Two full-screen display modes on the android Interface

In the development of Android applications, we will encounter some interface settings to the full screen display format, there are two ways to achieve. One is implemented in Java code, and the other is implemented in the configuration file.

1. Set in Java code

Super. oncreate (savedinstancestate); requestwindowfeature (window. feature_no_title); // No titlegetwindow (). setflags (windowmanager. layoutparams. flag_fullscreen, windowmanager. layoutparams. flag_fullscreen); // setcontentview (R. layout. main );

Note that the two Java codes must be placed before setcontentview (); otherwise, an error is reported. The error is shown as follows.

2. modify it in the manifest File

Add Android: theme = "@ Android: style/theme. notitlebar. fullscreen" to the default activity.
