Answer 1

Don't use onClickListener in onBindViewHolder instead set it in onCreateViewHolder and create a member variable to set the selected item. You can do it like this.
int mSelectedItemPosition = -1;
// in your createViewHolder method
holder.linearLayoutChannelName.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View view){
int position = holder.getAdapterPosition();
if (position != RecyclerView.NO_POSITION) {
mSelectedItemPosition = position;
notifyItemRangeChanged(0, yourList.size());
}
}
});
And in your bind view holder check selected item position and set the background color
if(mSelectedItemPosition == position){
view.setBackgroundColor(Color.parseColor("#yourColor"))
}else{
view.setBackgroundColor(Color.parseColor("originalColor"));
}
