Android Programming Set Full Screen Method Example detailed _android

The example in this article describes the way Android programming is set to Full-screen. Share to everyone for your reference, specific as follows:

In real-world application development, we sometimes need to set the activity to a full screen display, in general, there are two ways to set the Full-screen display effect. First, you can set it in code, and second, set the full screen through the manifest configuration file.

First: Set in code (as follows)

Package Xiaohang.zhimeng;
Import android.app.Activity;
Import Android.content.pm.ActivityInfo;
Import Android.os.Bundle;
Import Android.view.Window;
Import Android.view.WindowManager;
public class Activity01 extends activity {
  @Override public
  void OnCreate (Bundle savedinstancestate) {
    Super.oncreate (savedinstancestate);
    Set to no title bar
    requestwindowfeature (window.feature_no_title);
    Set to Full-screen mode
    GetWindow (). SetFlags (WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG _fullscreen);
    Set to horizontal screen
    setrequestedorientation (activityinfo.screen_orientation_landscape);
    Setcontentview (R.layout.main);
  }

But note: Set in the code, set untitled and set the full screen of two pieces of code to be placed in Setcontentview (R.layout.main); In front of this piece of code. Otherwise, it will be an error.

Second: Set up in the manifest configuration file

<?xml version= "1.0" encoding= "Utf-8"?> <manifest xmlns:android=
"http://schemas.android.com/apk/res/" Android "
   package=" Com.ladygaga.playboy "
   android:versioncode=" 1 "
   android:versionname=" 1.0 ">
  <USES-SDK android:minsdkversion= "8"/>
  <application android:icon= "@drawable/icon" @ String/app_name ">
    <activity android:name=" Com.ladygaga.test.ImageSwitcherTest "
         android: Screenorientation= "sensor"
         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>
</manifest>

Or:

<?xml version= "1.0" encoding= "Utf-8"?> <manifest xmlns:android=
"http://schemas.android.com/apk/res/" Android "
   package=" Com.ladygaga.playboy "
   android:versioncode=" 1 "
   android:versionname=" 1.0 ">
  <USES-SDK android:minsdkversion= "8"/>
  <application android:icon= "@drawable/icon"
    android:theme= "@android: Style/theme.notitlebar.fullscreen"
    android:label= "@string/app_name" >
    <activity android: Name= "Com.ladygaga.test.ImageSwitcherTest"
         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>
</manifest>

Add attributes to nodes in the corresponding activity:

Copy Code code as follows:

Android:theme= "@android: Style/theme.notitlebar.fullscreen"

That is, you can set up an activity to display in full screen. If set to Android:theme= "@android: Style/theme.notitlebar" That is only set to no title state.

I hope this article will help you with the Android program.
