There is a delay in updating the list of Recycler views. When items in the list are small, they are processed quickly, but when items are large, delays occur. The model of all items is the same, but it does not seem to be possible to use methods like NotifyItemChanged because it expresses different information and number.
@Override
public void onFolderCoverImgClick(int position) {
setVideoTopBarByFolderData(position);
AppVideoData.FolderData folderData = videoLayoutFolderList.get(position);
String folderId = folderData.getFolderId();
videoByFolderList.clear();
for (int i = 0; i < videoLayoutList.size(); i++) {
if (folderId.equals(videoLayoutList.get(i).getFolderId())) {
videoByFolderList.add(videoLayoutList.get(i));
}
}
String path = getFilesDir() + File.separator + "vid";
for (int i = 0; i < videoByFolderList.size(); i++) {
if (new File(path + File.separator + videoByFolderList.get(i).getId() + ".mp4").exists()) {
videoByFolderList.get(i).setVideoType("Download");
} else {
videoByFolderList.get(i).setVideoType("vimeo");
}
if(videoIdF.equals(videoByFolderList.get(i).getId())) {
videoPosF = i;
}
}
videoPortraitAdapter.updateList(videoByFolderList);
videoPortraitAdapter.checkSelectedVideoWhenFolder(videoPosF, videoIdF);
}
If I click on a specific view, it will be called back to the above method, and clear the list that was originally in the recycler view and update the new list to be shown. The rest of the code is responsible for additional processing. I tried to calculate the time using the 'System.currentTimeMillis' method, but it does not seem to cause delays in additional code.

This is a recycler view adapter class. In the onBindViewHolder method of the adapter, even if I calculate the time using System.currentTimeMillis, I can not see anything that delay could happen. It took 0.005 to 0.01 seconds. There is a place of doubt, but I do not know exactly where to check it. It looks like there is a difference of about 0.6 seconds between 'onFolderCoverImgClick' and onBindViewHolder.
videoPortraitAdapter is an instance of VideoItemAdapter. If you know anyone, I would appreciate it if you could.
