SimpleCursorAdapter

类概述

这是一个简单的适配器,通过指定一个定义了视图UIXML文件来创建视图。

构造函数

publicResourceCursorAdapter(Contextcontext, int layout,Cursorc)

构造函数

参数

ContextListView相关的正在运行的SimpleListItemFactory上下文

layout一个定义了列表项视图的布局文件资源ID,这个布局同时定义列表项视图和下拉视图,直到你重写它们。

c获取数据的游标

publicResourceCursorAdapter(Contextcontext,int layout,Cursorc, boolean autoRequery)

构造函数

参数

ContextListView相关的正在运行的SimpleListItemFactory上下文

layout一个定义了列表项视图的布局文件资源ID,这个布局同时定义列表项视图和下拉视图,直到你重写它们。

c获取数据的游标

autoRequery如果此参数为true,当适配器的数据发生变化的时,适配器会调用游标的requery()方法,使最新的数据始终显示

公共方法

publicViewnewDropDownView(Contextcontext,Cursorcursor,ViewGroupparent)

生成一个新的下拉视图来控制游标指向的数据

参数

context应用程序全局信息接口(应用上下文)

cursor获取数据的游标,它已经移动到正确的位置

parent与新视图相关联的上级视图

返回值

新创建的视图

publicViewnewView(Contextcontext,Cursorcursor,ViewGroupparent)

根据指定的xml文件创建视图

参数

context应用程序全局信息接口(应用上下文)

cursor获取数据的游标,它已经移动到正确的位置

parent与新视图相关联的上级视图

返回值

新创建的视图

参见

newView(android.content.Context, android.database.Cursor, ViewGroup)

public voidsetDropDownViewResource(int dropDownLayout)

设置下拉视图相应的布局资源

参数

dropDownLayout用于创建下拉视图的布局资源

public voidsetViewResource(int layout)

设置列表项视图相应的布局资源

参数

layout用于创建列表项视图的布局资源
