Java CWAC-带阵列适配器的端部适配器
大家都好，在过去的一周里，我一直在试图弄清楚用EndlesAdapter包装我的适配器到底意味着什么，但没有成功。我已经尝试了我有限的知识，到目前为止，我正在输掉这场战斗。我在网上读了几个例子，并阅读了endlessadapter说明，但它并没有真正起到帮助作用。谁能解释一下包装我的适配器的意义吗 我的列表视图如下：Java CWAC-带阵列适配器的端部适配器,java,android,commonsware-cwac,endlessadapter,Java,Android,Commonsware Cwac,Endlessadapter,大家都好，在过去的一周里，我一直在试图弄清楚用EndlesAdapter包装我的适配器到底意味着什么，但没有成功。我已经尝试了我有限的知识，到目前为止，我正在输掉这场战斗。我在网上读了几个例子，并阅读了endlessadapter说明，但它并没有真正起到帮助作用。谁能解释一下包装我的适配器的意义吗 我的列表视图如下： package com.bopbi.ui; import java.sql.Date; import java.text.SimpleDateFormat; import jav
