Going back to previous Activity from full screen mode

[digitalbuddha]

Based on response on following issue I was able to implement a "always full screen" mode.
#66

For reference I am doing the following

 ((ViewGroup)((ViewGroup)((ViewGroup)((ViewGroup)((ViewGroup)findViewById(R.id.main_layout))
                .getChildAt(0))
                .getChildAt(0))
                .getChildAt(1))
                .getChildAt(2))
                .getChildAt(1)
                .performClick();

Now I'd like to be able to go from the full screen mode directly back to previous activity but cannot find a way to hijack the back button press. I've tried the following to no avail

  @Override
    public boolean onKeyDown(int keyCode, KeyEvent event) {
        if (Integer.parseInt(android.os.Build.VERSION.SDK) > 5
                && keyCode == KeyEvent.KEYCODE_BACK
                && event.getRepeatCount() == 0) {
            onBackPressed();
            return true;
        }
        return super.onKeyDown(keyCode, event);
    }


    @Override
    public void onBackPressed() {
        super.onBackPressed();
        finish();

    }

Any help/suggestions would be appreciated

videoWidgetView.post(new Runnable() {
            @Override
            public void run() {
                videoWidgetView.fullScreenDialog.setOnDismissListener(new DialogInterface.OnDismissListener() {
                    @Override
                    public void onDismiss(DialogInterface dialog) {
                        videoWidgetView.setVisibility(View.INVISIBLE);
                        finish();
                    }
                });
            }
        });

I'm using this to go back to the previous activity from fullscreen mode. I think it's time to add these options to the library.

Thanks for posting this workaround. The demand is pretty obvious for programatic control of view modes, so we're planning to add that in the next release.

@nathanmartz That will be very cool!

With v0.9.0 there's now an official API for this.

How to back from the full screen mode directly to previous activity ??

@hegazy
I tried your code with (VrPanoramaView) but i get error in (fullScreenDialog)

@dav-cz
I don't see how the official API fix this problem.
Exiting the fullscreen mode still does not exit the activity.

@electmk the code from @hegazy worked on older version of the gvr-android-sdk : 1.20.0 for instance.

The new solution is to use the onDisplayModeChanged callback from VrPanoramaEventListener.

@Override
public void onDisplayModeChanged(int newDisplayMode) {
    super.onDisplayModeChanged(newDisplayMode);
    if (newDisplayMode == VrWidgetView.DisplayMode.EMBEDDED) {
        VrPanoramaActivity.this.finish();
    }
}

I got error (Method does not override method from its superclass) when i put the method in VrPanoramaActivity

@electmk as said before the onDisplayModeChanged callback is from VrPanoramaEventListener, not VrPanoramaActivity.

From your VrPanoramaActivity onCreate you should set a VrPanoramaEventListener on your VrPanoramaView :

panoWidgetView = (VrPanoramaView) findViewById(R.id.pano_view);
panoWidgetView.setEventListener(new ActivityEventListener());

Then from this listener, override the onDisplayModeChanged callback

private class ActivityEventListener extends VrPanoramaEventListener {
  @Override
  public void onDisplayModeChanged(int newDisplayMode) {
  [...]

@Awsom3D
It's worked .. thank you
But it shows a black screen for seconds before finish .. Can I avoid this?

@electmk sorry, no clue.
