    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);
