android - Full screen activity in landscape mode at the same time with configChanges -

in activity, have imageview moves (100, 100) coordinates clicking on it. added following code before setcontentview() in activity have full screen view in landscape mode:

if (getresources().getconfiguration().orientation == configuration.orientation_landscape) {     getwindow().addflags(windowmanager.layoutparams.flag_fullscreen); } else {     getwindow().clearflags(windowmanager.layoutparams.flag_fullscreen); }   

everything works fine , when turn device landscape mode, have fullscreen view. need activity doesn't recreate turning landscape mode. example, if clicked on imageview , moved (100, 100), after going landscape mode should stay on coordinates. this, added line manifest:

android:configchanges="orientation|screensize"   

but adding line manifest, fullscreen property stops working.
can me have these 2 property simultaneous please?
in advance , sorry bad english.

activity :

public class mainactivity extends activity {  @override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     if (getresources().getconfiguration().orientation == configuration.orientation_landscape) {         getwindow().addflags(windowmanager.layoutparams.flag_fullscreen);     }     else {         getwindow().clearflags(windowmanager.layoutparams.flag_fullscreen);     }     setcontentview(r.layout.activity_main);      final imageview imageview = (imageview)findviewbyid(r.id.imageview);     imageview.setonclicklistener(new view.onclicklistener() {         @override         public void onclick(view view) {             imageview.setx(100);             imageview.sety(100);         }     }); } 

}

xml :

<?xml version="1.0" encoding="utf-8"?> <linearlayout xmlns:android="http://schemas.android.com/apk/res/android"     android:id="@+id/activity_main"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:orientation="vertical">     <imageview         android:layout_width="100dp"         android:layout_height="100dp"         android:id="@+id/imageview"         android:background="#000000"/> </linearlayout>   

manifest :

<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.example.test">  <application     android:allowbackup="true"     android:icon="@mipmap/ic_launcher"     android:label="@string/app_name"     android:supportsrtl="true"     android:theme="@style/apptheme">     <activity android:name=".mainactivity"         android:configchanges="orientation|screensize">         <intent-filter>             <action android:name="android.intent.action.main" />              <category android:name="android.intent.category.launcher" />         </intent-filter>     </activity> </application> 

as edson menegatt said, add following code @ end of activity, , problem solved:

@override public void onconfigurationchanged(configuration newconfig) {     super.onconfigurationchanged(newconfig);     // checks orientation of screen     if (newconfig.orientation == configuration.orientation_landscape) {         getwindow().addflags(windowmanager.layoutparams.flag_fullscreen);     } else if (newconfig.orientation == configuration.orientation_portrait){         getwindow().clearflags(windowmanager.layoutparams.flag_fullscreen);     } }   

the codes before setcontentview() wrote in question, necessary too.

thank edson menegatti ...
