How to get the DialogResult in android?

Question

I want to create a DialogAlert with two buttons 'YES' and 'NO'. I want to capture the result of the Dialog in a boolean variable. Suppose the user clicks the 'YES' button then the DialogResult Should return a true Value and if the user clicks the 'NO' button then the DialogResult should return a False value. Please help me out in doing this. Thanks in advance.

Answer 1

I would use a AlertDialog (see documentation here). If you have your own class DialogResult the the code could look something like this:

DialogResult result = new DialogResult(); 
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setMessage("Are you sure you want to exit?")
   .setCancelable(false)
   .setPositiveButton("Yes", new DialogInterface.OnClickListener() {
       public void onClick(DialogInterface dialog, int id) {
            // User clicked Yes: set the value to your result class here. E.g:
            MyActivity.result.setValue(true);
       }
   })
   .setNegativeButton("No", new DialogInterface.OnClickListener() {
       public void onClick(DialogInterface dialog, int id) {
            // User clicked No: set the value to your result class here. E.g: 
            MyActivity.result.setValue(false);
       }
   });
AlertDialog alert = builder.create();

Try this code

boolean result;
AlertDialog.Builder invalid_input_dialog = new AlertDialog.Builder(Select_party_foods1.this);
          invalid_input_dialog.setTitle("Event Organise")
          .setMessage(dialog_message)
          .setCancelable(true)
          .setPositiveButton("Ok", new DialogInterface.OnClickListener(){
              @Override
                public void onClick(DialogInterface dialog, int which) {
                 result=true;
                System.out.println("The result is "+result);
              }
          })
          .setNegativeButton("No", new DialogInterface.OnClickListener(){

            @Override
            public void onClick(DialogInterface dialog, int which) {
                // TODO Auto-generated method stub
                result=false;
                System.out.println("The result is "+result);                        
            }

          })
          .show();
