我想告訴用戶文檔的渠道

Answer 1

加「通道」 peroperty在文件類別，然後：

 com.couchbase.lite.View channelView = _database.getView("channels"); 
     channelView.setMap(new Mapper() { 
      @Override 
      public void map(Map<String, Object> document, Emitter emitter) { 
       ArrayList<String> channel = (List) document.get("channel"); 
       String name = (String) document.get("ch_name"); 
       emitter.emit(channel, name); 
      } 
     }, "2"); 


private void startLiveQuery(com.couchbase.lite.View view) throws Exception { 
    if (_liveQuery == null) { 
     _liveQuery = view.createQuery().toLiveQuery(); 
     _liveQuery.addChangeListener(new LiveQuery.ChangeListener() { 
      public void changed(final LiveQuery.ChangeEvent event) { 
       new Thread(new Runnable() { 
        @Override 
        public void run() { 
         for (final Iterator<QueryRow> it = event.getRows(); it.hasNext();) { 
          QueryRow query = it.next(); 
          _channel = (String) query.getKey(); 
          _name = (String) query.getValue(); 
         } 
        } 
       }).start(); 
      } 
     }); 
     _liveQuery.start(); 
    } 
}
