- 老早就聽說了recycleView喘落，是google在V7包提供的懈叹，以用來替代ListView、gridView的組件缤削。本人以前在IOS4.3的時(shí)候窘哈，寫過ios，對(duì)于目前的ListView組件來說亭敢，確實(shí)可配置的太少滚婉，已經(jīng)無法支撐強(qiáng)大的產(chǎn)品需求和功能，更加無法和ios的tableview抗衡帅刀。
- 本次學(xué)習(xí)計(jì)劃大致會(huì)有幾篇文章让腹，從最開始的使用recycleView远剩，以及高階使用等等。開始會(huì)給code骇窍，讓讀者有個(gè)初探瓜晤，后續(xù)會(huì)對(duì)API進(jìn)行梳理與分析。
