Is there any way to stop the progress bar from other class which is started in mainActivity
Kindly find the code
I am starting the progress bar in the main activity and then calling the method of other java class
where I am inserting data in firebase
I just want that after firebase insertion is successful progress bar should stop
but didn't find any way to do that
public class ProductDetails extends AppCompatActivity {
ProgressBar progressbar;
Button btn;
FirebaseDatabase firebaseDatabase;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_product_details);
progressbar = findViewById(R.id.btnprogressbar);
btn = findViewById(R.id.submit_btn);
firebaseDatabase = FirebaseDatabase.getInstance();
btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
progressbar.setVisibility(View.VISIBLE);
submitForm();
}
});
}
private void submitForm() {
FormDetailsServices formDetailsServices = new FormDetailsServices(ProductDetails.this);
FormDTO formDTO=generateForDTO();
formDetailsServices.submitForm(formDTO,firebaseDatabase);
}
}
My FormDetailsServices:
public class FormDetailsServices {
Context context;
final String TAG = "FormDetailsServices";
public FormDetailsServices(Context context) {
this.context = context;
}
public Context getContext() {
return context;
}
public void setContext(Context context) {
this.context = context;
}
public void submitForm(FormDTO formDTO,FirebaseDatabase firebaseDatabase) {
firebaseDatabase
.getReference()
.child("test")
.setValue(formDTO)
.addOnSuccessListener(new OnSuccessListener<Void>() {
#Override
public void onSuccess(Void aVoid) {
Log.d(TAG,"form submitted Successfully");
//here i want to stop progressbar
}
}).addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception e) {
Log.d(TAG,"form submittion Failed exception msg= " + e.getMessage());
}
});
}
}
Everything is working fine its getting inserted to Firebase but progressbar is still visible
You can create an interface in FormDetailsServices class and implement it to your main class, and then you can hide the progress bar by calling its methods in main class as below -
public class ProductDetails extends AppCompatActivity implements FormDetailsServices.OnFormSubmissionListener{
ProgressBar progressbar;
Button btn;
FirebaseDatabase firebaseDatabase;
OnFormSubmissionListener listener;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_product_details);
progressbar = findViewById(R.id.btnprogressbar);
btn = findViewById(R.id.submit_btn);
firebaseDatabase = FirebaseDatabase.getInstance();
btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
progressbar.setVisibility(View.VISIBLE);
submitForm();
}
});
}
private void submitForm() {
FormDetailsServices formDetailsServices = new
FormDetailsServices(ProductDetails.this);
formDetailsServices.setOnFormSubmissionListener(this);
FormDTO formDTO=generateForDTO();
formDetailsServices.submitForm(formDTO,firebaseDatabase);
}
#Override
public void onSubmissionSuccess() {
progressbar.setVisibility(View.GONE);
}
#Override
public void onSubmissionFailure() {
progressbar.setVisibility(View.GONE);
}
}
and for FormDetailsServices
public class FormDetailsServices {
Context context;
final String TAG = "FormDetailsServices";
OnFormSubmissionListener listener;
public FormDetailsServices(Context context) {
this.context = context;
}
public Context getContext() {
return context;
}
public void setContext(Context context) {
this.context = context;
}
void setOnFormSubmissionListener(OnFormSubmissionListener listener){
this.listener = listener;
}
public void submitForm(FormDTO formDTO,FirebaseDatabase firebaseDatabase) {
firebaseDatabase
.getReference()
.child("test")
.setValue(formDTO)
.addOnSuccessListener(new OnSuccessListener<Void>() {
#Override
public void onSuccess(Void aVoid) {
Log.d(TAG,"form submitted Successfully");
//here i want to stop progressbar
listener.onSubmissionSuccess();
}
}).addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception e) {
listener.onSubmissionFailure();
Log.d(TAG,"form submittion Failed exception msg= " + e.getMessage());
}
});
}
interface OnFormSubmissionListener {
void onSubmissionSuccess();
void onSubmissionFailure();
}
}

I use mvp architecture.
I have the setupViews () method in which the buttons and ... are defined
how i can use setOnclickListener for Button in "presenter" and call it in SetupViews in "activity".
I do not want to use it directly in "view",I want to tell the presenter that the click is done and the presenter will do the job.
My interface:
public interface HomeContract {
interface View extends BaseView {
void showNews(List<News> newsList);
void showError(String error);
}
interface Presenter extends BasePresenter<View> {
void getNewsList();
} }
presenter class :
public class HomePresenter implements HomeContract.Presenter {
private HomeContract.View view;
private NewsDataSourse newsDataSourse;
CompositeDisposable compositeDisposable = new CompositeDisposable();
public HomePresenter(NewsDataSourse newsDataSourse) {
this.newsDataSourse = newsDataSourse;
}
#Override
public void getNewsList() {
newsDataSourse.getNews().subscribeOn(Schedulers.newThread())
.observeOn(AndroidSchedulers.mainThread())
.subscribe(new SingleObserver<List<News>>() {
#Override
public void onSubscribe(Disposable d) {
compositeDisposable.add(d);
}
#Override
public void onSuccess(List<News> news) {
view.showNews(news);
}
#Override
public void onError(Throwable e) {
view.showError(e.toString());
}
});
}
#Override
public void attachView(HomeContract.View view) {
this.view = view;
getNewsList();
}
#Override
public void detachView() {
this.view = null;
if (compositeDisposable != null && compositeDisposable.size() > 0) {
compositeDisposable.clear();
}
}}
my view :
public class HomeActivity extends BaseActivity implements HomeContract.View {
private HomeContract.Presenter presenter;
private NewsRepository newsRepository = new NewsRepository();
private RecyclerView recyclerView;
private RecyclerAdapter recyclerAdapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_home);
presenter = new HomePresenter(newsRepository);
}
#Override
public void setupViews() {
Button btn_Ok = (Button) findViewById(R.id.btn_Ok);
recyclerView = (RecyclerView) findViewById(R.id.recycler);
recyclerView.setLayoutManager(new LinearLayoutManager(getViewContext(), LinearLayout.VERTICAL, false));
// btn_Ok.setOnClickListener();
}
#Override
public void showNews(List<News> newsList) {
setupViews();
recyclerView.setAdapter(new RecyclerAdapter(newsList, getViewContext()));
if (newsList.size() > 0) {
Toast.makeText(getViewContext(), "ok", Toast.LENGTH_SHORT).show();
Toast.makeText(getViewContext(), newsList.get(0).getName(), Toast.LENGTH_SHORT).show();
} else
Toast.makeText(getViewContext(), "not Ok", Toast.LENGTH_SHORT).show();
}
#Override
public void showError(String error) {
Toast.makeText(getViewContext(), error, Toast.LENGTH_SHORT).show();
}
#Override
public Context getViewContext() {
return getApplicationContext();
}
#Override
protected void onStart() {
super.onStart();
presenter.attachView(this);
}
#Override
protected void onStop() {
super.onStop();
presenter.detachView();
}
}
i want to use btn_Ok.setOnClickListener(presenter....); in view Or any better solution you need to do this
In your presenter interface type a method :
interface Presenter extends BasePresenter<View> {
void getNewsList();
void onButtonClicked();
}
And than in your HomePresenter class use it :
#Override
public void onButtonClicked(){
// continue logic here
}
If you don't override it the class will show an error
There is a program where I can change a variable using a singleton. Created 2 activites, where users can change this variable. How to write the variable that is being changed to the Firebase database. I tried to use the addValueEventListener (new ValueEventListener () method.
Where do I use the firebase methods? In the main class or in singleton? And how to write a variable?
main activity
public class MainActivity extends AppCompatActivity {
private BubbleWrap bubbleWrap;
private TextView txtintent;
final int REQUEST_CODE_661_1 = 1;

I am trying to use RxAndroid to do the same work which is AsyncTask exactly does. I coded a simple example, where I enter a n integer in an edittext and when I press
a button, I make the hread to sleep for 3 seconds using "SystemClock.sleep" and while the thread is sleeping I show a progressbar and when the three seconds
elapsed the progresssbar will adisappear and the value entered in the edittext will be multiplied by 10 and displayed in atextview.
normally, when I use AsyncTask, I show the progressbar in onPreExecute and make it to disappear in onPostExecute. but when I run the below code I receive the
following error:
Only the original thread that created a view hierarchy can touch its views.
how to handle it properly in RxAndroid?
code:
public class MainActivity extends AppCompatActivity {
private static final String TAG = MainActivity.class.getSimpleName();
private EditText mEditTextValueToProcess = null;
private Button mButtonGoAsynchronous = null;
private TextView mTextViewProcessedValue = null;
private ProgressBar mProgressBar = null;
private rx.Observable<String> mAsyncObservable = null;
Subscriber mAsyncSubscriber = new Subscriber<String>() {
#Override
public void onCompleted() {
Log.w(TAG, "onCompleted");
mProgressBar.setVisibility(View.GONE);
}
#Override
public void onError(Throwable e) {
Log.w(TAG, "onError: " + e.getMessage().toString());
mProgressBar.setVisibility(View.GONE);
}
#Override
public void onNext(String o) {
Log.w(TAG, "onNext:->after processing " + o);
mTextViewProcessedValue.setText(o);
}
};
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
intiViews();
mAsyncObservable = rx.Observable.create(new rx.Observable.OnSubscribe<String>() {
#Override
public void call(Subscriber<? super String> subscriber) {
mProgressBar = (ProgressBar) findViewById(R.id.progressDialog);
mProgressBar.setVisibility(View.VISIBLE);
SystemClock.sleep(3000);
subscriber.onNext("" + Integer.valueOf(mEditTextValueToProcess.getText().toString()) * 10);
subscriber.onCompleted();
}
});
}
private void intiViews() {
mEditTextValueToProcess = (EditText) findViewById(R.id.edittext);
mButtonGoAsynchronous = (Button) findViewById(R.id.button_go_asynchronous);
mTextViewProcessedValue = (TextView) findViewById(R.id.textview_processed_value);
//mProgressBar = (ProgressBar) findViewById(R.id.progressDialog);
mButtonGoAsynchronous.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mAsyncObservable.subscribeOn(Schedulers.io())
.observeOn(AndroidSchedulers.mainThread())
.subscribe(mAsyncSubscriber);
}
});
}
}
Have you tried
private Observable<String> createObservable(final int number) {
return rx.Observable.create(new rx.Observable.OnSubscribe<String>() {
#Override
public void call(Subscriber<? super String> subscriber) {
SystemClock.sleep(3000);
subscriber.onNext("" + number * 10);
subscriber.onCompleted();
}
});
}
private void intiViews() {
mEditTextValueToProcess = (EditText) findViewById(R.id.edittext);
mButtonGoAsynchronous = (Button) findViewById(R.id.button_go_asynchronous);
mTextViewProcessedValue = (TextView) findViewById(R.id.textview_processed_value);
mProgressBar = (ProgressBar) findViewById(R.id.progressDialog);
mButtonGoAsynchronous.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mProgressBar.setVisibility(View.VISIBLE);
createObservable(Integer.valueOf(mEditTextValueToProcess.getText().toString()))
.subscribeOn(Schedulers.io())
.observeOn(AndroidSchedulers.mainThread())
.doOnNext((ignored) -> {
mProgressBar.setVisibility(View.GONE);
})
.subscribe(mAsyncSubscriber);
}
});
}
?
You need to change few things to achieve this. Look at mAsyncSubscriber initialization, onStart() method & progressBar initialization. The reason why you are getting the error is you are initializing & making your progressbar visible in another thread then your UI thread (because you specified this -> subscribeOn(Schedulers.io()).
public class MainActivity extends AppCompatActivity {
private static final String TAG = MainActivity.class.getSimpleName();
private EditText mEditTextValueToProcess = null;
private Button mButtonGoAsynchronous = null;
private TextView mTextViewProcessedValue = null;
private ProgressBar mProgressBar = null;
private rx.Observable<String> mAsyncObservable = null;
Subscriber mAsyncSubscriber;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
intiViews();
mAsyncSubscriber = new Subscriber<String>() {
// Override onStart method
#Override
public void onStart() {
mProgressBar.setVisibility(View.VISIBLE);
}
#Override
public void onCompleted() {
Log.w(TAG, "onCompleted");
mProgressBar.setVisibility(View.GONE);
}
#Override
public void onError(Throwable e) {
Log.w(TAG, "onError: " + e.getMessage().toString());
mProgressBar.setVisibility(View.GONE);
}
#Override
public void onNext(String o) {
Log.w(TAG, "onNext:->after processing " + o);
mTextViewProcessedValue.setText(o);
}
};
mAsyncObservable = rx.Observable.create(new rx.Observable.OnSubscribe<String>() {
#Override
public void call(Subscriber<? super String> subscriber) {
SystemClock.sleep(3000);
subscriber.onNext("" + Integer.valueOf(mEditTextValueToProcess.getText().toString()) * 10);
subscriber.onCompleted();
}
});
}
private void intiViews() {
// Init your progressbar
mProgressBar = (ProgressBar) findViewById(R.id.progressDialog);
mEditTextValueToProcess = (EditText) findViewById(R.id.edittext);
mButtonGoAsynchronous = (Button) findViewById(R.id.button_go_asynchronous);
mTextViewProcessedValue = (TextView) findViewById(R.id.textview_processed_value);
//mProgressBar = (ProgressBar) findViewById(R.id.progressDialog);
mButtonGoAsynchronous.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mAsyncObservable.subscribeOn(Schedulers.io())
.observeOn(AndroidSchedulers.mainThread())
.subscribe(mAsyncSubscriber);
}
});
}
