
    holder.mVideoplay.setVisibility(View.GONE);
    holder.mFramecase.setVisibility(View.GONE);
    holder.mAudiolayout.setVisibility(View.GONE);

    holder.mCamera.setImageURI(Uri.parse(Environment.getExternalStorageDirectory().getAbsolutePath() + File.separator + caseSheetDao.getUrisheet()));
    Log.i(TAG,"Image Path : "+Environment.getExternalStorageDirectory().getAbsolutePath() + File.separator + caseSheetDao.getUrisheet());
}

if (caseSheetDao.getDataTypesheet().equals("video")) {

    holder.mCamera.setVisibility(View.GONE);
    holder.mAudiolayout.setVisibility(View.GONE);
    holder.mFramecase.setVisibility(View.VISIBLE);
    holder.mVideoView.setVisibility(View.VISIBLE);
    holder.mVideoplay.setVisibility(View.VISIBLE);

//  Glide.with(context)
//      .load(Environment.getExternalStorageDirectory().getAbsolutePath() + File.separator + caseSheetDao.getUrisheet()) // or URI/path
//      .into(holder.mVideoView);

    Log.i(TAG," Video Path : "+Environment.getExternalStorageDirectory().getAbsolutePath() + File.separator + caseSheetDao.getUrisheet());
    holder.mVideoplay.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Intent intent = new Intent();
            intent.setAction(android.content.Intent.ACTION_VIEW);
            intent.setDataAndType(Uri.parse(Environment.getExternalStorageDirectory().getAbsolutePath() + File.separator + caseSheetDao.getUrisheet()), "video/*");
            context.startActivity(intent);
        }
    });

}

像这样 ：

public class Content {
    boolean isVideo;

    public Content(boolean isVideo) {
        this.isVideo = isVideo;
    }

    public boolean isVideo() {
        return isVideo;
    }

    public void setVideo(boolean video) {
        isVideo = video;
    }
}



public class CustomAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder>{

    private static final int IS_VIDEO = 0;
    private static final int IS_IMAGE = 1;
    private List<Content> items;

    public CustomAdapter(List<Content> items) {
        this.items = items;
    }

    public void refresh(List<Content> items) {
        this.items = items;
        notifyDataSetChanged();
    }

    @Override
    public int getItemViewType(int position) {
        if(items.get(position).isVideo){
            return IS_VIDEO;
        }else{
            return IS_IMAGE;
        }
    }

    @Override
    public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        if(viewType == IS_VIDEO){
            return new VideoViewHolder(LayoutInflater.from(parent.getContext()).inflate(R.layout.viewholder_video, parent, false));
        }
        else {
            return new ImageViewHolder(LayoutInflater.from(parent.getContext()).inflate(R.layout.viewholder_image, parent, false));
        }
    }



    @Override
    public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
        if(holder instanceof ImageViewHolder){
            onBindImageViewHolder((ImageViewHolder) holder, position);
        }
        else{
            onBindVideoViewHolder((VideoViewHolder) holder, position);
        }
    }

    private void onBindImageViewHolder(ImageViewHolder holder, int position) {

    }

    private void onBindVideoViewHolder(VideoViewHolder holder, int position) {

    }

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


    public class ImageViewHolder extends RecyclerView.ViewHolder {

        public ImageViewHolder(View itemView) {
            super(itemView);
        }

    }

    public class VideoViewHolder extends RecyclerView.ViewHolder {

        public VideoViewHolder(View itemView) {
            super(itemView);
        }

    }
}
