EDITObserver Observables implementing issueを参照してください。私は、setChanged（）を呼び出す必要がないメソッドをオーバーライドしていたようです。 before notify（）;Observable/Observer Android
私はUIを最新の状態に保つためにObserver Patternを読んできましたが、私はまだそれを見ることができません。私の特定のオブジェクトがMainActivityに通知しても、update（）;メソッド私はまだオブジェクトがOncreateで作成されているので、更新オブジェクトの値を取得するためにペットオブジェクトを使用することはできません...そして、変数が異なるために新しいオブジェクトを作成できません。これは私です実装されており、動作していないようです。

update法と呼ばれるPetオブジェクトへの参照を持っている必要がありますか？ v = wiQdrH2YpT4 –
