mLanguageLogoImageView = itemView.findViewById(R.id.language_logo);
mLanguageNameTextView = itemView.findViewById(R.id.language_name);
mLanguageRankTextView = itemView.findViewById(R.id.language_rank);

At first check your all findViewById elements present in respective xml (R.layout.list_item_language)
or not.
