Firebaserecycleradapter() Cannot Be Applied to Firebaserecycleradapter

firebaserecycleradapter() cannot be applied to FirebaseRecyclerAdapter

The latest version (3.x) of FirebaseUI implements a different method of initializing a FirebaseRecyclerAdapter than previous versions. From the using the FirebaseRecyclerAdapter documentation:

First, configure the adapter by building FirebaseRecyclerOptions. In
this case we will continue with our chat example:

 FirebaseRecyclerOptions<Chat> options =
                new FirebaseRecyclerOptions.Builder<Chat>()
                        .setQuery(query, Chat.class)
                        .build();

Next create the FirebaseRecyclerAdapter object. You should already
have a ViewHolder subclass for displaying each item.

So, for your example, you'll need to do something similar to:

FirebaseRecyclerOptions<image_details> options =
        new FirebaseRecyclerOptions.Builder<image_details>()
                .setQuery(myRef, image_details.class)
                .build();

FirebaseRecyclerAdapter adapter = new FirebaseRecyclerAdapter<image_details, BlogViewHolder>(options) {
    @Override
    public BlogViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View view = LayoutInflater.from(parent.getContext())
                .inflate(R.layout.individual_row, parent, false);

        return new BlogViewHolder(view);
    }

    @Override
    protected void onBindViewHolder(BlogViewHolder holder, int position, image_details model) {
        // Bind the image_details object to the BlogViewHolder
        // ...
    }
};

Finally, the FirebaseRecyclerAdapter uses an event listener to monitor changes to the Firebase query. To begin listening for data, call adapter.startListening() and adapter.stopListening() to stop the listener. It's recommended to call these in onStart() and onStop() respectively. Further details on this are available in the FirebaseRecyclerAdapter lifecycle documentation.

FirebaseRecyclerAdapter() in FirebaseRecyclerAdapter cannot be applied to [wrong arguments]

You are already using the FirebaseRecyclerOptions:

  FirebaseRecyclerOptions<Category> options =
            new FirebaseRecyclerOptions.Builder<Category>()
                    .setQuery(MenuViewHolder, Category.class)
                    .build();

The constructor FirebaseRecyclerAdapter takes a variable of type FirebaseRecyclerOptions as specified here:

https://github.com/firebase/FirebaseUI-Android/blob/master/database/src/main/java/com/firebase/ui/database/FirebaseRecyclerAdapter.java#L37

Change this:

FirebaseRecyclerAdapter adapter = new FirebaseRecyclerAdapter<Category, MenuViewHolder>(Category.class,R.layout.menu_item,MenuViewHolder.class,category) {

into this:

FirebaseRecyclerAdapter adapter = new FirebaseRecyclerAdapter<Category, MenuViewHolder>(options) {

firebaserecycleradapter() in firebaserecycleradapter cannot be applied to

The FirebaseRecyclerAdapter binds a Query to a RecyclerView. When data is added, removed, or changed these updates are automatically applied to your UI in real time.

First, configure the adapter by building FirebaseRecyclerOptions:

 FirebaseRecyclerOptions<Category> options =
                new FirebaseRecyclerOptions.Builder<Category>()
                        .setQuery(category, Category.class)
                        .build();

Next create the FirebaseRecyclerAdapter object. You should already have a ViewHolder subclass for displaying each item.

FirebaseRecyclerAdapter adapter = new FirebaseRecyclerAdapter<Category, MenuViewHolder>(options) {
    @Override
    public ChatHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        // Create a new instance of the ViewHolder, in this case we are using a custom
        // layout called R.layout.menu_item for each item
        View view = LayoutInflater.from(parent.getContext())
                .inflate(R.layout.menu_item, parent, false);

        return new MenuViewHolder(view);
    }

    @Override
    protected void onBindViewHolder(MenuViewHolder holder, int position, Category model) {
        // Bind the Chat object to the ChatHolder
        // ...
    }
};

Why am I getting this error FirebaseRecyclerAdapter() in FirebaseRecyclerAdapter cannot be applied to:

Change this:

FirebaseRecyclerAdapter firebaseRecyclerAdapter = new FirebaseRecyclerAdapter <Posts, PostViewHolder> (
                Posts.class,
                R.layout.posts,
                PostViewHolder.class,
                mDataBase
        )

Into this:

FirebaseRecyclerAdapter firebaseRecyclerAdapter = new FirebaseRecyclerAdapter <Posts, PostViewHolder> (options)

In the new version of Firebaseui, the constructor of FirebaseRecyclerAdapter take a parameter of type FirebaseRecyclerOption which you already initialized

Check the documentation:

https://github.com/firebase/FirebaseUI-Android/blob/master/database/README.md#firebaseui-for-realtime-database

FirebaseRecyclerAdapter cannot be applied

From the error, you are giving wrong arguments. Since you already using the FirebaseRecyclerOptions:

  FirebaseRecyclerOptions<Category> options =
            new FirebaseRecyclerOptions.Builder<Category>()
                    .setQuery(MenuViewHolder, Category.class)
                    .build();

so just change that line to this

FirebaseRecyclerAdapter adapter = new FirebaseRecyclerAdapter<Category, MenuViewHolder>(options) {

Error with constructor FirebaseRecyclerAdapter in class FirebaseRecyclerAdapter

You are getting the following error:

error: constructor FirebaseRecyclerAdapter in class FirebaseRecyclerAdapter cannot be applied to given types; required: FirebaseRecyclerOptions found: Class,int,Class,DatabaseReference reason: actual and formal argument lists differ in length where T,VH are type-variables: T extends Object declared in class FirebaseRecyclerAdapter VH extends ViewHolder declared in class FirebaseRecyclerAdapter

Because you have added one of the latest versions of the Firebase-UI library dependency in your build.gradle file. To be able to create a new object of the FirebaseRecyclerAdapter class, a FirebaseRecyclerOptions object is required. What you are doing, is passing wrong elements to the constructor. That way of creating the adapter was available in the older versions. Now, to create a new object, pass FirebaseRecyclerOptions object, as explained in my answer from the following post:

• How can I retrieve data from Firebase to my adapter
