Set full screen for Android

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:

 

[Java]
View plaincopy

1. Package com. Android. tutor;
2. Import Android. App. activity;
3. Import Android. OS. Bundle;
4. Import Android. View. window;
5. Import Android. View. windowmanager;
6. Public class opengl_lesson1 extends activity {
7. Public void oncreate (bundle savedinstancestate ){
8. Super. oncreate (savedinstancestate );
9. // No title
10. Requestwindowfeature (window. feature_no_title );
11. // Full screen
12. Getwindow (). setflags (windowmanager. layoutparams. flag_fullscreen,
13. Windowmanager. layoutparams. flag_fullscreen );
15. Setcontentview (R. layout. Main );
16. }
17. }

 

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 "):

 

[Java]
View plaincopy

1. <? XML version = "1.0" encoding = "UTF-8"?>
2. <Manifest xmlns: Android = "http://schemas.android.com/apk/res/android"
3. Package = "com. Android. Tutor"
4. Android: versioncode = "1"
5. Android: versionname = "1.0" type = "codeph" text = "/codeph">
6. <Application Android: icon = "@ drawable/icon" Android: Label = "@ string/app_name">
7. <Activity Android: Name = ". opengl_lesson1"
8. Android: theme = "@ Android: style/theme. notitlebar. fullscreen"
9. Android: Label = "@ string/app_name">
10. <Intent-filter>
11. <Action Android: Name = "android. Intent. Action. Main"/>
12. <Category Android: Name = "android. Intent. Category. launcher"/>
13. </Intent-filter>
14. </Activity>
15. </Application>
16. <Uses-SDK Android: minsdkversion = "7"/>
17. </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
