In Android, you can set full screen !!!

During development, we often need to set our applications to full screen. Here I know two methods. One is to set them in code, another way is to change it in the configuration file!

1. Set in the Code:

View plaincopy to clipboardprint?
Package com. Android. tutor;
Import Android. App. activity;
Import Android. OS. Bundle;
Import Android. View. window;
Import Android. View. windowmanager;
Public class opengl_lesson1 extends activity {
Public void oncreate (bundle savedinstancestate ){
Super. oncreate (savedinstancestate );
// No title
Requestwindowfeature (window. feature_no_title );
// Full screen
Getwindow (). setflags (windowmanager. layoutparams. flag_fullscreen,
Windowmanager. layoutparams. flag_fullscreen );

Setcontentview (R. layout. Main );
}
}
Package com. Android. tutor;
Import Android. App. activity;
Import Android. OS. Bundle;
Import Android. View. window;
Import Android. View. windowmanager;
Public class opengl_lesson1 extends activity {
Public void oncreate (bundle savedinstancestate ){
Super. oncreate (savedinstancestate );
// No title
Requestwindowfeature (window. feature_no_title );
// Full screen
Getwindow (). setflags (windowmanager. layoutparams. flag_fullscreen,
Windowmanager. layoutparams. flag_fullscreen );

Setcontentview (R. layout. Main );
}
}

It should be emphasized that the full screen code must be before setcontentview (R. layout. Main), or an error will be reported.

2. modify it in the configuration file (Android: theme = "@ Android: style/theme. notitlebar. fullscreen "):

View plaincopy to clipboardprint?
<? XML version = "1.0" encoding = "UTF-8"?>
<Manifest xmlns: Android = "http://schemas.android.com/apk/res/android
"
Package = "com. Android. Tutor"
Android: versioncode = "1"
Android: versionname = "1.0" type = "codeph" text = "/codeph">
<Application Android: icon = "@ drawable/icon" Android: Label = "@ string/app_name">
<Activity android: name = ". OpenGl_Lesson1"
Android: theme = "@ android: style/Theme. NoTitleBar. Fullscreen"
Android: label = "@ string/app_name">
<Intent-filter>
<Action android: name = "android. intent. action. MAIN"/>
<Category android: name = "android. intent. category. LAUNCHER"/>
</Intent-filter>
</Activity>
</Application>
<Uses-SDK Android: minsdkversion = "7"/>
</Manifest>
<? XML version = "1.0" encoding = "UTF-8"?>
<Manifest xmlns: Android = "http://schemas.android.com/apk/res/android
"
Package = "com. Android. Tutor"
Android: versioncode = "1"
Android: versionname = "1.0" type = "codeph" text = "/codeph">
<Application Android: icon = "@ drawable/icon" Android: Label = "@ string/app_name">
<Activity Android: Name = ". opengl_lesson1"
Android: theme = "@ Android: style/theme. notitlebar. fullscreen"
Android: Label = "@ string/app_name">
<Intent-filter>
<Action Android: Name = "android. Intent. Action. Main"/>
<Category Android: Name = "android. Intent. Category. launcher"/>
</Intent-filter>
</Activity>
</Application>
<Uses-SDK Android: minsdkversion = "7"/>
</Manifest>

Here I would like to explain that the former will see a short status bar after we run the application, and then the full screen will be displayed. This is not the case in the second method, so I suggest

Use the latter! Thank you ~

 

The full screen method of the program is known to all. It is static and stated at the beginning of the program running. However, if you want to execute an operation while running the program to make it full screen, you still need to exit full screen. How can this problem be solved?

The Java code is as follows:

Windowmanager. layoutparams attrs = getwindow (). getattributes ();
Attrs. Flags | = windowmanager. layoutparams. flag_fullscreen;
Getwindow (). setattributes (attrs );
Getwindow (). addflags (windowmanager. layoutparams. flag_layout_no_limits );

Modify the layoutparams parameter of the window and add the flag_layout_no_limits flag to it. Window is automatically displayed in full screen mode.

To exit full screen, you only need to clear the flag_fullscreen parameter that you just added, and then remove the flag_layout_no_limits flag.

The Java code is as follows:

Windowmanager. layoutparams attrs = getwindow (). getattributes ();
Attrs. Flags & = (~ Windowmanager. layoutparams. flag_fullscreen );
Getwindow (). setattributes (attrs );
Getwindow (). clearflags (windowmanager. layoutparams. flag_layout_no_limits );
