Android Data Binding not Update UI after retreive data from webservice

I try to implement MVVM by Mindorks to show data from here :(https://api.themoviedb.org/3/movie/384018?api_key=67bc513a7a353631119fdffe5f7377a8&language=en-US) in my Activity. I try using databinding for update UI, but after the data is update, databinding not update my textview. here my Detail Activity Class :
public class DetailActivity extends BaseActivity<ActivityDetailBinding, DetailViewModel> implements DetailNavigator {
#Inject
DetailViewModel detailViewModel;
public static final String INTENT_ID = "id_intent";
public static final String INTENT_FLAG = "id_flag";
private ActivityDetailBinding mActivityDetailBinding;
public static Intent newIntent(Context context) {
return new Intent(context, DetailActivity.class);
}
#Override
public int getBindingVariable() {
return BR.viewModel;
}
#Override
public int getLayoutId() {
return R.layout.activity_detail;
}
#Override
public DetailViewModel getViewModel() {
return detailViewModel;
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_detail);
detailViewModel.setNavigator(this);
mActivityDetailBinding = getViewDataBinding();
initView();
initData(savedInstanceState);
}
private void initData(Bundle savedInstanceState) {
Bundle extras = getIntent().getExtras();
if (extras != null) {
int id = extras.getInt(INTENT_ID, 0);
int flag = extras.getInt(INTENT_FLAG, 0);
detailViewModel.fetchDetail(id, flag);
}
}
private void initView() {
if (getSupportActionBar() != null) {
getSupportActionBar().hide();
}
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
}
#Override
public void ShowProgressDialog(Boolean loading) {
if (loading) {
showLoading();
} else {
hideLoading();
}
}
}
and my BaseActivity like this :
public abstract class BaseActivity<T extends ViewDataBinding, V extends BaseViewModel> extends AppCompatActivity
implements BaseFragment.Callback {
// TODO
// this can probably depend on isLoading variable of BaseViewModel,
// since its going to be common for all the activities
private ProgressDialog mProgressDialog;
private T mViewDataBinding;
private V mViewModel;
/**

public abstract int getBindingVariable();
/**

*/
public abstract
#LayoutRes
int getLayoutId();
/**

*
* #return view model instance
*/
public abstract V getViewModel();
#Override
public void onFragmentAttached() {
}
#Override
public void onFragmentDetached(String tag) {
}
#Override
protected void onCreate(#Nullable Bundle savedInstanceState) {
performDependencyInjection();
super.onCreate(savedInstanceState);
performDataBinding();
}
public T getViewDataBinding() {
return mViewDataBinding;
}
#TargetApi(Build.VERSION_CODES.M)
public boolean hasPermission(String permission) {
return Build.VERSION.SDK_INT < Build.VERSION_CODES.M ||
checkSelfPermission(permission) == PackageManager.PERMISSION_GRANTED;
}
public void hideKeyboard() {
View view = this.getCurrentFocus();
if (view != null) {
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
if (imm != null) {
imm.hideSoftInputFromWindow(view.getWindowToken(), 0);
}
}
}
public void hideLoading() {
if (mProgressDialog != null && mProgressDialog.isShowing()) {
mProgressDialog.cancel();
}
}
public void showLoading() {
hideLoading();
mProgressDialog = CommonUtils.showLoadingDialog(this);
}
public boolean isNetworkConnected() {
return NetworkUtils.isNetworkConnected(getApplicationContext());
}
public void performDependencyInjection() {
AndroidInjection.inject(this);
}
#TargetApi(Build.VERSION_CODES.M)
public void requestPermissionsSafely(String[] permissions, int requestCode) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
requestPermissions(permissions, requestCode);
}
}
// public void showLoading() {
// hideLoading();
// mProgressDialog = CommonUtils.showLoadingDialog(this);
// }
private void performDataBinding() {
mViewDataBinding = DataBindingUtil.setContentView(this, getLayoutId());
this.mViewModel = mViewModel == null ? getViewModel() : mViewModel;
mViewDataBinding.setVariable(getBindingVariable(), mViewModel);
mViewDataBinding.setLifecycleOwner(this);
mViewDataBinding.executePendingBindings();
}
#Override

super.onResume();
}
#Override

}
}
this is my ViewModel class :
public class DetailViewModel extends BaseViewModel<DetailNavigator> {
private final ObservableField<String> originalName = new ObservableField<>();

public DetailViewModel(DataManager dataManager, SchedulerProvider schedulerProvider) {

}
public void fetchDetail(int id, int flag) {
if (flag == 1) {
getNavigator().ShowProgressDialog(true);
getCompositeDisposable().add(getDataManager()
.getApiHelper().doDetailMovie(id, URLConfig.API_KEY, getDataManager().getLanguage())
.subscribeOn(getSchedulerProvider().io())
.observeOn(getSchedulerProvider().ui())
.subscribe(detailResponse -> {

}
}
private void setUpData(DetailResponse detailResponse) {
if (detailResponse.getOriginal_name() != null) {
originalName.set(detailResponse.getOriginal_name());
} else {
originalName.set(detailResponse.getOriginal_title());
}
originalName.notifyChange();
if (detailResponse.getFirst_air_date() != null) {
releaseDate.set(detailResponse.getFirst_air_date());
} else {
releaseDate.set(detailResponse.getRelease_date());
}
overview.set(String.valueOf(detailResponse.getOverview()));
posterPath.set(String.valueOf(detailResponse.getPoster_path()));
voteAverage.set(String.valueOf(detailResponse.getVote_average()));
String genres = "";
for (int i = 0;i<detailResponse.getGenreList().size();i++){
genres = genres+detailResponse.getGenreList().get(i);
}
genreMovie.set(genres);
}
public ObservableField<String> getOriginalName() {
return originalName;
}
public ObservableField<String> getReleaseDate() {

}
public ObservableField<String> getOverview() {

return genreMovie;
}
public ObservableField<String> getPosterPath() {
return posterPath;
}
public ObservableField<String> getVoteAverage() {
return voteAverage;
}
}
and this is my DetailResponse Class :
public class DetailResponse {
#SerializedName("original_name")
private String original_name ;
#SerializedName("original_title")
private String original_title ;
#SerializedName("release_date")
private String release_date ;

}
public String getPoster_path() {

}
public List<Genre> getGenreList() {
return genreList;
}
public static class Genre{
#SerializedName("name")
private String name ;
public String getName() {
return name;
}
}
}
and last one, here how I try to get data in my UI using databinding, this is my layout :

I try to show one data first, that is OriginalName for text_title, went I debug my application
public ObservableField<String> getOriginalName() {
return originalName;
}
getOriginalName in class ViewModel, just called before I retrieve my response, but after OriginalName is set, the UI not update and getOriginalName is never called again.I already add originalName.notifyChange(); after the data is set, but it doesn't seem change anything.
I already frustased.. so please... I hope anybody can help me to show me what to do. Thank you very much.

Remove this below line from Detail Activity
setContentView(R.layout.activity_detail);
In your base activity you have performDataBinding method which set the layout id using DataBindingUtil class.
mViewDataBinding = DataBindingUtil.setContentView(this, getLayoutId());
this.mViewModel = mViewModel == null ? getViewModel() : mViewModel;
mViewDataBinding.setVariable(getBindingVariable(), mViewModel);
mViewDataBinding.setLifecycleOwner(this);
mViewDataBinding.executePendingBindings();

Bind boolean to checkbox MVVM

I am trying to bind a boolean through the viewmodel to the view, but Android Studio throws an error, and I can't find the problem. The viewModel.infilltype is a boolean, and android:checked should also be a boolean.
"error: '#{viewModel.infillType}' is incompatible with attribute android:checked (attr) boolean.
Message{kind=ERROR, text=error: '#{viewModel.infillType}' is incompatible with attribute android:checked (attr) boolean., sources=[E:\SportveldOnderhoud\app\src\main\res\layout\list_item_check.xml:14], original message=, tool name=Optional.of(AAPT)}"
I have the following code (I will paste snippets which are relevant)
Check.java (Model)
public class Check {
private UUID mId;
private String mTitle;
private Date mDate;
....
private boolean mInfilltype;
....
public Check() {
this(UUID.randomUUID());
}
public Check(UUID id) {
mId = id;
mDate = new Date();
}
public UUID getId() {
return mId;
}
....
public boolean isInfilltype() {
return mInfilltype;
}
public void setInfilltype(boolean infilltype) {
mInfilltype = infilltype;
}
}
ViewModel:
public class CheckViewModel extends BaseObservable {
private Check mCheck;
private Activity mActivity;
public CheckViewModel(Activity activity) {
mActivity = activity;
}
#Bindable
public String getTitle() {
return mCheck.getTitle();
}
#Bindable
public String getRenderedDate() {
return mCheck.getDate().toString();
}
#Bindable
public boolean infillType() {
return mCheck.isInfilltype();
}
public Check getCheck() {
return mCheck;
}
public void setCheck(Check crime) {
mCheck = crime;
List<String> strings;
notifyChange();
}
public void onCheckClicked() {
Intent intent = CheckPagerActivity.newIntent(mActivity, mCheck.getId());
mActivity.startActivity(intent);
}
}
View:
<?xml version="1.0" encoding="utf-8"?>
<layout>
<data>
<variable name="viewModel" type="nl.lekolkman.android.sportveldonderhoud.CheckViewModel" />
</data>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:onClick="#{() -> viewModel.onCheckClicked()}"
>
<CheckBox
android:id="#+id/solved_check_box"
android:checked="#{viewModel.infillType}"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"/>
<TextView
android:id="#+id/title_text_view"
android:text="#{viewModel.title}"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_toLeftOf="#id/solved_check_box"
android:textStyle="bold"
tools:text="Crime Title"/>
<TextView
android:id="#+id/date_text_view"
android:text="#{`Date solved: ` + viewModel.renderedDate ?? `(not solved)`}"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_toLeftOf="#id/solved_check_box"
android:layout_below="#id/title_text_view"
tools:text="Check Date"/>
</RelativeLayout>
</layout>

It turned out that I had to add:
android {
...
dataBinding {
enabled = true
}
in build.gradle
Then it still didn't work however, but after adding maven to the repositories in the build.gradle files it did work

I'm not super familiar with java, but I'm pretty sure in C# your boolean needs an initial value (not null) to bind properly.
Try changing
private boolean mInfilltype;
to
private boolean mInfilltype = false;

You can use or expand Android Compound View Binding Adapter

Some items from database not being displayed in cardview

I am having a problem with cardview not displaying some from the database.
My app connects to a grails back end which has a PostgreSQL db.
I have a cardview inside a recyclerview. It receives 7 values in form of JSON but on running the app, only 5 are displayed. I try doing System.out of the JSON in the stack trace and I find that all the 7 values are received so everything is okay on that front.
For clarity purposes, the fields that are not being displayed are labs("labs") and drugs administered("drugsAdministered").
Here is the main class(ClinicalHistory.java), the adapter class, the xml and the stack-trace.

The stack trace

I have found the solution. The problem was in the model.
This was my previous model. Note the parameters in the
setDrugs() and setLabs().
public class ClinicalHistory {
String img;
String date;
String labs;
String hospital;
String chiefComplains;
String doctor;
String drugs;
public ClinicalHistory() {
}
public String getImg() {
return img;
}
public void setImg(String img) {
this.img = img;
}
public String getHospital() {
return this.hospital = hospital ;
}
public void setHospital(String hospital) {
this.hospital = hospital;
}
public String getChiefComplains(){return this.chiefComplains = chiefComplains;}
public void setChiefComplains(String chiefComplains){ this.chiefComplains = chiefComplains;}
public String getLabs() {
return this.labs = labs ;
}
public void setLabs(String hospital) {
this.labs = labs;
}
public String getDoctor() {
return this.doctor = doctor ;
}
public void setDoctor(String doctor) {
this.doctor = doctor;
}
public void setDrugs(String hospital) {
this.drugs = drugs;
}
public String getDrugs() {
return this.drugs = drugs ;
}
public void setDate(String date) {
this.date = date;
}
public String getDate() {
return date;
}
}
After I made this change it worked
public class ClinicalHistory {
String img;
String date;
String labs;
String hospital;
String chiefComplains;
String doctor;
String drugs;
public ClinicalHistory() {
}
public String getImg() {
return img;
}
public void setImg(String img) {
this.img = img;
}
public String getHospital() {
return this.hospital = hospital ;
}
public void setHospital(String hospital) {
this.hospital = hospital;
}
public String getChiefComplains(){return this.chiefComplains = chiefComplains;}
public void setChiefComplains(String chiefComplains){ this.chiefComplains = chiefComplains;}
public String getLabs() {
return this.labs = labs ;
}
public void setLabs(String labs) {
this.labs = labs;
}
public String getDoctor() {
return this.doctor = doctor ;
}
public void setDoctor(String doctor) {
this.doctor = doctor;
}
public void setDrugs(String drugs) {
this.drugs = drugs;
}
public String getDrugs() {
return this.drugs = drugs ;
}
public void setDate(String date) {
this.date = date;
}
public String getDate() {
return date;
}
}

Add quantity to Ingredients

I want to make my database look like this:
FirebaseDB
I am adding ingredients' ingredientName from arrayList by looping them.
My question is how can I save easily quantity too. Measure will come from another DB path, when user added ingredientName
(for example "milk") to ListView.(but this is just a future plan, first I want to solve quantity)
Do I have to add EditText to list_item.xml ? Or how can I easily get quantity then save it?
The ingredientName saving method works perfectly but I don't know how can I easily store quantity for each ingredientName.
from AddIngredients activity:
private String key;
private ArrayList<String> arrayList=new ArrayList<>();
ListView listView=(ListView) findViewById(R.id.listv);
txtInput=(EditText) findViewById(R.id.IngredientsInput);
private DatabaseReference ingDBref = FirebaseDatabase.getInstance().getReference("Ingredients");
private DatabaseReference DBref= FirebaseDatabase.getInstance().getReference("Recipes");
adapter=new ArrayAdapter<String>(this,R.layout.list_item,R.id.ingredientName,arrayList);
listView.setAdapter(adapter);
public void addIngredients(){
final String IngredientName=txtInput.getText().toString();
ingDBref.addListenerForSingleValueEvent(new ValueEventListener() {
#Override
public void onDataChange(DataSnapshot dataSnapshot) {
for(DataSnapshot data: dataSnapshot.getChildren()){
if(data.child("ingredientName").getValue().equals(IngredientName)){
//If ingredientName=allowed ingredientNames from DB
arrayList.add(IngredientName);
adapter.notifyDataSetChanged();
Toast.makeText(this,"Added to ListView...",Toast.LENGTH_LONG).show();
}
else{
}
}
}
#Override
public void onCancelled(DatabaseError databaseError) {
}
});
}
public void saveIngredients(){
key=DBref.child.push().getKey();
String ingredientName;
for(int i=0;i<arrayList.size();i++){
ingredientName=arrayList.get(i);
Ingredients ingredients=new Ingredients(ingredientName);
DBref.child(key).child("Ingredients").child(ingredientName).setValue(ingredients);
}
Ingredients Class:
public class Ingredients {
String ingredientName;
// String ingredientQty;
// String measureName;
public Ingredients(){
}
public Ingredients(String IngredientName){
this.ingredientName=IngredientName;
// this.ingredientQty=IngredientQty;
//this.measureName=MeasureName;
}
#Override
public String toString() {
return super.toString();
}
public String getIngredientName(){
return ingredientName;
}
/*
public String getIngredientQty(){
return ingredientQty;
}*/
/*
public String getMeasureName(){
return measureName;
}*/
}

<?xml version="1.0" encoding="utf-8"?>

android:orientation="vertical" android:layout_width="match_parent"
