Android使用光标适配器保存ListView中的复选框状态

使用光标适配器时,我无法找到保存复选框状态的方法.其他一切工作正常,但如果我点击一个复选框,它会被重复使用.我见过使用数组适配器的例子,但由于我缺乏经验,我发现很难将其转换为使用游标适配器.有人可以给我一个如何去做的例子.任何帮助赞赏.

private class PostimageAdapter extends CursorAdapter {

    private static final int s = 0;
    private int layout;
    Bitmap bm=null;

        super(context,c);
        this.layout = layout;
        PostNumber = Postid;

     mDbHelper = new TourDbAdapter(context);
     mDbHelper.open();

    }
