Remove the title bar of Android and disable full screen

Remove the title bar:

 
<ApplicationAndroid: icon= "@ Drawable/icon"Android: Label= "@ String/app_name"Android: Theme= "@ Android: style/theme. notitlebar">
 

OrCodeIn:

 
Requestwindowfeature (window. feature_no_title );//Remove title bar
 

Note that this sentence must be written before the setcontentview () method. Otherwise, an error will be reported. And sometimes you will seeProgramThe title bar disappears after startup.

Remove the title bar from the custom topic: Create style. XML in the Res/values directory.

 <? XML version = "1.0" encoding = "UTF-8"  ?>  <  Resources  >  <  Style  Name  = "Notitle"  >  <  Item  Name  = "Android: windownotitle"  > True </ Item  >  </  Style  >  </  Resources  > 

Then define it in the androidmanifest. xml file

 
<ApplicationAndroid: icon= "@ Drawable/icon"Android: Label= "@ String/app_name"Android: Theme= "@ Style/notitle" >
 

The three methods are of course the first, the simplest and easiest.

Full Screen Persistence: three methods are available:

 
Getwindow (). setflags (windowmanager. layoutparams. flag_fullscreen, windowmanager. layoutparams. flag_fullscreen );
 

 
Android: theme = "@ Android: style/theme. notitlebar. fullscreen"
 

 
<ApplicationApplication= ""Android: icon= "@ Drawable/icon"Android: Label= "@ String/app_name"Android: Theme= "@ Style/fullscreem" >
