SimpleAdapter.ViewBinder

翻译时间:2010-11-25

 

结构

继承关系

public static interface SimpleAdapter.ViewBinder

 

android.widget.SimpleAdapter.ViewBinder

 

类概述

SimpleAdapter的外部数据(external clients)可以使用这个类将值绑定到视图。你应该用这个类绑定值到那些不能直接通过SimpleAdapter支持的视图,或者改变通过SimpleAdapter支持绑定的方法的视图。

(译者注:如果SimpleAdapter设置了ViewBinder则使用Viewbinder的绑定规则,否则使用SimpleAdapter的默认绑定规则)

 

公共方法

public abstract boolean setViewValue (View view, Object data, String textRepresentation)

绑定指定数据到指定的视图。 当通过调用ViewBinder绑定数据时,此方法必须返回真。如果这个方法返回假,SimpleAdapter将尝试通过其内部默认的方法绑定数据。

       参数

              view       要绑定数据的视图

data        要绑定到视图的数据

textRepresentation     一个表示所支持数据的安全的字符串:结果是data.toString()或者空字符串,但不会是null

              返回值

                     如果数据绑定到视图返回真,否则返回假。
