android - addHeaderView does not work when the list is empty

Question

I am using following layout(header.xml) to add header in a listview,

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/greetingContainer"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

<TextView
    android:id="@+id/categoryTitle"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="header view"
    android:textColor="#FFFFFF"
    android:textSize="15sp" />

</LinearLayout>

and on the other side, i am using,

View header = (View) getLayoutInflater().inflate(R.layout.header,null);
getListView().addHeaderView(header);

when the list is empty it's not working, stays invisible..

my question may be the duplicate of this, but unable to understand,
please help!

Simple solution, all you need to do is that you should ALWAYS set an adapter for your listview, even when you do not have any data to show.
