2.CustomDialog的样式：

1     <style name="mystyle" parent="@android:style/Theme.Dialog">
2         <item name="android:windowFrame">@null</item>
3         <item name="android:windowIsFloating">true</item>
4         <item name="android:windowIsTranslucent">false</item>
5         <item name="android:windowNoTitle">true</item>
6         <item name="android:windowBackground">@drawable/bg</item>
7         <item name="android:backgroundDimEnabled">true</item>
8     </style>

3.<item name="android:windowBackground">@drawable/bg</item>  -> bg.xml

 1 <?xml version="1.0" encoding="utf-8"?>

19             }
20         });
21         ibuilder.create().show();
22     }

效果如图：

问题：

在使用过程中，当Activity设置为取消标题栏时，会出现CustomDialog变形的情况，如图：

真的很莫名其妙，后面逐一排除比对才找出该原因所在，具体原理不知，恳请知道的大牛评论告知，谢谢。

出现如上问题，是因为：

如下设置取消标题栏：

1         <activity
2             android:name=".CommentDialogActivity"
3             android:label="@string/title_activity_comment"
4             android:screenOrientation="portrait"
5             android:theme="@android:style/Theme.NoTitleBar"
6             android:windowSoftInputMode="adjustUnspecified|adjustResize" >
7         </activity>

而解决该问题，需要使用另一种方式来设置取消标题栏：

1     protected void onCreate(Bundle savedInstanceState) {
2         super.onCreate(savedInstanceState);
3         requestWindowFeature(Window.FEATURE_NO_TITLE);//去掉标题栏
4         setContentView(R.layout.dialog_sendcomments);
5 }

小伙伴们有兴趣可以试一下。
