How can I change my view in horizontal orientation and then back to portrait?

Question

I want my view to change when it has changed to horizontal orientation:

@Override
    public void onConfigurationChanged(Configuration newConfig) {
      super.onConfigurationChanged(newConfig);
      setContentView(R.layout.chartsactivity);
    }

This works, but I want my layout to switch back when it is in portrait mode.

Answer 1

Just look at the orientation of newConfig and use a different layout in each case? It would be much better if you let the system do it for you though.

Answer 2

To let the system handle the layout change you have to specify a special layout for landscape mode for the layout files you want to look different in landscape mode. This is done through a special folder for landscape layouts. Just put a layout-land folder in your resources folder. If your application is running in landscape mode, and such a folder is present the system will look for layout files in this folder first and if the layout is not found fall back to the standard layout folder.
