一.普通对话框

二.进度条对话框

三.列表对话框

四.时间对话框

五.日期对话框

六.自定义对话框

七.dialogActivity

步骤：

1.创建Activity

2.编写style.xml

3.修改AndroidManifest.xml文件中activity主题

<?xml version="1.0" encoding="utf-8"?>
<resources>
   <style name="dialog_style" parent="@style/AppTheme">
       <!--是否悬浮在activity上-->
       <item name="android:windowIsFloating">true</item>
       <!--是否透明-->
       <item name="android:windowIsTranslucent">true</item>
       <item name="android:title">"activity dialog"</item>
       <item name="android:dialogTitle">"对话框标题"</item>
   </style>
</resources>

   <activity android:name=".MainActivity" android:theme="@style/dialog_style">
           <intent-filter>
               <action android:name="android.intent.action.MAIN" />
               <category android:name="android.intent.category.LAUNCHER" />
           </intent-filter>
       </activity>
