three categories item list get with diffrent category_id from json data in recyclerview android

I am developing an android app in which i store data from json.
everything is working fine but i am trying to implement multilayout Recyclerview where i show first and second category list items in a box with horizontal scroll and third list which we get from Category_id from json in vertical list
i get data from server in json where category list is open with unique category id just like
http://example.com/file_path&Category_id=3
and i get json data like
json data for category
[
{
"Category_ID":"3",
"Category_name":"Camera",
"Category_image":"upload\/images\/7089-2015-07-09.png"
},
{
"Category_ID":"9",
"Category_name":"Cars",
"Category_image":"upload\/images\/7789-2015-07-09.png"
},
]
json data for category list item
category list item json data. Every category list have unique id.
[
{
"Menu_ID":"19",
"Menu_name":"Sample 6",
"Price":"380",
"Menu_image":"upload\/images\/8611-2015-02-11.jpg"
},
{
"Menu_ID":"18",
"Menu_name":"Sample 5",
"Price":"500",
"Menu_image":"upload\/images\/8119-2015-02-11.jpg"
}
]
i am using recyclerview to show category and by clicking on category item category list is open
but i dont know how to call diffrent category list item from diffrent json category_id in a same recyclerview just like this image
Code is something like
MainActivity.java
public class ActivityProductList extends AppCompatActivity {

Android: ListView from MySQL only display the last element

I'm trying to retrieve data from MySql database and put it on a ListView, everything works fine, I even put that data into textviews(dynamically) and it works fine. But when I used a ListView, only the last element was displayed, I think that means every new element is overwritten the old one, right?
What can I do to solve this? here's my code tell what's wrong??
public class MakeAppointementActivity extends AppCompatActivity {
public List<AvailabilityList> customList;
public ListView lv;
#Override
protected void onCreate(Bundle savedInstanceState) {

while( (line = reader.readLine()) != null){
sb.append(line);
}
reader.close();
iStream.close();
} catch (IOException e) {

}
return sb.toString();
}

String fromT = appointement.get("fromT");
String toT = appointement.get("toT");
String date = appointement.get("date");

}
updateListView(); // update listview when you add all data to arraylist
}
}
private void addAvailableAppoint(final String fromT, final String toT, final String date) {
customList.add(new AvailabilityList(fromT));
}
// split new function for update listview
private updateListView(){

}
});
}
}

Try this code
.....// your above code
#Override
protected void onPostExecute(List<HashMap<String, String>> result) {
customList=new ArrayList<>(); / move it to here
for (int i = 0; i < result.size(); i++) {

addAvailableAppoint(fromT,toT,date);
}
updateListView(); // update listview when you add all data to arraylist
}
}
private void addAvailableAppoint(final String fromT, final String toT, final String date) {
customList.add(new AvailabilityList(fromT));
}
// split new function for update listview
private updateListView(){
ArrayAdapter adapter=new DoctorAvailabilityAdapter(MakeAppointementActivity.this,R.layout.list_items,customList);
adapter.notifyDataSetChanged();
lv.setAdapter(adapter);

intent.putExtra("fromT", customList.get(position).getFromT());
intent.putExtra("toT", toT);
intent.putExtra("date", date);
startActivity(intent);
}
});
}
}
Hope this help

You create new ArrayList for every item customList=new ArrayList<>();
Create list only once in OnCreate for example.
Also you create new Adapter every time you add an item, adapter should also be created only once in OnCreate then you should update data with adapter.NotifyDataSetChanged()

How to add some parsed JSON objects into a custom listview?

Well, I don't know if the title is clear, so now I'll explain everything better.
I have parsed some JSON objects. After parsing, I need to show them into a custom listview.
The JSON objects are correctly parsed into string, because I have first show them into common textviews (just for a test).
Also the custom listview is working, because I have first added some values "manually" (again, just for testing it).
Here my problem:
Now I want to add the JSON objects (parsed into string) into my custom listview. I've tried every "tip and trick" I know, unsuccessfully. After two days of working, I've decided to ask you.
Before posting the code: the http request for parsing JSON objects is made with this library.
Here the code
Getprofiledata.java
public class Getprofiledata extends ActionBarActivity {
String num;
Boolean ok=true;
int i=0;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.data);
String url = "URL FOR JSON OBJECTS";
ListView listadata = (ListView) findViewById(R.id.listadata);
final List<Data> datalist = new LinkedList <Data>();
AsyncHttpClient client = new AsyncHttpClient();
client.get(url,new AsyncHttpResponseHandler() {
#Override
public void onSuccess(String response) {
ok=true;
i=1;
num = Integer.toString(i);
while(ok==true){
try {
JSONObject jsonObject = new JSONObject(response);
JSONObject object = jsonObject.getJSONObject(num);
/*********
* THESE ARE THE STRINGS I NEED TO ADD TO MY CUSTOM LISTVIEW
*********/
String record1 = object.getString("first");
String record2 = object.getString("second");
String record3 = object.getString("third");
String record4 = object.getString("fourth");
String record5 = object.getString("fiveth");
i++;
num = Integer.toString(i);
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
ok=false;
}
}
}
#Override
public void onFailure(Throwable e,String response) {
Log.d("AREQ","http GET request failed");
}
});
/*********
* HERE WE CAN ADD VALUES TO MY CUSTOM LISTVIEW
* HOW CAN I PASS THE PREVIOUS STRING IN THIS STATEMENT?
*
* THIS IS THE METHOD:
* datalist.add(new Data(record1,record2,record3,record4,record5));
*********/
//HERE THE ADAPTER FOR MY CUSTOM LISTVIEW
Getprofiledata_customadapter adapter = new Getprofiledata_customadapter(this, R.layout.data_riga, datalist);
listadata.setAdapter(adapter);
}
}
I hope I've been clear. Can you help me? I'm desperate! :(
Thanks in advance
Edit: here my Getprofiledata_customadapter.java
public class Getprofiledata_customadapter extends ArrayAdapter<Data>{
public Getprofiledata_customadapter(Context context, int textViewResourceId,
List <Data> objects) {
super(context, textViewResourceId, objects);
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) getContext()
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = inflater.inflate(R.layout.data_riga, null);
TextView firstrecord = (TextView)convertView.findViewById(R.id.tv1);
TextView secondrecord = (TextView)convertView.findViewById(R.id.tv2);
TextView thirdrecord = (TextView)convertView.findViewById(R.id.tv3);
TextView forthrecord = (TextView)convertView.findViewById(R.id.tv4);
TextView fivethrecord = (TextView)convertView.findViewById(R.id.tv5);
Data c = getItem(position);
firstrecord.setText(c.getRecord1());
secondrecord.setText(c.getRecord2());
thirdrecord.setText(c.getRecord3());
forthrecord.setText(c.getRecord4());
fivethrecord.setText(c.getRecord5());
return convertView;
}
}

Basically you just pre-create the List first. Then with that data create an adapter and set it to your ListView.
At the moment you just loop through the data without saving it at all.
It would look something like this:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.data);
mListView = (ListView) findViewById(R.id.listadata);
String url = "URL FOR JSON OBJECTS";
AsyncHttpClient client = new AsyncHttpClient();
client.get(url,new AsyncHttpResponseHandler() {
#Override
public void onSuccess(String response) {
ok=true;
i=1;
num = Integer.toString(i);
while(ok==true){
try {
JSONObject jsonObject = new JSONObject(response);
JSONObject object = jsonObject.getJSONObject(num);
/*********
* THESE ARE THE STRINGS I NEED TO ADD TO MY CUSTOM LISTVIEW
*********/
String record1 = object.getString("first");
String record2 = object.getString("second");
String record3 = object.getString("third");
String record4 = object.getString("fourth");
String record5 = object.getString("fiveth");
// Save strings to your list
mData.add(new Data(record1,record2,record3,record4,record5));
i++;
num = Integer.toString(i);
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
ok=false;
}
}
// When the data loop is over create the adapter and set it to your ListView
Getprofiledata_customadapter adapter = new Getprofiledata_customadapter(this,
R.layout.data_riga, mData);
mListView.setAdapter(adapter);
}
#Override
public void onFailure(Throwable e,String response) {
Log.d("AREQ","http GET request failed");
}
});
}

Listview is getting the value twice

I have a API which responds in JSON. When I clicked a button I am comfortably parse the JSON and implement it in the listview. The problem is When I go back to the previous activity and clicked the button once again I am getting the values repeat. i.e. previous values also, even I had called finish(); in on pause state of the listview activity. Following is my code.

Please Help.. !! I dnt know what Is I am doing wrong.
Thanks in advance.

The problem is with the "static" key word for the ArrayList
public static ArrayList<HashMap<String, String>> ModuleName = new ArrayList<HashMap<String, String>>();
static variables are initialized only when the class is loaded, that means the value will be persisted till the end of the application process.
Either remove static keyword for array list or clear the array list before you load new data.
ModuleName.clear();

populating multiple data into android listview

I am trying to learn populating data from the server to Listview.
I am new to android
MainActivity.java
public class MainActivity extends Activity {
// url to make request
private static String url = "http://URL:7002/";
private static String url1 = "http://URL:7002/XXX";
//private HashMap<Integer, String> TimeMap = new HashMap<Integer, String>();
List<Item> yourData = new ArrayList<Item>();
List<Item> yourData1 = new ArrayList<Item>();
ProgressDialog progressDialog;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//Instantiating ProgressDialog with onCreate method
progressDialog=new ProgressDialog(MainActivity.this);
new ParsingAsync().execute();
}
private class ParsingAsync extends AsyncTask<Void, Void, Void>
{
#Override
protected void onPreExecute() {
// TODO Auto-generated method stub
super.onPreExecute();
progressDialog=ProgressDialog.show(MainActivity.this, "", "Please Wait", true, false);
}
#Override
protected Void doInBackground(Void... params) {
// TODO Auto-generated method stub
// Creating JSON Parser instance
JSONObjParser jParser = new JSONObjParser();
// getting JSON string from URL
JSONArray json = jParser.getJSONFromUrl(url);
// getting JSON string from URL
JSONArray json1 = jParser.getJSONFromUrl(url1);
try {
for (int i = 0; i < json1.length(); i++) {
JSONObject c = json1.getJSONObject(i);
// Storing each json item in variable
int id = c.getInt("_id");
String TIME = c.getString("RestaurantTime");
yourData1.add(new Item(TIME));
}
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
try {
for (int i = 0; i < json.length(); i++) {
JSONObject c = json.getJSONObject(i);
// Storing each json item in variable
String NAME=c.getString("restaurantNAME");
yourData.add(new Item(NAME));
}
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;
}
#Override
protected void onPostExecute(Void result) {
// TODO Auto-generated method stub
super.onPostExecute(result);
progressDialog.dismiss();
//TextView timedisplay=(TextView) findViewById(R.id.RestaurantTimeID);
ListView yourListView = (ListView) findViewById(R.id.listViewID);
ListAdapter customAdapter = new ListAdapter(MainActivity.this, R.layout.itemlistrow, yourData);
yourListView.setAdapter(customAdapter);
// remaining code
ListAdapter.java
public class ListAdapter extends ArrayAdapter<Item> {
private List<Item> items;
public ListAdapter(Context context, int resource, List<Item> items) {
super(context, resource, items);
this.items = items;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View v = convertView;
TextView tt = null;
TextView time=null;
if (v == null) {
LayoutInflater vi;
vi = LayoutInflater.from(getContext());
v = vi.inflate(R.layout.itemlistrow, null);
tt = (TextView) v.findViewById(R.id.RestaurantNameID);
time = (TextView) v.findViewById(R.id.RestaurantTimeID);
}
Item p = items.get(position);
if (p != null) {
if (tt != null) {
tt.setText(""+p.getName());
}
if (time != null) {
time.setText(""+p.getTime());
}
}
return v;
}
}
Item.java
public class Item{
private String Name;
private String Time;
public Item(String name){
this.Name = name;
}
public String getName(){
return Name;
}
public void Time(String time){
this.Time = time;
}
public String getTime(){
return Time;
}
}
How can i resolve this
I have posted required classes above
Using List for populating the data is i am looking at
Any ideas,
Thanks.

You set TIME to yourdata1 and NAME to yourdata. The objects of yourdata1 only contains TIME and the NAME is null. The objects of yourdata only contains NAME and the TIME is null.
Please set NAME and TIME in one object and store it in one List which will be passed to ListAdapter.
I hope you can understand me.
#Override
protected Void doInBackground(Void... params) {
// TODO Auto-generated method stub
// Creating JSON Parser instance
JSONObjParser jParser = new JSONObjParser();
// getting JSON string from URL
JSONArray json = jParser.getJSONFromUrl(url);
// getting JSON string from URL
JSONArray json1 = jParser.getJSONFromUrl(url1);
// assume json's length is the same as json1's
try {
for (int i = 0; i < json1.length(); i++) {
JSONObject c = json1.getJSONObject(i);
Item item = new Item();
// Storing each json item in variable
int id = c.getInt("_id");
String TIME = c.getString("RestaurantTime");
item.setTime(TIME);
c = json.getJSONObject(i);
// Storing each json item in variable
String NAME=c.getString("restaurantNAME");
item.setName(NAME);
yourData.add(item);
}
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;
}
and
public class Item{
private String Name;
private String Time;
public String getName() {
return Name;
}
public void setName(String name) {
Name = name;
}
public String getTime() {
return Time;
}
public void setTime(String time) {
Time = time;
}
}
