realm-android-adaptersでListView/RecyclerViewを実装すると楽

More than 3 years have passed since last update.

Realmを使って永続化されているデータをListViewやRecyclerViewに表示するアプリケーションをつくるのに便利なのが realm-android-adapters です、という話です。

https://github.com/realm/realm-android-adapters

実装を読むと簡単に仕組みはわかるけど、LiveなOrderedRealmCollectionをAdapterに食わせておくと、別スレッドでDBに変更が加わるとOrderedRealmCollectionChangeListenerに通知が飛んでくるのでそれをきっかけにしてAdapter自身で適切にnotifyDataSetChangedなどを呼んでViewの更新を行ってくれる。

詳しい実装はREADMEを。
