如何在recyclerview

Question

这个问题在这个thread中有所回答，但我需要它才能工作，因为许多项目都在recyclerview中。例如，如果我在recyclerview中有三个项目，我希望三个搜索栏相互依赖，最多总计100％（或者只是100）。

这是我的代码，它位于自定义适配器中：

public class MembersAdapter extends RecyclerView.Adapter<MembersAdapter.ViewHolder> {
//Tag
private static String TAG = "MembersAdapter";

//Max amount for all seekbars.
private final int TOTAL_AMOUNT = 100;
private final List<Integer> mAllProgress = new ArrayList<>();
private List<GroupMembers> mMembers;

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);
    }
}

/**
 * Constructor
 *
 * @param members : The members.
 */
public MembersAdapter(List<GroupMembers> members) {
    this.mMembers = members;
}

@Override
public MembersAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.row_layout_members, parent, false);
    return new ViewHolder(v);
}

@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());

    //mAllProgress AMOUNTS equal to the SIZE or NUMBER of mMembers which exist.


    //All SeekBars of size mMembers (members picked) should be 0% by default.
    for (int i = 0; i <= mMembers.size() - 1; i++) {
        mAllProgress.add(0);
    }

    //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) {
            switch (id) {
                case R.id.percent_seekbar:
                    holder.mPercent.setText(" " + progress + "%");
                    //This should return the SeekBars position out of however many seekbars there are.
                    return 0;
                default:
                    throw new IllegalStateException(
                            "There should be a seekbar with this id(" + id + ")!");
            }
        }

        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) {

        }
    });
}

@Override
public int getItemCount() {
    return mMembers.size();
}

正如您所知，代码与我链接的代码非常相似，因为我想看看它是否可以在进行一些更改时起作用。例如，我到目前为止所尝试的内容是List<Integer>，其中包含所有进度，并且通过循环遍历它们已设置为0，但有许多mMembers。换句话说，如果有3 mMembers（recyclerview中的项目），那么将有3个搜索栏从0开始。

我相信我需要处理的代码就在这里：

switch (id) {
            case R.id.percent_seekbar:
                holder.mPercent.setText(" " + progress + "%");
                //This should return the SeekBars position out of however many seekbars there are.
                return 0;
            default:
                throw new IllegalStateException(
                        "There should be a seekbar with this id(" + id + ")!");
        }

我知道这就是问题所在的原因是因为返回的ID总是为0.所以我应该如何解决这个问题，这样我才能抓住所有存在的搜索栏，而不是只抓住第一个位置？我试过设置某种类型的计数器，但我主要考虑的是我将如何遍历搜索栏的所有位置...

编辑：这是一个看起来如何的图片示例。显然它不应该是100％和50％，而是50％和50％。

而不是print(tokyo_time.replace(tzinfo=None)) print("hour: " + tokyo_time.hour) 传递return 0;它将起作用
