Tengo un error: setOnItemClickListener no se puede utilizar con un spinner, ¿qué está mal?

Por favor Este es mi código de abajo, y estoy pegando los mensajes de error debajo: Estoy tratando de usar setOnItemClickListener en el hilandero, ¿es permisible?

 @Override public void onItemClick(AdapterView<?> arg0, View v, int index, long arg3) { if (quantity[index]=="Meter" ){ s1="Meter"; Toast.makeText(v.getContext(), "convert from meter",Toast.LENGTH_SHORT).show(); } } }); convertto.setOnItemClickListener(new OnItemClickListener() { @Override public void onItemClick(AdapterView<?> arg, View v1, int index1, long arg4) { if ((quantity[index1]=="Meter") && (s1.equalsIgnoreCase("Meter"))) { Toast.makeText(v1.getContext(), " to meter",Toast.LENGTH_SHORT).show(); var2=var1; lresult.setText("" + var2); } } }); } }
