How to check value before dismiss a dialog?

Question

I want to show a dialog. When click outside the dialog , i want dialog to get dismiss. But before dismissing a dialog, i want to check for a condition, if correct then dismiss the dialog, else if value is incorrect don't dismiss it.

Can anyone help me? Thank you.

There is surely a way to make this work but I will highly recommend you to use negative and positive button on your dialog box and setCancelable(false) (only if your app can not proceed further without the value entered by user) on it. — Varundroid, Oct 22 '14 at 04:44
Try to implement this interface : DialogInterface.OnDismissListener — Haresh Chhelana, Oct 22 '14 at 04:44

Keep setCancelabe(false); until the value in the EditText is not correct. use TextWatcherto check value, and whenever your value is correct then set setCancelabe(true);

You can check the value when inputting with TextWatcher. Or set custom onClickListener to the positive button.

AlertDialog.Builder builder = new AlertDialog.Builder();

// build dialog

AlertDialog dialog = builder.create();
dialog.setOnShowListener(new DialogInterface.OnShowListener(){

    @Override
    public void onShow(DialogInterface dialogInterface){


        ((AlertDialog)dialogInterface).getButton(AlertDialog.BUTTON_POSITIVE)
                                      .setOnClickListener(// check value here)


    }
}

dialog.show();

remember to invoke dialogInterface.dismiss() when you ready to dismiss it.
