how can i pass this info?

In the following list.java i am making a URL near the bottom that grabs the current lo开发者_Python百科cation and adds it to the URL. I have a PHP script taking the location from the URL and then doing its thing and returning a Array based off JSON. I need to get the URL string to be accessed in the HttpPost located in the oncreate area of my Code.

public class List extends ListActivity {

    int ct_id;
    String[] ct_number = null;
    String[] ct_address = null;
    String[] ct_phone = null;
    String[] ct_fax = null;
    String[] ct_email = null;
    String[] ct_city = null;
    String[] ct_province = null;
    String[] ct_country = null;
    String[] ct_pcode = null;
    String[] ct_lat = null;
    String[] ct_long = null;
    String[] ct_distance = null;
    String[] ct_show = null;
    String[] ct_listinfo = null;

    MyLocation myLocation = new MyLocation();

    public void onCreate(Bundle bundle) {
        super.onCreate(bundle);
        setContentView(R.layout.timslist);
        findCurrentLocation();

        String result = null;
        InputStream is = null;
        StringBuilder sb = null;
        //http post
        try{

            HttpClient httpclient = new DefaultHttpClient();

                    //This is where i need the myurl string to be accessed
            HttpPost httppost = new HttpPost(Need_the_myurl_String_here);

            //httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
            HttpResponse response = httpclient.execute(httppost);
            HttpEntity entity = response.getEntity();
            is = entity.getContent();
        }catch(Exception e){
            Log.e("log_tag", "Error in http connection"+e.toString());
        }
        //convert response to string
        try{
            BufferedReader reader = new BufferedReader(new InputStreamReader(is,"iso-8859-1"),8);
            sb = new StringBuilder();
            sb.append(reader.readLine() + "\n");
            String line="0";
            while ((line = reader.readLine()) != null) {
                sb.append(line + "\n");
            }
            is.close();
            result=sb.toString();
        }catch(Exception e){
            Log.e("log_tag", "Error converting result"+e.toString());
        }
        //paring data
        JSONArray jArray;
        try{
            jArray = new JSONArray(result);
            JSONObject json_data=null;
            ct_number=new String[jArray.length()];

                ct_id=json_data.getInt("location_id");

                ct_listinfo[i] = new String (ct_address[i] + "\n" + ct_city[i] + ", " + ct_province[i] + " - " + ct_distance[i] + " Km Away");
            }
        }
        catch(JSONException e1){
            Toast.makeText(getBaseContext(), "No Locations Found" ,Toast.LENGTH_LONG).show();
        } catch (ParseException e1) {
            e1.printStackTrace();
        }

        setListAdapter(new ArrayAdapter<String>(this,R.layout.listview,ct_listinfo));
        ListView lv;
        lv = getListView();
        lv.setTextFilterEnabled(true);
        lv.setCacheColorHint(Color.TRANSPARENT);
        lv.setBackgroundColor(Color.TRANSPARENT);
        lv.setOnItemClickListener(new OnItemClickListener() {
            public void onItemClick(AdapterView<?> timslist, View view,
                    int position, long id) {

                Intent i = new Intent(getApplicationContext(), ListMore.class);

                i.putExtra("ct_number_pass", ct_number[position]);
                i.putExtra("ct_address_pass", ct_address[position]);

                startActivity(i);

            }
        });
    }

    private void findCurrentLocation() {
        myLocation.getLocation(this, locationResult);
    }

    public LocationResult locationResult = new LocationResult() {

        @Override
        public void gotLocation(Location location) {
            // TODO Auto-generated method stub
            if (location != null) {

                    //Here is the String i am trying to access
                String myurl  = "http://www.doamin.com/list.php?lat=" + location.getLatitude() + "&long=" + location.getLongitude();

            }
        }
    };
}

I have tried with the help of others but cant seem to get this working right so i am trying to see if there is a easy and workable solution out there.


You can't do this: you are trying to access the location value BEFORE it is returned to you. You should:

  1. Add a Handler instance to your class.
  2. Move the HttpClient/HttpPost calls into a separate method.
  3. Send a Message to the Handler from the gotLocation method with the location data.
  4. Call that method from the Handler with the location data from step 3 above.

EDIT: try creating a method like this:

void updateData(String url)
{
        String result = null;
        InputStream is = null;
        StringBuilder sb = null;
        //http post
        try{

            HttpClient httpclient = new DefaultHttpClient();

                    //This is where i need the myurl string to be accessed
            HttpPost httppost = new HttpPost(url);

            //httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
            HttpResponse response = httpclient.execute(httppost);
            HttpEntity entity = response.getEntity();
            is = entity.getContent();
        }catch(Exception e){
            Log.e("log_tag", "Error in http connection"+e.toString());
        }
        //convert response to string
        try{
            BufferedReader reader = new BufferedReader(new InputStreamReader(is,"iso-8859-1"),8);
            sb = new StringBuilder();
            sb.append(reader.readLine() + "\n");
            String line="0";
            while ((line = reader.readLine()) != null) {
                sb.append(line + "\n");
            }
            is.close();
            result=sb.toString();
        }catch(Exception e){
            Log.e("log_tag", "Error converting result"+e.toString());
        }
        //paring data
        JSONArray jArray;
        try{
            jArray = new JSONArray(result);
            JSONObject json_data=null;
            ct_number=new String[jArray.length()];
            ct_address=new String[jArray.length()];
            ct_phone=new String[jArray.length()];
            ct_fax=new String[jArray.length()];
            ct_email=new String[jArray.length()];
            ct_city=new String[jArray.length()];
            ct_province=new String[jArray.length()];
            ct_country=new String[jArray.length()];
            ct_pcode=new String[jArray.length()];
            ct_lat=new String[jArray.length()];
            ct_long=new String[jArray.length()];
            ct_distance=new String[jArray.length()];
            ct_listinfo=new String[jArray.length()];
            for(int i=0;i<jArray.length();i++){
                json_data = jArray.getJSONObject(i);
                ct_id=json_data.getInt("location_id");
                ct_number[i]=json_data.getString("store_number");
                ct_address[i]=json_data.getString("store_address");
                ct_phone[i]=json_data.getString("store_phone");
                ct_fax[i]=json_data.getString("store_fax");
                ct_email[i]=json_data.getString("store_email");
                ct_city[i]=json_data.getString("store_city");
                ct_province[i]=json_data.getString("store_province");
                ct_country[i]=json_data.getString("store_country");
                ct_pcode[i]=json_data.getString("store_pcode");
                ct_lat[i]=json_data.getString("store_lat");
                ct_long[i]=json_data.getString("store_long");
                ct_distance[i]=json_data.getString("store_distance");
                ct_listinfo[i] = new String (ct_address[i] + "\n" + ct_city[i] + ", " + ct_province[i] + " - " + ct_distance[i] + " Km Away");
            }
        }
        catch(JSONException e1){
            Toast.makeText(getBaseContext(), "No Locations Found" ,Toast.LENGTH_LONG).show();
        } catch (ParseException e1) {
            e1.printStackTrace();
        }

        setListAdapter(new ArrayAdapter<String>(this,R.layout.listview,ct_listinfo));
        ListView lv;
        lv = getListView();
        lv.setTextFilterEnabled(true);
        lv.setCacheColorHint(Color.TRANSPARENT);
        lv.setBackgroundColor(Color.TRANSPARENT);
        lv.setOnItemClickListener(new OnItemClickListener() {
            public void onItemClick(AdapterView<?> timslist, View view,
                    int position, long id) {

                Intent i = new Intent(getApplicationContext(), ListMore.class);

                i.putExtra("ct_number_pass", ct_number[position]);
                i.putExtra("ct_address_pass", ct_address[position]);
                i.putExtra("ct_phone_pass", ct_phone[position]);
                i.putExtra("ct_city_pass", ct_city[position]);
                i.putExtra("ct_province_pass", ct_province[position]);
                i.putExtra("ct_country_pass", ct_country[position]);
                i.putExtra("ct_pcode_pass", ct_pcode[position]);
                i.putExtra("ct_distance_pass", ct_distance[position]);

                startActivity(i);

            }
        });

}

void updateList(final String url)
{
   getListView().post(new Runnable(){ public void run(){ updateData(url); }});
}

and then do this in gotLocation:

@Override
        public void gotLocation(Location location) {
            // TODO Auto-generated method stub
            if (location != null) {

                    //Here is the String i am trying to access
                    updateList("http://www.doamin.com/list.php?lat=" + location.getLatitude() + "&long=" + location.getLongitude());
            }
        }

You'll need to fix up any compile errors, but something like this should work for you.
