# Android Data Binding + RecyclerView

Using Recyclerview with the new Android Data Binding framework.

## How to start?

Just clone this repository and start playing with it! If you want to use some parts of this repository in your project read below.

### Change your gradle file

- In your main  build.gradle add:

 

```gradle

classpath 'com.android.tools.build:gradle:1.5.0'

```

- In your app build.gradle add:

    

    

```gradle

    dataBinding {

        enabled = true

    }

```

### Modify your layout

Remember to use your classes and packages ;-).

 ```xml

 

 

     

               

     

 

 

 ```

### Modify your activity

```java

	// your activity

	@Override

    protected void onCreate(Bundle savedInstanceState)

    {

        super.onCreate(savedInstanceState);

        usersViewModel = new UsersViewModel();

        usersViewModel.users.add(new SuperUserViewModel(new User("Android", "Dev")));

        binding = DataBindingUtil.setContentView(this, R.layout.users_view);

        binding.setUsersViewModel(usersViewModel);

        binding.activityUsersRecycler.setLayoutManager(new LinearLayoutManager(this));

    }

```

### Modify your ViewModel class

```java

    public class UsersViewModel extends BaseObservable

    {

        public ObservableArrayList users;

        public ItemBinder itemViewBinder()

            {

                return new ItemBinderBase(BR.user, R.layout.item_user);

            }

    }

```

### Some details

Your ViewModel (__UsersViewModel__  in my example) should have field of __ObservableArrayList__ type which will be bind to  recycler view. 

Next thing is __ItemViewBinder__. This class is used in  __BindingRecyclerViewAdapter__ for creating ViewHolders and it's item views bindings. In my example I've created __CompositeItemBinder__ in order to support two different item types with separate layouts. If you want to display list with one data type you can use ItemBinderBase:

```java

	public ItemBinder itemViewBinder()

    {

          return new ItemBinderBase(BR.your_variable_name, R.layout.your_item_layout);

    }

```

Please look at **UsersView.java** and **UsersViewModel.java** if something is unclear.
