為什么80%的碼農(nóng)都做不了架構(gòu)師？>>> ??

聽說作者最近離開Baidu創(chuàng)業(yè)去了，以下是他個人錄制的教程，并非認(rèn)識大神，有好的東西就搬運(yùn)分享一下...

【圖一】

【圖二】

需求:

由于業(yè)務(wù)需求，如上【圖一】閥室，點(diǎn)擊其它類型之后，動態(tài)切換其子分類如上【圖二】閥室-其它所示，(圖表上的數(shù)值并非準(zhǔn)確，方便開發(fā)直接改數(shù)據(jù)庫的)

就是第一層餅圖，顯示大分類，第二層餅圖，顯示大分類的對應(yīng)的子分類...

API:

馬上翻API得知，有公共事件監(jiān)聽,,,官方Demo如下

輪到上映粗狂的需求code:
