公共LocationResult

Question

外訪問字符串信息我有一個腳本如下從LocationResult獲取URL在httppost使用

public class List extends ListActivity { 

    int ct_id;

      } 
     } 
     catch(JSONException e1){ 
      Toast.makeText(getBaseContext(), "No Addresses 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(), TimsListMore.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); 

      } 
     }); 
    } 

    protected boolean isKeyInstalled(Context context) { 
      // the packagename of the 'key' app 
      String proPackage = "XXXXXXXXXXXXXXXXXXXX"; 

      // get the package manager 
      final PackageManager pm = context.getPackageManager(); 

      // get a list of installed packages 
      List<PackageInfo> list = pm.getInstalledPackages(PackageManager.GET_DISABLED_COMPONENTS); 

      // let's iterate through the list 
      Iterator<PackageInfo> i = list.iterator(); 
      while(i.hasNext()) { 
      PackageInfo p = i.next(); 
      // check if proPackage is in the list AND whether that package is signed 
      // with the same signature as THIS package 
      if((p.packageName.equals(proPackage)) && 
       (pm.checkSignatures(context.getPackageName(), p.packageName) == PackageManager.SIGNATURE_MATCH)) 
       return true; 
      } 
      return false; 
     } 

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

    public LocationResult locationResult = new LocationResult() { 


     public void gotLocation(Location location) { 
      // TODO Auto-generated method stub 
      if (location != null) { 
       String infourl = "http://www.somedomain.com/list.php?lat=" + location.getLatitude() + "&long=" + location.getLongitude(); 

      } 
     } 
    }; 
} 

所以這

String infourl = "http://www.somedomain.com/list.php?lat=" + location.getLatitude() + "&long=" + location.getLongitude(); 

需要進入

String result = null; 
     InputStream is = null; 
     StringBuilder sb = null; 
     //http post 
     try{ 
      HttpClient httpclient = new DefaultHttpClient(); 
      HttpPost httppost = new HttpPost("" + infourl + ""); 
      //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()); 
     } 

我認爲這不會是一件難事。

Answer 1

我的建議是嘗試使用公共字符串...希望這有助於。

Answer 2

繼前面的問題：

public LocationResult locationResult = new LocationResult() { 
    String latitude = null; 
    String longitude = null; 

    public void gotLocation(Location location) { 
    if (location != null) { 
     latitude = location.getLatitude() + ""; 
     longitude = location.getLongitude() + ""; 
    } 
    } 

    public String getLatitude() { 
    return latitude; 
    } 
    public String getLongitude() { 
    return longitude; 
    } 
} 

你可以使用它作爲

String location = new String (locationResult.getLatitude() + " " + locationResult.getLongitude()); 

在活動的任何地方。當然，這是非常粗糙的，甚至根本不檢查是否有有效的位置，但它給了你解決這個問題的想法。我相信你真正想要的是與你所問的相反：如果你需要lat和long值發送一個http文章，那麼我會在gotLocation函數中做文章。這樣，你確定你不會發送空值到帖子。創建方法

public void postURL (String urlString) { 
    if (urlString == null) return; 
    HttpPost httppost = new HttpPost(urlString); 
    // whatever else code you have to handle responses, etc. 
} 

，並從whithin在這似乎gotLocation()作爲

TimsList.this.postURL ("http://mytimmies.myfunhouse.net/app_main_list.php?lat=" + 
    location.getLatitude() + "&long=" + location.getLongitude());
