I need to change the color of a LinearLayout, as per a Firebase query.
Bank Structure:
USUARIOS
- ID_USUARIO
---AGENDAMENTOS
-----nome: João
-----lastview_usuario: "1506816888384"
-----timestamp_update: "1506816951405"
I am retrieving the data and displaying it in a RecyclerView / Cardview. It is working properly.
Problem:
I have a LinearLayou at the top of CardView.
Iwouldliketocomparethelastview_userandtimestamp_updatefields.Ifitisdifferent,setacolorforthebackground.Inthatcase,black.
IcreatedthesetNotificationCard()methodtomakethebackgroundchange.
Somethingiswrong.Accordingtomycode,itonlyupdatesthefirstdatainthelist.
Forexample:Thiscolorfulitemhasitstimestamp_updateandlastview_user,identical.Itwasnotsupposedtocolor.
