一、文档说明

基于网易云信的IM，接入云叮当红包SDK实现App快速集成发单聊红包、发群聊红包、拆红包并查看交易记录等功能.

在阅读下面内容之前我们假设你有一定的android开发能力并且你的项目中已经接入过网易云信IM和云叮当红包.或者完全当做教程。

二、集成流程详解

1. 在app的application类中初始化网易云信,UIkit,云叮当红包

   public class MyApplication extends Application {
   
       public void onCreate() {
   
           super.onCreate();
   
           // ... your codes
   
           NIMClient.init(this, null, null);
   
           // ... your codes
   
           if (inMainProcess()) {
           // 初始化UIKit模块
               initUIKit();
               NIMClient.getService(MsgService.class).registerCustomAttachmentParser(new CustomAttachParser());
               NimUIKit.registerMsgItemViewHolder(fghGuessAttachment.class,fghSessionHelper.class);
           }
   
           //初始化云叮当红包模块
           RedPacket.initReaPacket(this, new AppSecretCallBack(), new UseOrderInfoLinster());
   
           //打开云叮当红包日志
           RedPacketLog.DEBUG = true;
       }
   }
   

2. 用户登陆时载入用户信息

   RedPacket.initReaPacket(String account, String nickName, String serialNumber);
   

3. 新建一个PacketAction对象

   public class PacketAction extends BaseAction {
   
       public PacketAction() {
           //图标和名称对应的ID
           super(R.drawable.redpacket, R.string.input_panel_redpacket);
       }
   
       @Override
       public void onClick() {
           //点击事件,调用发红包页面(当然,你也可以在其他地方调用起发红包界面)
            RedPacket.sendPacket(Context context, 1, String receivedUID, String );
       }
   }
   

4. 在MessageFragment类里面添加PacketAction

   // 操作面板集合
   protected List<BaseAction> getActionList() {
       List<BaseAction> actions = new ArrayList<>();
       //......
       actions.add(new PacketAction());
   
       if (customization != null &&  customization.actions != null) {
           actions.addAll(customization.actions);
       }
       return actions;
   }
   

   这时,你就能在操作面板中看到发红包的入口了

   接下来,我们要自定义网易云信的消息

5. 定义一个红包消息的类型

   public interface CustomAttachmentType {
       // 多端统一
       int Guess = 1;
       int SnapChat = 2;
       int Sticker = 3;
       int RTS = 4;
       int SHARE  = 5;//自定义
   }
   

6. 定义一个红包消息的基类

   public abstract class CustomAttachment implements MsgAttachment {
   
       protected int type;
   
       CustomAttachment(int type) {
           this.type = type;
       }
   
       public void fromJson(JSONObject data) {
           if (data != null) {
   
               parseData(data);
   
           }
       }
   
       @Override
       public String toJson(boolean send) {
           return CustomAttachParser.packData(type, packData());
       }
   
       public int getType() {
           return type;
       }
   
       protected abstract void parseData(JSONObject data);
   
       protected abstract JSONObject packData();
   }
   

7. 继承这个基类，解析消息

   public class PacketAttachment extends CustomAttachment {
   
   
       private String packetID;
       private String packetType;
   
   
       protected int type;
   
   
       public PacketAttachment() {
           super(CustomAttachmentType.SHARE);
   
       }
   
       public PacketAttachment(String str) {
           this();
       }
   
       @Override
       protected void parseData(JSONObject data) {
           packetID = data.getString("packetID");
           packetType = data.getString("packetType");
       }
   
       @Override
       public JSONObject packData() {
           JSONObject data = new JSONObject();
           data.put("packetID",packetID);
           data.put("packetType",packetType);
           return data;
       }
   
       public String getPacketType() {
           return packetType;
       }
   
       public void setPacketType(String packetType) {
           this.packetType = packetType;
       }
   
       public String getPacketID() {
           return packetID;
       }
   
       public void setPacketID(String packetID) {
           this.packetID = packetID;
       }
   
   }
   

8. 实现红包消息的解析器

   // 在Application初始化中注册自定义消息附件解析器 
   NIMClient.getService(MsgService.class).registerCustomAttachmentParser(new CustomAttachParser());
   
   public class CustomAttachParser implements MsgAttachmentParser {
   
       private static final String KEY_TYPE = "type";
       private static final String KEY_DATA = "data";
   
       @Override
       public MsgAttachment parse(String json) {
           CustomAttachment attachment = null;
           try {
               JSONObject object = JSON.parseObject(json);
               int type = object.getInteger(KEY_TYPE);
               JSONObject data = object.getJSONObject(KEY_DATA);
               switch (type) {
                   case CustomAttachmentType.Guess:
                       attachment = new PacketAttachment();
                       break;
                   default:
                       attachment = new DefaultCustomAttachment();
                       break;
               }
   
               if (attachment != null) {
                   attachment.fromJson(data);
               }
           } catch (Exception e) {
           }
   
           return attachment;
       }
   
       public static String packData(int type, JSONObject data) {
           JSONObject object = new JSONObject();
           object.put(KEY_TYPE, type);
           if (data != null) {
               object.put(KEY_DATA, data);
           }
   
           return object.toJSONString();
       }
   } 
   

9. 将自定义消息展示UI上

   public class PacketSessionHelper extends MsgViewHolderBase{
   
       private PacketAttachment attachment;
   
       @Override
       protected int getContentResId() {
           return R.layout.abcdefg;
       }
   
       @Override
       protected void inflateContentView() {
   
           //你的代码
   
       }
   
       @Override
       protected void bindContentView() {
   
           //你的代码
       }
   
       //若是要自己修改气泡背景
       // 当是发送出去的消息时，内容区域背景的drawable id
       @Override
       protected int rightBackground() {
           return com.netease.nim.uikit.R.drawable.nim_message_item_right_selector;
       }
   
   }
   

10. 发送红包消息

    在activity中重写onActivityResult方法

     @Override
        protected void onActivityResult(int requestCode, int resultCode, Intent data) {
            switch (requestCode) {
                case 1:
                    switch (resultCode) {
                        case 1:
                           PacketAttachment attachment = new PacketAttachment();
                           IMMessage message;
                           if (getContainer() != null && getContainer().sessionType == SessionTypeEnum.ChatRoom) {
                                message = ChatRoomMessageBuilder.createChatRoomCustomMessage(getAccount(), attachment);
                           } else {
                                message = MessageBuilder.createCustomMessage(getAccount(), getSessionType(), attachment);
                           }
                           sendMessage(message);
                            break;
                        default:
                            break;
                    }
                    break;
                default:
                    break;
            }
            super.onActivityResult(requestCode, resultCode, data);
        }
    

11. 在app的application类中注册消息解析器和服务

    NIMClient.getService(MsgService.class).registerCustomAttachmentParser(new CustomAttachParser());
    NimUIKit.registerMsgItemViewHolder(PacketAttachment.class,PacketSessionHelper.class);
    

12. 在PacketSessionHelper中重写onItemClick方法,实现开红包功能

    // 内容区域点击事件响应处理。
    @Override
    protected void onItemClick() {
        RedPacket.openPacket(FragmentActivity activity, 
                          String platRpNo,
                          @Nullable String outReceiveNo,
                          @Nullable String outGroupId,
                          new RedPacketCallBack callBack()){
            //代码省略
        };
    }
