How to achieve full screen in Android, remove title bar effect

In the Android UI design, we often need to set the screen to no title bar or full screen. It is very simple to implement, and there are two main ways to do this: Configure the XML file and write code settings.

1. Configuring in an XML file

In the project's manifest file Androidmanifest.xml, find the activity that needs to be full-screen or set to an untitled bar, where the activity is configured as follows.

To achieve full-screen effects:
Android:theme= "@android: Style/theme.notitlebar.fullscreen"
Implement a untitled bar (but with the system's own taskbar):
Android:theme= "@android: Style/theme.notitlebar"
2. Writing Code settings
Write code in the program to set, just add the following code in the OnCreate () method to
To achieve full-screen effects:
GetWindow (). SetFlags (WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
Implement a untitled bar (but with the system's own taskbar):
Requestwindowfeature (Window.feature_no_title);
