I have an android application that basically scan a barcode. I have a lists of items and I would like to change a color of my list once the item has been scanned.
Please find the image below for reference.
I would like to change a background color of item to red only if the item remaining is zero. There is a item remaining filed on the right side.
I am not sure how to achieve this.

Please provide code of adapter for batter understanding. you can do it by conditioning in your recyclerView
for example:
In onBindViewHolder function:
@Override public void onBindViewHolder(@NonNull ViewHolder holder, int position) { //Get current item's model from Arraylist ScanModel scanModel = list.get(position); int remainingNumber = scanModel.getRemainigNumber(); if(remaingNumber>1) { //change background color to white or whatever you have. holder.rvBackground. setBackgroundColor(Color.parseColor("#FFFFFF")); } else { //Change color to red holder.rvBackground. setBackgroundColor(Color.parseColor("#ffffff")); } //Rest of your code..... }
