listview进行item多选、全选、反选操作。

<pre name="code" class="html">  Context context;    List<MineCollectionEntity.BodyBean.ElementsBean> list;    boolean isCheck;    // 用来控制CheckBox的选中状况    private static HashMap<Integer, Boolean> isSelected;    public CollectionListAdapter(Context context, List<MineCollectionEntity.BodyBean.ElementsBean> list, boolean isCheck) {        this.context = context;        this.list = list;        this.isCheck = isCheck;        isSelected = new HashMap<Integer, Boolean>();        // 初始化数据        initDate();    }    // 初始化isSelected的数据    public void initDate() {        isSelected = new HashMap<Integer, Boolean>();        for (int i = 0; i < list.size(); i++) {            getIsSelected().put(i, false);        }    }    public static HashMap<Integer, Boolean> getIsSelected() {        return isSelected;    }    public static void setIsSelected(HashMap<Integer, Boolean> isSelected) {        CollectionListAdapter.isSelected = isSelected;    }    public void setIsCheck(boolean isCheck) {        this.isCheck = isCheck;    }    @Override    public int getCount() {        return list.size();    }    @Override    public Object getItem(int position) {        return list.get(position);    }    @Override    public long getItemId(int position) {        return position;    }    @Override    public View getView(final int position, View convertView, ViewGroup parent) {        ViewHolder viewHolder = null;        if (convertView == null) {            viewHolder = new ViewHolder();            convertView = View.inflate(context, R.layout.item_coll, null);            viewHolder.iv_icon = (ImageView) convertView.findViewById(R.id.iv_icon);            viewHolder.isCheakBox = (CheckBox) convertView.findViewById(R.id.isCheakBox);            viewHolder.tv_time = (TextView) convertView.findViewById(R.id.tv_time);            viewHolder.tv_title = (TextView) convertView.findViewById(R.id.tv_title);            viewHolder.tv_jiangshi = (TextView) convertView.findViewById(R.id.tv_jiangshi);            viewHolder.tv_fenlei = (TextView) convertView.findViewById(R.id.tv_fenlei);            convertView.setTag(viewHolder);        } else {            viewHolder = (ViewHolder) convertView.getTag();        }        MineCollectionEntity.BodyBean.ElementsBean bean = list.get(position);        if (!TextUtils.isEmpty(bean.getCourseImgPath())) {            Picasso.with(context).load(bean.getCourseImgPath()).placeholder(R.drawable.home_top).error(R.drawable.home_top).into(viewHolder.iv_icon);        }        if (isCheck) {            viewHolder.isCheakBox.setVisibility(View.VISIBLE);            viewHolder.isCheakBox.setChecked(getIsSelected().get(position));        } else {            viewHolder.isCheakBox.setVisibility(View.GONE);        }        final ViewHolder finalViewHolder = viewHolder;        convertView.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {                finalViewHolder.isCheakBox.setChecked(!finalViewHolder.isCheakBox.isChecked());                getIsSelected().put(position, finalViewHolder.isCheakBox.isChecked());            }        });        viewHolder.isCheakBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {            @Override            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {                getIsSelected().put(position, isChecked);            }        });        viewHolder.tv_time.setText(bean.getDuration());        viewHolder.tv_title.setText(bean.getCourseName());        viewHolder.tv_jiangshi.setText(bean.getAuthorName());        return convertView;    }    class ViewHolder {        ImageView iv_icon;        TextView tv_time, tv_title, tv_jiangshi, tv_fenlei;        CheckBox isCheakBox;    }

将点击的item的position保存到map中。

<pre name="code" class="html"> @OnClick(R.id.tv_all)    public void allClick() {        isAll = !isAll;        if (isAll) {            tv_all.setText("反选");            for (int i = 0; i < list.size(); i++) {                CollectionListAdapter.getIsSelected().put(i, true);            }        } else {            for (int i = 0; i < list.size(); i++) {                tv_all.setText("全选");                if (CollectionListAdapter.getIsSelected().get(i)) {                    CollectionListAdapter.getIsSelected().put(i, false);                } else {                    CollectionListAdapter.getIsSelected().put(i, true);                }            }        }        adapter.notifyDataSetChanged();    }

<span style="font-size:18px;"><strong>通过点击事件改编listview的显示。</strong></span>
