類概述

擴(kuò)展自Adapter 的適配器是在Spinner與數(shù)據(jù)之間的一座橋梁。一個Spinner Adapter允許定義兩個不同的視圖：一是在Spinner上顯示數(shù)據(jù)，另一個是當(dāng)Spinner按下時在下拉列表里顯示數(shù)據(jù)。

?

公共方法

public abstract View getDropDownView (int position, View convertView, ViewGroup parent)

獲得一個在指定位置上顯示下拉彈出數(shù)據(jù)的視圖。

參數(shù)

?????? position? 項(xiàng)目視圖的索引

convertView? 如果可能舊有的視圖重新使用。注解：在使用之前應(yīng)該檢查這個視圖不是空的并且類型合適。如果轉(zhuǎn)換視圖顯示正確的數(shù)據(jù)是不可能的，這個方法能夠創(chuàng)建一個新的視圖

parent??? 視圖最終將依附的父對象

返回值

一個對應(yīng)指定位置的數(shù)據(jù)的視圖
