getview method is not calling in custom listview method in android

I am having an Arraylist as [x,y,z..]. I want this ArrayList [x,y,z..] in ListView but getview() method is not getting invoked
I am trying this code :

public class CustomAdapter extends BaseAdapter
{
public static ArrayList<String> arr=new ArrayList<String>();

public Context Context;
private LayoutInflater inflater;

HashMap<String, String> map = new HashMap<String, String>();
public CustomAdapter(Context context, ArrayList<String> arr) 
{
    Context=context;
    inflater=LayoutInflater.from(context);
    arr=arr;

}
public int getCount() 
{
    // TODO Auto-generated method stub
    return arr.size();
}

public Object getItem(int position) 
{
    // TODO Auto-generated method stub
    return arr.get(position);
}

public long getItemId(int position) 
{
    // TODO Auto-generated method stub
    return position;
}

public View getView(int position, View convertView, ViewGroup parent) 
    {
    System.out.println(arr.get(posstion));
        ViewHolder holder;

        if (convertView == null) 
        {
            convertView = inflater.inflate(R.layout.selecteditemlistview, null);
            holder = new ViewHolder();

   holder.textViewSelectedText = (TextView)convertView.findViewById(R.id.selectedtext);
            convertView.setTag(holder);
        }
        else 
        {
            holder = (ViewHolder) convertView.getTag();
        }

        holder.textViewSelectedText.setText(arr.get(position));
        return convertView;
    }

    class ViewHolder
    {
        TextView textViewSelectedText = null;
    }
}

System.out.println(arr.get(posstion));

This line is inside getview() method and it is not printing the values.. please help me.

You should use the setAdapter function on the ListView to let it use your custom adapter

EDIT: There is a typo in the CustomAdapter constructor: the code should read

this.arr = arr

instead of

arr = arr

inside ur getview method your sop is System.out.println(arr.get(posstion));. i think it should be System.out.println(arr.get(position));
because in your getview method int position is defined and not posstion. check the spelling in your code

public View getView(int position, View convertView, ViewGroup parent){
   System.out.println(arr.get(position));
}

even if this doesnt work try giving sop in 

public CustomAdapter(Context context, ArrayList<String> arr) 
{     
   Context=context;  
   inflater=LayoutInflater.from(context);  
   arr=arr;  
   System.out.println("arr: " + arr.size);

}

if size is 0 then u r not getting any result from activity classto this adapter

You have wrongly spelled the position change 

System.out.println(arr.get(posstion));

by 

System.out.println(arr.get(position));
