Store value to arraylist from json data and populate view holder

Question

I am making an application in which I am receiving some JSON data from url as shown in this Image. Basically every date array has 5 objects in it and I am using this piece of code to get the session from and session to values from each date array

 JSONObject jsonObject = new JSONObject(response);
 JSONObject dataObj = jsonObject.getJSONObject("data");
      Iterator<String> iter = dataObj.keys();
      while (iter.hasNext()) {
              key = iter.next();
              JSONArray datesArray = dataObj.getJSONArray(key);
              sessionsfrom = new ArrayList<String>();

              JSONObject datesObjectt = datesArray.getJSONObject(4);

              for (int i = 0; i < datesArray.length(); i++) {
                  JSONObject datesObject = datesArray.getJSONObject(i);
                  sessionsfrom.add(datesObject.getString("session_from") + " - " +datesObject.getString("session_to") );
                  mBaseRecyclerAdapter.setItems(sessionsfrom);
                                    }

In the last line I am storing all the session from and session to values in arraylist and put in adapter of recycler view. These sessions are creating time slots in the app as shown in this Image Now what I want is that I have to save bookingFound value from json to somewhere with session from and session to value i.e. it doesnot show in app but in the background of each slot, every value of bookingFoung must be stored so that when populating viewholder I can check which bookingFound slots return true and which return false so that I can change the color of slots to grey if bookingFound true

To populate view holder I have the following piece of code

   private BaseRecyclerAdapter<String, CourtDetailsTimeViewHolder> mBaseRecyclerAdapter = new BaseRecyclerAdapter<String, CourtDetailsTimeViewHolder>(CourtDetailsTimeViewHolder.class, R.layout.item_court_details_availability_time) {

    @Override
    protected void populateViewHolder(CourtDetailsTimeViewHolder viewHolder, String model, int position) {
       // SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(getContext());
        //String name = preferences.getString("slotfound", "");
        viewHolder.mCheckBox.setOnCheckedChangeListener(null);
        viewHolder.mCheckBox.setText(model);
        viewHolder.mCheckBox.setChecked(getChecked(model));
        /*for (int i = 0; i < bookingcheck.size(); i++) {
            if (bookingcheck.get(i).contains("true")) {
                viewHolder.mCheckBox.setEnabled(false);
                viewHolder.mCheckBox.setBackgroundResource(R.drawable.slctr_bg_cb_challenges_details_disable);
            } else {
                viewHolder.mCheckBox.setEnabled(true);
                viewHolder.mCheckBox.setBackgroundResource(R.drawable.slctr_bg_cb_challenges_details);
            }
        }*/

    }
};

In this code, the commented part is what I tried but it doesnot worked. I put bookingFound values in bookingcheck arraylist and then checked if it contains true then slots disabled otherwise enabled but it doesnot work... Please Help

Conclusion

1- store bookingFound json value just like session from and session to values

2- use that value to enable or disable slots on the application

but my question is not about that :( – Aarks Sep 08 '18 at 10:25 — Aarks, Sep 08 '18 at 10:25

For a quick fix

use

datesObject.getString("session_from") + " - " +datesObject.getString("session_to")+"$"+datesObject.get("bookingFound").getAsBoolean()

While Displaying Sessions use

String Session = "02:00 AM - 02:30 AM$true";
String[] separated = currentString.split("$");
separated[0]; // this will contain "02:00 AM - 02:30 AM"
separated[1]; // this will contain "true"

for (int i = 0; i < bookingcheck.size(); i++) {
            if (bookingcheck.get(i).contains("true")) {
                viewHolder.mCheckBox.setEnabled(false);
                viewHolder.mCheckBox.setBackgroundResource(R.drawable.slctr_bg_cb_challenges_details_disable);
            } else {
                viewHolder.mCheckBox.setEnabled(true);
                viewHolder.mCheckBox.setBackgroundResource(R.drawable.slctr_bg_cb_challenges_details);
            }
        }

you have to change some code. fist, create a custom object for the session to enhance the performance and the design of code

public class SessionModel {

    String sessionFrom;
    String sessionTo;
    boolean sessionFound;


    public SessionModel(String sessionFrom, String sessionTo, boolean sessionFound) {
        this.sessionFrom = sessionFrom;
        this.sessionTo = sessionTo;
        this.sessionFound = sessionFound;
    }


    public String getSessionFrom() {
        return sessionFrom;
    }

    public void setSessionFrom(String sessionFrom) {
        this.sessionFrom = sessionFrom;
    }

    public String getSessionTo() {
        return sessionTo;
    }

    public void setSessionTo(String sessionTo) {
        this.sessionTo = sessionTo;
    }

    public boolean isSessionFound() {
        return sessionFound;
    }

    public void setSessionFound(boolean sessionFound) {
        this.sessionFound = sessionFound;
    }
}

then create an arraylist of this object and use this arraylist in adapter "after for loop finish"

JSONObject jsonObject = new JSONObject(response);
    JSONObject dataObj = jsonObject.getJSONObject("data");
    Iterator<String> iter = dataObj.keys();
    while (iter.hasNext()) {
    key = iter.next();
    JSONArray datesArray = dataObj.getJSONArray(key);
    sessionsfrom = new ArrayList<SessionModel>();

    JSONObject datesObjectt = datesArray.getJSONObject(4);

    for (int i = 0; i < datesArray.length(); i++) {
    JSONObject datesObject = datesArray.getJSONObject(i);
    sessionsfrom.add(SessionModel(datesObject.getString("session_from"), datesObject.getString("session_to"), datesObject.getboolean("bookinFound")));
    }
    mBaseRecyclerAdapter.setItems(sessionsfrom);

in in your adapter

private BaseRecyclerAdapter<String, CourtDetailsTimeViewHolder> mBaseRecyclerAdapter = new BaseRecyclerAdapter<String, CourtDetailsTimeViewHolder>(CourtDetailsTimeViewHolder.class, R.layout.item_court_details_availability_time) {

    @Override
    protected void populateViewHolder(CourtDetailsTimeViewHolder viewHolder, SessionModel model, int position) {

        viewHolder.mCheckBox.setOnCheckedChangeListener(null);
        viewHolder.mCheckBox.setText(model.getgetSessionFrom+"-"+model.getSessionTo);
        viewHolder.mCheckBox.setChecked(getChecked(model));

            if (model.get(i).isSessionFound()) {
                viewHolder.mCheckBox.setEnabled(false);
                viewHolder.mCheckBox.setBackgroundResource(R.drawable.slctr_bg_cb_challenges_details_disable);
            } else {
                viewHolder.mCheckBox.setEnabled(true);
                viewHolder.mCheckBox.setBackgroundResource(R.drawable.slctr_bg_cb_challenges_details);
            }


    }
};

after changing to seesionsfrom = ArrayList then on this line "sessionsfrom.add(datesObject.getString("session_from"), datesObject.getString("session_to"), datesObject.getboolean("bookinFound"));" — Aarks, Sep 08 '18 at 11:09
it saying model.sessionModel in arraylist cannot be applied to java.lang.string — Aarks, Sep 08 '18 at 11:09
Change the (String sessionsfrom) to (SessionModel sessionfrom) — Momen Zaqout, Sep 08 '18 at 11:19
sessiosnfrom was already an arraylist. After you said to make model then following changes are done. i.e. ArrayList sessionsfrom = new ArrayList(); — Aarks, Sep 08 '18 at 11:22
setItems (java.util.List) in BaseRecyclerAdapter cannot be applied to (java.util.ArrayList) — Aarks, Sep 08 '18 at 11:41
now its saying this on this line " mBaseRecyclerAdapter.setItems(sessionsfrom);" — Aarks, Sep 08 '18 at 11:41
Good, I edited the code and remove redundant for loop. Please edit the code to solve last problem — Momen Zaqout, Sep 08 '18 at 11:46
