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
                }
            });

    }
