Exctracting more than one field at time from a JSon file

I was developing a simple application that exctracts some fields of a JSon that tells me in real time what weather is in that exact moment, and I have exctracted only one filed, and I was asking myself: Is it possible to extract more than on field at time?
Here is the the link from where i parse the Json:
https://fcc-weather-api.glitch.me/api/current?lat=35&lon=139
And here's my code:
public class MainActivity extends AppCompatActivity {
Button btnHit;
TextView txtJson;
ProgressDialog pd;
ArrayMap<Integer, String> arrayMap = new ArrayMap<>();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
btnHit = (Button) findViewById(R.id.btnHit);
txtJson = (TextView) findViewById(R.id.tvJsonItem);
btnHit.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
new JsonTask().execute("https://fcc-weather-api.glitch.me/api/current?lat=35&lon=139");
}
});
}
public class JsonTask extends AsyncTask<String, String, String> {
protected void onPreExecute() {
super.onPreExecute();
pd = new ProgressDialog(MainActivity.this);
pd.setMessage("Please wait");
pd.setCancelable(false);
pd.show();
}
protected String doInBackground(String... params) {
HttpURLConnection connection = null;
BufferedReader reader = null;
try {
URL url = new URL(params[0]);
connection = (HttpURLConnection) url.openConnection();
connection.connect();
InputStream stream = connection.getInputStream();
reader = new BufferedReader(new InputStreamReader(stream));
StringBuffer buffer = new StringBuffer();
String line = "";
while ((line = reader.readLine()) != null) {
buffer.append(line + "\n");
Log.d("Response: ", "> " + line);
}
return buffer.toString();
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} finally {
if (connection != null) {
connection.disconnect();
}
try {
if (reader != null) {
reader.close();
}
} catch (IOException e) {
e.printStackTrace();
}
}
return null;
}
#Override
protected void onPostExecute(String result) {
super.onPostExecute(result);
if (pd.isShowing()) {
pd.dismiss();
}
try {
JSONObject Object = new JSONObject(result);
JSONArray arr = new JSONArray(Object.getString("weather"));
for (int i = 0; i < arr.length(); i++) {
JSONObject jsonPart = arr.getJSONObject(i);
//txtJson.append("main: " + jsonPart.getString("main") + '\n');
arrayMap.put(i, jsonPart.getString("main"));
txtJson.append("main: " + arrayMap.get(i) + '\n');
}
} catch (JSONException e) {
e.printStackTrace();
//txtJson.setText(result);
}
//txtJson.setText(result);
}
}
}

If I understand correctly you want to extract other object alongwith main from the array weather
"weather": [
{
"id": 701,
"main": "Mist",
"description": "mist",
"icon": "https://cdn.glitch.com/6e8889e5-7a72-48f0-a061-863548450de5%2F50n.png?1499366021876"
}
If that is the requirement then you can use the same process like you have done just change the name of the object.
arrayMap.put(i, jsonPart.getString("description"));
or
you can use gson and convert the object in pojo class in one go. Then use the object of the pojo and access the data.
Hope it helps.

Is it possible that the array map is too little for contain about 2000 items?

In my code i had caught data from a JSON file,
I executed the program, it stopped but didn't crash.
i've tried to change json file. I found one that is Smaller than the first one and so the program works.
this JSON file is made of data o premier legue(England) and contain 3 mainly data, the name, a key and a code of the squads.
public class MainActivity extends AppCompatActivity {
private ProgressDialog caric;
private String TAG = MainActivity.class.getSimpleName();
public ArrayMap<Integer, Valori> ArrayDati = new ArrayMap<>();

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
buttonProg = (Button) findViewById(R.id.button);
textViewProg = (TextView) findViewById(R.id.textView);
buttonProg.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
new JsonCLASS().execute("https://raw.githubusercontent.com/openfootball/football.json/master/2015-16/en.1.clubs.json");
}
});
}
private class JsonCLASS extends AsyncTask<String, String, String> {
#Override

super.onPreExecute();
caric = new ProgressDialog(MainActivity.this);
caric.setMessage("Please wait");
caric.setCancelable(false);
caric.show();
}
#Override

HttpURLConnection connection = null;
BufferedReader reader = null;
try {

connection.connect();
InputStream stream = connection.getInputStream();
reader = new BufferedReader(new InputStreamReader(stream));
StringBuffer buffer = new StringBuffer();

Log.d("Response: ", "> " + line);
}
return buffer.toString();
} catch (MalformedURLException e) {

return null;
}
#Override

super.onPostExecute(result);
try {
JSONObject jsonObject = new JSONObject(result);
JSONArray Arr = new JSONArray(jsonObject.getString("clubs"));
for (int i = 0; i < Arr.length(); i++){
JSONObject jsonPart = Arr.getJSONObject(i);
ArrayDati.put(i,new Valori( jsonPart.getString("key"), jsonPart.getString("name"), jsonPart.getString("code")));
textViewProg.setText(textViewProg.getText()+"key : "+ ArrayDati.get(i).Key
+"\n"+textViewProg.getText()+"name : "+ ArrayDati.get(i).Name
+"\n"+textViewProg.getText()+"code : "+ ArrayDati.get(i).Code );
}
} catch (Exception e ){
e.printStackTrace();
}
if (caric.isShowing()) {
caric.dismiss();
}
}
}
}
And a class to pass the data
public class Valori {
String Key;
String Name;
String Code;
public Valori(String key, String name, String code) {
this.Key = key;
this.Name = name;
this.Code = code;
}
}
With this code the application stops but it doesn't close.

I don't know how you are using your AysncTask. Try this code, it's working fine for me:

How do i set an ImageView to show an image from an image url?

When i try to set the ImageView variable "profilePicture" to the bitmap from the image url, it doesn't show anything. Please help!! I am getting the image url link from my database. This is what that async task result is.

If you are seeing background white instead image. Out of memory exception by using bitmap.
You could use
Option 1
URL newurl = new URL(photo_url_str);
mIcon_val = BitmapFactory.decodeStream(newurl.openConnection() .getInputStream());
profile_photo.setImageBitmap(mIcon_val);
Picasso
Picasso.with(context).load("http://www.myegotest.com/PhotoUpload/uploads/5.png").into(profilePicture);
I would suggest to go with Piccasso. Since it will handle everything.
