结构

继承关系

public static interface SimpleCusrorTreeAdapter.ViewBinder

java.lang.Object

android.widget.SimpleCursorTreeAdapter.ViewBinder

类概述

这个内部接口可以在外部通过SimpleCursorTreeAdapter.ViewBinder的方式进行 Cursor与View的绑定。Android推荐我们采用这种方式进行绑定操作，而不是沿用SimpleCursorTreeAdapter内部的方式。

参见

setViewImage(ImageView, String)

setViewText(TextView, String)

公共方法

public abstract boolean setViewValue (View view, Cursor cursor, int columnIndex)

将指定的列数据绑定到指定的视图上。当ViewBinder处理绑定时，这个方法必须返回true；否则SimpleAdapter将尝试通过其内部默认的方法绑定数据。

参数

view 被绑定的视图。

cursor 数据库游标，绑定数据从它这里获取

columnIndex 列位置，能够在数据库游标中寻找到。

返回值

返回true意味着数据与视图已经绑定上，否则为未绑定上。
