问题 On Android, I have a header with a background image (Random image according to API). On this header I have texts with some data. My text is every time black but sometimes image is black too.

问题 At First, my RecyclerView items are ok, but on scrolling, items are shown on the wrong position for example: item 6 shown in position 67. Although onClick listener and getAdapterPosition() works good and shows correct items. WHY? import android.content.Context; import android.graphics.Typeface; import android.support.v7.widget.RecyclerView; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.widget.TextView; import com.neganet.darotabii
