I'm trying to parse Foursquare places into android application and i got success as i can view the JSON data in Logcat but listview is not showing any data. Here is the code:
public class FoursquarePlacesActivity extends ListActivity { > > private ProgressDialog dialog; > private static final String foursquareClientid="Clientid"; > private static final String foursquareClientsecret="clientsecret"; > > private static String > url="https://api.foursquare.com/v2/venues/explore?ll=24.58,73.68&client_id=" > +foursquareClientid + "&client_secret=" +foursquareClientsecret; > > //JSON Nodes Name that Foursquare will throw > > private static final String GROUPS="groups"; > private static final String NAME_TAG = "name"; > > ArrayList<HashMap<String,String>> venueList; > > > > @Override > public void onCreate(Bundle savedInstanceState){ > super.onCreate(savedInstanceState); > setContentView(R.layout.main); > > venueList=new ArrayList<HashMap<String,String>>(); > > new getPlaces().execute(); > > } > > //AsyncTask starts here > public class getPlaces extends AsyncTask<String, String, String>{ > > > @Override > protected void onPreExecute(){ > super.onPreExecute(); > dialog=new ProgressDialog(FoursquarePlacesActivity.this); > dialog.setMessage("Please wait"); > dialog.setIndeterminate(false); > dialog.setCancelable(false); > dialog.show(); > } > > @Override > protected String doInBackground(String... args) { > // TODO Auto-generated method stub > > List<NameValuePair> params=new > ArrayList<NameValuePair>(); > > JSONObject > json=JSONParser.makeHttpRequest(url,"GET",params); > JSONArray groups= null; > Log.d("Inbox JSON:", json.toString()); > > try{ > groups=json.getJSONArray(GROUPS); > > //looping all the objects of Groups > for(int i=0;i<groups.length();i++){ > JSONObject > group=(JSONObject)groups.get(i); > //Editing part (may be incorrect > JSONArray > items=(JSONArray)group.getJSONArray("items"); > > for (int j=0;j<items.length();j++){ > JSONObject > item=(JSONObject)items.get(j); > //Editing part end > //Store json item in variable > String > name=item.getString(NAME_TAG); > HashMap<String,String>map=new > HashMap<String, String>(); > > map.put(NAME_TAG, name); > > venueList.add(map); > } > > > } > > > } catch (JSONException e){ > e.printStackTrace(); > } > > return null; > } > > protected void onPostExecute(String file_url){ > dialog.dismiss(); > > runOnUiThread(new Runnable(){ > public void run(){ > ListAdapter adapter=new > SimpleAdapter(FoursquarePlacesActivity.this, venueList,R.layout.list_item,new > String[]{ NAME_TAG },new int[] { R.id.name }); > > setListAdapter(adapter); > > ListView lv = getListView(); > > // Launching new screen on > Selecting Single ListItem > lv.setOnItemClickListener(new > OnItemClickListener(){ > > > @Override > public void > onItemClick(AdapterView<?> parent, View view, > int position, long > id) { > > String > name=((TextView)view.findViewById(R.id.name)).getText().toString(); > } > }); > > } > }); > } > > > > } > > > } > > -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
