Android開發(fā)必知 九種對話框的實現(xiàn)方法
在開發(fā)過程中,與用戶交互式免不了會用到對話框以實現(xiàn)更好的用戶體驗,所以掌握幾種對話框的實現(xiàn)方法還是非常有必要的。在看具體實例之前先對AlertDialog做一個簡單介紹。AlertDialog是功能最豐富、實踐應(yīng)用最廣的對話框,它可以生成各種內(nèi)容的對話框。但實際上AlertDialog生成的對話框總體可分為以下4個區(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)了九種對話框的實現(xiàn)方法,有需要的朋友可以來學(xué)習(xí)下了




除了popupwindow實現(xiàn)稍微麻煩一點,其他形似都相對簡單,熟悉2便即可
