Feature customization

Customize message style

The barrage display component TUIBarrageDisplayView provides setAdapter and TUIBarrageDisplayAdapter for customizing the pop-up message Item style. If you need the Self Definition message view, please refer to the following path for changes.
// File Location: tuilivekit/src/main/java/com/trtc/uikit/livekit/common/uicomponent/barrage/view/adapter/TUIBarrageDisplayAdapter.java
public interface TUIBarrageDisplayAdapter {
    RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType);

    void onBindViewHolder(RecyclerView.ViewHolder holder, TUIBarrage barrage);

    int getItemViewType(int position, TUIBarrage barrage);
}
// File Location: tuilivekit/src/main/java/com/trtc/uikit/livekit/common/uicomponent/gift/view/GiftBarrageAdapter.java
public class GiftBarrageAdapter implements TUIBarrageDisplayAdapter {
    private final Context       mContext;

    public GiftBarrageAdapter(Context context) {
        mContext = context;
    }

    @Override
    public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        if (viewType == GIFT_VIEW_TYPE_1) {
            // Handling of custom style 1
            LinearLayout ll = new LinearLayout(mContext);
            ll.addView(new TextView(mContext));
            return new GiftViewHolder(ll);
        }
        return null;
    }

    @Override
    public void onBindViewHolder(RecyclerView.ViewHolder holder, TUIBarrage barrage) {
        if (holder instanceof GiftViewHolder) {
            GiftViewHolder viewHolder = (GiftViewHolder) holder;
            viewHolder.bind(barrage);
        }
    }

    @Override
    public int getItemViewType(int position, TUIBarrage barrage) {
        if (...) { // If the current barrage requires a custom Item style, return the corresponding style type.
            return GIFT_VIEW_TYPE_1;
        }
        return 0; // 0 indicates that the default style is used
    }

    private static class GiftViewHolder extends RecyclerView.ViewHolder {

        public GiftViewHolder(View itemView) {
            super(itemView);
            // ...
        }

        public void bind(TUIBarrage barrage) {
            // ...
        }
    }
}
            
// set custom Adapter
barrageDisplayView.setAdapter(new GiftBarrageAdapter(mContext));
TUIBarrage is defined as follows:
// File Location:
// tuilivekit/src/main/java/com/trtc/uikit/livekit/common/uicomponent/barrage/model/TUIBarrage.java
// tuilivekit/src/main/java/com/trtc/uikit/livekit/common/uicomponent/barrage/model/TUIBarrageUser.java
public class TUIBarrage {
    public final TUIBarrageUser    user = new TUIBarrageUser(); //Sender
    public String                  content;                     //Sent content
    public HashMap<String, Object> extInfo = new HashMap<>();   //Expanded informati
}

public class TUIBarrageUser {
    public String userId;
    public String userName;
    public String avatarUrl;
    public String level;
}
Note：
Supports multiple custom styles (specified by multiple return values through getItemViewType ), 0 represents the default style.

Insert Custom Message

The barrage display component TUIBarrageDisplayView provides the external interface method insertBarrages for inserting custom messages (in batches). Custom messages are usually used in combination with custom styles to achieve different display effects.
// Example: Insert a gift message in the barrage area.
TUIBarrage barrage = new TUIBarrage();
barrage.content = "gift";
barrage.user.userId = sender.userId;
barrage.user.userName = sender.userName;
barrage.user.avatarUrl = sender.avatarUrl;
barrage.user.level = sender.level;
barrage.extInfo.put(Constants.GIFT_VIEW_TYPE, GIFT_VIEW_TYPE_1);
barrage.extInfo.put(GIFT_NAME, barrage.giftName);
barrage.extInfo.put(GIFT_COUNT, giftCount);
barrage.extInfo.put(GIFT_ICON_URL, barrage.imageUrl);
barrage.extInfo.put(GIFT_RECEIVER_USERNAME, receiver.userName);
barrageDisplayView.insertBarrages(barrage);
Note：
The extInfo of TUIBarrage is a Map, used for storing custom data.

Key code

Integration

The barrage component mainly provides two Objects：
TUIBarrageButton：Clicking it can bring up the input interface.
TUIBarrageDisplayView：Used for displaying barrage messages.
In scenarios where barrage messages need to be sent, create a TUIBarrageButton , which can bring up the input interface when clicked:
// File Location: tuilivekit/src/main/java/com/trtc/uikit/livekit/common/uicomponent/barrage/TUIBarrageButton.java
TUIBarrageButton barrageButton = new TUIBarrageButton(mContext, roomId);
mBarrageButtonContainer.addView(barrageButton);
In scenarios where barrage messages need to be displayed, use TUIBarrageDisplayView to show the barrage messages:
// File Location: tuilivekit/src/main/java/com/trtc/uikit/livekit/common/uicomponent/barrage/TUIBarrageDisplayView.java
TUIBarrageDisplayView barrageDisplayView = new TUIBarrageDisplayView(mContext, roomId);
mLayoutBarrageContainer.addView(barrageDisplayView);
