How can I RecyclerView Different View Selected or UnSelected

I currently use RecyclerView but i can't fix the issue; If user selected a answer, answer in change textview color and background. If user selected different answer first answer old textview color and background.

Codes;

    @Override
public void onBindViewHolder(final ViewHolder holder, int position) {
    _mContext = holder._mAnswersContainer.getContext();
    _mPosition = position;
    holder._mImageAnswer.setImageDrawable(Utils.stringToResource(_mContext,
            _mAnswerList.get(_mPosition).mAnswerImage));
    holder._mImageTextAnswer.setText(_mAnswerList.get(_mPosition).mAnswerText);

    holder._mAnswersContainer.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            holder._mImageTextAnswer.setTextColor(_mContext.getResources()
                    .getColor(R.color.white));
            holder._mImageTextAnswer.setBackgroundColor(_mContext.getResources()
                    .getColor(R.color.red));

            Log.d(TAG, "Values : " + QuestionsHelper.getInstance(_mContext)
                    .getValues(_mAnswerList.get(_mPosition).mAnswerText));

        }
    });
}

Inside your adapter, make a member variable to keep track of which position is selected:

private int mSelected = -1;

Inside your onBindViewHolder (although it might work inside onCreateViewHolder as well):

int color;
if(position == mSelected){
    color = ContextCompat.getColor(context, R.color.selectedColor);
}else{
    color = ContextCompat.getColor(context, R.color.regularColor);
}

// Set the color
viewHolder.yourView.setBackgroundColor(color);

Create some helper functions for your RecyclerView adapter to handle the selection:

public void selectPosition(int selected){
    mSelected = selected;
    notifyDataSetChanged();
}

public void resetSelected(){
    mSelected = -1;
    notifyDataSetChanged();
}

Wherever you want to set the selected item just call adapter.selectPosition(). And clear the selection with adapter.resetSelected()
