RecyclerView no recicla vistas cuando lo usa dentro de NestedScrollView
Estoy usandoRecyclerView
dentroNestedScrollView
. También pusesetNestedScrollingEnabled
a falso porrecyclerview
para soportar una API más baja
ViewCompat.setNestedScrollingEnabled(mRecyclerView, false);
¡Ahora! Cuando el usuario desplaza la vista, todo parece estar bien, pero !!! las vistas en la vista de reciclaje no se reciclan !!! ¡Y el tamaño del montón crece rápidamente!
Actualizar: El administrador de diseño RecyclerView esStaggeredLayoutManager

P.s: he configurado cargar más en la vista de desplazamiento, porquerecyclerview
¡Hazlo continuamente y ninguno se puede parar!
Cualquier ayuda es apreciada
