Android開發必知 九種對話方塊的實現方法_Android

在開發過程中，與使用者互動式免不了會用到對話方塊以實現更好的使用者體驗，所以掌握幾種對話方塊的實現方法還是非常有必要的。在看具體執行個體之前先對AlertDialog做一個簡單介紹。AlertDialog是功能最豐富、實踐應用最廣的對話方塊，它可以產生各種內容的對話方塊。但實際上AlertDialog產生的對話方塊總體可分為以下4個地區：表徵圖區、標題區、內容區、按鈕區。

這裡總結了九種對話方塊的實現方法，有需要的朋友可以來學習下了

 

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

布局，就是一堆的button
