Technically, you could just do something like this:

ImageButton imageButton = findViewById(R.id.image_button);

if (imageButton1 != null) {
    // if the imagebutton isn't found in the view hierarchy,
    // then don't attempt to manipulate it.
    imagebutton1.setVisibility(View.VISIBLE);
}

Otherwise you can use:

Configuration conf = getResources().getConfiguration();

boolean isLarge = (conf.screenLayout & Configuration.SCREENLAYOUT_SIZE_LARGE) == 
                      Configuration.SCREENLAYOUT_SIZE_LARGE;

boolean isLandscape = (conf.orientation == Configuration.ORIENTATION_LANDSCAPE);

boolean isLargeLand = isLarge && isLandscape;
