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();
/**
* #return layout resource id
*/
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

}
this is my ViewModel class :

}
}
private void setUpData(DetailResponse detailResponse) {
if (detailResponse.getOriginal_name() != null) {

}
originalName.notifyChange();
if (detailResponse.getFirst_air_date() != null) {

}
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 genreMovie;
}
public ObservableField<String> getPosterPath() {
return posterPath;
}
public ObservableField<String> getVoteAverage() {

}
}
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();

Show hide alternate LinearLayouts when selecting RadioButton in 2 RadioGroups

Six RadioButtons aligned as 3 columns and 2 rows in a RadioGroup, so 6 RB-s in RG. If user selects a RB, right under it image1 and text1 are shown and under alternated RB-s image1 and text2 are also shown. User may select any RB. The proper behavior looks like that https://photos.app.goo.gl/NEqTaxsY6daxD3kJA

Image1 is always the same, while text1 and text2 differ. Text1 'You' is shown under the selected RB and text2 'Your friend' - under alternating RB-s.
The quetion still is how to show/hide image1 and text 1 or text 2 alternatively?
I can show/hide image1 and text-s under RB-s which is in the same column, but not alternating RB-s.

Changing Background color not working

I am trying to get the background to change on click after 500 ms. All it does right now is go black. It doesn't even show the view just a black screen. The list of colors comes from a database, the JSON data is parsed for the color value. I am using Android 6 API 23.

Android Custom BaseAdapter getView not called

So, I have scoured the interwebs and I cannot find a solution for this based on other people's experiences, so I am posting this issue. (Please note that this is my 1st android app experience and I am debugging / updating an existing app.)
When I implement my custom NotesListAdapter (extends BaseAdapter) on the ListView, mListNotesView (mListNotesView.setAdapter(this)), and load the data into the ArrayList mNoteList, the getView function is not being called. Also, I found that mListNotesView.setBackgroundResource is not chaning the background of the control, either. I have a similar implementation on a previous activity that works exactly correct. When I copied over the class and changed it to handle my ArrayList, it broke. I have getCount returning the ArrayList size(), which is not 0, and getItemId returns position. I have a feeling it may be my XML or my setup because it's acting like the ListView is not visible. I am perplexed. How do I get the ListView to show? Anything inside of the getView has not been reached so it may be buggy.

I'm going to recommend you reorganize your code. Here are some general tips:
1) Keep your views like ListView in the Activity class. Don't try to inflate the view in your adapter class. So in your activity's onCreate() after setContentView() you should have something like:
ListView listView = (ListView) findViewById(R.id.listView);
2) Next you need to get the data that will be shown in the listview and store it in a list. I didn't see in your code where the data comes from, but let's just say it comes from a database. You should create something like an ArrayList and store the data that you want to show in the ListView in the ArrayList
3) Next you need to create an adapter and pass the list of data into the adapter.
4) Once this has been done the ListView now has an adapter that will supply data to it. If you've done everything correctly then the system will eventually call getView() automatically and your code inside that should run and render the view.
Not an exact solution, but hopefully this explanation will help you figure it out.
