Full-screen goes out when switching to portrait

问题

I am using Youtube API for android app and I'm looking for a way to avoid exiting full-screen mode while switching between landscape modes. Meaning, I don't want to exit full-screen mode while switching the phone to portrait mode. I need the video to always be on full-screen.

Is there a way to make it happen?

My current code for full screen is:

@Override
    public void onInitializationSuccess(YouTubePlayer.Provider provider,
            YouTubePlayer player, boolean wasRestored) {
        if (!wasRestored) {
            Intent intent = getIntent();
            String Video_Link = intent.getStringExtra("youtube_id");
            player.cueVideo(Video_Link);
            player.setFullscreen(true);
        }
    }

Thanks a lot in advance.

On an orientation change, the onCreate method is called. You could try adding this line within the Activity in question in your Manifest file to prevent the onCreate call.

    android:configChanges="orientation|keyboardHidden|screenSize|layoutDirection"

and it might maintain the fullscreen status of youtube for you...

otherwise you might try overriding the onconfigchange method:

@Override //reconfigure display properties on screen rotation
    public void onConfigurationChanged(Configuration newConfig) {
        super.onConfigurationChanged(newConfig);

            //Checks the orientation of the screen
            if (newConfig.orientation == Configuration.ORIENTATION_PORTRAIT) 
                {
                // handle change here
                } 
            else if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE)
                {
                // or here
                }
    }

In my situation the activity needed to be in portrait orientation but the video in landscape at all times.

As Will Thomson mentioned above you'll want to add this to your manifest:

android:configChanges="orientation|keyboardHidden|screenSize"

This may not be the ideal way to do things but does what I need.
You can set a fullscreen listener after initialization:

@Override
public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer player, boolean wasRestored) {

    this.player = player;
    player.setOnFullscreenListener(this);

    if(!wasRestored) {
        player.cueVideo(Constants.INTO_YOUTUBE_VIDEO_ID);
    }
}

Then in the callback you can manually set the orientation:

@Override
public void onFullscreen(boolean fullscreen) { 

    videoIsFullScreen = fullscreen;

    if(fullscreen) {
        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
    }
    else {
        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
    }
}

When the user taps play you can use player.setFullscreen(true). When the user taps the back button you can exit fullscreen or finish the activity.

@Override
public void onBackPressed() {
    if(player != null && videoIsFullScreen) {
        player.setFullscreen(false);
    }
    else {
        super.onBackPressed();
    }
}

There's another similar answer here https://stackoverflow.com/a/39494759/1159930 but following the first comment played the video in fullscreen portrait mode rather than landscape.
