Question

I have a simple activity with a boolean. I want it to change from portrait to landscape if and only if that boolean is false (only if the screen changes orientation, of course).

I tried this:

    @Override
    public void onConfigurationChanged(final Configuration newConfig) {
        super.onConfigurationChanged((listening) ? getListeningConfiguration(newConfig)
                : newConfig);
        setContentView(R.layout.medidor);
        preconfigureLayout();
    }

    public Configuration getListeningConfiguration(final Configuration c) {
        c.orientation = Configuration.ORIENTATION_PORTRAIT;
        return c;
    }

But it simply won’t work.

How can I force an activity to remain in portrait state unless I tell it it can change?

Answer 1

Just call this to keep it in portrait:

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

That should do the trick
