ParseQueryAdapter for RecyclerView

[marios-codes]

When parsequeryadapter will be compatible with recyclerview as of now it is only compatible with listview. Official android documentation suggests that we migrate to recyclerview and for some lollipop APIs to work we need recyclerview.

@msrowley thanks for opening this issue again. We don't have immediately plan for this feature but we will definitely do it in the future. Please keep an eye on this issue. I will update the status once we start to work on it.

Hello,

I found a gist by @ameron32 which adds support for RecyclerView. I am not sure if his approach is good but I am using it without any issue so far.

@ralphilius Thanks for the resource, we will take a look and try to add it to our repo as soon as possible. Since it works for you right now, I will close this issue. Feel free to re-open it if you have any questions.

@ralphilius Thank you very much for the info. I am trying to use this into my project, but I cannot understand where and if I should use the ViewHolder, onBindViewHolder(), and onCreateViewHolder methods that are required from recyclerview. Would it be easy for you to share some code to understand how I should use this gist as it is crucial for my app. Thank you again for your time!!

@msrowley If you notice that there are 3 possible Constructors. The 1st one is more adaptive. Let's say I am creating ParseGridAdapter. The code is:

public class ParseGridAdapter extends ParseRecyclerQueryAdapter<MyCustomModel, ParseGridAdapter.ViewHolder>{

public ParseGridAdapter(ParseQueryAdapter.QueryFactory<MyCustomModel> factory, boolean hasStableIds) {
    super(factory, hasStableIds);
    //Your other code here
}

Then you just need to do normally as with Recycler adapter.

factory can be obtained with below code or you just need to pass in your classname when declaring your adapter.

    ParseQueryAdapter.QueryFactory<YourCustomModel> factory = new ParseQueryAdapter.QueryFactory<YourCustomModel>() {
        @Override
        public ParseQuery<YourCustomModel> create() {
            ParseQuery<YourCustomModel> query = ParseWallpaper.getQuery();
           //Your other code here
            return query;
        }
    };

@ralphilius Thank you very much for your lightning fast reply. So to make things clear for me, I just have to use the first code snippet and then all the other stuff (like defining the row layout.xml and the view holder pattern ) are going to be configured on the recycler view methods? Sorry if I am a little confusing for you, but I am relatively new to this and I cannot easily make the connection between the classic parse query adapter and this gist. If you ever have some time and will, it would be very helpful for me if you could share an empty structure of this gist with all the methods I should use and when inside the code. Nonetheless, thank you for the above snippet, I will try to figure it out!!

[marios-codes]

@ralphilius Never mind!! I figured it out. My mistake was that I was trying to modify the original gist rather than extending it to my custom class. Thank you again for your time and the code snippets above!!

@wangmengyan95 I tried the above gist and it works really well for the basic adapter functionality but it misses crucial parsequeryadapter methods, that made development more easy and straightforward. So any news please from the official dev team on that matter??
