remove list parameter onevent method. instead use list put event. either require make field public in event or add getter list.
something this:
public class myevent { public string fragmenttag ; private list<datamodel> infomodels = new arraylist(); public myevent (string tag,list<datamodel> models){ this.fragmenttag = tag; this.infomodels = models; } public list<datamodel> getinfomodels() { return infomodels; } } @subscribe public void onevent(myevent event) { list<datamodel> datamodels = event.getinfomodels(); if (datamodels.size() > 0) { datamodels.remove(datamodels.size() - 1); madapter.notifyitemremoved(datamodels.size()); //madapter.setloaded(); } if (event.fragmenttag.equals("forfragment2")) { madapter.add(maininfomodels); madapter.notifydatasetchanged(); } }
