You need to initialise list view before you set header view.

something like this

lv = (ListView) findViewById(R.id.list);

then you can add the header view after inflating header view.

View head = (View) getActivity().getLayoutInflater().inflate(R.layout. header_layout, null);
lv.addHeaderView(header);

We Can add header to ListView as below : 

LayoutInflater myinflater = getLayoutInflater();
ViewGroup myHeader = (ViewGroup)myinflater.inflate(R.layout.headerlayout, myListView, false);
myListView.addHeaderView(myHeader, null, false);

But, As per your error you might have taken Relative Layout in your xml and in your java file, You are using LinearLayout.

You also have to initialize your ListView as :

lv=(ListView)findViewById(R.id.yourlistview);`

Add this to your Adapter :

 @Override
    public boolean isEmpty() {
        return false;
    }

Add this to your adapter if you have SectionedBaseAdapter:

 @Override
        public int getCountForSection(int section) {

            switch (section) {

                case 0:
                    return listPOJOInAdapter== null ? 1 : listPOJOInAdapter.size();

            }

            return 1;
        }

And after adding HeaderView to ListView, Try to set Adapter of ListView.

Hopefully it will help you ! Let me know if you get success !
