Android開(kāi)發(fā)必知九種對(duì)話框的實(shí)現(xiàn)方法

更新時(shí)間：2015年08月13日 10:31:21 投稿：mrr

App中少不了與用戶交互的各種dialog，以此達(dá)到很好的用戶體驗(yàn)，下面給大家介紹Android開(kāi)發(fā)必知九種對(duì)話框的實(shí)現(xiàn)方法，有需要的朋友可以參考下

在開(kāi)發(fā)過(guò)程中，與用戶交互式免不了會(huì)用到對(duì)話框以實(shí)現(xiàn)更好的用戶體驗(yàn)，所以掌握幾種對(duì)話框的實(shí)現(xiàn)方法還是非常有必要的。在看具體實(shí)例之前先對(duì)AlertDialog做一個(gè)簡(jiǎn)單介紹。AlertDialog是功能最豐富、實(shí)踐應(yīng)用最廣的對(duì)話框，它可以生成各種內(nèi)容的對(duì)話框。但實(shí)際上AlertDialog生成的對(duì)話框總體可分為以下4個(gè)區(qū)域：圖標(biāo)區(qū)、標(biāo)題區(qū)、內(nèi)容區(qū)、按鈕區(qū)。

這里總結(jié)了九種對(duì)話框的實(shí)現(xiàn)方法，有需要的朋友可以來(lái)學(xué)習(xí)下了

除了popupwindow實(shí)現(xiàn)稍微麻煩一點(diǎn)，其他形似都相對(duì)簡(jiǎn)單，熟悉2便即可
