Здравствуйте еще раз, это мой второй вопрос в SO. Это мой первый вопрос . Ответ, данный ребятами, действительно полезен, поэтому я попытался реализовать его. И вот моя реализация.
Создание класса JSONFunction со статическим методом, который вернет json Объект .
public class JSONFunction {
public static JSONObject getJSONfromURL(String url){
InputStream is = null;
String result = "";
JSONObject jArray = null;
//http post
try{
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(url);
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);
StringBuilder sb = new StringBuilder();
String line = null;
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());
}
try{
jArray = new JSONObject(result);
}catch(JSONException e){
Log.e("log_tag", "Error parsing data "+e.toString());
}
return jArray;
}
}
СЕЙЧАС МОЕЙ ОСНОВНОЙ ДЕЯТЕЛЬНОСТЬЮ ..
public class JsonExampleActivity extends ListActivity {
/** Called when the activity is first created. */
JSONFunction JSONfunction;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.listplaceholder);
ArrayList<HashMap<String, String>> mylist = new ArrayList<HashMap<String, String>>();
JSONObject json = JSONFunction.getJSONfromURL("https://maps.googleapis.com/maps/api/place/search/json?location=-33.8670522,151.1957362&radius=1000&types=resturants&sensor=false&key=0bBgLl42nWwl7TQHrAFpY89v2FeLlijIGTLJ1AA");
try{
JSONObject httpattributr= json.getJSONObject("html_attributions");
//JSONObject results =new JSONObject("results");
JSONArray JArray = httpattributr.getJSONArray("results");
for(int i=0;i<JArray.length();i++){
HashMap<String, String> map = new HashMap<String, String>();
JSONObject e = JArray.getJSONObject(i);
map.put("id", String.valueOf(i));
map.put("name", "" + e.getString("name"));
map.put("type", "type: " + e.getString("type"));
mylist.add(map);
}
}catch(JSONException e) {
Log.e("log_tag", "Error parsing data "+e.toString());
}
ListAdapter adapter = new SimpleAdapter(this, mylist , R.layout.main,
new String[] { "name", "type" },
new int[] { R.id.item_title, R.id.item_subtitle });
setListAdapter(adapter);
final ListView lv = getListView();
lv.setTextFilterEnabled(true);
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
@SuppressWarnings("unchecked")
HashMap<String, String> o = (HashMap<String, String>) lv.getItemAtPosition(position);
Toast.makeText(JsonExampleActivity.this, "ID '" + o.get("id") + "' was clicked.", Toast.LENGTH_SHORT).show();
}
});
}
}
Но я получаю сообщение об ошибке в logcat как
11-04 19:56:53.099: ERROR/log_tag(298): Error parsing data org.json.JSONException: JSONObject["html_attributions"] is not a JSONObject.
Любая помощь будет высоко ценится
Заранее спасибо.
Результат в формате JSON выглядит как
