    TextView tv;
    String[]  counting={"One","Two","Three","Four"};
    @Override
    protected void onCreate(Bundle savedInstanceState)
        {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
            sp=new Spinner(this);
            tv=(TextView)findViewById(R.id.spinner1);
            tv.setOnClickListener(new OnClickListener()
                {                       
                    @Override
                    public void onClick(View v)
                        {
                            sp.performClick();
                        }
                });
            sp.setAdapter(new Adapter(MainActivity.this, counting));
            sp.setOnItemSelectedListener(new OnItemSelectedListener()
                {
                    @Override
                    public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2, long arg3)
                        {
                            tv.setText(counting[arg2]);
                        }
                    @Override
                    public void onNothingSelected(AdapterView<?> arg0)
                        {
                        }
                });
        }
}

and adapter class named Adapter.java

public class Adapter extends BaseAdapter
{
    LayoutInflater inflator;
    String[] mCounting;

    public Adapter( Context context ,String[] counting)
        {
            inflator = LayoutInflater.from(context);
            mCounting=counting;
        }

    @Override
    public int getCount()
        {
            return mCounting.length;
        }

    @Override
    public Object getItem(int position)
        {
            return null;
        }

    @Override
    public long getItemId(int position)
        {
            return 0;
        }

    @Override
    public View getView(int position, View convertView, ViewGroup parent)
        {
            convertView = inflator.inflate(R.layout.spinadapt, null);
            TextView tv = (TextView) convertView.findViewById(R.id.tvCust);
            tv.setText(Integer.toString(position));
            return convertView;
        }
}

this is working perfect

hope this will help
