Continue displaying AlertDialog if entered wrong password

I've successfully displayed an EditText in the AlertDialog. When entered text in the edit field, it is compared with a custom text. If the entered text doesn't match, the AlertDilaog should continue to show but currently the dialog is closing Positive Button is clicked, even if a wrong password was entered.

Do you guys have a solution for this?

UPDATED: Here is the code

builder.setView(v)
            .setPositiveButton("Ok", new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int id) {
                    EditText enteredPassword = (EditText) v.findViewById(R.id.enteredPassword);
                    if (enteredPassword.getText().toString().trim().equals(correctPassword.trim()) {
                        Log.i(TAG, "User Entered Right Answer");
                      } else {
                        Log.i(TAG, "User Entered Wrong Answer");
                        // Continue showing the dialog if Wrong Answer is entered
                        Toast.makeText(getApplicationContext(), "Enter a proper answer", Toast.LENGTH_LONG).show();
                    }
                }
            })
            .setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int id) {
                    dialog.cancel();
                }
            });

Yes, you can. You basically need to:

  1. Create the dialog with DialogBuilder
  2. show() the dialog
  3. Find the buttons in the dialog shown and override their onClickListener

So, create a listener class:

class CustomListener implements View.OnClickListener {
    private final Dialog dialog;
    public CustomListener(Dialog dialog) {
        this.dialog = dialog;
    }
    @Override
    public void onClick(View v) {

        // Do whatever you want here

        // If tou want to close the dialog, uncomment the line below
        //dialog.dismiss();
    }
}

Then when showing the dialog use:

AlertDialog dialog = dialogBuilder.create();
dialog.show();
Button theButton = dialog.getButton(DialogInterface.BUTTON_POSITIVE);
theButton.setOnClickListener(new CustomListener(dialog));

Remember, you need to show the dialog otherwise the button will not be findeable. Also, be sure to change DialogInterface.BUTTON_POSITIVE to whatever value you used to add the button. Also note that when adding the buttons in the DialogBuilder you will need to provide onClickListeners - you cannot add the custom listener in there, though - the dialog will still dismiss if you do not override the listeners after show() is called.

Change your code as Part 1 and use Part 2 just after you show the dialog

Part 1

builder.setView(v)
       .setPositiveButton("Ok", new DialogInterface.OnClickListener() {
           public void onClick(DialogInterface dialog, int id) {
               // Don't do anything here. Will override it later     
           }
        })
        .setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int id) {
                dialog.dismiss();
            }
        });

Part 2

dialog.getButton(AlertDialog.BUTTON_POSITIVE).setOnClickListener(new View.OnClickListener()
  {            
      @Override
      public void onClick(View v)
      {
          EditText enteredPassword = (EditText) v.findViewById(R.id.enteredPassword);
          if (enteredPassword.getText().toString().trim().equals(correctPassword.getText().toString().trim()) {
              Log.i(TAG, "User Entered Right Answer");
              disalog.dismiss();
          } else {
              Log.i(TAG, "User Entered Wrong Answer");
              // Continue showing the dialog if Wrong Answer is entered
              Toast.makeText(getApplicationContext(), "Enter a proper answer", Toast.LENGTH_LONG).show();
          }
      }
  });

You can use dialog.dismiss(); in your condition .

FYI

Use dialog.dismiss(); instead dialog.cancel();

Finally, Like this way

if (enteredPassword.getText().toString().trim().equals(correctPassword.getText().toString().trim()) {
                    Log.i(TAG, "User Entered Right Answer");
                      dialog.dismiss();
                  } else {
                    Log.i(TAG, "User Entered Wrong Answer");
                    // Continue showing the dialog if Wrong Answer is entered
                    Toast.makeText(getApplicationContext(), "Enter a proper answer", Toast.LENGTH_LONG).show();
                }

Please have a look

Try this...

dialogBuilder.setPositiveButton(R.string.ok, new OnClickListener()
    {
        @Override
        public void onClick(DialogInterface dialog, int which)
        {
            if(is text correct)
            {
                dialog.dismiss();
            }
        }
    });
