优悦家装发送消息流程

发送文本消息

点击按钮 —> 构造文本消息对象—> 设置@的人员 —> base64编码—> 保存消息到本地数据库—> 发送消息—>发送完毕后修改消息发送状态
点击发送按钮后，页面(ChatFragment.java)响应发送事件

// 发送按钮点击事件
ekBar.getBtnSend().setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        String text = ekBar.getEtChat().getText().toString();
        if (!TextUtils.isEmpty(text)) {
            onSendBtnClick(text);   //发送
            ekBar.getEtChat().setText("");
        }
    }
});

/**
 * 当点击了发送按钮，发送文本消息
 * @param sendText
 */
private void onSendBtnClick(String sendText) {
    if (TextUtils.isEmpty(sendText) || TextUtils.isEmpty(sendText.trim())) {
        return;
    }
    long groupId = mGroupBean.getGroupId();
    long userId = AuthManager.getUid(getContext());
    String nickname = AuthManager.getName(getContext());
    String avatar = AuthManager.getAvatar(getContext());
    QXGroupTextMessage qxMessage = QXMessageCreator.createQXGroupTextMessage(groupId, userId, nickname, avatar, sendText, mGroupBean.getGroupType());
    //设置@了哪些人
    if(atUserInfoList != null){
        List<String> asList = new ArrayList<>();
        for(AtUserInfo userInfo : atUserInfoList){
            asList.add(userInfo.getUserId());
        }
        qxMessage.setAtList(asList);
    }
    sendQXGroupMessage(qxMessage);//发送消息
    ChatBean chatBean = new ChatBean(qxMessage);
    chatBean.setSendStatus(ChatBean.SEND_STATUS_PROCESS);
    dataList.add(chatBean);
    //Utils.hideSoftInput(mActivity);
}

private void sendQXGroupMessage(QXGroupMessage message) {
try {
    QXIMClient.sendMessage(message);
    //给首页->企信界面发送事件，让其更新其界面
    MessageSendEvent messageSendEvent = new MessageSendEvent(MessageSendEvent.SEND_MESSAGE_PROCESS, projectId, message.toDisplayMessage());
    RxBus.get().post(messageSendEvent);
} catch (Exception e) {
    e.printStackTrace();
    if (BuildConfig.LOG_DEBUG) {
        Log.w(TAG, "call sendMessage but send fail : " + e);
    }
}
}

最后会调用如下代码发送消息，如下所示，先设置一个唯一的ID（clientMessageId），以便区分消息。将消息加入到发送消息的集合(processGroupMessageList)中，当消息发送成功\失败后，再从集合中移除。
如果是文本消息，需要先进行base64编码。

private void sendMessage(QXGroupMessage qxmsg, boolean isFirstSend){
    Log.v("sendMessage : "+qxmsg);
    if(qxmsg == null){
        return;
    }
    //如果clientMessageId等于空,代表是不是重发消息,是第一次发送消息
    if(qxmsg.getClientMessageId() == null || "".equals(qxmsg.getClientMessageId())){
        String uuid = UUID.randomUUID().toString();
        qxmsg.setClientMessageId(uuid);
        sendQXMessageToByStoreHandler(qxmsg, WHAT_MESSAGE_SEND);
    }else{
        qxmsg.setSendTime(System.currentTimeMillis());
    }
    if(isFirstSend){
        if(!processGroupMessageList.contains(qxmsg)){
            processGroupMessageList.add(qxmsg);
        }
    }
    //如果需要base64编码
    if(isNeedBase64Encode){
        if(qxmsg instanceof QXGroupTextMessage){//只有文本消息才需要base64编码
            QXGroupTextMessage groupTextMessage = (QXGroupTextMessage)qxmsg;
            String data = groupTextMessage.getData();
            String base64 = Base64.encodeToString(data.getBytes(), Base64.NO_WRAP);
            QXGroupTextMessage message= QXMessageCreator.createQXGroupTextMessage(groupTextMessage.getGroupId(), groupTextMessage.getUserId(), groupTextMessage.getName(), null, base64, groupTextMessage.getGroupType());
            message.setId(groupTextMessage.getId());
            message.setClientMessageId(groupTextMessage.getClientMessageId());
            message.setAtList(groupTextMessage.getAtList());
            sendMessage(message.toTransactString());
        }else{
            sendMessage(qxmsg.toTransactString());
        }
    }else{
        sendMessage(qxmsg.toTransactString());
    }
}

发送图片消息

发送图片有两种方式，一种是从相册选择图片，另一种是拍照。

选择图片 —> 压缩图片—> 上传图片—> 构造图片消息对象 —>保存消息到本地数据库—> 发送消息—>发送完毕后修改消息发送状态

发送图片的逻辑是先将图片压缩，然后上传图片到服务器，然后发送图片消息，代码如下：

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    Log.v("requestCode " + requestCode + ", resultCode = " + resultCode);
    if (resultCode == RESULT_OK) {
        if (requestCode == CAMERA_REQUEST) {
            if (mCameraFile != null && mCameraFile.exists()) {
                //拍照后回调
                cameraPictureActivityResult(mCameraFile.getPath());
            }
        } else if (requestCode == IMAGE_REQUEST) {
            List<String> paths = data.getStringArrayListExtra(MultiImageSelectorActivity.EXTRA_RESULT);
            if (paths != null && paths.size() > 0) {
                //从相处选择后回调
                imagesSelectActivityResult(paths);
            }
        } else if (requestCode == LOCATION_REQUEST) {
            if (data != null) {
                double lat = data.getDoubleExtra("latitude", 0.0);
                double lot = data.getDoubleExtra("longitude", 0.0);
                String address = data.getStringExtra("address");
                String imagePath = data.getStringExtra("imagepath");
                scrollToBottom();
                locationActivityResult(lat, lot, address, imagePath);
                Log.v("位置:" + address + ":" + lat + ":" + lot + ":" + imagePath);
            }
        } else if (requestCode == FilePickerConst.REQUEST_CODE_DOC) {
            if (data != null) {
                ArrayList<String> documentPaths = data.getStringArrayListExtra(FilePickerConst.KEY_SELECTED_DOCS);
                documentActivityResult(documentPaths);
            }
        }
    }
}

        uploadSendImageMessage(paths);
    }

    private void uploadSendImageMessage(List<String> imagePaths) {

            message.setName(AuthManager.getName(mContext));
            message.setAvatar(AuthManager.getAvatar(mContext));
            message.setLocalPath(string);
            BitmapFactory.decodeFile(string, options);
            message.setWidth(options.outWidth);
            message.setHeight(options.outHeight);
            ChatBean chatBean = new ChatBean(message);
