Three ways to get rid of the title bar in Android apps

There are three ways to get rid of the title bar in Android, and they have their own characteristics.

1. Implement in Code

Remember: This code should be written in front of Setcontentview ().

2. Implemented in the manifest file (manifest.xml)

<application android:icon= "@drawable/icon"          android:label= "@string/app_name"          

<span style= "FONT-FAMILY:VERDANA;FONT-SIZE:18PX;" ><application android:icon= "@drawable/icon"         android:label= "@string/app_name"         android:theme= "@ Android:style/theme.notitlebar "></span>

This can be used to set the entire application to no title bar, if only one activity is set to a untitled bar form, as long as the above the third line of code written to a certain activity inside it.

3. Defined in the Style.xml file

<?xmlversion= "1.0" encoding= "UTF-8"?> <resources>    <style name= "Notitle" >         <item name= " Android:windownotitle ">true</item>    </style>  

<span style= "FONT-FAMILY:VERDANA;FONT-SIZE:18PX;" ><?xml version= "1.0" encoding= "UTF-8"?><resources>    <style name= "Notitle" >        <item Name= "Android:windownotitle" >true</item>    </style> </resources></span>

then the face manifest.xml in the reference, this method is slightly more troublesome.

<applicationandroid:icon= "@drawable/icon"          android:label= "@string/app_name"         

<span style= "FONT-FAMILY:VERDANA;FONT-SIZE:18PX;" ><application android:icon= "@drawable/icon"         android:label= "@string/app_name"         android:theme= "@ Style/notitle "></span>

In fact, it can be seen that the second method is essentially the same as the third method, But the second method calls the system-defined Style.xml file, and the third method is to define the Style.xml in its own application, and then call it by itself, in fact, the truth is the same, the third way to do more sense of accomplishment.
