I am using the listview add/remove footer for listview cross app in android version 4.3?

Question

I used to the ListView add the footer view and also remove footer its worked fine in android version 4.4 above but problem in android version 4.3 and below I a

Answer 1

This is probably caused by calling setAdapter() on the ListView before calling setFooterView(). This was necessary in all versions of Android prior to 4.4

Actually, I didn't know this restriction had been relaxed for KitKat until I saw this question... :)

In the sources of addFooterView() for API level 15:

/*
 * NOTE: Call this before calling setAdapter. This is so ListView can wrap
 * the supplied cursor with one that will also account for header and footer
 * views.

Meanwhile, it KitKat, this restriction was relaxed:

/*
 * Note: When first introduced, this method could only be called before
 * setting the adapter with {@link #setAdapter(ListAdapter)}. Starting with
 * {@link android.os.Build.VERSION_CODES#KITKAT}, this method may be
 * called at any time.

If you want to be compatible with pre-4.4, you need to respect the calling order, i.e.

1. addFooterView(footer);
2. setAdapter(adapter);
3. removeFooterView(footer);

Answer 2

Yes. Headers/footers are indeed problematically with backward compatibility. I recently refactored code, to use relative layout instead of a footer, which did pretty much, what I expected on any device -> footer visible, footer gone. Try this with a ListView footer, this will not work, instead you need to call addFooterView, removeFooterView and even this is not working as mentioned. The crash could be circumvented by

a = getAdapter()
setAdapter(null)
removeFooter()
setAdapter(a)

but the footer still was not working that way.
