android 仿微信demo——微信主界面實(shí)現(xiàn)

 更新時(shí)間：2021年06月17日 15:41:57   作者：你要永遠(yuǎn)相信光z  
本系列文章主要介紹了微信小程序-閱讀小程序?qū)嵗╠emo），小編覺得挺不錯(cuò)的，現(xiàn)在分享給大家，也給大家做個(gè)參考。一起跟隨小編過來看看吧，希望能給你們提供幫助

以往文章中實(shí)現(xiàn)微信啟動(dòng)頁，登錄注冊(cè)功能，此基礎(chǔ)上繼續(xù)完善仿微信功能。

主界面實(shí)現(xiàn)

（1）整體采用RelativeLayout相對(duì)布局

（2）最上面是toolbar操作欄,搜索框SearchView，Overflow（含有4個(gè)單選菜單項(xiàng)）

（3）中間使用Fragment組件（不使用ViewPager，有興趣可以自己添加實(shí)現(xiàn)下）。

（4）最下面是水平的LinearLayout線性布局：含有4個(gè)自定義的控件

在這里插入圖片描述

這一篇主要是實(shí)現(xiàn)主界面，其他像頂部（toolbar,SearchView,Overflow),中間的fragment，后續(xù)文章在更新。
