用hashMAP或ArrayList解决recylerView中checkbox的选择错乱问题。

//这个监听一定要放在checkbox初始化的方法之前，否则无效。是因为滑动的时侯会重新给checkbox赋值造成的。
holder.cbFileSel.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
    @Override
    public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
        Log.e("isChecked",isChecked+"---"+position);
        checkedItems.put(position,isChecked);
    }
});

holder.cbFileSel.setChecked(checkedItems.get(position));

集合初始化

private HashMap<Integer,Boolean> checkedItems;
public FileListAdapter(Context context, ArrayList<Files> datas, int layoutID) {
    super(context, datas, layoutID);
    checkedItems=new HashMap<>();
    for(int i=0;i<datas.size();i++){
       checkedItems.put(i,false);
    }
}

方法二：利用arraylist解决

    private List<Integer> checkPositionlist;
    private ArrayList<Files> checkedFiles;
    public PictureSelectorAdapter_1(ArrayList<Files> files, ArrayList<Files> checkedFiles) {
        this.files = files;
        checkPositionlist = new ArrayList<>();
        this.checkedFiles = checkedFiles;
    }

/**
     * 解决checkbox的多选冲突
     * @param holder
     * @param position
     * @param currentFile
     */
    private void checkboxMulConflict(final MyViewHolder holder, final int position, final Files currentFile) {
        holder.checkbox.setTag(new Integer(position));//防止复用导致的checkbox多选的问题。
        //防止复选的辅助list
        if (checkPositionlist != null) {
            holder.checkbox.setChecked((checkPositionlist.contains(new Integer(position)) ? true : false));
        } else {
            holder.checkbox.setChecked(false);
        }

        holder.checkbox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                if (isChecked) {
                    if (!checkPositionlist.contains(holder.checkbox.getTag())) {
                        checkPositionlist.add(new Integer(position));
                        checkedFiles.add(currentFile);
                    }
                } else {
                    if (checkPositionlist.contains(holder.checkbox.getTag())) {
                        checkPositionlist.remove(holder.checkbox.getTag());
                        checkedFiles.remove(currentFile);
                    }
                }
            }
        });
    }
