问题 I'm getting this error when trying to pull data from Parse.com (backend database). The error is saying that the put function in the Businesses class is not null. I'm not sure what that means, because isn't it suppose to not be null? I want to display the name of businesses so the name would have to be there in order to do this right? Or is it saying that the value can't be null in others words? FATAL EXCEPTION: main Process: zafir.com.app, PID: 13295 java.lang.IllegalArgumentException: value

问题 I need an Activity with an expandable RecyclerView like the one in this picture: So I am using this third party library project . That part works. The problem arose when I did what I am describing in the next two paragraphs: My next requirement is that I want different child-rows for different parent-rows. I am reproducing (if that's the right word) this example to create multiple child-viewholders. Description of Example: The idea is basically to have the different Child-viewholders

问题 For the question I have prepared a simple and working example at Github: My example app downloads a JSON array containing top 30 players in a game using okhttp and stores them into SQLite Room. In the fragment I observe the corresponding LiveData<List<TopEntity>> object and update the FastAdapter instance: public class TopFragment extends Fragment { private final ItemAdapter<TopItem> mItemAdapter = new ItemAdapter<>(); private final FastAdapter<TopItem> mFastAdapter = FastAdapter.with

问题 I have a Recyclerview, im animating a view inside individual list item, but when I scroll the recyclerview the animation is stopping. Its because recyclerview removes the items form its view so when we scroll back it fetches it back! But now i want that animation to keep going as I would stop it only when i get data from server! All I want is the animation that I start in the individual items inside the recylerview shouldn't stop even if the recyclerview is scrolled and the view is out of

问题 I want change my RecyclerView item background with alternating color. Here is the method in Adapter. public class NewsAdapter extends RecyclerView.Adapter<NewsAdapter.ViewHolder> { private List<NewsModel> mNewsList; class ViewHolder extends RecyclerView.ViewHolder { TextView newsNameText; TextView newsDataText; View listView; public ViewHolder(View newsView) { super(newsView); newsNameText = (TextView) newsView.findViewById(R.id.news_Name); newsDataText = (TextView) newsView.findViewById(R.id

问题 I have created a RecyclerView with a very similar design to the one mentioned here and even used the excellent self-supplied solution in my implementation.

To resolve this I followed the

问题 I'm using RecyclerView with CardView to display a list of Cards. Every card has 2 linearLayout (1 for the header, and 1 for the expand, the second one became visible only when the card is pressed). When I modify the priority of a card, the card is moved in a new position of the list (I change it's position in the "array" of item, and then call adapter.notifyItemMoved(oldPosition,newPosition) ) and it works, I also called RecyclerView.scrollToPosition(newPosition) to show the new position in

问题 It uses retrofit 2.0 to fetch the data from the webservice and bind it to the card view. When I click on the card view having image and textviews, on click is not triggering, rather a strange behaviour is at the very corner edges of the card view onclick is triggering.
