我尝试在回收器视图中添加任何新项目时自动发布数据
我已经尝试过单击项目，它可以正常工作，但是当任何项目添加到回收站视图中时，我想自动发布

这是我的Recycler视图适配器代码
我想在数据添加到回收站视图时自动发布数据
答案 0 :(得分：0)
在适配器中更新歌曲名称时，只需匹配差异并发布列表中新项目的数据
答案 1 :(得分：0)
您需要在适配器中制作这样的方法。
void addItem(String songName){
datas.add(songName); // Add new Item into the data list in your Adapter.
notifyDataSetChanged();
}
然后在这样的活动中调用它：
adapter.addItem(name);
然后，它将自动更改。
答案 2 :(得分：0)
您需要分离关注点。
notifyDatasetChanged()。理想情况下，您的应用应在此进行网络通话（或在将商品添加到列表之前）。bind方法是不可靠的，因为当用户滚动列表时会多次调用它。
