    <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:background="#0099cc"
    tools:context=".FullscreenActivity" >

         The primary full-screen view. This can be replaced with whatever view
         is needed to present your content, e.g. VideoView, SurfaceView,

    <TextView

            <Button

                android:text="@string/dummy_button" />
        </LinearLayout>
    </FrameLayout>

</FrameLayout>

the java code, these are three utility codes as well but I think it make the code part too long

You're trying to allow the user to exit/enter fullscreen on longclick?

try:

getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);

and:

getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);

in your listener.
