working with footerview of listview

I have a listview with footerview. I have added setOnClickListener for listview. If I click the list row it will display a toast message. everything working fine. But my problem is suppose if I press the footerview (I didn't need, But there is possibility to user click it) the application get crashed. I dont know how to resolve this problem. I am tried to control with the view type. Bit I dont know how to find a view is TextView or not?(My footerview is a TextView). Is there any possiblity to solve this Issue.

What I am want?

if user clicked on the footerview nothing should happen.

ListView lv1 = (ListView) findViewById(R.id.myListView);

ListAdapter adapter = new SimpleAdapter(this, mylist, R.layout.txnlist,
                new String[] { "name", "mark"}, new int[] {
                        R.id.text1, R.id.text2 }) {
            @Override
            public View getView(int position, View convertView, ViewGroup parent) {
                View v = convertView;
                if (v == null) {
                    LayoutInflater vi = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
                    v = vi.inflate(R.layout.txnlist, null);
                }
                Collection<Object> str = mylist.get(position).values();
                ArrayList<Object> al1 = new ArrayList<Object>(str);
                TextView amnt = (TextView) v.findViewById(R.id.txntext2);
                if (Integer.parseInt(al1.get(1).toString()) == 1)
                    amnt.setTextColor(Color.GREEN);
                else if (Integer.parseInt(al1.get(1).toString()) == 2)
                    amnt.setTextColor(Color.RED);
                return super.getView(position, v, parent);
            }
        };
TextView MyText = new TextView(this);
MyText.setText("Finished");
lv1.addFooterView(MYText);
lv1.setAdapter(adapter);

setOnClickListener coding

lv1.setOnItemClickListener(new OnItemClickListener() {

public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,long arg3) {

Collection<Object> str = mylist.get(arg2).values();
ArrayList<Object> al1 = new ArrayList<Object>(str);

Toast.makeText(getApplicationContext(),al1.get(0)+" : "+al1.get(1), Toast.LENGTH_SHORT).show();

}
});

And My logcat is:

Every row has two strings except footerview. So I want to ignore the click event of footerview. Is it possible?

Thanks in advance.

Toast.makeText(getApplicationContext(),al1.get(0)+" : "+al1.get(1), Toast.LENGTH_SHORT).show();

Make sure that 

Collection<Object> str = mylist.get(arg2).values();

The size of str is always greater that 1.

if(al1.size() > 1)
{
    Toast.makeText(getApplicationContext(),al1.get(0)+" : "+al1.get(1), Toast.LENGTH_SHORT).show();
}

Or 

ListView#addHeaderView(View v, Object data, boolean isSelectable);

Use this method to make the header or footer View not clickable.
