Full Screen without title bar for Android

This post is reproduced, not prepared by myself.

 

During the UI design, we often need to set the screen to no title bar or full screen. It is also very easy to implement. There are two main methods: Configuring XML files and writingCode.

1.In the XML fileConfiguration

In the androidmanifest. xml file of the project, find the activity that needs to be full screen or set to no title bar.Configure the activity as follows.

Achieve full screen effect:

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

Implement a task bar without a title bar (but with a built-in taskbar ):

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

2.Write code settings
InProgramYou only need to add the following code to the oncreate () method.

Achieve full screen effect:

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

Implement a task bar without a title bar (but with a built-in taskbar ):

 
Requestwindowfeature (window. feature_no_title );
