}

Creating a Reply

Call the Replies.Create API to create a reply to a comment.

/**

 * @param fileId File ID.
 * @param commentId Comment ID. 
 */
private Reply createReplies(String fileId, String commentId) {
    Reply replyResponse = null;
    Drive drive = buildDrive();
    try {
        Reply reply = new Reply();
        reply.setDescription("interface test reply");
        reply.setOperate("resolve");
        replyResponse = drive.replies().create(fileId, commentId, reply).setFields("*").execute();
    } catch (Exception ex) {
        Log.e(TAG, "createReplies error: " + ex.toString());
    }
    return replyResponse;
}

Listing Replies

Call the Replies.List API to list replies to a comment.

/**
* List replies to the comment. 
 *
 * @param fileId File ID.

 */
private List<Reply> listReplies(String fileId, String commentId) {
    Drive drive = buildDrive();
    List<Reply> replyResponse = new ArrayList<>();
    String nextCursor = null;
    try {
        Drive.Replies.List listReq = drive.replies().list(fileId, commentId);
        do {
            if (nextCursor != null) {
                listReq.setCursor(nextCursor);
            }
            ReplyList replyList = listReq.setFields("*").execute();
            List<Reply> replies = replyList.getReplies();
            if (replies == null) {
                break;
            }
            replyResponse.addAll(replies);
            nextCursor = replyList.getNextCursor();
        } while (StringUtils.isNullOrEmpty(nextCursor));
    } catch (Exception ex) {
        Log.e(TAG, "listReplies error: " + ex.toString());
    }
    return replyResponse;
}

Obtaining Reply Details

Call the Replies.Get API to obtain reply details.

/**
* Obtain reply details.
 *
 * @param fileId File ID.
 * @param commentId Comment ID. 
 * @param replyId Reply ID. 
 */
private Reply getReplies(String fileId, String commentId, String replyId) {
    Reply reply = null;
    Drive drive = buildDrive();
    try {
        reply = drive.replies().get(fileId, commentId, replyId).setFields("*").execute();
    } catch (Exception ex) {
        Log.e(TAG, "getReplies error: " + ex.toString());
    }
    return reply;
}

Updating a Reply

Call the Replies.Update API to update a reply.

/**    
* Update a reply.
 *     
 * @param fileId File ID. 
 * @param commentId Comment ID. 
 * @param replyId Reply ID. 
 */  
private void updateReplies(String fileId, String commentId, String replyId) {
    Drive drive = buildDrive();
    try {
        Reply reply = new Reply();
        reply.setDescription("interface test reply");
        reply.setOperate("reopen");
        drive.replies().update(fileId, commentId, replyId, reply).execute();
    } catch (Exception ex) {
        Log.e(TAG, "updateReplies error: " + ex.toString());
    }
}

Deleting a Reply

/**

 *     
 * @param fileId File ID. 
 * @param commentId Comment ID. 
 * @param replyId Reply ID. 
 */  
private void deleteReplies(String fileId, String commentId, String replyId) {
    Drive drive = buildDrive();
    try {
        drive.replies().delete(fileId, commentId, replyId).execute();
    } catch (Exception ex) {
        Log.e(TAG, "deleteReplies error: " + ex.toString());
    }
