Use this way

alertDialog.show();
alertDialog.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.argb(0, 200, 200, 200)));

I did this on custom alert dialog.

Values are like alpha, red, green, blue. Range from 0 to 255. Change values of alpha to get different degree of transparency

I don't know if this will help you. This is how i created my dialog box (its a prompt to user to try the app without log-in)

public void promptUser()
{       
    final Dialog requestDialog= new Dialog(MyActivity.this);
    requestDialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
    requestDialog.setContentView(R.layout.lyt_prompt_user);

    TextView requestTitle = (TextView) requestDialog.findViewById(R.id.request_title);
    TextView requestText = (TextView) requestDialog.findViewById(R.id.request_text);
    Button acceptButton = (Button) requestDialog.findViewById(R.id.request_accept);
    Button rejectButton = (Button) requestDialog.findViewById(R.id.request_reject);

    requestTitle.setText("Don't want to login?");
    requestText.setText("You can still explore the app with limited functionality.");

    acceptButton.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            // do something
            requestDialog.dismiss();
            finish();
            startActivity(intent);
        }
    });

    rejectButton.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            requestDialog.dismiss();
            (MyActivity.this).finish();
        }
    });

    requestDialog.setCancelable(false);
    requestDialog.show();
    requestDialog.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.argb(0, 200, 200, 200)));
}

I tried changing the alpha from 0 to 90, it shows a faint white background, somewhat glassy feeling.
