SimpleCursorAdapter.ViewBinder

版本：Android 3.0 r1

 

结构

继承关系

public static interface SimpleCusrorAdapter.ViewBinder

 

java.lang.Object

android.widget.SimpleCursorAdapter.ViewBinder

 

类概述

         这个内部接口可以在外部通过SimpleCursorAdapter.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SimpleCursorAdapter内部的方式。

         参见

              bindView(android.view.View, android.content.Context, android.database.Cursor)

                  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处理时，这个方法必须返回true。如果这个方法返回false， SimpleCursorAdapter将用自己的方式进行绑定操作。

                   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。
