Firebase real database values differ from the retrieved ones

So, in realtime database I have:
When I retrieve data from database I get:
Model class looks like:
public class User implements Parcelable {
public static final Parcelable.Creator<User> CREATOR = new Parcelable.Creator<User>() {
#Override
public User createFromParcel(Parcel source) {
return new User(source);
}
#Override
public User[] newArray(int size) {
return new User[size];
}
};
...
private String hasToPayFromPastRides;
private String didNotPayCount;
...;
public User() {
}
public User(..., String didNotPayCount, String hasToPayFromPastRides) {
...
this.didNotPayCount = didNotPayCount;
this.hasToPayFromPastRides = hasToPayFromPastRides;
}
protected User(Parcel in) {
...
this.didNotPayCount = in.readString();
this.hasToPayFromPastRides = in.readString();
}
...
public String getDidNotPayCount() {
return didNotPayCount;
}
public void setDidNotPayCount(String didNotPayCount) {
this.didNotPayCount = didNotPayCount;
}
public String hasToPayFromPastRides() {
return hasToPayFromPastRides;
}
public void setHasToPayFromPastRides(String hasToPayFromPastRides) {
this.hasToPayFromPastRides = hasToPayFromPastRides;
}
#Override
public int describeContents() {
return 0;
}
#Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeString(this.userId);
dest.writeString(this.userFullName);
dest.writeString(this.userEmail);
dest.writeString(this.userPhoneNumber);
dest.writeString(this.userAvatarUrl);
dest.writeString(this.userLocalAvatar);
dest.writeString(this.userAddress);
dest.writeString(this.userCity);
dest.writeString(this.userArea);
dest.writeString(this.userPostalCode);
dest.writeString(this.userRating);
dest.writeString(this.userTotalRating);
dest.writeString(this.totalTrips);
dest.writeString(this.riskCount);
dest.writeString(this.isBlocked);
dest.writeString(this.isDefaulter);
dest.writeString(this.pendingRating);
dest.writeParcelable(this.pendingRateObj, flags);
dest.writeString(this.didNotPayCount);
dest.writeString(this.hasToPayFromPastRides);
}
}
What surprises me is that one value gets read correctly "didNotPayCount" when "hasToPayFromPastRides" is null. Any ideas?

Your getter isn't named correctly:
public String hasToPayFromPastRides()
It should be:
public String getHasToPayFromPastRides()

How to send ArrayList<Object> to other Fragment/Activity without init (start) the next Activity?

I have an ArrayList and I need to send it to another fragment. I tried to use Parcelable, but to send the data I need the "startIntent" method which starts the fragment. I don't want the fragment to be started.
I need send data array list object to another fragment without going to this other fragment. I only need to send the data. The user is free to chose when to change between activities/fragments. And the data sent earlier should already be there.
Example using Parcelable:
Class that must be to sent:
import android.os.Parcel;
import android.os.Parcelable;

There are multiple ways with different complexity for the implementation.
Use a database to store what you need there
Store the data in the host activity containing the tabs. As soon as you switch the fragment, all you need to do is read the data from the place where you have stored it.
Use LiveData. LiveData would be my personal preference. There you can easily store any data you need and the second fragment simply observes the livedata and can easily react to changes. So you could even switch in both directions as often as you want to.

Try Using EventBus.
To use EventBus, you need to first add it to in the app module build.gradle file
implementation 'org.greenrobot:eventbus:3.1.1'
and then sync your project.
An Event Subscriber
A subscriber simply subscribes to an event by registering in the event bus and can also unregister that event. To be a subscriber, you have to do three main things:
Register the subscriber in the event bus with register(). This informs the event bus that you want to begin receiving events. In an activity, this is in the onStart() method, while in a fragment put this in the onAttact(Activity activity) method.
#Override
public void onStart() {
super.onStart();
EventBus.getDefault().register(this);
}
Unregister the subscriber, which means tell the event bus to stop sending me events. In an activity, this is in the onStop() method, while in a fragment put this in the onDetach() method.
#Override
public void onStop() {
super.onStop();
EventBus.getDefault().unregister(this);
}
Implement the onEvent() to indicate the type of event you want to receive and action to take when you receive the event. Notice the #Subscribe annotation at the top of this method.
#Subscribe
public void onEvent(MessageEvent event) {
Toast.makeText(this, "Hey, my message" + event.getMessage(),
Toast.LENGTH_SHORT).show();.
}
Defining Event Messages
The events in greenrobot EventBus are just objects that you define. You can have different event classes if you want. They do not inherit any base class or interface—they're just POJO (Plain Old Java Objects).
public class MessageEvent {
public final List<SomeItem> items;
public MessageEvent(List<SomeItem> items) {
this.items= items;
}
}
Post Event
EventBus.getDefault().post(new MessageEvent("Hey event subscriber!"));

How to populate values to variables of a parcelable class whose object we are sending from one activity to the other

This is the FirstActivity:
void handleBlogEditClick(){
if (BlogDetailActivity.this!= null) {
BlogDetailVO blogDetailVO=new BlogDetailVO(getArgs().getmId(),getArgs().getmName().toString(),getArgs().getmDescription().toString());
blogDetailVO.mCoverPic.setmImageUrl(getArgs().getmImageUrl());
Intent intent = new Intent(BlogDetailActivity.this, EditBlogActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
intent.putExtra("blogDetailVO",blogDetailVO);
startActivity(intent);
}
}
Second activity:
mState = new EditBlogState();
Intent intent = getIntent();
BlogDetailVO blogDetailVO =(BlogDetailVO) intent.getParcelableExtra("blogDetailVO");
mState.mCoverPhotoStory.setmName(blogDetailVO.getmName());
mView.updateBlogTitle(mState.mCoverPhotoStory.getmName());
Other things in the first and second activity code is irrelevant to this so i shared this much
public class BlogDetailVO extends BlogFeedVO implements Parcelable{
PhotoStoryVO mCoverPic;
List<PhotoStoryVO> mPhotoStories;
LocationVO mLocationVO;
public BlogDetailVO(String mId, String mName, String mDescription) {
super(mId, mName, mDescription);
}
protected BlogDetailVO(Parcel in) {
super(in);
mCoverPic = in.readParcelable(PhotoStoryVO.class.getClassLoader());
mPhotoStories = in.createTypedArrayList(PhotoStoryVO.CREATOR);
mLocationVO = in.readParcelable(LocationVO.class.getClassLoader());
}
#Override
public void writeToParcel(Parcel dest, int flags) {
super.writeToParcel(dest, flags);
dest.writeParcelable(mCoverPic, flags);
dest.writeTypedList(mPhotoStories);
dest.writeParcelable(mLocationVO, flags);
}
#Override

}
#Override
public BlogDetailVO[] newArray(int size) {
return new BlogDetailVO[size];
}
};
public PhotoStoryVO getmCoverPic() {
return mCoverPic;
}
public void setmCoverPic(PhotoStoryVO mCoverPic) {
this.mCoverPic = mCoverPic;
}
public List<PhotoStoryVO> getmPhotoStories() {
return mPhotoStories;
}
public void setmPhotoStories(List<PhotoStoryVO> mPhotoStories) {
this.mPhotoStories = mPhotoStories;
}
public LocationVO getmLocationVO() {
return mLocationVO;
}
public void setmLocationVO(LocationVO mLocationVO) {
this.mLocationVO = mLocationVO;
}
}
I am new to android. so sorry if the question is silly. But i am really stuck and need help. i am sending BlogDetailVO class object to another activity. The second line is showing null. so can't i populate value in this way? Eventually it crashes.
BlogDetailVO blogDetailVO=new BlogDetailVO(getArgs().getmId(),getArgs().getmName().toString(),getArgs().getmDescription().toString());
blogDetailVO.mCoverPic.setmImageUrl(getArgs().getmImageUrl()); //this gives the error!!
Intent intent = new Intent(BlogDetailActivity.this, EditBlogActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
intent.putExtra("blogDetailVO",blogDetailVO); startActivity(intent);
So how to populate values to BlogDtailVO class so to send it to the other activity?
In the receiving activity I am receiving it this way:
Intent intent = getIntent();
BlogDetailVO blogDetailVO =(BlogDetailVO) intent.getParcelableExtra("blogDetailVO");

Android: passing object between activities and make it parcelable

New to Android programming. Having trouble to pass the object between activities and make it parcelable. Could somebody tell me what the problem could be? I want to know whether the logic is sound.
public class MainActivity extends Activity {
private Bundle MyActivityParams;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Intent intent = new Intent(this, MyActivity.class);
MyActivityParams = fillInData(MyActivityParams);
intent.putExtras(MyActivityParams);
startActivity(intent, savedInstanceState);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
private Bundle fillInData(Bundle bundle){
bundle.putFloat("com.company.MyActivity.FL", 12);
bundle.putFloat("com.company.MyActivity.VH", 100);
bundle.putFloat("com.company.MyActivity.const", 1);
return bundle;
}
}
public class DisplayActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
displayData();
}
private void displayData(){
//ActivityData is from MyActivity
ActivityData data = new ActivityData(getIntent().getExtras());
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.activity_display, menu);
return true;
}
}
public class MyActivity extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
displayParams();
}
private void displayParams(){
ActivityData dataBundle = new ActivityData((getIntent()).getExtras());
transfer(dataBundle);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_algorithm, menu);
return true;
}
public void transfer(ActivityData incomingdata){
startActivity(incomingdata.getIntent());
}
protected static class ActivityData{
private Bundle data;
private TextView text;
private Intent intent;
public ActivityData(Bundle bundle){
/*data = bundle;
intent = new Intent(null, DisplayActivity.class);
text = new TextView(null);*/
}
public void display(String key){
this.text.setText(data.getString(key));
//not allowed: startActivity(intent);
//not allowed either: setContentView(text);
}
public Intent getIntent() {
return intent;
}
public void setIntent(Intent intent) {
this.intent = intent;
}
public TextView getText() {
return text;
}
public void setText(TextView text) {
this.text = text;
}
public Bundle getData() {
return data;
}
public void setData(Bundle data) {
this.data = data;
}
}
}

Let's have a Person class
public class Person {
private String name;
private String email;
private int age;
public Person(int age, String name, String email) {
this.age = age;
this.name = name;
this.email = email;
}
}
A parcelable one would look like this
public class ParcelablePerson implements Parcelable {
private final Person person;
private ParcelablePerson(Parcel parcel) {
this.person = new Person(parcel.readInt(), parcel.readString(), parcel.readString());
}
public ParcelablePerson(Person person) {
this.person = person;
}
public Person getPerson() {
return person;
}
#Override
public int describeContents() {
return 0;
}
// This is the method where you disassembly your object to pieces
#Override
public void writeToParcel(Parcel parcel, int flags) {
parcel.writeInt(person.getAge());
parcel.writeString(person.getName());
parcel.writeString(person.getEmail());
}
public static final Creator<ParcelablePerson> CREATOR = new Creator<ParcelablePerson>() {
// And here you create a new instance from a parcel using the first constructor
#Override
public ParcelablePerson createFromParcel(Parcel parcel) {
return new ParcelablePerson(parcel);
}
#Override
public ParcelablePerson[] newArray(int size) {
return new ParcelablePerson[size];
}
};
}
The crucial thing in the process is to have the same order of the variables in private ParcelablePerson(Parcel parcel) constructor and public void writeToParcel(Parcel parcel, int flags) method... You can see it on the age property which is an int.

try this one.
ParcelTest.java
import java.util.HashMap;
import android.os.Parcel;
import android.os.Parcelable;
public class ParcelTest implements Parcelable {
private HashMap map;
public ParcelTest() {
map = new HashMap();
}
public ParcelTest(Parcel in) {
map = new HashMap();
readFromParcel(in);
}
public static final Parcelable.Creator CREATOR = new Parcelable.Creator() {
public ParcelTest createFromParcel(Parcel in) {
return new ParcelTest(in);
}
public ParcelTest[] newArray(int size) {
return new ParcelTest[size];
}
};
#Override
public int describeContents() {
return 0;
}
#Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeInt(map.size());
for (String s: map.keySet()) {
dest.writeString(s);
dest.writeString(map.get(s));
}
}
public void readFromParcel(Parcel in) {
int count = in.readInt();
for (int i = 0; i < count; i++) {
map.put(in.readString(), in.readString());
}
}
public String get(String key) {
return map.get(key);
}
public void put(String key, String value) {
map.put(key, value);
}
}
ExampleSupplierActivity.java
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
public class ExampleSupplierActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
ParcelTest p = new ParcelTest();
p.put("green", "go");
p.put("yellow", "wait");
p.put("red", "stop");
Bundle b = new Bundle();
b.putParcelable("com.example.trafficlight", p);
Intent i = new Intent(this, ExampleConsumerActivity.class);
i.putExtras(b);
startActivity(i);
}
}
ExampleConsumerActivity.java
import android.app.Activity;
import android.os.Bundle;
public class ExampleConsumerActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Bundle b = getIntent().getExtras();
ParcelTest p = b.getParcelable("com.example.trafficlight");
String red = p.get("red");
// ...
}
}

try this out this code work for me. but i have implement serializable rather than parcelable.
Try to implement parcelable rather than serializable . and try it if its work. i havnt tried this but implementing parcelable.
To pass and object to another activity:
in activity A
make sure the class implements the serializable interface
create a new intent
create a new bundle
use the putSerializeable method to add the object to the bundle with a key
put the bundle in the intent by using the putExtras method
start the activity using the startActivity method
Specifically,
Intent intent = new Intent(ShoulderExerciseScreen.this, ExercisesScreen.class);
Bundle bundle = new Bundle();
bundle.putSerializable("exercise", new Exercise("BenchPress));
intent.putExtras(bundle);
startActivity(intent);
in activity B
declare and object of the type you want passed
use the getIntent method to get the intent
use the getSerializeableExtra to get the the value using the key
cast the returned value from getSerializeableExtra and the desired type
Specifically,
Exercise ex = (Exercise)getIntent().getSerializableExtra("exercise");
if(ex != null)
{
//do something
}

Passing ArrayLists in Android

I'm trying to pass array lists between activities in Android. The lists contains strings. I've read a lot about Parcelable. Would I need to create a Parcelable to pass a String array list? As of now I am using putStringArrayListExtra() and getSringArrayListExtra() to pass the lists through intents.
Here is some of my code.
Intent load = new Intent(getApplicationContext(), HelloTabWidget.class);
load.putStringArrayListExtra("albums", albums);
load.putStringArrayListExtra("songs", songs);
load.putStringArrayListExtra("artists", artists);
load.putStringArrayListExtra("fileName", fileName);
This is my onCreate method for the acticity which obtains the array list.
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.songlist);
Bundle extras = getIntent().getExtras();
isArtists = extras.getBoolean("artists");
isAlbums = extras.getBoolean("albums");
isSongs = extras.getBoolean("songs");
Intent get = getIntent();
songs = get.getStringArrayListExtra("songs");
artists = get.getStringArrayListExtra("artists");
albums = get.getStringArrayListExtra("albums");
fileName = get.getStringArrayListExtra("fileName");
if(isArtists == true)
updateArtistsList();
else if(isAlbums == true)
updateAlbumsList();
else if(isSongs == true)
updateSongList();
}
The class which retrieves the list is supposed to create a listView from the data in the lists. Whenever I run the code i get nullPointerExceptions when trying to make the lists. I know that my listView code works, so I have narrowed down the problem to the intents which pass the array lists.
Thanks in advance.
EDIT:
Here are the first few lines from the logcat.
12-28 03:03:42.313: E/AndroidRuntime(873): FATAL EXCEPTION: main
12-28 03:03:42.313: E/AndroidRuntime(873): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.adam.mediaplayer/com.adam.mediaplayer.HelloTabWidget}: java.lang.RuntimeException: Unable to start activity ComponentInfo{com.adam.mediaplayer/com.adam.mediaplayer.MakeListActivity}: java.lang.NullPointerException

It depends on the type of arraylist
putIntegerArrayListExtra(String name, ArrayList<Integer> value)
putParcelableArrayListExtra(String name, ArrayList<? extends Parcelable> value)
putStringArrayListExtra(String name, ArrayList<String> value)
putCharSequenceArrayListExtra(String name, ArrayList<CharSequence> value)
Then you can read from you next activity by replacing put with get with key string as argument,eg
myIntent.getStringArrayListExtra("arrayListName");

Here is how you can pass an ArrayList :
MyListClass.java - Custom class
