listview进行item多选、全选、反选操作。

  Context context;
    List list;

        TextView tv_time, tv_title, tv_jiangshi, tv_fenlei;
        CheckBox isCheakBox;
    }
 
  将点击的item的position保存到map中。 
  
 
  
 @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();
    }
 
  
通过点击事件改编listview的显示。
