Here you can use following classes to parse your Response:
Create Two classes:
1. DepartmentAndCategory
2. ProductsAndDeals
//DepartmentAndCategory class
public class DepartmentAndCategory {

Have spinner dependent on item selected on other spinner

I want to show the number of days depending on the month chosen. Like if month chosen is January show dates till 31 but if it is february show until 29. I saw and tried some solutions but they didn't work out for me.
Here's my SignUpActivity class:
public class SignupActivity extends AppCompatActivity {
EditText first;
EditText last;
TextView birth;
Spinner month;
Spinner date;
Spinner year;
EditText email;
EditText phone;
EditText username;
EditText password;
Button done;
String[] dayOptions = new String[]{
"1", "2", "3", "4", "5", "6", "7", "8", "9", "10", "11", "12", "13", "14", "15", "16", "17", "18", "19", "20", "21", "22", "23", "24", "25", "26", "27", "28", "29", "30", "31"
};
String[] dayOptions2 = new String[]{
"1", "2", "3", "4", "5", "6", "7", "8", "9", "10", "11", "12", "13", "14", "15", "16", "17", "18", "19", "20", "21", "22", "23", "24", "25", "26", "27", "28", "29", "30"
};
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_signup);
first = (EditText) findViewById(R.id.firstName);
last = (EditText) findViewById(R.id.lastName);
birth = (TextView) findViewById(R.id.birthText);
month = (Spinner) findViewById(R.id.birthMonth);
date = (Spinner) findViewById(R.id.birthDate);
year = (Spinner) findViewById(R.id.birthYear);
email = (EditText) findViewById(R.id.email);
phone = (EditText) findViewById(R.id.phoneNumber);
username = (EditText) findViewById(R.id.usernameEdit);
password = (EditText) findViewById(R.id.passwordEdit);
done = (Button) findViewById(R.id.done);
// month dropdown
final Spinner monthDrop = (Spinner) findViewById(R.id.birthMonth);
String[] monthOptions = new String[]{
"January", "February", "March", "April", "June", "July", "August", "September", "October", "November", "December"
};
ArrayAdapter<String> monthAdapter = new ArrayAdapter<>(this, android.R.layout.simple_spinner_dropdown_item, monthOptions);
monthDrop.setAdapter(monthAdapter);
// days dropdown
Spinner dateDrop = (Spinner) findViewById(R.id.birthDate);
String[] dayOptions = new String[]{
"1", "2", "3", "4", "5", "6", "7", "8", "9", "10", "11", "12", "13", "14", "15", "16", "17", "18", "19", "20", "21", "22", "23", "24", "25", "26", "27", "28", "29", "30", "31"

dateDrop.setAdapter(adapter);
// year dropdown
Spinner yearDrop = (Spinner) findViewById(R.id.birthYear);
String[] yearOptions = new String[]{
"1990", "1991", "1992", "1993", "1994", "1995", "1996", "1997", "1998", "1999", "2000", "2001", "20012", "2003", "2004", "2005", "2006"
};
ArrayAdapter<String> yearAdapter = new ArrayAdapter<>(this, android.R.layout.simple_spinner_dropdown_item, yearOptions);
yearDrop.setAdapter(yearAdapter);
// CharSequence[] dateOptions = new CharSequence[] {

done.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (first.getText().toString().equals("") || last.getText().toString().equals("") ||

username.getText().toString().equals("") || password.getText().toString().equals("") || first.getText().toString().startsWith(" ") ||
last.getText().toString().startsWith(" ") || email.getText().toString().startsWith(" ") || phone.getText().toString().startsWith(" ") ||
username.getText().toString().startsWith(" ") || password.getText().toString().startsWith(" ")) {
Toast.makeText(getApplicationContext(), "Please fill all blanks", Toast.LENGTH_SHORT).show();
} else {
Intent intent = new Intent(SignupActivity.this, MainActivity.class);
startActivity(intent);
Toast.makeText(getApplicationContext(), "You have been signed up as " + first.getText().toString() + " " + last.getText().toString() + " (" + username.getText().toString() + ")", Toast.LENGTH_SHORT).show();
}
}
});
}
Any help would be appreciated! Thanks in advance!
UPDATE: I tried #siva35's answer but then the date dropdown options are all gone. My code is:
month.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parentView, View selectedItemView, int position, long id) {
// int intPosition = position;
if(position == 0 || position == 2 || position == 4 || position == 5 || position == 7 || position == 9 ||position == 11) {
// Spinner date = (Spinner) findViewById(R.id.birthDate);
String[] dayOptions = new String[]{
"1", "2", "3", "4", "5", "6", "7", "8", "9", "10", "11", "12", "13", "14", "15", "16", "17", "18", "19", "20", "21", "22", "23", "24", "25", "26", "27", "28", "29", "30", "31"
};
ArrayAdapter<String> adapter = new ArrayAdapter<>(getApplication(), android.R.layout.simple_spinner_dropdown_item, dayOptions);
date.setAdapter(adapter);
} else if(position == 3 || position == 5 || position == 6 || position == 9 || position == 11 ) {
String[] dayOptions = new String[]{
"1", "2", "3", "4", "5", "6", "7", "8", "9", "10", "11", "12", "13", "14", "15", "16", "17", "18", "19", "20", "21", "22", "23", "24", "25", "26", "27", "28", "29", "30"
};
ArrayAdapter<String> adapter = new ArrayAdapter<>(getApplication(), android.R.layout.simple_spinner_dropdown_item, dayOptions);
date.setAdapter(adapter);
} else if(position == 1) {
String[] dayOptions = new String[]{
"1", "2", "3", "4", "5", "6", "7", "8", "9", "10", "11", "12", "13", "14", "15", "16", "17", "18", "19", "20", "21", "22", "23", "24", "25", "26", "27", "28"
};
ArrayAdapter<String> adapter = new ArrayAdapter<>(getApplication(), android.R.layout.simple_spinner_dropdown_item, dayOptions);
date.setAdapter(adapter);
} else {
Toast.makeText(getApplicationContext(), "Not working", Toast.LENGTH_LONG).show();
}
}
#Override
public void onNothingSelected(AdapterView<?> parentView) {
Toast.makeText(getApplicationContext(), "Please select something", Toast.LENGTH_LONG).show();
}
});

use OnItemSelectedListener() method.
month.setOnItemSelectedListener(new OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parentView, View selectedItemView, int position, long id) {
// your code here to display date options
}
#Override
public void onNothingSelected(AdapterView<?> parentView) {
// your code here
}
})
;

Thanks #siva35 for your answer! I got an answer to my own question. My code for it is:
month.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view,
int pos, long id) {
List<String> s = Arrays.asList(getResources().getStringArray(R.array.item_day));
if (pos == 0 || pos == 2 || pos == 4 || pos == 8 || pos == 9
|| pos == 11) {
ArrayAdapter<String> dayadapter = new ArrayAdapter<String>(SignupActivity.this, android.R.layout.simple_spinner_item,s);
date.setAdapter(dayadapter);
} else if (pos == 1) {
s = s.subList(0,28);
ArrayAdapter<String> dayadapter = new ArrayAdapter<String>(SignupActivity.this, android.R.layout.simple_spinner_item,s);
date.setAdapter(dayadapter);
} else {
s = s.subList(0,30);
ArrayAdapter<String> dayadapter = new ArrayAdapter<String>(SignupActivity.this, android.R.layout.simple_spinner_item,s);
date.setAdapter(dayadapter);
}
}
#Override
public void onNothingSelected(AdapterView<?> arg0) {
Toast.makeText(getApplicationContext(), "Please select something", Toast.LENGTH_SHORT).show();
}
});

How to parse Array of Objects in Android

I am parsing the following json response but there is some problem in parsing,the code I'm trying is not parsing and I am not getting any exception or response.
The code that I had applied to parse it is:
ArrayList<Model_BarcodeDetail> DownloadBarcode(String api_token) {
ArrayList<Model_BarcodeDetail> barcodeList = new ArrayList<Model_BarcodeDetail>();
HttpClient httpClient = new DefaultHttpClient();
HttpPost postRequest = new HttpPost(Utility.BASE_URL

+ "&return=json");
String url = Utility.BASE_URL
+ "?q=webservice/barcode_list&token=" + api_token +"&page="+"1"
+ "&return=json";
System.out.println("======url::"+url);
String result = "";
ArrayList<Model_BarcodeDetail> group_list = null;
ArrayList<Model_BarcodeList_Child> child_list = null;
try {
group_list = new ArrayList<Model_BarcodeDetail>();
ResponseHandler<String> responseHandler = new BasicResponseHandler();
result = httpClient.execute(postRequest, responseHandler);
JSONObject root = new JSONObject(result);
JSONObject obj = root.getJSONObject("");
System.out.println("====objjjj: "+obj.toString());
JSONArray arraylist=obj.names();
for (int i = 0; i < arraylist.length(); i++) {
child_list = new ArrayList<Model_BarcodeList_Child>();
JSONObject jsonObj = arraylist.getJSONObject(i);
System.out.println("---json" + jsonObj);
Model_BarcodeDetail data = new Model_BarcodeDetail();
data.setReference((jsonObj.getString("ref")));
System.out.println("======refinprsing--"+data.getReference());
// data.setName((jsonObj.getString("name")));
// data.setDescription((jsonObj.getString("desc")));
// data.setPrice((jsonObj.getString("price")));
// data.setTotal(data.getPrice().trim());
// data.setFixedTotal(data.getPrice().trim());
JSONArray obj2 = jsonObj.getJSONArray("barcodes");
for (int j = 0; j < obj2.length(); j++) {
JSONObject json = obj2.getJSONObject(j);
System.out.println("---json" + json);
Model_BarcodeList_Child data2 = new Model_BarcodeList_Child();
data2.setBarcode((json.getString("barcode")));
System.out.println("=======barcodeinparsing: "+data2.getBarcode());
data2.setColor((json.getString("color")));
data2.setSize((json.getString("size")));
data2.setPrice(json.getString("price"));
data2.setStock(json.getString("stock"));
data2.setAlis_code(json.getString("alias_code"));
child_list.add(data2);
}
data.setChildItems(child_list);

}
}
} catch (Exception e) {

According to your json Response do parsing like below
JSONObject root = new JSONObject(result);
JSONArray array = root.getJSONArray("array");
String boolean = root.getString("boolean");
String null= root.getString("null");
String number= root.getString("number");
String string = root.getString("string");
JSONArray array_1 = root.getJSONArray("object");
first check your result is not getting null ? please check log.

Based on the json provided change this:
JSONObject root = new JSONObject(result);
JSONObject obj = root.getJSONObject("");
System.out.println("====objjjj: "+obj.toString());
JSONArray arraylist=obj.names();
To this:
JSONObject root = new JSONObject(result);
JSONArray arraylist= root.names();
for (int i = 0; i < arraylist.length(); i++) {
child_list = new ArrayList<Model_BarcodeList_Child>();
JSONObject jsonObj = root.getJSONObject(arrayList.getString(i));
I would also add a check to see if the name equals pager, in that case continue;

Here is solution
JSONObject root = new JSONObject(result);
if(root != null){
Iterator iter = root.keys();
while (iter.hasNext()){
try {
String key = (String) iter.next();
JSONObject itemObject = root.getJSONObject(key);
} catch (JSONException e) {
}
}
}

Thank you very much for your help.

Replace
JSONObject discoverObj = (JSONObject) discoverArray.opt(i);
with
JSONObject discoverObj = discoverArray.getJSONObject(i);
Review the below code

JSONArray discoverArray = (JSONArray) response.optJSONArray("users");
ArrayList<Discover> discovers = new ArrayList<Discover>();

discover.setAge(discoverObj.optString("age"));
discover.setMutualFriend(discoverObj.optInt("mutualFriend"));
