This example explains how to set Application to fullscreen in android.
Algorithm:
1.) Create a new project by File-> New -> Android Project name it FullScreenDemo.
2.) Write following into main.xml:
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent" android:layout_height="match_parent"
>
<view class="com.example.FullScreenDemo.FullScreenDemo$IV"
android:id="@+id/image"
android:src="@drawable/skycubemap2"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scaleType="center"
/>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="25dp"
android:layout_marginRight="25dp"
android:layout_marginBottom="25dp"
android:layout_gravity="bottom|center"
android:background="#60000000"
android:padding="8dp"
android:orientation="horizontal"
>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:orientation="vertical"
>
<TextView
android:id="@+id/text1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#FFFFFFFF"
android:textSize="16dp"
android:textStyle="bold"
android:gravity="left"
/>
<TextView
android:id="@+id/text2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#FFFFFFFF"
android:textSize="11dp"
android:textStyle="bold"
android:gravity="left"
/>
</LinearLayout>
<TextView
android:id="@+id/switchy"
android:background="#C0000000"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
android:layout_marginTop="4dp"
android:padding="10dp"
android:textColor="#FFFFFFFF"
android:textSize="11dp"
android:textStyle="bold"
android:clickable="true"
android:onClick="clicked"
android:text="Switch"
/>
</LinearLayout>
</FrameLayout>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent" android:layout_height="match_parent"
>
<view class="com.example.FullScreenDemo.FullScreenDemo$IV"

android:layout_height="wrap_content"
android:layout_marginLeft="25dp"
android:layout_marginRight="25dp"
android:layout_marginBottom="25dp"
android:layout_gravity="bottom|center"
android:background="#60000000"
android:padding="8dp"
android:orientation="horizontal"
>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:orientation="vertical"
>
<TextView
android:id="@+id/text1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#FFFFFFFF"
android:textSize="16dp"
android:textStyle="bold"
android:gravity="left"
/>
<TextView
android:id="@+id/text2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#FFFFFFFF"
android:textSize="11dp"
android:textStyle="bold"
android:gravity="left"
/>
</LinearLayout>
<TextView
android:id="@+id/switchy"
android:background="#C0000000"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
android:layout_marginTop="4dp"
android:padding="10dp"
android:textColor="#FFFFFFFF"
android:textSize="11dp"
android:textStyle="bold"
android:clickable="true"
android:onClick="clicked"
android:text="Switch"
/>
</LinearLayout>
</FrameLayout>
3.) Select a wallpaper or background image and put it into drawable folder. Either rename the image “skycubemap2” or change the name into main.xml accordingly.
4.) Run for output.
Steps:
1.) Create a project named FullScreenDemo and set the information as stated in the image.
Build Target: Android 4.0
Application Name: FullScreenDemo
Package Name: com. example. FullScreenDemo
Activity Name: FullScreenDemo
Min SDK Version: 14
2.) Open FullScreenDemo.java file and write following code there:
package com.example.FullScreenDemo;
import android.app.Activity;
import android.content.Context;
import android.os.Bundle;
import android.util.AttributeSet;
import android.view.View;

}

}
private void setFullscreen(boolean on) {

} else {

}
win.setAttributes(winParams);
}
static int TOAST_LENGTH = 500;
IV mImage;
TextView mText1, mText2;
State mState;
IV mImage;

State mState;
public FullScreenDemo() {
}
}
@Override
public void onCreate(Bundle savedInstanceState) {

setContentView(R.layout.main);
mImage = (IV) findViewById(R.id.image);
mImage.setActivity(this);
mText1 = (TextView) findViewById(R.id.text1);
mText2 = (TextView) findViewById(R.id.text2);
}
mImage = (IV) findViewById(R.id.image);
mImage.setActivity(this);

}
@Override
public void onAttachedToWindow() {

}
public void onAttachedToWindow() {
mState = new NormalState();
mState.apply();
}
@Override
protected void onResume() {
super.onResume();
}
protected void onResume() {
super.onResume();
}
3.) Compile and build the project.
