Android中WIFI開發(fā)總結(jié)（二）

展開全文

搞了好幾天終于有點(diǎn)眉目了，這里接著總結(jié)一下Android中WiFi的使用，在前面（http://www./pro/html/201312/7978.html）我們已經(jīng)簡(jiǎn)單了解了Wifi實(shí)際操作中所用到的幾個(gè)主要類，今天就剖析一個(gè)WIFI搜索、創(chuàng)建、關(guān)閉、連接及一些簡(jiǎn)單的動(dòng)畫的綜合案例。（源碼來(lái)源于網(wǎng)絡(luò)，我也忘了。。。經(jīng)本人重構(gòu)、注釋完成！）

首先，我們還是看一下我們項(xiàng)目的框架

MainActivity類：（處理wifi消息，加載UI）

貌似有點(diǎn)長(zhǎng)。。。簡(jiǎn)單說(shuō)明一下：
1.首先，初始化主界面（xml有些復(fù)雜，慢慢理一下就好了，不是什么大問題）接下來(lái)，處理三個(gè)重要的按鈕事件：右上角的搜索wifi按鈕、中間創(chuàng)建或關(guān)閉熱點(diǎn)按鈕、對(duì)話框中確定按鈕。處理前兩者事件時(shí)，需關(guān)注當(dāng)前wifi狀態(tài)，若為占用，需彈出提醒對(duì)話框來(lái)根據(jù)當(dāng)前WiFi操作（WFOperateEnum類中定義好了）事件，來(lái)創(chuàng)建、關(guān)閉、搜索等具體事務(wù)。
2.之所以定義廣播接收者，是為了監(jiān)聽當(dāng)wifi狀態(tài)發(fā)生變化時(shí)，能夠及時(shí)更新界面

廣播接收者WIFIBroadcast類:
