Getting position of seekbar from recyclerview?

Question

quick question since my other question never got answered. I have a RecyclerView which gets populated with a SeekBar for every item (CardView). I would like to know the best way to get this SeekBar's position.

In other words, how would I be able to differentiate the first seekbar from the second seekbar if there are two items in the recyclerview each containing its own SeekBar?

Also, if this helps any, the listener for said SeekBar is in my Adapter.

Sample of code upon request:

class ViewHolder extends RecyclerView.ViewHolder {
    private TextView mName, mUsername, mPercent;
    private SeekBar mSeekBar;

    ViewHolder(View itemView) {
        super(itemView);
        mName = (TextView) itemView.findViewById(R.id.name_view_members);
        mUsername = (TextView) itemView.findViewById(R.id.username_view_members);
        mPercent = (TextView) itemView.findViewById(R.id.percent_text);
        mSeekBar = (SeekBar) itemView.findViewById(R.id.percent_seekbar);
    }
}
@Override
public void onBindViewHolder(final ViewHolder holder, final int position) {
    GroupMembers individual = mMembers.get(position);
    holder.mName.setText(individual.getName());
    holder.mUsername.setText(individual.getUsername());

    //SeekBar Listener
    holder.mSeekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
        @Override
        public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {

            //Find out which SeekBar triggered the event
            int which = whichIsIt(seekBar.getId(), progress);

            //Stored progress (where is it at)
            int storedProgress = mAllProgress.get(which);

            /**Two cases can occur: User goes left or right with the thumb.
             * If RIGHT, we must check how much he's allowed to go in that
             * direction (based on other seekbars), and stop him before it's
             * too late. If LEFT, free up the space to allow the other seekbars.
             **/
            if (progress > storedProgress) {
                //How much remains based on all seekbars.
                int remaining = remaining();
                //If progress 100%, don't let user move. (overextend)
                if (remaining == 0) {
                    seekBar.setProgress(storedProgress);
                } else {
                    //Progress available, check the availability of others,
                    //and let the user move as long as it's below 100% total.
                    if (storedProgress + remaining >= progress) {
                        mAllProgress.set(which, progress);
                    } else {
                        mAllProgress.set(which, storedProgress + remaining);
                    }
                }
            } else if (progress <= storedProgress) {
                mAllProgress.set(which, progress);
            }
        }

        private int whichIsIt(int id, int progress) {
            holder.mPercent.setText(" " + progress + "%");
            return R.id.percent_seekbar;
        }

        private int remaining() {
            int remaining = TOTAL_AMOUNT;
            for (int i = 0; i < mAllProgress.size(); i++) {
                remaining -= mAllProgress.get(i);
            }
            if (remaining >= 100) {
                remaining = 100;
            } else if (remaining <= 0) {
                remaining = 0;
            }
            return remaining;
        }

        @Override
        public void onStartTrackingTouch(SeekBar seekBar) {
        }

        @Override
        public void onStopTrackingTouch(SeekBar seekBar) {
        }
    });

The method whichIsIt should determine which SeekBar of the RecyclerView is being triggered.

Answer 1

You can set a tag for each seekBar with the position in the adapter seekBar.setTag(holderPosition);

So in the method onProgressChanged(SeekBar seekBar,...) you do seekBar.getTag(). This way you can change your data in the right position.

P.S: If OnSeekBarChangeListener is the same for all seekBars you can create a private field with it. ;)
