Question

我正在使用 Rrtrofit 处理聊天应用程序。通过关注Sendbird我创建聊天对话活动。问题是我不明白如何显示对话的图像。特别是当聊天应用程序图像可以随机出现时。在博客上显示如果我尝试为发件人和收件人视图设置imageView，但不了解如何处理它。

这是我的RecyclerView.ViewHolder：

UIImage

我可以看到我分别为Sender和Receiver工作，因此以下代码是 SentMessageHolder

public RecyclerView.ViewHolder onCreateViewHolder(final ViewGroup parent, int viewType) {

    View view;
    if (viewType == VIEW_TYPE_MESSAGE_SENT) {
        view = LayoutInflater.from(parent.getContext())
                .inflate(R.layout.item_message_sent, parent, false);
        return new SentMessageHolder(view);

    } else if (viewType == VIEW_TYPE_MESSAGE_RECEIVED){
        view = LayoutInflater.from(parent.getContext())
                .inflate(R.layout.item_message_received, parent, false);
        return new ReceivedMessageHolder(view);
    }
    return null;
}



// Passes the message object to a ViewHolder so that the contents can be bound to UI.
@Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
    Datum2 message = (Datum2) data.get(position);

    switch (holder.getItemViewType()) {
        case VIEW_TYPE_MESSAGE_SENT:
            ((SentMessageHolder) holder).bind(message);

            break;
        case VIEW_TYPE_MESSAGE_RECEIVED:
            ((ReceivedMessageHolder) holder).bind(message);
    }

}

以及我的 ReceivedMessageHolder 是：

    private class SentMessageHolder extends RecyclerView.ViewHolder {
    TextView messageText, timeText;
    String rec_id;
    String content_id;
    int[] ids = new int[100];

    SentMessageHolder(final View itemView) {
        super(itemView);

        messageText = itemView.findViewById(R.id.text_message_body);
        timeText = itemView.findViewById(R.id.text_message_time);
    }
    void bind(Datum2 message) {
        messageText.setText(message.getMsg());

        // Format the stored timestamp into a readable String using method.
        timeText.setText(message.getCreatedAt().getFormatTime());
        content_id = message.getContentId().toString();
        if (! message.getOriginatorId().equals(userID)){
            rec_id.valueOf(message.getOriginatorId());
        }
        else {
            rec_id = null;
        }
    }
}

这是我的图像模态类：

    private class ReceivedMessageHolder extends RecyclerView.ViewHolder {
    TextView messageText, timeText, nameText;

    ImageView profileImage;
    ReceivedMessageHolder(View itemView) {
        super(itemView);

        messageText = itemView.findViewById(R.id.text_message_body);
        timeText = itemView.findViewById(R.id.text_message_time);
        nameText = itemView.findViewById(R.id.text_message_name);
        profileImage =  itemView.findViewById(R.id.image_message_profile);
    }
    void bind(Datum2 message) {
        messageText.setText(message.getMsg());

        // Format the stored timestamp into a readable String using method.
        timeText.setText(message.getCreatedAt().getFormatTime());
        nameText.setText(message.getOriginator().getFullName());

        // Insert the profile image from the URL into the ImageView.
        Glide.with(mContext).load("my website url" + data.get(getLayoutPosition())
                .getOriginator().getAvatar()).apply(RequestOptions.circleCropTransform())
                .into(profileImage);
    }
}

我的json是这样的：

public class Attributes {
@SerializedName("sticker")
@Expose
private String sticker;

@SerializedName("images")
@Expose
private List<String> images;

public String getSticker() {
    return sticker;
}

public void setSticker(String sticker) {
    this.sticker = sticker;
}

public List<String> getImages() {
    return images;
}

public void setImages(List<String> images) {
    this.images = images;
}
}

那么在我的对话中如何检索我的图像呢？需要帮忙。

使用Retrofit在Android中的聊天应用程序的recylerView中显示图像
