Remove the title bar and status bar from Android Activity

Source: Internet

1. Set in the code

Public void oncreate (bundle savedinstancestate ){
Super. oncreate (savedinstancestate );
// Remove title
Requestwindowfeature (window. feature_no_title );
// Remove the status bar above the activity
Getwindow (). setflags (windowmanager. layoutparams. flag_fullscreen, windowmanager. layoutparams. flag_fullscreen );
Setcontentview (R. layout. Main );
}

Or

Requestwindowfeature (window. feature_custom_title );
Getwindow (). setfeatureint (window. feature_custom_title, R. layout. custom_title_1 );

R. layout. custom_title_1 this is your title file Layout

2. modify the configuration file

(Key code: Android: theme = "@ Android: style/theme. notitlebar. fullscreen ". If you want to remove the title bar, you do not need to add fullscreen. If you want to remove the title bar and status bar for the entire application, add the code to <application .. In the tag, if you only want an activity to work, this code will be added to the corresponding activity ):

To hide the title bar, use the predefined style Android: theme = "@ Android: style/theme. notitlebar ".

Hide the status bar: Android: theme = "@ Android: style/theme. notitlebar. fullscreen ".
Here I also want to explain that after we use the former to run the application, we will see a short status bar before it is full screen. This is not the case in the second method, so I suggest you use the latter!
