Question

In my Android application when an user touch an overlayItem on the map for more than 1.5 seconds an AlertDialog appear. I need user’s answer (alertDialogResult) to either keep the overlayItem or remove it from the map. However, after the AlertDialog inner-class get called, the outer-class continue it execution and at that point I do not have user’s answer.

Any suggestions? Any alternative to AlertDialog?

    final Boolean alertDialogResult = false;

        if ( ( pressEndTime - pressStartTime ) > 1500 )  {  

            AlertDialog.Builder alertDialog = new AlertDialog.Builder( mapView.getContext() );
            alertDialog.setTitle( "Warning!" );
            alertDialog.setMessage("Do you want to delete the selected overlayItem?");
            alertDialog.setCancelable(false);
            alertDialog.setIcon(R.drawable.ic_dialog_alert);

                alertDialog.setPositiveButton("OK", new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int id) {
                        dialog.dismiss();
                        alertDialogResult = true;


                    }   
                });

                alertDialog.setNegativeButton("No", new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int id) {
                        dialog.dismiss();
                    }

                });

            alertDialog.show();

            longPress = true;

            if ( alertDialogResult  == true ) {
                AndroidMainActivity.sendDeleteOverlayRequest(mapView, overlayItemId);
            }

Answer 1

Why do you need alertDialogResult flag, you can move

  AndroidMainActivity.sendDeleteOverlayRequest(mapView, overlayItemId); 

to onClick of positiveButton

Edit: Your AlertDialog will not wait for user Interatction after it has been Initialized. That is why there is callback for Onclick.
