自定义Dialog经常用到，这里记录一下。前面陈列一下需要做的准备工作，最后一步是使用方式。

<style name="MyDialog" parent="@style/Theme.AppCompat.Dialog"> <!-- 背景颜色及透明程度 --> <item name="android:windowBackground">@android:color/transparent</item> <!-- 是否有标题 --> <item name="android:windowNoTitle">true</item> <!-- 是否浮现在activity之上 --> <item name="android:windowIsFloating">true</item> <!-- 是否模糊 --> <item name="android:backgroundDimEnabled">true</item> </style>----------------------------------------------------------------------------------------------------------------

使用：
new CommonDialog(getActivity(), R.style.MyDialog, new CommonDialog.OnCloseListener() { @Override public void onClick(Dialog dialog, boolean confirm) { //To do what you want } }).setTitle(" 我是标题").setContent("我是内容").show();
可以设置标题，内容，按钮文字，一个按钮或两个按钮，这些都可以通过链式方式设置。
