您的问题归结为对
VideoYTAdapterHomevideoList视频列表本身进行排序，而是制作一份副本并对该副本进行排序：
public
AdapterHome(Context context, List<VideoYT> videoList) {
this.context = context;
this.videoList = new ArrayList<>(videoList);
Collections.sort(this.videoList, myComparator);
}
公共
AdapterHome（上下文，列表视频列表）{
this.context=上下文；
this.videoList=新的数组列表（videoList）；
Collections.sort（this.videoList，myComparator）；
}
您能解释一下在适配器中的最后一部分（collection.sort）添加到哪里吗？已经说过：在类的构造函数中AdapterHome
。请看我上面编辑的答案。谢谢。但现在它没有显示任何内容。空白屏幕没有您选择的两个选项中的任何一个？第二个。让我也试试第一个
public
AdapterHome(Context context, List<VideoYT> videoList) {
this.context = context;
Collections.sort(videoList, myComparator);
this.videoList = videoList;
}
public
AdapterHome(Context context, List<VideoYT> videoList) {
this.context = context;
this.videoList = new ArrayList<>(videoList);
Collections.sort(this.videoList, myComparator);
}
