For Kotlin in Android        override fun onBackPressed             confirmToCancel              private fun confirmToCancel             AlertDialog Builder this               setTitle  Title                setMessage  Do you want to cancel                 setCancelable false               setPositiveButton  Yes                     dialog  DialogInterface     Int - gt                  dialog dismiss                      for sending data to previous activity use                    setResult response code  data                  finish                              setNegativeButton  No                     dialog  DialogInterface     Int - gt                  dialog dismiss                              show

AlertDialog Builder really isn t that hard to use  It s a bit intimidating at first for sure  but once you ve used it a bit it s both simple and powerful  I know you ve said you know how to use it  but here s just a simple example anyway   DialogInterface OnClickListener dialogClickListener   new DialogInterface OnClickListener          Override     public void onClick DialogInterface dialog  int which            switch  which           case DialogInterface BUTTON POSITIVE                Yes button clicked             break           case DialogInterface BUTTON NEGATIVE                No button clicked             break                      AlertDialog Builder builder   new AlertDialog Builder context   builder setMessage  Are you sure    setPositiveButton  Yes   dialogClickListener       setNegativeButton  No   dialogClickListener  show      You can also reuse that DialogInterface OnClickListener if you have other yes no boxes that should do the same thing   If you re creating the Dialog from within a View OnClickListener  you can use view getContext   to get the Context  Alternatively you can use yourFragmentName getActivity

Steves answer is correct though outdated with fragments  Here is an example with FragmentDialog   The class   public class SomeDialog extends DialogFragment         Override     public Dialog onCreateDialog Bundle savedInstanceState            return new AlertDialog Builder getActivity                 setTitle  Title                setMessage  Sure you wanna do this                 setNegativeButton android R string no  new OnClickListener                      Override                 public void onClick DialogInterface dialog  int which                           do nothing  will close dialog                                                setPositiveButton android R string yes   new OnClickListener                      Override                 public void onClick DialogInterface dialog  int which                           do something                                               create              To start dialog               FragmentTransaction ft   getSupportFragmentManager   beginTransaction                   Create and show the dialog              SomeDialog newFragment   new SomeDialog                 newFragment show ft   dialog      You could also let the class implement onClickListener and use that instead of embedded listeners

you can implement a generic solution for decisions and use in another case not just for yes no and custom the alert with animations or layout   Something like this  first create your class for transfer datas   public class AlertDecision        private String question           private String strNegative           private String strPositive            public AlertDecision question  NonNull String question            this question   question          return this             public AlertDecision ansPositive  NonNull String strPositive            this strPositive   strPositive          return this             public AlertDecision ansNegative  NonNull String strNegative            this strNegative   strNegative          return this             public String getQuestion             return question             public String getAnswerNegative             return strNegative             public String getAnswerPositive             return strPositive            after a interface for return the result  public interface OnAlertDecisionClickListener                   Interface definition for a callback to be invoked when a view is clicked                 param dialog the dialog that was clicked         param object The object in the position of the view             void onPositiveDecisionClick DialogInterface dialog  Object object       void onNegativeDecisionClick DialogInterface dialog  Object object       Now you can create an utils for access easily  in this class you can implement different animation or custom layout for the alert    public class AlertViewUtils        public static void showAlertDecision Context context                                            NonNull AlertDecision decision                                           final OnAlertDecisionClickListener listener                                           final Object object             AlertDialog Builder builder   new AlertDialog Builder context           builder setMessage decision getQuestion             builder setPositiveButton decision getAnswerPositive                    new DialogInterface OnClickListener                         public void onClick DialogInterface dialog  int which                            listener onPositiveDecisionClick dialog  object                                                      builder setNegativeButton decision getAnswerNegative                    new DialogInterface OnClickListener                         public void onClick DialogInterface dialog  int which                            listener onNegativeDecisionClick dialog  object                                                      android support v7 app AlertDialog dialog   builder create            dialog show              and the last call in activity or fragment  you can use this in you case or for other task   public class MainActivity extends AppCompatActivity     Override     protected void onCreate Bundle savedInstanceState            super onCreate savedInstanceState           setContentView R layout activity           initResources               public void initResources             Button doSomething    Button  findViewById R id btn           doSomething setOnClickListener getDecisionListener                private View OnClickListener getDecisionListener             return new View OnClickListener                  Override             public void onClick View v                    AlertDecision decision   new AlertDecision                            question  question                                ansNegative  negative action                               ansPositive  positive action                        AlertViewUtils showAlertDecision MainActivity this                          decision  getOnDecisionListener    v                                       private OnAlertDecisionClickListener getOnDecisionListener             return new OnAlertDecisionClickListener                  Override             public void onPositiveDecisionClick DialogInterface dialog  Object object                       do something like create  show views  etc                                Override             public void onNegativeDecisionClick DialogInterface dialog  Object object                      do something like delete  close session  etc

Steve H s answer is spot on  but here s a bit more information  the reason that dialogs work the way they do is because dialogs in Android are asynchronous  execution does not stop when the dialog is displayed    Because of this  you have to use a callback to handle the user s selection   Check out this question for a longer discussion between the differences in Android and  NET  as it relates to dialogs   Dialogs   AlertDialogs  How to  quot block execution quot  while dialog is up   NET-style

All the answers here boil down to lengthy and not reader-friendly code  just what the person asking was trying to avoid  To me  was the easiest approach is to employ lambdas here   new AlertDialog Builder this           setTitle  Are you sure             setMessage  If you go back you will loose any changes             setPositiveButton  Yes    dialog  which  - gt                doSomething                dialog dismiss                        setNegativeButton  No    dialog  which  - gt  dialog dismiss             show      Lambdas in Android require the retrolambda plugin  https   github com evant gradle-retrolambda   but it s hugely helpful in writing cleaner code anyways
