make a fullScreen in only layout-land android when

问题:

I'm creating android app to play liveStream, I added the videoView in my layout.xml and added the folder of layout-land

I want to make the app shows video full screen in only layout-land not portrait

so I added the following code in onCreate():

public void onConfigurationChanged(Configuration newConfig){
if(getResources().getConfiguration().orientation == Configuration.ORIENTATION_LANDSCAPE
   {
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
   } else 
    if (getResources().getConfiguration().orientation == Configuration.ORIENTATION_PORTRAIT) {
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN,    WindowManager.LayoutParams.FLAG_FULLSCREEN);
    }
}

but my problem is when I rotate the device it restarts the activity and this lead the stream of video to stop and I want to prevent this. So. I added to manifest this line

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

but this leads the code of onCreate() to be executed once only.

How to make my app plays the video stream continuously and when I rotate device to make full screen in layout land then when back to portrait make it normal?

Hope that anyone got my mean. Thanks in advance.

You should add your videoview (or content Parent) as last element in your layout file. and use the next code:

private RelativeLayout.LayoutParams paramsNotFullscreen; //if you're using RelativeLatout           

@Override
public void onConfigurationChanged(Configuration newConfig) 
{
    super.onConfigurationChanged(newConfig);


    if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) //To fullscreen
    {
        paramsNotFullscreen=(RelativeLayout.LayoutParams)mVideoView.getLayoutParams();
        RelativeLayout.LayoutParams params=new LayoutParams(paramsNotFullscreen);
        params.setMargins(0, 0, 0, 0);
        params.height=ViewGroup.LayoutParams.MATCH_PARENT;
        params.width=ViewGroup.LayoutParams.MATCH_PARENT;
        params.addRule(RelativeLayout.CENTER_IN_PARENT);
        mVideoView.setLayoutParams(params);

    } 
    else if (newConfig.orientation == Configuration.ORIENTATION_PORTRAIT) 
    {
        mVideoView.setLayoutParams(paramsNotFullscreen);
    }
}

It gets a copy of videoview layoutparams and saves it in a global variable. then creates a new layoutparams object with the previous values but setting now the limits to match_parent and sets it in your videoview. You videoview now is in fullscreen. When you put your device in portrait, paramsNotFullscreen restores previous values.

UPDATE:

In your manifest file you must add into Activity declaration the following code to avoid the activity restart:

android:configChanges="screenLayout|screenSize|orientation"

try this...

@Override
    public void onConfigurationChanged(Configuration newConfig) 
    {
        super.onConfigurationChanged(newConfig);


        if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) 
        {
            setContentView(R.layout.create_job_l);

        } 
        else if (newConfig.orientation == Configuration.ORIENTATION_PORTRAIT)
        {
            setContentView(R.layout.create_job_p);

        }
    }
    @Override
    public void onCreate(Bundle savedInstanceState)
    {

        super.onCreate(savedInstanceState);
        if (getResources().getConfiguration().orientation == 1)
        {
            setContentView(R.layout.create_job_p);
        }
        if (getResources().getConfiguration().orientation == 2)
        {
            setContentView(R.layout.create_job_l);
        }


    }
