How to ensure that we can add a footer to the list in a list fragment

README.md

Sometimes we want to add or remove a fragment after the adapter has been set. This is ok on Kit-Kat but if we are working with compatibility libraries to support earlier versions of Android we can use this to guaranty that the internal ListView wraps the adapter in a HeaderViewListAdapter.

This example show how this can easily handled. The same logic can be used with a stand alone ListView in a custom layout.

HeadListFragment.java

import android.os.Build;

import android.support.v4.app.ListFragment;

public class  HeadListFragment extends ListFragment {

	@Override
	public void setListAdapter(ListAdapter adapter) {
		if (Build.VERSION.SDK_INT <= Build.VERSION_CODES.JELLY_BEAN_MR2) {
			View fixFooter = new View(getActivity());
			getListView().addFooterView(fixFooter);
			super.setListAdapter(adapter);
			getListView().removeFooterView(fixFooter);
		} else {
			super.setListAdapter(adapter);
		}
	}

}
