How to detect orientation change in layout in Android?

Question

I just implemented a orientation change feature - e.g. when the layout changes from portrait to landscape (or vice versa). How can I detect when the orientation change event

For loading the layout in layout-land folder means you have two separate layouts then you have to make setContentView in onConfigurationChanged method.

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

    // Checks the orientation of the screen
    if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) {
        setContentView(R.layout.yourxmlinlayout-land);
    } else if (newConfig.orientation == Configuration.ORIENTATION_PORTRAIT){
        setContentView(R.layout.yourxmlinlayoutfolder);
    }
}

If you have only one layout then no necessary to make setContentView in This method. simply

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