Android開(kāi)發(fā)實(shí)現(xiàn)仿京東商品搜索選項(xiàng)卡彈窗功能
更新時(shí)間：2017年11月21日 11:49:47 作者：勤修戒定慧
這篇文章主要介紹了Android開(kāi)發(fā)實(shí)現(xiàn)仿京東商品搜索選項(xiàng)卡彈窗功能,涉及Android布局及事件響應(yīng)相關(guān)操作技巧,需要的朋友可以參考下
本文實(shí)例講述了Android開(kāi)發(fā)實(shí)現(xiàn)仿京東商品搜索選項(xiàng)卡彈窗功能。分享給大家供大家參考，具體如下：
一、效果圖：
二、思路：
（1）首先頂部布局由通過(guò)LinearLayout水平按比重平均分配各個(gè)item寬度。
（2）每個(gè)item設(shè)置兩種狀態(tài)，點(diǎn)擊狀態(tài)與未點(diǎn)擊狀態(tài)
（3）彈窗由PopupWindow實(shí)現(xiàn)
三、布局
（1）item布局
