When dialog closed, you can use dialog.setOnDismissListener at the following code with the usage of an updated dialog code.

private void ShowDialog() {      
            View view = LayoutInflater.from(ActivityMain.this).inflate(R.layout.dialog, null);
            dialog = new Dialog(ActivityMain.this);
            dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
            dialog.setCancelable(true);
            dialog.setCanceledOnTouchOutside(true);
            dialog.addContentView(view, new RelativeLayout.LayoutParams(
                        WindowManager.LayoutParams.WRAP_CONTENT,
                        WindowManager.LayoutParams.WRAP_CONTENT));
            Button dialogBtn = (Button) dialog.findViewById(R.id.button);
            dialogBtn.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    dialog.dismiss();                
                }
            });
            dialog.setOnDismissListener(new DialogInterface.OnDismissListener() {
                @Override
                public void onDismiss(final DialogInterface arg) {
                    //when dialog closed
                }
            });

    }

I noticed that the onDismissListener is called even when you select one of the options in the alert (Yes/No/Neutral button). For me onCancelListener was the best option since I needed something that tracked an explicit closing of the dialog by clicking outside the alert area.

@Ken Wolf has a great answer to this question.

Just wanted to add that onDismissListener was only introduced in API 17. If you are trying to support something lower, you can use onCancelListener, which is not as good but covers cases like backButton and tapping outside of the AlertDialog.

http://developer.android.com/reference/android/content/DialogInterface.OnCancelListener.html#onCancel(android.content.DialogInterface)

public Dialog createDialog() {
    Dialog d = new Dialog(this);
    d.setOnCancelListener(new DialogInterface.OnCancelListener() {
        @Override
        public void onCancel(DialogInterface dialog) {
            // do something
        }
    });
}

You can use an onDismissListener

http://developer.android.com/reference/android/content/DialogInterface.OnDismissListener.html

public Dialog createDialog() {
    Dialog d = new Dialog(this);
    d.setOnDismissListener(new OnDismissListener() {
        @Override
        public void onDismiss(final DialogInterface arg0) {
            // do something
        }
    });
    return d;
}

If you are using a DialogFragment just override onDismiss()

http://developer.android.com/reference/android/app/DialogFragment.html#onDismiss(android.content.DialogInterface)
