Ich arbeite an RecyclerView, wo ich ratindBar auf meine Ansichten habe. Problem ist, dass, wenn ich nach unten scrolle, mein RatingBar-Listener immer wieder anruft. Ich stelle unten einen Adapterklassencode zur Verfügung. Ich habe eine Methode, die mehrere Male aufruft, wenn ich scrolle, in der Tat muss es nur Anruf sein, wenn ich Bewertungsleiste berühre.RatingBar Listener ruft beim Scrollen Recycler View
Vielen Dank im Voraus.
