Inilah solusinya:
Saya pada dasarnya membuat berdiri sendiri dan menguraikan JSON Anda seperti ini:
Pertama : Ini adalah metode yang saya gunakan untuk mengurai JSON:
public String loadJSON(String someURL) {
String json = null;
HttpClient mHttpClient = new DefaultHttpClient();
HttpGet mHttpGet = new HttpGet(someURL);
try {
HttpResponse mHttpResponse = mHttpClient.execute(mHttpGet);
StatusLine statusline = mHttpResponse.getStatusLine();
int statusCode = statusline.getStatusCode();
if (statusCode != 200) {
return null;
}
InputStream jsonStream = mHttpResponse.getEntity().getContent();
BufferedReader reader = new BufferedReader(new InputStreamReader(
jsonStream));
StringBuilder builder = new StringBuilder();
String line;
while ((line = reader.readLine()) != null) {
builder.append(line);
}
json = builder.toString();
} catch (IOException ex) {
ex.printStackTrace();
return null;
}
mHttpClient.getConnectionManager().shutdown();
return json;
}
Kedua : Menggunakan Tugas Async untuk mengunduh data:
public class BackTask extends AsyncTask<Void, Void, Void> {
String url;
public BackTask(String URL) {
super();
this.url = URL;
}
@Override
protected Void doInBackground(Void... params) {
getData(url);
return null;
}
}
Ketiga: Metode untuk mengambil data dan menguraikannya. Saya telah memberikan beberapa komentar untuk bagian ini karena ini agak panjang dari biasanya.
public void getData(String URL) {
try {
JSONObject mainJsonObject = new JSONObject(loadJSON(URL));
// Log.d("JSON Data : ", mainJsonObject.toString());
String Status = mainJsonObject.getString("status");
Log.d("JSON Status : ", Status + "\n" + "---------------------");
JSONArray mainArray = mainJsonObject.getJSONArray("results");
// Log.d("JSON Array : ", mainArray.toString());
for (int i = 0; i < mainArray.length(); i++) {
JSONObject insideJsonObject = mainArray.getJSONObject(i);
if (insideJsonObject != null) {
String address_components = insideJsonObject
.getString("address_components");
// Log.d("Inside JSON Array : ", address_components);
JSONArray addressJSON = insideJsonObject
.getJSONArray("address_components");
// Log.d("Inside JSON ADDress : ", addressJSON.toString());
String formatted_address = insideJsonObject
.getString("formatted_address");
Log.d("Inside JSON formatted_address : ", formatted_address
+ "\n" + "-----------");
for (int ji = 0; ji < mainArray.length(); ji++) {
JSONObject geoMetryJO = mainArray.getJSONObject(ji);
if (geoMetryJO != null) {
JSONObject geometry = geoMetryJO
.getJSONObject("geometry");
// Log.d("Inside JSON geometry : ",
// geometry.toString()+"\n"+"----------");
String location_type = geometry
.getString("location_type");
Log.d("Inside JSON location_type : ", location_type
+ "\n" + "------------");
JSONObject locationJSONObject = geometry
.getJSONObject("location");
String Latitude = locationJSONObject
.getString("lat");
Log.d("Inside JSON Latitude : ", Latitude + "\n"
+ "--------------");
String Longitude = locationJSONObject
.getString("lng");
Log.d("Inside JSON Longitude : ", Longitude + "\n"
+ "------------");
JSONObject viewportJSONObject = geometry
.getJSONObject("viewport");
// Log.d("Inside JSON viewportJSONObject : ",
// viewportJSONObject.toString()+"\n"+"------------");
JSONObject northeastJSONObject = viewportJSONObject
.getJSONObject("northeast");
String Lat = northeastJSONObject.getString("lat");
Log.d("Inside JSON Lat : ", Lat + "\n"
+ "------------");
String Lon = northeastJSONObject.getString("lng");
Log.d("Inside JSON Lon : ", Lon + "\n"
+ "------------");
JSONObject southwestJSONObject = viewportJSONObject
.getJSONObject("southwest");
String south_Lat = southwestJSONObject
.getString("lat");
Log.d("Inside JSON south_Lat : ", south_Lat + "\n"
+ "------------");
String south_Lon = southwestJSONObject
.getString("lng");
Log.d("Inside JSON south_Lon : ", south_Lon + "\n"
+ "------------");
}
}
for (int k = 0; k < addressJSON.length(); k++) {
JSONObject addressJSONObject = addressJSON
.getJSONObject(k);
if (addressJSONObject != null) {
String long_name = addressJSONObject
.getString("long_name");
Log.d("Inside JSON LongName : ", long_name);
String short_name = addressJSONObject
.getString("short_name");
Log.d("Inside JSON ShortName : ", short_name);
JSONArray addressJSONArray = addressJSONObject
.getJSONArray("types");
Log.d("Inside JSON JSONADD : ",
addressJSONArray.toString() + "\n"
+ "-------------");
}
}
JSONArray insideJsonArray = insideJsonObject
.getJSONArray("types");
Log.d("Inside JSON Types : ", insideJsonArray.toString());
String street = insideJsonObject.getString("types");
Log.d("Inside JSON Street : ", street);
}
}
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
Setelah mendapatkan semua data, Anda dapat menggunakannya sesuka Anda karena sebagian besar dalam format string. Anda cukup menyalin dan menempelkan metode ini dan metode ini akan berjalan dengan baik.
Keempat : Pada metode onCreate(), jalankan saja tugas seperti ini:
public static final String URL = "http://maps.googleapis.com/maps/api/geocode/json?address=1600+Amphitheatre+Parkway,+Mountain+View,+CA";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
new BackTask(URL).execute();
}
Ini adalah solusi lengkap untuk pertanyaan ini. Beri tahu saya jika ada pertanyaan mengenai hal ini. Semoga ini bisa membantu..Semoga Sukses.. :)

address_componentsAnda harus mendapatkan arrayresults, lalu dari elemen pertama (atau apa pun), dan kemudian Anda bisa membacakanaddress_components. - person Philipp Gayret schedule 14.06.2014
