环信红包接入文档

新开商户可免费发送累计5000元总额的红包，超过5000元后，红包功能自动关闭，直到商户付费购买增值服务“红包功能”后，该功能重新开启，购买增值服务请咨询环信商务经理。

1.redpacketlibrary，在环信SDK的基础上提供了收发红包和零钱的功能。

2.环信官方版Demo已默认集成红包功能，可以直接下载试用。

libs ：包含了集成红包功能所依赖的jar包。(红包使用了glide库做图片加载，由于已经依赖了easeui这里不重复添加)

res ：包含了红包SDK和聊天页面中的资源文件。（红包SDK相关以rp开头，聊天页面相关以em开头）

utils ：封装了收发红包的相关方法。

widget ：聊天界面中的红包以及领取红包后的chatrow。

RedPacketConstant.java 红包功能需要的常量。

注意: 由于RedPacketUtil类中使用了环信SDK中相关方法，redpacketlibrary依赖了easeui。

1.添加对红包工程的依赖

ChatDemo的build.gradle中

dependencies {
        compile project(':redpacketlibrary')
        compile project(':EaseUI')
        compile fileTree(dir: 'libs', include: '*.jar', exclude: 'android-support-multidex.jar')
     }

ChatDemo的setting.gradle中

include ':EaseUI', ':redpacketlibrary'

2.ChatDemo清单文件中注册红包相关组件

<uses-sdk
            android:minSdkVersion="9"
            android:targetSdkVersion="19"
            tools:overrideLibrary="com.easemob.redpacketui"
        />
        
    <!--红包相关界面start-->
        <activity
            android:name="com.easemob.redpacketui.ui.activity.RPRedPacketActivity"
            android:screenOrientation="portrait"
            android:theme="@style/horizontal_slide"
            android:windowSoftInputMode="adjustPan|stateVisible"
            />

        <activity
            android:name="com.easemob.redpacketui.ui.activity.RPDetailActivity"
            android:screenOrientation="portrait"
            android:theme="@style/horizontal_slide"
            android:windowSoftInputMode="adjustPan"
            />

        <activity
            android:name="com.easemob.redpacketui.ui.activity.RPRecordActivity"
            android:screenOrientation="portrait"
            android:theme="@style/horizontal_slide"
            android:windowSoftInputMode="adjustPan"
            />

        <activity
            android:name="com.easemob.redpacketui.ui.activity.RPWebViewActivity"
            android:screenOrientation="portrait"
            android:theme="@style/horizontal_slide"
            android:windowSoftInputMode="adjustResize|stateHidden"
            />
        <activity
            android:name="com.easemob.redpacketui.ui.activity.RPChangeActivity"
            android:configChanges="orientation|keyboardHidden|screenSize"
            android:screenOrientation="portrait"
            android:theme="@style/horizontal_slide"
            android:windowSoftInputMode="adjustResize|stateHidden"
            />

        <activity
            android:name="com.easemob.redpacketui.ui.activity.RPBankCardActivity"
            android:screenOrientation="portrait"
            android:theme="@style/horizontal_slide"
            android:windowSoftInputMode="adjustPan|stateHidden"
            />

        <activity
            android:name="com.easemob.redpacketui.ui.activity.RPGroupMemberActivity"
            android:screenOrientation="portrait"

            android:exported="false"
            android:screenOrientation="behind"
            android:windowSoftInputMode="adjustResize|stateHidden"
            />
        <!--红包相关界面end-->

3.DemoApplication初始化红包上下文

import com.easemob.redpacketsdk.RedPacket;
    
    @Override
    public void onCreate() {
        super.onCreate();
        RedPacket.getInstance().initContext(applicationContext);
        //打开Log开关 正式发布时请关闭
        RedPacket.getInstance().setDebugMode(true);
    }

4.ChatFragment中增加收发红包的功能

添加红包相关常量

private static final int MESSAGE_TYPE_RECV_RED_PACKET = 5;
    
    private static final int MESSAGE_TYPE_SEND_RED_PACKET = 6;
    
    private static final int MESSAGE_TYPE_SEND_RED_PACKET_ACK = 7;
    
    private static final int MESSAGE_TYPE_RECV_RED_PACKET_ACK = 8;
    
    private static final int ITEM_RED_PACKET = 16;
    
    private static final int REQUEST_CODE_SEND_RED_PACKET = 15;

添加红包入口

@Override
    protected void registerExtendMenuItem() {
        //demo这里不覆盖基类已经注册的item,item点击listener沿用基类的
        super.registerExtendMenuItem();
        //聊天室暂时不支持红包功能
        if (chatType != Constant.CHATTYPE_CHATROOM) {
            inputMenu.registerExtendMenuItem(R.string.attach_red_packet, R.drawable.em_chat_red_packet_selector, ITEM_RED_PACKET, extendMenuItemClickListener);
        }
    }

添加自定义chatrow到CustomChatRowProvider，详见ChatFragment中的CustomChatRowProvider。
ContextMenuActivity的onCreate(）中屏蔽红包消息的转发和撤回功能。

if (type == EMMessage.Type.TXT.ordinal()) {
            if(message.getBooleanAttribute(Constant.MESSAGE_ATTR_IS_VIDEO_CALL, false) ||
                    message.getBooleanAttribute(Constant.MESSAGE_ATTR_IS_VOICE_CALL, false)
                    || message.getBooleanAttribute(RedPacketConstant.MESSAGE_ATTR_IS_RED_PACKET_MESSAGE, false)){
                setContentView(R.layout.em_context_menu_for_location);
            }
        }
        
     if (message.direct == EMMessage.Direct.RECEIVE || message.getChatType() == EMMessage.ChatType.ChatRoom
	        //red packet code : 屏蔽红包消息的撤回功能
			|| message.getBooleanAttribute(RedPacketConstant.MESSAGE_ATTR_IS_RED_PACKET_MESSAGE, false)) {
			//end of red packet code
			View view = findViewById(R.id.text_revoke);
			if(view != null){
			    view.setVisibility(View.GONE);
			}
		}

进入发红包页面

@Override
    public boolean onExtendMenuItemClick(int itemId, View view) {
        switch (itemId) {
        ...
        case ITEM_RED_PACKET:
            RedPacketUtils.startRedPacketActivityForResult(this, chatType, toChatUsername, REQUEST_CODE_SEND_RED_PACKET);
            break;
        default:
            break;
        }
        //不覆盖已有的点击事件
        return false;
    }

发送红包消息到聊天页面

@Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        ...
        if(resultCode == Activity.RESULT_OK){
            switch (requestCode) {
            ...
            case REQUEST_CODE_SEND_RED_PACKET:
                if (data != null){
                    sendMessage(RedPacketUtils.createRPMessage(getActivity(), data, toChatUsername));
                }
                break;
            default:
                break;
            }
        }     
    }

领取红包并发送回执消息到聊天窗口

@Override
    public boolean onMessageBubbleClick(EMMessage message) {
        //消息框点击事件，demo这里不做覆盖，如需覆盖，return true
        if (message.getBooleanAttribute(RedPacketConstant.MESSAGE_ATTR_IS_RED_PACKET_MESSAGE, false)){
            RedPacketUtils.openRedPacket(getActivity(), chatType, message, toChatUsername, messageList);
            return true;
        }
        return false;
    }

ChatFragment中群红包领取回执的处理(聊天页面)

@Override
      public void onEvent(EMNotifierEvent event) {
          switch (event.getEvent()) {
              case EventNewCMDMessage:
                  EMMessage cmdMessage = (EMMessage) event.getData();
                  CmdMessageBody cmdMsgBody = (CmdMessageBody) cmdMessage.getBody();
                  final String action = cmdMsgBody.action;//获取自定义action
                  if (action.equals(RedPacketConstant.REFRESH_GROUP_RED_PACKET_ACTION)) {
                      RedPacketUtil.receiveRedPacketAckMessage(cmdMessage);
                      messageList.refresh();
                  }
                  break;
          }
          super.onEvent(event);
      }

MainActivity中群红包领取回执的处理(导航页面)

@Override
    public void onEvent(EMNotifierEvent event) {
        switch (event.getEvent()) {
        ...
        case EventNewCMDMessage:
            EMMessage cmdMessage = (EMMessage) event.getData();
            //获取消息body
            CmdMessageBody cmdMsgBody = (CmdMessageBody) cmdMessage.getBody();
            final String action = cmdMsgBody.action;//获取自定义action
            ...
            if (action.equals(RedPacketConstant.REFRESH_GROUP_RED_PACKET_ACTION)) {
                RedPacketUtil.receiveRedPacketAckMessage(cmdMessage);
            }
            refreshUIWithMessage();
            break;
        default:
            break;
        }
    }

5.群红包领取回执的全局处理

DemoHelper中

protected void registerEventListener() {
            eventListener = new EMEventListener() {
                private BroadcastReceiver broadCastReceiver = null;
                @Override
                public void onEvent(EMNotifierEvent event) {
                    switch (event.getEvent()) {
                        ...
                        case EventNewCMDMessage:
                            //获取消息body
                            CmdMessageBody cmdMsgBody = (CmdMessageBody) message.getBody();
                            final String action = cmdMsgBody.action;//获取自定义action
                            if(!easeUI.hasForegroundActivies()){
                                if (action.equals(RedPacketConstant.REFRESH_GROUP_RED_PACKET_ACTION)){
                                    RedPacketUtil.receiveRedPacketAckMessage(message);
                                    broadcastManager.sendBroadcast(new Intent(RedPacketConstant.REFRESH_GROUP_RED_PACKET_ACTION));
                                }
                            }
                            break;
                        ...
                    }
                }
            };
            EMChatManager.getInstance().registerEventListener(eventListener);
     }

MainActivity中

private void registerBroadcastReceiver() {
            broadcastManager = LocalBroadcastManager.getInstance(this);
            IntentFilter intentFilter = new IntentFilter();
            intentFilter.addAction(Constant.ACTION_CONTACT_CHANAGED);
            intentFilter.addAction(Constant.ACTION_GROUP_CHANAGED);
            intentFilter.addAction(RedPacketConstant.REFRESH_GROUP_RED_PACKET_ACTION);
            broadcastReceiver = new BroadcastReceiver() {
                
                @Override
                public void onReceive(Context context, Intent intent) {
                    ...
                    if (action.equals(RedPacketConstant.REFRESH_GROUP_RED_PACKET_ACTION)){
                         if (conversationListFragment != null){
                             conversationListFragment.refresh();
                         }
                    }
                }
            };
            broadcastManager.registerReceiver(broadcastReceiver, intentFilter);
        }

6.ConversationListFragment中对红包回执消息的处理

@Override
    protected void setUpView() {
       ...
       conversationListView.setConversationListHelper(new EaseConversationListHelper() {
                   @Override
                   public String onSetItemSecondaryText(EMMessage lastMessage) {
                       if (lastMessage.getBooleanAttribute(RedPacketConstant.MESSAGE_ATTR_IS_RED_PACKET_ACK_MESSAGE, false)) {
                           String sendNick = lastMessage.getStringAttribute(RedPacketConstant.EXTRA_RED_PACKET_SENDER_NAME, "");
                           String receiveNick = lastMessage.getStringAttribute(RedPacketConstant.EXTRA_RED_PACKET_RECEIVER_NAME, "");
                           String msg;
                           if (lastMessage.direct == EMMessage.Direct.RECEIVE) {
                               msg = String.format(getResources().getString(R.string.money_msg_someone_take_money), receiveNick);
                           } else {
                               if (sendNick.equals(receiveNick)) {
                                   msg = getResources().getString(R.string.money_msg_take_money);
                               } else {
                                   msg = String.format(getResources().getString(R.string.money_msg_take_someone_money), sendNick);
                               }
                           }
                           return msg;
                       }
                       return null;
                   }
       });
       super.setUpView();
    }

7.添加零钱页的入口

RedPacketUtils.startChangeActivity(getActivity());
