Multiple check item send params

Multiple check item send params - android

I have set switch box in adapter when switch box is enable then open custom check box list item. I have select check box item multiple. This switch box design when select spinner item and then open fragment page. When select multiple check box item and send JSON param like this:
"attendees": [
{
"id": "1",
"person": "xza"
},
{
"id": "2",
"person": "cfd"
}
]
And send button applying in activity. Spinner and save button design in activity and select item design in fragment.
I have make model class like:
public class MeetingModel {
public String date;
public String time;
public boolean reminder;
public boolean assignTOther;
public boolean contactTo;
public boolean attendeesTo;
public String remark;
private MeetingReminder meetingReminder;
private int assignid;
private int contactid;
private List<Assigne> attendees = null;
private int attendeesid;
private String location;
private String purpose;
private String clientType;
private String id;
private String logSubType;
public String getDate() {
return date;
}
public void setDate(String date) {
this.date = date;
}
public String getTime() {
return time;
}
public void setTime(String time) {
this.time = time;
}
public boolean isReminder() {
return reminder;
}
public void setReminder(boolean reminder) {
this.reminder = reminder;
}
public boolean isAssignTOther() {
return assignTOther;
}
public void setAssignTOther(boolean assignTOther) {
this.assignTOther = assignTOther;
}
public boolean isContactTo() {
return contactTo;
}
public void setContactTo(boolean contactTo) {
this.contactTo = contactTo;
}
public boolean isAttendeesTo() {
return attendeesTo;
}
public void setAttendeesTo(boolean attendeesTo) {
this.attendeesTo = attendeesTo;
}
public String getRemark() {
return remark;
}
public void setRemark(String remark) {
this.remark = remark;
}
public MeetingReminder getMeetingReminder() {
return meetingReminder;
}
public void setMeetingReminder(MeetingReminder meetingReminder) {
this.meetingReminder = meetingReminder;
}
public int getAssignid() {
return assignid;
}
public void setAssignid(int assignid) {
this.assignid = assignid;
}
public int getContactid() {
return contactid;
}
public void setContactid(int contactid) {
this.contactid = contactid;
}
public void setMeetingReminder(String date, String time) {
MeetingReminder meetingReminder = new MeetingReminder();
meetingReminder.setDate(date);
meetingReminder.setTime(time);
setMeetingReminder(meetingReminder);
}
public String getLocation() {
return location;
}
public void setLocation(String location) {
this.location = location;
}
public String getPurpose() {
return purpose;
}
public void setPurpose(String purpose) {
this.purpose = purpose;
}
public String getClientType() {
return clientType;
}
public void setClientType(String clientType) {
this.clientType = clientType;
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getLogSubType() {
return logSubType;
}
public void setLogSubType(String logSubType) {
this.logSubType = logSubType;
}
public List<Assigne> getAttendees() {
return attendees;
}
public void setAttendees(List<Assigne> attendees) {
this.attendees = attendees;
}
public JsonArray getCheckedItems(){
List<Assigne> tmpList=new ArrayList<>();
List<Assigne> attendees = new ArrayList<>();
JsonArray jsonArray = new JsonArray();
for(Assigne attendee:attendees){
if(attendee.isHeaderSelected()){
tmpList.add(attendee);
attendee.setHeaderSelected(true);
JsonObject obj = new JsonObject();
obj.addProperty("id", attendee.getId());
obj.addProperty("name", attendee.getName());
jsonArray.add(obj);
}
}
return jsonArray;
}
}
I expect the output is:
"attendees":[{"id":"1","person":"fff"},{"id":"2","person":"dfdf"}]
But the actual output is:
"attendees": []

My intention is to get the JSON Array item and display title,price,pic,detail_url from it. I found out how to display it one at a time so far, but couldn't find how to iterate the JSON object so that I can display the data in a listview. Please help, I am new to this and I've been stuck for quite awhile now. If you want to see my interface, retrofit instance etc just let me know.

private void taobaoSearch(){
TaobaoInterface retrofitInterface = RetrofitInstance.getRetrofitInstanceTaobao().create(TaobaoInterface.class);

public void onResponse(Call<TaobaoModel> call, Response<TaobaoModel> response) {
List<Result> retro=response.body().getitems();
generateDataList(retro);
}
#Override
public void onFailure(Call<TaobaoModel> call, Throwable t) {
System.out.println("FAILED");
System.out.println(call);
t.printStackTrace();

RecyclerView to Firebase database

I actually want cardView in my RecyclerView to retrieve data from firebase but it returns error. Please do help me to attach my RecyclerView to firebase and retrieve data from it.
Thanking you in advance.
Here is the mainActivity.java
mbloglist = findViewById(R.id.rv1);
RecyclerView.LayoutManager layoutManager = new LinearLayoutManager(this);
productAdapter adapter = new productAdapter(this);
mbloglist.setLayoutManager(layoutManager);
mbloglist.setAdapter(adapter);
Toast.makeText(getApplicationContext(),"Layout starting",Toast.LENGTH_SHORT).show();
database1 = FirebaseDatabase.getInstance();
myRef = database1.getReference("Users");
Toast.makeText(getApplicationContext(),"Database Done",Toast.LENGTH_SHORT).show();
myRef.addValueEventListener(new ValueEventListener() {
#Override
public void onDataChange(DataSnapshot dataSnapshot) {
Log.e("pppp","onDataChange"+dataSnapshot.toString());
Toast.makeText(getApplicationContext(),"Done",Toast.LENGTH_SHORT).show();
for(DataSnapshot child : dataSnapshot.getChildren()){
ModelClass modelClass = child.getValue(ModelClass.class);
modelClassList.add(modelClass);
}

Here is the Firebase Realtime Database Image

ModelClass class and your database doesn't have the same structure, because in your database you have a new node called "phone" inside each userID node.
You can try 3 approaches to solve this issue:
a.) Write data in your database just like ModelClass is, without "phone" node.
b.) Create a new class called "Phone" with same attributes you have inside "phone" node in the database, and make this new class part of ModelClass class.
c.) On myRef onDataChange method, inside for statement, check for each child key and fill ModelClass atributes one by one. When the child key is equal to "phone", start a new loop statement in "phone" children to fill these attributes.

Add the following code:
#Override
public int getItemCount() {
return productList.size();
}

I don't know exactly and I much appreciate if you guys could tell about that more specifically as much as you can.

Save ArrayList<pojo> in SharedPreferences

I am using tabs which consist of fragment that has an arraylist of objects. I want to store my arraylist
list<Model_BarcodeDetail>
onStop() ie., I want to store my list that is present in my current tab when I navigate to another tab. I did the following code but it is giving me exception when I'm trying to save my list.
#Override
public void onPause() {
// TODO Auto-generated method stub
super.onPause();
System.out.println("=====pause");
saveDatas();
}
public void saveDatas() {
Log.d("msg", "Save Instance");
SharedPreferences.Editor outState = getActivity().getSharedPreferences(
"order", Context.MODE_APPEND).edit();
text = editText_barcode.getText().toString();
itemQuantity = editText_quantity.getText().toString();
outState.putString("saved", "true");
outState.putString("text", text);
outState.putString("title", job_name);
outState.putString("area", selected_area);
outState.putString("location", selected_loc);
outState.putString("quantity", itemQuantity);
//String strObject = gson.toJson(list, Model_BarcodeDetail.class);
//outState.putString("MyList", strObject);
POJO mPojo = new POJO();
mPojo.setData(list);
String strObject = gson.toJson(mPojo, POJO.class);
outState.putString("MyList", strObject);
outState.commit();
}
#Override
public void onActivityCreated(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onActivityCreated(savedInstanceState);
Bundle extras = getArguments();
/***** PUT DATA IN EDITTEXT if ITS AVAILABLE IN BUNDLE *****/
System.out.println("===jobname:"+job_name);
SharedPreferences orderData = getActivity().getSharedPreferences(
"order", Context.MODE_APPEND);
if (orderData != null) {
String a = orderData.getString("saved", "");
if (a != null && a.equalsIgnoreCase("true")) {
text = orderData.getString("text", "");
System.out.println("====tetx:" + text);
String title = orderData.getString("title", "");
System.out.println("===title: "+title+"===jobname: "+job_name);
if (title.equalsIgnoreCase(job_name)) {
editText_barcode.setText(text);
selected_area = orderData.getString("area", "");
selected_loc = orderData.getString("location", "");
itemQuantity = orderData.getString("quantity", "");
editText_quantity.setText(itemQuantity);
String json = orderData.getString("MyList", "");
List<Model_BarcodeDetail> list = gson.fromJson(json,
listOfObjects);
}
}
}
}
I'm getting the following exception when I add another tab:

public List<Model_BarcodeDetail> getData() {
return data;
}
public void setData(List<Model_BarcodeDetail> data) {
this.data = data;
}
}

You need to store your list in the model class like this
public class POJO {
List<Model_BarcodeDetail> data;
public List<Model_BarcodeDetail> getData() {
return data;
}
public void setData(List<Model_BarcodeDetail> data) {
this.data = data;
}
}
now when you have data in your POJO class
Convert it to json string and store to prefrence like this
String strObject = gson.toJson(list, POJO.class);
outState.putString("MyList", strObject);
Now when you want to get back those data just do like this
String json = orderData.getString("MyList", "");
POJO mPojo = gson.fromJson(json,POJO.class);
now access you List using this object like this
mPojo.getModel_BarcodeList();
Let me know if you still have an issue

You can use TinyDB -- Android-Shared-Preferences-Turbo

Android Realm return exception "Table has no columns"

This is my code:
PSTrip psTrip = JsonUtil.jsonToObject(jsonObject.toString(), PSTrip.class);
int size = psTrip.getTripSteps().size()-1;
RealmList<Step> steps = psTrip.getTripSteps().get(size).getSteps();
RealmList<TripStep> tripSteps = psTrip.getTripSteps();
Log.i("","continue init after getting tripsteps and steps");
if(tripSteps.size() > 0) {
Log.i("","continue init blabla");
for (int i = 0; i < tripSteps.size(); i++) {
RealmList<Step> mergedSteps = Utils.getMergedSteps(context, tripSteps.get(i).getRoute().getSteps());
tripSteps.get(i).getRoute().getSteps().clear();
for (Step step : mergedSteps) {
tripSteps.get(i).getRoute().getSteps().add(step);
}
}
Log.i("", "continue init after for in which I merge the steps for the tripsteps");
steps = Utils.getMergedSteps(context, steps);
Log.i("", "continue init after merging the steps");
tripSteps.get(size).setSteps(steps);
Log.i("", "continue init after settting steps on tripsteps");
psTrip.setTripSteps(tripSteps);
}
PSTripDBFactory.getInstance(context).addToList(psTrip);
The Utils.getMergedSteps just takes the list of steps (Step from Google maps class), and if it is possible, it merges them.
My problem is at the last line which does:
public void addToList(PSTrip psTrip){
try{
PSTrip insideAlready = getListOfCompletedTripsByID(psTrip.getId());
Log.i("","continue init inside already:" + insideAlready);
if(insideAlready == null){
Log.i("","continue init will copy to realm");
realm.beginTransaction();
realm.copyToRealm(psTrip);
realm.commitTransaction();
Log.i("","continue init will copy to realm finished");
}else{
Log.i("","continue init will copyorupdate to realm");
realm.beginTransaction();
realm.copyToRealmOrUpdate(psTrip);
realm.commitTransaction();
Log.i("","continue init will copyorupdate to realm finished");
}
}catch (Exception e){
Log.i("","continue init error trying to add to realm" + e.getMessage());
realm.cancelTransaction();
}
}
Where getListOfCompletedTripsByID is the following function:
public PSTrip getListOfCompletedTripsByID( String id){
RealmResults<PSTrip> completed = realm.where(PSTrip.class).equalTo("id" , id).findAll();
if(completed.size() > 0){
return completed.get(0);
}else{
return null;
}
}
I get back the following error response:
03-18 11:14:56.135 21908-21908/nl.hgrams.passenger I/﹕ continue init after for in which I merge the steps for the tripsteps
