How to find out latitude and longitude from address which get from spinner in android

Question

How to find out latitude and longitude from the address...

Here's the code for the spinner where we get the value of address

       landmark_addprod.setOnItemSelectedListener(new OnItemSelectedListener(){
        public void onItemSelected(AdapterView<?> parent, View view, int pos,long id)
        {
            // ListView Clicked item value
            itemValue_landmark = (String) landmark_addprod.getItemAtPosition(pos);
        }

and here get the value of city

            public void onItemSelected(AdapterView<?> parent, View view, int pos,long id)
            {
                itemPosition_city = pos;

                  // ListView Clicked item value
                   itemValue_city = (String) city_addprod.getItemAtPosition(pos);
            }

So how to concatenate the address and city values and how to find out lat longitude from that???

also used--

                Geocoder coder = new Geocoder(addproducts.this);
             try 
                {
            ArrayList<Address> adresses = (ArrayList<Address>) coder.getFromLocationName(itemValue_landmark + itemValue_city, 1);
            for(Address add : adresses){
                    longitude = add.getLongitude();
                    latitude = add.getLatitude();
                } 
            }
        catch (IOException e) {
                e.printStackTrace();
            }

but get the latitude and longitude 0.0
