这是我的自定义CursorAdapter:

public class TasksAdapter extends CursorAdapter implements Filterable {

    private final Context context;

    public TasksAdapter(Context context, Cursor c) {
        super(context, c);
        this.context = context;
    }

    /**
     * @see android.widget.CursorAdapter#newView(android.content.Context, android.database.Cursor, android.view.ViewGroup)
     */
    @Override
    public View newView(Context context, Cursor cursor, ViewGroup parent) {

        holder.textview = (CheckedTextView)v.findViewById(android.R.id.text1);
        v.setTag(holder);

        return v;
    }

    /**  
     * @see android.widget.CursorAdapter#bindView(android.view.View, android.content.Context, android.database.Cursor)
     */
    @Override

我正在使用CursorAdapter在listview中读取数据库.我在列表的每个项目中都有一个复选框,当用户选中复选框时,我的数据库中的收藏列会更改是,并且项目会添加到收藏夹中.

我该怎么办这个问题:
