The Droid-Fu library has a class designed for having a loading footer show and hide: ListAdapterWithProgress.

Answer 3

As @YoniSamlan pointed out, it can be achieved in a simple way. You have to specify

android:layout_height="wrap_content" 

in the ViewGroup that contains the "Load More" button. Doesn't have to be FrameLayout, see below for a simple -working- example that uses a LinearLayout.

Both images show a screen that is scrolled all the way to the bottom. First one has a visible footer that wraps around the "load more" button. Second images shows that the footer collapses if you set button's visibility to GONE.

You can show again the footer (inside some callback) by changing the visibility:

loadMore.setVisibility(View.VISIBLE);  // set to View.GONE to hide it again

Perform listView initialization as usual

    // Find View, set empty View if needed
    mListView = (ListView) root.findViewById(R.id.reservations_search_results);
    mListView.setEmptyView(root.findViewById(R.id.search_reservations_list_empty));

    // Instantiate footerView using a LayoutInflater and add to listView
    footerView = ((LayoutInflater) getActivity().getSystemService(Context.LAYOUT_INFLATER_SERVICE))
            .inflate(R.layout.load_more_footer_view, null, false);
    // additionally, find the "load more button" inside the footer view
    loadMore = footerView.findViewById(R.id.load_more);
    loadMore.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            fetchData();
        }
    });

    // add footer view to the list
    mListView.addFooterView(footerView);

    // after we're done setting the footerView, we can setAdapter
    adapter = new ReservationsArrayAdapter(getActivity(), R.layout.list_item_reservations_search, reservationsList);
    mListView.setAdapter(adapter);

load_more_footer_view.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content">

<Button
    android:id="@+id/load_more"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_margin="9dp"
    android:gravity="center"
    android:layout_gravity="center"
    android:background="@drawable/transparent_white_border"
    android:textColor="@android:color/white"
    android:text="@string/LOAD_MORE"/>

Answer 4

Used

footer.removeAllViews();

This does not remove footer but flushes children. You again have to repopulate children. Can check by

footer.getChildCount()<2

Answer 5

It should be a bug of Android.

You don't need to remove or add footer view dynamically. You just need to create an unspecified height parent Layout (either inflate it from an xml file or create it programatically) and then add your view which you want to hide or show into it.

And you can set the view, but NOT the parent Layout, to VISIBLE or GONE or something else now. It works for me.

Answer 6

Works well in my project:

1.Add footer view first

mListView.addFooterView(mFooterView); mListView.setAdapter(mAdapter);

2.Set visibility

mFooterView.setVisibility(View.GONE); mFooterView.setPadding(0, 0, 0, 0);

3.Set invisibility

mFooterView.setVisibility(View.GONE); mFooterView.setPadding(0, -1*mFooterView.getHeight(), 0, 0);
