Android set Full-screen and Cancel Full-screen method

Android offers two ways to achieve no title bar and Full-screen effects, either declaratively through an XML file or dynamically controlled in a program.

Android Set Full-screen method

First, through the program settings:

The code is as follows

Copy Code

package com.hhh.changeimage;     import android.app.Activity;     Import Android.os.Bundle;     import Android.view.Window;     import Android.view.WindowManager;     public class Changeimage extends activity     {     public void OnCreate (Bundle savedinstancestate)     {     super.oncreate ( Savedinstancestate);    //No TITLE     requestwindowfeature (window.feature_no_title);      GetWindow (). SetFlags (WindowManager.LayoutParams.FLAG_FULLSCREEN, Windowmanager.layoutparams. Flag_fullscreen);     Setcontentview (R.layout.main);    }    }

Note: No title and full screen segment code must be before Setcontentview (R.layout.main), or it will be an error.

Second, in the configuration file modification (androidmanifest.xml)

The code is as follows	Copy Code
<activity android:name= ". Changeimage " 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>

Below we combine the above example to make an Android Full-screen setting and cancel the full screen setting

• 1.//Insert before Setcontentview () in Oncreat method

The code is as follows	Copy Code
requestwindowfeature (window.feature_no_title)//Cancel title bar GetWindow (). SetFlags (Windowmanager.layoutparams. Flag_fullscreen, Windowmanager.layoutparams. Flag_fullscreen);/Full Screen

Note: This method flashes the status bar after the activity is started and then full screen
• 2, inside the manifest configuration: <activity android:theme= "@android: Style/theme.notitlebar.fullscreen"/> Only in the current Activity display full screen
<application android:theme= "@android: Style/theme.notitlebar.fullscreen"/> Full screen display for the entire application
• 3,/**
* Full Screen switching
• */

The code is as follows

Copy Code

public void Fullscreenchange () { sharedpreferences mpreferences = preferencemanager.getdefaultsharedpreferences (this); Boolean fullscreen = Mpreferences.getboolean ("fullscreen", false); Windowmanager.layoutparams attrs = GetWindow (). GetAttributes (); System.out.println ("fullscreen value:" + fullscreen); if (fullscreen) { attrs.flags &= (~windowmanager.layoutparams.flag_fullscreen); GetWindow (). SetAttributes (Attrs); //Cancel full screen settings GetWindow (). Clearflags (WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS); · Mpreferences.edit (). Putboolean ("fullscreen", false). commit (); •} else { attrs.flags |= WindowManager.LayoutParams.FLAG_FULLSCREEN; GetWindow (). SetAttributes (Attrs); GetWindow (). Addflags (WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS); Mpreferences.edit (). Putboolean ("fullscreen", true). commit (); •} •}
