Answer 1

Just replace the original ListView with your CustomListView Layout within the onCreateView method. Worked for me.

    @Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    View layout = super.onCreateView(inflater, container,
            savedInstanceState);
    ListView lv = (ListView) layout.findViewById(android.R.id.list);
    ViewGroup parent = (ViewGroup) lv.getParent();

    // Remove ListView and add CustomView  in its place
    int lvIndex = parent.indexOfChild(lv);
    parent.removeViewAt(lvIndex);
    LinearLayout mLinearLayout = (LinearLayout) inflater.inflate(
            R.layout.custom_list, container, false);
    parent.addView(mLinearLayout, lvIndex, lv.getLayoutParams());
    return layout;
}

Answer 2

A little bit late, but did not see this answer.

Inside Fragment:

    @Override
    public View onCreateView(final LayoutInflater inflater, final ViewGroup container,
            final Bundle savedInstanceState) {
        final View view = inflater.inflate(R.layout.fragment_list_activity,
                container, false);  

        ListFragmentHelper.adaptView(view);

        return view;
    }

but bear in mind that in fragment_list_activity.xml you need to set the IDs android:id="@id/loading", android:id="@id/content" and android:id="@id/empty" for your views!

This code worked for me:

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View root = super.onCreateView(inflater, container, savedInstanceState);

    ((TextView)root.findViewById(0x00ff0001)).setText("some text");

    ListView list = (ListView) root.findViewById(android.R.id.list);
    list.setEmptyView(root.findViewById(0x00ff0001));

    return root;
}

Answer 4

I just needed to change my empty text TextView properties and did this

@Override
public void onLoadFinished(Loader<Cursor> loader, Cursor cursor) {
    // Swap the new cursor in. (The framework will take care of closing the
    // old cursor once we return)
    mAdapter.swapCursor(cursor);
    if (cursor.getCount() == 0) {
        setEmptyText(getString(R.string.no_users));
        TextView tvEmpty = (TextView) getListView().getEmptyView();
        tvEmpty.setTextColor(getResources().getColor(R.color.blue));
    }
    // The list should now be shown.
    if (isResumed()) {
        setListShown(true);
    } else {
        setListShownNoAnimation(true);
    }
}

Do not forget that if you try initializing tvEmpty before you call setEmptyText("Empty"), you'll run into a NullPointerException

Answer 5

This might be easier: Create your layout as you would normally but don't add the list/empty/loading stuff. Then in your listfragment's onCreateView:

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View v = super.onCreateView(inflater, container, savedInstanceState);
    ViewGroup parent = (ViewGroup) inflater.inflate(R.layout.mylayout, container, false);
    parent.addView(v, 0);
    return parent;
}

Now you can use setListShown...

Today I had the same issue. Looking the solution in Google, I found a post in a japanese blog. (http://blog.nkzn.net/entry/2012/06/14/160706).

For use setListShown(boolean) you must do first in your layout:

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

    <FrameLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <ListView
        android:id="@android:id/list"
        android:layout_width="match_parent"
        android:layout_height="match_parent" >
    </ListView>
    </FrameLayout>

    <LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_centerInParent="true"
    android:gravity="center"
    android:visibility="gone" >

    <ProgressBar
        android:id="@android:id/progress"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />
    </LinearLayout>
</RelativeLayout>

Now in your ListFragment:

public class SampleListFragment extends ListFragment {

  /** ID for progressbar parent */
  private static final int INTERNAL_PROGRESS_CONTAINER_ID = 0x00ff0002;
  /** ID for listview parent */
  private static final int INTERNAL_LIST_CONTAINER_ID = 0x00ff0003;

  @Override
  public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.custom_list_layout, container, false);

    // get you progressBar and his parent
    ProgressBar pBar = (ProgressBar) view.findViewById(android.R.id.progress);
    LinearLayout pframe = (LinearLayout) pBar.getParent();
    pframe.setId(INTERNAL_PROGRESS_CONTAINER_ID);

    ListView listView = (ListView) view.findViewById(android.R.id.list);
    listView.setItemsCanFocus(false);
    FrameLayout lFrame = (FrameLayout) listView.getParent();
    lFrame.setId(INTERNAL_LIST_CONTAINER_ID);    

    return view;
  } 
}

with this 2 ids numbers seted in his parents setListShown(boolean) will work without problems.
