名片分享.jpg
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;
