# ReactiveProperty.XamarinAndroid

ReactiveProperty.XamarinAndroid is MVVM support library for ReactiveProperty + Xamarin.Android environment.

- Xamarin is [here](https://xamarin.com/).

# Features

- OneWay and TwoWay databinding, between View's property and ReactiveProperty.

- IList, ObservableCollection and ReadOnlyObservableCollection convert to IListAdapter.

- View classes(ex, Button, TextView...) event provide extension method "EventName"AsObservable.

## DataBinding

This ViewModel class is here.

```cs

public class VM

{

  // ViewModel Property

  public ReactiveProperty Output { get; set; }

  public VM() { this.Output = new ReactiveProperty(); }

}

```

### OneWay databinding.

```cs

var vm = new VM();

this.FindViewById(Resource.Id.TextView)

  .SetBinding(

    x => x.Text, // select target property

    vm.Output); // source property

```

### TwoWay databinding

```cs

var vm = new VM();

this.FindViewById(Resource.Id.EditText)

  .SetBinding(

    x => x.Text, // select target property

    vm.Output,  // source property

    x => x.TextChangedAsObservable().ToUnit()); // update source trigger

```

### Command binding

SetCommand extension methods can be found in IObservable .

```cs

this.FindViewById(Resource.Id.Button)

  .ClickAsObservable()

  .SetCommand(vm.AlertCommand);

```

### Collection binding

Collection type can convert to IListAdapter.

```cs

public class VM

{

  public ReadOnlyReactiveCollection Values { get; private set; }

}

var vm = new VM();

this.FindViewById(Resource.Id.ListView)

    .Adapter = vm.Values.ToAdapter(

      (index, value) => LayoutInflator.FromContext(this).Inflate(Android.Resource.Layout.SimpleListItem1) // create view

      (index, value, view) => view.FindViewById(Android.Resource.Id.Text1).Text = value, // setup view

      (index, value) => value.GetHashCode()); // generate id

```
