TUIKit implements the sending and display for basic message types such as text, image, voice, video, and file messages by default. If these message types do not meet your requirements, you can add custom message types.
Message Type | Renderings |
---|---|
Text message | ![]() |
Image message | ![]() |
Voice message | ![]() |
Video message | ![]() |
File message | ![]() |
You can receive a custom message via the onRecvNewMessage
method in ChatPresenter.java, and the received custom message will be displayed in MessageViewHolder
mode in the message list. The data required for MessageViewHolder
drawing is called MessageBean
. The following introduces how to display a custom message.
CustomLinkMessageBean.java
file in TUIChat/tuichat/src/main/java/com/tencent/qcloud/tuikit/tuichat/bean/message/
. Inherit data from TUIMessageBean
to the CustomLinkMessageBean
class to store the text to display and the link to redirect.public class CustomLinkMessageBean extends TUIMessageBean {
private String text;
private String link;
public String getText() {
return text;
}
public String getLink() {
return link;
}
}
onProcessMessage(message)
method of CustomLinkMessageBean
to implement custom message parsing. To achieve this, add the following code to CustomLinkMessageBean.java
:@Override
public void onProcessMessage(V2TIMMessage v2TIMMessage) {
// Custom message view implementation. Here we configure to display only the text information and implement link redirection.
text = TUIChatService.getAppContext().getString(R.string.no_support_msg);
link = "";
String data = new String(v2TIMMessage.getCustomElem().getData());
try {
HashMap map = new Gson().fromJson(data, HashMap.class);
if (map != null) {
text = (String) map.get("text");
link = (String) map.get("link");
}
} catch (JsonSyntaxException e) {
}
setExtra(text);
}
onGetDisplayString()
method of CustomLinkMessageBean
to generate the text summary in the conversation list.CustomLinkMessageBean.java
:@Override
public String onGetDisplayString() {
return text;
}
CustomLinkMessageHolder.java
file in TUIChat/tuichat/src/main/java/com/tencent/qcloud/tuikit/tuichat/ui/view/message/viewholder/
. Inherit data from MessageContentHolder
to CustomLinkMessageHolder
to implement the bubble style layout and click event of the custom message.public class CustomLinkMessageHolder extends MessageContentHolder {
public CustomLinkMessageHolder(View itemView) {
super(itemView);
}
}
getVariableLayout
method of CustomLinkMessageHolder
and go back to the layout of the custom message.@Override
public int getVariableLayout() {
return R.layout.test_custom_message_layout1;
}
layoutVariableViews
method of CustomLinkMessageHolder
to render the custom message to the layout and add the custom message click event.@Override
public void layoutVariableViews(TUIMessageBean msg, int position) {
// Custom message view implementation. Here we configure to display only the text information and implement link redirection.
TextView textView = itemView.findViewById(R.id.test_custom_message_tv);
String text = "";
String link = "";
if (msg instanceof CustomLinkMessageBean) {
text = ((CustomLinkMessageBean) msg).getText();
link = ((CustomLinkMessageBean) msg).getLink();
}
textView.setText(text);
msgContentFrame.setClickable(true);
String finalLink = link;
msgContentFrame.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent();
intent.setAction("android.intent.action.VIEW");
Uri content_url = Uri.parse(finalLink);
intent.setData(content_url);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
TUIChatService.getAppContext().startActivity(intent);
}
});
msgContentFrame.setOnLongClickListener(new View.OnLongClickListener() {
@Override
public boolean onLongClick(View v) {
if (onItemLongClickListener != null) {
onItemLongClickListener.onMessageLongClick(v, position, msg);
}
return false;
}
});
}
In this mode, the addCustomMessageType
method is called to register the custom message.
private void initMessageType() {
addCustomMessageType("text_link", // Unique ID of the custom message (Duplicated IDs are not allowed.)
CustomLinkMessageBean.class, // MessageBean type of the message, which is the MessageBean class created in step 1
CustomLinkMessageHolder.class); // MessageViewHolder type of the message, which is the MessageViewHolder class created in step 2
}
customizeChatLayout
method in ChatLayoutSetting.java to add the custom message sending button:InputMoreActionUnit unit = new InputMoreActionUnit() {};
unit.setIconResId(R.drawable.custom);
unit.setTitleId(R.string.test_custom_action);
unit.setActionId(CustomHelloMessage.CUSTOM_HELLO_ACTION_ID);
unit.setPriority(10);
inputView.addAction(unit);
businessID
field in JSON to uniquely identify the message type.unit.setOnClickListener(unit.new OnActionClickListener() {
@Override
public void onClick() {
Gson gson = new Gson();
CustomHelloMessage customHelloMessage = new CustomHelloMessage();
customHelloMessage.businessID = "text_link";
customHelloMessage.text = "Welcome to Tencent Cloud IM group";
customHelloMessage.link = "https://intl.cloud.tencent.com/document/product/269/3794?from_cn_redirect=1";
String data = gson.toJson(customHelloMessage);
TUIMessageBean info = ChatMessageBuilder.buildCustomMessage(data, customHelloMessage.text, customHelloMessage.text.getBytes());
layout.sendMessage(info, false);
}
});
