Android dialogfragment 取消状态栏 android怎么关闭通知栏

推荐方法：在自定义的styles中设置隐藏状态栏和标题栏的theme，并在AndroidManifest.xml文件中的application或某个activity中设置。

styles文件如下

[html]  view plain  copy

1. <resources>  
2.   
3. <!-- Base application theme. -->  
4. <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">  
5. <!-- Customize your theme here. -->  
6. <item name="colorPrimary">@color/colorPrimary</item>  
7. <item name="colorPrimaryDark">@color/colorPrimaryDark</item>  
8. <item name="colorAccent">@color/colorAccent</item>  
9. </style>  
10.   
11. <style name="AppTheme.NoBar">  
12. <item name="windowNoTitle">true</item>  
13. <item name="android:windowFullscreen">true</item>  
14. </style>  
15.   
16. </resources>

AndroidManifest.xml文件如下：

[html]  view plain  copy

1. <?xml version="1.0" encoding="utf-8"?>  
2. <manifest xmlns:android="http://schemas.android.com/apk/res/android"  
3. package="com.jianchi.fsp.myapplication">  
4.   
5. <application  
6. android:allowBackup="true"  
7. android:icon="@mipmap/ic_launcher"  
8. android:label="@string/app_name"  
9. android:supportsRtl="true"  
10. android:theme="@style/AppTheme">  
11. <activity android:name=".MainActivity" android:theme="@style/AppTheme.NoBar">  
12. <intent-filter>  
13. <action android:name="android.intent.action.MAIN" />  
14. <category android:name="android.intent.category.LAUNCHER" />  
15. </intent-filter>  
16. </activity>  
17. </application>  
18.   
19. </manifest>
