环信自定义消息类型——名片

近来的需求需要对环信进行定制化,实现如图所示的名片分享功能。
环信聊天中的每一种消息类型都由一种对应的ChatRow来控制,相当于adapter里的Holder。

自定义GroupCardChatRow继承EaseChatRow,在 onBubbleClick()中重写消息的点击事件。

public class GroupCardChatRow extends EaseChatRow {

    private TextView contentView;
    private TextView tvGroupName;
    private ImageView imgGroup;
    private TextView tvIntroduce;
    private TextView tvNember;
    private String gid;

    public GroupCardChatRow(Context context, EMMessage message, int position, BaseAdapter adapter) {
        super(context, message, position, adapter);
    }

   //接收和发送名片消息的布局
    @Override
    protected void onInflateView() {
        inflater.inflate(message.direct() == EMMessage.Direct.RECEIVE ?
                R.layout.ease_row_received_group_card : R.layout.ease_row_sent_group_card, this);
    }

    @Override
    protected void onFindViewById() {
        contentView = (TextView) findViewById(R.id.tv_chatcontent);
        tvGroupName = (TextView) findViewById(R.id.tv_group_name);
        imgGroup = (ImageView) findViewById(R.id.img_group);
        tvIntroduce = (TextView) findViewById(tv_introduce);
        tvNember = (TextView) findViewById(R.id.tv_number);
    }

    @Override
    public void onSetUpView() {

        try {
            Map<String, String> map = new HashMap<>();
            map = new Gson().fromJson(message.getStringAttribute(EaseConstant.EXTRA_GROUP_CARD), Map.class);
            String name = map.get("name");
            String description = map.get("description");
            String pic = map.get("pic");
            String memberCount = map.get("member_count");
            gid = map.get("gid");
            tvGroupName.setText(name);
            ImageUtil.loadImageWithView(context, pic, imgGroup);
            tvIntroduce.setText(description);
            tvNember.setText("群成员人数:" + memberCount + "人");

        } catch (HyphenateException e) {
            e.printStackTrace();
        }
        handleTextMessage();
    }

    protected void handleTextMessage() {
        if (message.direct() == EMMessage.Direct.SEND) {
            setMessageSendCallback();
            switch (message.status()) {
                case CREATE:
                    progressBar.setVisibility(View.GONE);
                    statusView.setVisibility(View.VISIBLE);
                    break;
                case SUCCESS:
                    progressBar.setVisibility(View.GONE);
                    statusView.setVisibility(View.GONE);
                    break;
                case FAIL:
                    progressBar.setVisibility(View.GONE);
                    statusView.setVisibility(View.VISIBLE);
                    break;
                case INPROGRESS:
                    progressBar.setVisibility(View.VISIBLE);
                    statusView.setVisibility(View.GONE);
                    break;
                default:
                    break;
            }
        } else {
            if (!message.isAcked() && message.getChatType() == ChatType.Chat) {
                try {
                    EMClient.getInstance().chatManager().ackMessageRead(message.getFrom(), message.getMsgId());
                } catch (HyphenateException e) {
                    e.printStackTrace();
                }
            }
        }
    }

    @Override
    protected void onUpdateView() {
        adapter.notifyDataSetChanged();
    }

    @Override
    protected void onBubbleClick() {
        // TODO Auto-generated method stub

        Intent intent = new Intent(context, GroupCardActivity.class);
        intent.putExtra("gid", gid);
        context.startActivity(intent);


    }
}

环信中消息类型包括txt、音频、位置、文件、图片、视频类型,群名片也属于txt类型,我们通过message的拓展字段来区分消息类型是否为名片。

发送群名片消息的时候给message添加群名片拓展字段,发送正常txt消息时不添加拓展字段,在adapter中根据拓展字段是否为空来判断消息类型


protected void sendMessage(UserPageBean userPageBean) {

        EMMessage message = EMMessage.createTxtSendMessage("群邀请", userPageBean.getIm_namelogin());

        message.setAttribute(EaseConstant.EXTRA_GROUP_CARD, groupMessage);
        EMClient.getInstance().chatManager().sendMessage(message);

    }

在EaseMessageAdapter中新添加两种消息类型
MESSAGE_TYPE_SENT_GROUP_CARD 、 MESSAGE_TYPE_RECV_GROUP_CARD

修改 getItemViewType和createChatRow方法,在其中添加这两种消息类型

public class EaseMessageAdapter extends BaseAdapter {

    private final static String TAG = "msg";

    private Context context;
    private static final int HANDLER_MESSAGE_REFRESH_LIST = 0;
    private static final int HANDLER_MESSAGE_SELECT_LAST = 1;
    private static final int HANDLER_MESSAGE_SEEK_TO = 2;

    private static final int MESSAGE_TYPE_RECV_TXT = 0;
    private static final int MESSAGE_TYPE_SENT_TXT = 1;
    private static final int MESSAGE_TYPE_SENT_IMAGE = 2;
    private static final int MESSAGE_TYPE_SENT_LOCATION = 3;
    private static final int MESSAGE_TYPE_RECV_LOCATION = 4;
    private static final int MESSAGE_TYPE_RECV_IMAGE = 5;
    private static final int MESSAGE_TYPE_SENT_VOICE = 6;
    private static final int MESSAGE_TYPE_RECV_VOICE = 7;
    private static final int MESSAGE_TYPE_SENT_VIDEO = 8;
    private static final int MESSAGE_TYPE_RECV_VIDEO = 9;
    private static final int MESSAGE_TYPE_SENT_FILE = 10;
    private static final int MESSAGE_TYPE_RECV_FILE = 11;
    private static final int MESSAGE_TYPE_SENT_EXPRESSION = 12;
    private static final int MESSAGE_TYPE_RECV_EXPRESSION = 13;
    private static final int MESSAGE_TYPE_SENT_GROUP_CARD = 14;
    private static final int MESSAGE_TYPE_RECV_GROUP_CARD = 15;
