實現聊天，首先要知道聊天雙方的CID，這裡可以獲取到，將其存起來。
這裡用模擬器測試一下，準備倆臺模擬器，分別獲得其CID；準備好聊天介面；注備好聊天介面，就可以測試了。

一、web後臺Contraller

package com.smxy.office.controller;

@Controller
public class AppPush {

    //定義常量, appId、appKey、masterSecret 採用本文件 "第二步 獲取訪問憑證 "中獲得的應用配置
    private static String appId = "";
    private static String appKey = "";
    private static String masterSecret = "";
    private static String url = "http://sdk.open.api.igexin.com/apiex.htm";
    
    //這裡先寫死
    private static String CID = "e9ef48ef0ef7155580995aa3b8410d93";
    
    //聊天介面-----ChatUser(cid,chatContentString)
	@RequestMapping("/pushMessage")
    public  void  pushMessage( @RequestBody ChatUser chatUser) throws Exception{
		String cid = chatUser.getCid();
		String msg = chatUser.getMsg();
        IIGtPush push = new IGtPush(url, appKey, masterSecret);
        IBatch batch = push.getBatch();
        System.out.println("CID="+cid+",msg="+msg);
        try {
            //構建客戶a的透傳訊息a
            constructClientTransMsg(cid,msg,batch);
        } catch (Exception e) {
            e.printStackTrace();
        }
        batch.submit();
    }

    private static void constructClientTransMsg(String cid, String msg ,IBatch batch) throws Exception {

        SingleMessage message = new SingleMessage();
        TransmissionTemplate template = new TransmissionTemplate();
        template.setAppId(appId);
        template.setAppkey(appKey);
        template.setTransmissionContent(msg);
        template.setTransmissionType(0); // 這個Type為int型，填寫1則自動啟動app

        message.setData(template);
        message.setOffline(true);
        message.setOfflineExpireTime(1 * 1000);

        // 設定推送目標，填入appid和clientId
        Target target = new Target();
        target.setAppId(appId);
        target.setClientId(cid);
        batch.add(message, target);
    }

}
 

二、App聊天介面

public class MessageFragment extends BaseFragement {
    ChatUser chatUser;
    public static String URL = "http://lj1757620885.6655.la:54746/office/pushMessage?cid=";
    private SharedPreferencesHelper sharedPreferencesHelper;
    private String CID,sendMesageContent;//好友的CID
    private List<Message> msgList = new ArrayList<>();
    @BindView(R.id.message_text) EditText inputText;
    @BindView(R.id.msg_recycler_view) RecyclerView msgRecyclerView;
    private MsgAdapter msgAdapter;
    private DemoIntentService msgService;

    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.memo_lists, null);
        ButterKnife.bind(this,view);
        Intent intent = new Intent(getActivity(), DemoIntentService.class);
        getActivity().bindService(intent, mServiceConnection, Context.BIND_AUTO_CREATE);

        initMsgs();//初始化聊天介面
        inputText = view.findViewById(R.id.message_text);//聊天輸入框
        msgRecyclerView = view.findViewById(R.id.msg_recycler_view);
        LinearLayoutManager layoutManager = new LinearLayoutManager(getActivity());
        msgRecyclerView.setLayoutManager(layoutManager);
        msgAdapter = new MsgAdapter(msgList);
        msgRecyclerView.setAdapter(msgAdapter);

        return view;
    }

    private void initMsgs() {
        //chatUser = new ChatUser();
        sharedPreferencesHelper = new SharedPreferencesHelper(getContext(),"push_CID");
        CID = (String) sharedPreferencesHelper.getSharedPreference("cid",null);
        MyLog.e("CID==="+CID);
        Message msg1 = new Message("物一群的邀請碼是多少", Message.TYPE_RECEIVED);
        msgList.add(msg1);
        Message msg2 = new Message("0X897888V", Message.TYPE_SENT);
        msgList.add(msg2);
        Message msg3 = new Message("謝謝你", Message.TYPE_RECEIVED);
        msgList.add(msg3);

    }
//傳送按鈕點選事件，將聊天內容傳給好友
    @OnClick(R.id.message_send)
    public void sedMessage(){
        sendMesageContent = inputText.getText().toString();
        chatUser = new ChatUser();
        chatUser.setCid("fb61f569efd33cf3eb536eb945537acb");
        chatUser.setMsg(sendMesageContent);
        if (!"".equals(sendMesageContent)) {
            Message msg = new Message(sendMesageContent, Message.TYPE_SENT);
            msgList.add(msg);
            //當有新訊息時，呼叫介面卡notifyItemInserted通知列表有新的資料插入，重新整理RecyclerView
            msgAdapter.notifyItemInserted(msgList.size() - 1);
            //將RecyclerView定位到最後一行，保證可以看到最新訊息
            msgRecyclerView.scrollToPosition(msgList.size() - 1);
            inputText.setText("");
            Gson gson = new Gson();
            String json = gson.toJson(chatUser);
            HttpUtil.getCall("/pushMessage",json).enqueue(new Callback() {
                @Override
                public void onFailure(Call call, IOException e) {
                }
                @Override
                public void onResponse(Call call, Response response) throws IOException {
                }
            });

        }
    }

    ServiceConnection mServiceConnection = new ServiceConnection() {
        @Override
        public void onServiceConnected(ComponentName componentName, IBinder iBinder) {
            msgService = ((DemoIntentService.MyGeTui) iBinder).get();

            msgService.setOnProgressListener(new DemoIntentService.OnProgressListener() {
                @Override
                public void onProgress(String  progress) {
                 //   mProgressBar.setProgress(progress);

                    android.os.Message message = android.os.Message.obtain();
                    message.obj = progress;
                    mHandler.sendMessage(message);
                }
            });
        }

        @Override
        public void onServiceDisconnected(ComponentName componentName) {

        }
    };

    private Handler mHandler = new Handler(new Handler.Callback() {
        @Override
        public boolean handleMessage(android.os.Message message) {
            Message msg = new Message((String) message.obj, Message.TYPE_RECEIVED);//接收者
            msgList.add(msg);
            //當有新訊息時，呼叫介面卡notifyItemInserted通知列表有新的資料插入，重新整理RecyclerView
            msgAdapter.notifyItemInserted(msgList.size() - 1);
            //將RecyclerView定位到最後一行，保證可以看到最新訊息
            msgRecyclerView.scrollToPosition(msgList.size() - 1);
            return true;
        }
    });
}
